Hey man Great videos on the BH92. I'm in the process of buying 1 for my L6060. I was a fire sprinkler installer for many years and we would wrap the sprinkler heads at least 5 times around the threads. Never any leaks, mind you city water is never more than 150 psi. I have done repairs to my hydraulic system and Always used teflon tape. The problem with it is if you have extra hanging over the threads, it could potentially enter the hydraulic system. That is why there is a filter to catch that kind of crap. Don't let the negative Nellie Engels get to ya... You're doing a great service to us that need to figure things out! Take care man.
I have a great deal of respect for a man that admits his mistakes. Call it "a dumb thing" but really, we've all done it at least once or twice. Good video Toby!
I quit using Teflon tape a few years ago, I found it awkward to put on the threads and had leaks from time to time. For all my hydraulic and pneumatic connections I now use Locktite 545. The downside is you need to wait about 24 hours before use and it is expensive. The upside, no leaks and if you need to break and make the connection, easy thread cleanup. But like you said, to each there own, I'm happy because I found a better method for me. Thanks for sharing your assembly mistake, it makes me feel less stupid :)
Hello, thanks for the help offered and the calm way to explain technical features and details. Congratulations to as many achievable projects as possible. Good health.
Hey if that's all you messed up, id still call it a win. Big on you to admit your mistake and make a follow up video! Good videos thanks for the content!
Here in New Zealand my son has is own hydraulic service company he has workied in the hydraulic business for about 32 years as a serviceman and company manager he runs three service trucks and a worshop and is still hands on he always uses teflon tape on hydraulic lines it is the common thing here .like your Videos waiting to see the follow up on the Cat D2 Regards Les
I've heard all kinds of horror stories of using Teflon tape. I agree, it can get loose in your system(whatever you are working on), but like someone else mentioned, I never tape the first few turns. That helps keep small pieces from tearing loose and getting into the fluid stream. From what I recall, any tape/compound you use on the thread is more for lubrication of the threads so you can tighten it correctly. No different then oiling a bolt before torquing it on a motor. If you get a leak from using tape, you didn't tighten it enough to begin with. Or it has faulty fittings. Thanks for making great videos. Keep it up.
I've heard this "lubrication" theory. I don't buy it. If that was the case you could just use some grease. But try that and see if it works... The tape is a packing that is required because a pipe thread has a built in leak path: the thread itself. I use tape. It works fine. The paste works well too. I don't like the anaerobic thread sealer like that made by Loctite.
To add to your correct instructions, when undoing a teflon taped joint, it is then that one has to make sure to remove all of the tape that gets left in the threads of both the internal and external threads before putting the joint back together or better yet, right after disassembly . This is where a lot of people get lazy and this is where a lot of problems start.
Grinning and bearing it is the best part. I've always had to go behind everybody else's installation and run what was there. That is a better finished route but as people squawk about different brands, I ALWAYS say that it's whoever sits in the seat is what does the work and keeps the machine running and in one piece. If all the lines were inside the boom somebody would tear them off. You and Pop will keep that rig going. I've had to deal with screw-ups and gomms for about 50 years and it's still who sits in the seat, whether a 4-lever Ford, a foot swing Case or a 300 Komatsu trackhoe, it's still the seat warmer. Take care, Buddy! BLESSINGS and Hi Pop!
Whomever says you shouldn't use teflon tape on hydraulics is full of it!! Absolutely nothing wrong using teflon tape. I was going to comment on the first video then saw this one so, the one thing that would help you in assembly. (For future references), when putting in the pins, especially if only one end has the bolt holes for the fasteners, put the opposite end in first. You can see the holes and can align them much easier that way. Now, only real bad thing about your first and this video... we didn't get to see it in action. LOL P.S. Everyone makes mistakes, those that claim they don't are fools. You corrected your error and showed it on youtube, double thumbs up. Great 2 videos you made on this. Cheers :)
It's okay to use teflon tape as long as you apply it short of the end of the threads so no shards of tape can end up in the oil line. It's also a good practice to lube the taped thread with petroleum jelly to reduce shredding the tape. On steel pipe we would buff the threads on a wire wheel to remove any roughness before taping and installing. Rarely had a leak with this method.
Agreed, you could put an entire roll of tape on one fitting if you wanted to. As long as it was short of the bottom of the threads as you stated, it's impossible to get bits of tape in the hydraulic system.
Toby, I wouldn't beat yourself up about putting those brackets upside down. I know you're a mechanic by trade, but oversights happen to the best of us!! We help each other out by noticing things the other guy didn't at times. Nothing more to it than that !! As to teflon tape.....I use it all the time on all sorts of applications, simply making sure it's wrapped around the fitting correctly so it doesn't bunch up, and shred ending up where it's not wanted. Happy day to you !!
One of the reasons i watch your video's is the fact your human, when you mess up you own it. Many people on TH-cam simply delete mistakes like the one you just admitted, as for teflon tape I've been using it on truck and heavy equipment hydraulic systems for years and never had a problem.
I’ll touch that with a ten foot pole. In the late ‘70s we were told in tech school if you weren’t careful the tape would gather in the hydraulic system and plug it up. Well what are filters for? It wasn’t until later I realized it wasn’t only a seal as it was lubrication to help get a tighter fit on pipe thread. What drives me nuts is someone who puts Teflon tape on flare fittings that really just need to be tightened to form the metal to metal seal between the mating surfaces but yet the Teflon tape used on the threads will help you get the fitting tighter than a dry fitting. I like the Teflon paste a little better which the mechanics used on head bolts for lubrication and sealing into water jackets. Using nothing on pipe thread will only give you leaks.
I had to watch most guys talk about their life, intellect, cats, dogs and ect. Called them special things and got off.. Not you! I even told my wife, look, a good old-school guy. I appreciate your time.
I can’t help but notice that this was pop’s new toy, at mom’s insistence but it doesn’t appear that pop has gotten to touch it yet. Might be time for another video from dad wherein he can explain when and how he lost control of his vehicle. Just messin with ya, happy digging. 😎👍
NPT. Is national pipe thread. Use Teflon tape always! People can look it up in the machinists hand book. Your human you still did a fantastic job assembly it!
I'm curious how well you like the backhoe mounted on your tractor and how useful the thumb is? I hope you make a video of digging and moving some materials with it once you get a feel for operating the backhoe.
Squatch you made a mistake 😱 come on dude you were just testing us!😀 Seriously though you have no need to apologize for anything in your videos, I watch your channel for the interesting content and the knowledge you share with us, I DON'T come to your channel to pull you or your videos to peices, if I did that I would not bother watching TH-cam, not my style and certainly not when you put so much effort in making your videos, it's so easy to criticize from the armchair! Making a genuine mistake like you did with the piping brackets and someone pointing it out to you in my opinion is helpful comment, but don't be so apologetic about it, I have learned a hell of a lot through making mistakes in my time, over here we say ''you can't make an ommlete without breaking an egg''! As always great videos and thank you for putting in the time and effort to entertain us, all the best to you.
My OCD is saying "Cut the tail ends of those zip ties for an even cleaner look". Thx for the update. Thought you were going to do something about aligning that foot pedal better?
I am always impressed with your videos. Thank you for taking the time to film, edit and post. A few video's back you mentioned you were sorting out a problem with a too-long shaft that connects the foot pedal controlling the thumb to the hydraulic control shaft. How did that work out and will you have video of your fix?
Hi, I have use the Teflon tape before on all my projects and recently discovered Loctite 545 sealant. This product does work perfectly on any application or fittings.
Seeing all that tape I would go ahead and use it. It might help you in case you need to have any warranty work done. The dealer may assume that was a factory job.
Well done. Teflon tape, what if it wasnt used (if you were one to say never ever use it on hydraulics) and something went wrong later on and the manufacturer said it was your own doing because you did not follow installation procedures as laid down in the instructions ?. Yes, instructions are placed for man to ignore and do it his way. Yes, maps are printed by man but rarely used by man and it is imperrative for man not to ask for directions, lol. But Man is not 100% perfect (even if he says he is). We all make mistakes and learn by them. Great video. You didnt have to really make it but you did, which helps others too.
Teflon tape! Lol. I have owned and operated Hydraulic Excavators for years and have always installed tapered thread b.s.p. fittings 'dry', and they have never leaked, however, if the Kubota manual says use tape, I would use it! 👍
I am in the process in restoring a Kubota front loader backhoe set that I got out of a junkyard now. I will have a lot more work into mine getting it ready, many parts wore and needs TLC....
If I had never done something boneheaded by not looking at the directions I would be Making so much fun of you but I have so thanks for saying we're all human & not perfect keep making your great videos
Hi I have worked a lot on high psi air and hyds if you use teflon tape stay back a thread when putting it on. they had stopped us from using it because it was getting into valves and gages because people was putting it over the end of the fitting, they went to liquid teflon pipe dope
Hi Squatch. Now I know I'm wrong, but would n't the thumb hoses have a less tight bend with the fixings the other way round on the bucket end of the jib? I guess they are required to be installed that way to provide more protection. And please be careful with that 10 foot pole. I'm delicate! BobUK.
JUST WONDERING... The Kubota and Kioti seem similar ,, especially with the similar bracket / brace on the arm. I wonder if the hydraulic thumb will work on the Kioti since KIOTI for now only has a non-hydraulic thumb.
Will you install any inserts into the base of the stabilizers/outriggers? They are looking like they are missing but not necessary on a farm tractor/backhoe?? I did not notice nor will I tell anything regarding the brackets!! A smile came over me when you told us! Still an excellent video!!
Also not to stir the pot about Teflon tape, but, I have noticed my self running the tape out past the end of the fitting leaving some of it flapping which could break off and get into somewhere. So I just make sure that I only apply it to the upper portion of the thread which will be covered over and there is none to break off. The Teflon tape does two things: act as a seal for the threads and act as a lubricant for the threads to get them tighter. You can use other things, such as Locktite sealant which cures hard but won't work as a lubricant. Or graphite grease which will work as an excellent lubricant but not sealant. With proper application, I have had no problems with the Teflon tape.
@1:19 take the hoses off again and flip the brackets so the fitting is hanging over the top of the boom. this straightens out the hose run even more and reduces chances of it snagging. have a quick look.. i don't know if it will interfere with the upper dipper cylinder body. but it sure looks like it will fit better that way.
As a rule I use T-tape or never-seize on similar metals (iron to iron) and none on dissimilar (brass to iron). But I'm a locomotive steam fitter so what do I know about hydraulics ? Have a good day and thanks for sharing.
Those brackets you had upside down almost look like they need to be swapped from side to side which would bring the lines inside of the boom instead of sticking out ?
I was alway told the fastest way to find a faults statement was to look for the words always or never. I use thread sealant myself but sometimes that is just not enough.
I think best solution to any Teflon tape issues is just have equipment that uses o-ring connections instead of pipe then you don’t have to worry about it. Lol 😎
Except now you have the issue of the "O" rings going bad. Either way, you end up "breaking" the hose connections apart. I have both on my farm, can't say either is better than the other. Both are time consuming when it comes to repairs. Cheers :)
Ham68 You didn't mention that the o ring type connections are also perpetual leak factories, so I just took care of that for you. I used to operate a Cat 988A model built in 1976. I can tell you very truthfully that it was a rolling hydraulic leak no matter how many o rings you changed. They would be leaking again in two weeks time or less.
@@ralfie8801 You must have either used poor oil, poor o-rings or had a hydraulic system that was overheating. The last reason is actually the most common reason we see for repeat o-ring failures. I have machines that are 30 years old with 5000-10000hrs use and the original o-rings and not even signs of sweating moisture at the connections. All the designs have their advantages and disadvantages.
bcbloc02 None of those things were poor.......Cat square o rings and metal backed seal kits, Chevron hydro fluid, oil not overheated. The only thing that was poor was the design of the connections.
Ralfie and yet cat still uses them today. I would think the warranty claims would have ate them alive until they changed the design to pipe threads or all welded connections.
Alot of the time the pressure is high enough that they self bleed. Sometimes this isn't the case, but normally working the cylinders in and out will squeeze any air out.
If i had asamble the hydraulik lines, i had turn the holders to sit 360 degres under the bomcylinder. Now are thay in a were possition to the objekt like tree and thing like that.
The only issue I see with Teflon tape is with the guys who put it on backwards of the threads or sloppily so it covers the hole and ends up getting in where it shouldn't be.
I do alot of hydraulics and have seen alot of different things, each manufacturer has its own tidbit to add i just do it and go on. Then if it doesnt work i adjust course and move on to much technical data to dive into on some of that
Hey, don't beat yourself up.. I usually do things wrong the first 3 or 4 times... You know, just to make sure that there aren't any alternative ways to do it before doing it the right way. LOL.
Toby, No problem on the fitting bracket mix-up. It happens (even with the instructions rt there). It's easy when doing an involved assembly like that to overlook things. We've all done it & anyone who says they haven't is either a liar or hasn't done much assembly work. As to the Teflon tape issue, where you used it & where Kubota used it, it's perfectly OK. The place it's not advisable to use it is on flare or ferrule (brass sleeve) fitting connections. There people who believe in using it & others who don't. Comes down to personal preference or what works best for the individual doing the work based on their past experiences. Thanks for the update & Good professional looking job !! Look forward to the next endeavor you share with us.
as long as you make sure you don't get it over the opening of the pipe fitting you can use teflon tape on hydraulic work for the past 30 years and used hydraulic Teflon tape on hydraulic 7% there is nothing wrong with using Teflon pay as long as you keep it from the end of the hose itself be opening
If that is normal tapered pipe thread then it will seal perfectly without anything on it. No teflon tape nor flax is needed to make it seal. Some people say that you can use teflon tape anyway, to prevent it from sticking, if you want to be able to take it loose sometime in the future. It's no big deal. As Mike Haduck would say. Just put it on there. It's no big deal.
This is why I hate pipe thread fitting for hydraulic and I usually change them out to a o-ring face or a DIN type o-ring seal. Cat makes nice ORS face seal also as you a CAT guy, and with addition of o-rings you have better sealing to a much higher pressure.
That you made a mistake shows your human, that you owned up to it & corrected it shows your a man,
Thanks for another great video.

Hi, he that has never made an error has done nothing!!! Thanks for all the brilliant videos.
I have a great deal of respect for a man that admits his mistakes. Call it "a dumb thing" but really, we've all done it at least once or twice. Good video Toby!

Hello, thanks for the help offered and the calm way to explain technical features and details. Congratulations to as many achievable projects as possible. Good health.
Darn nice looking machine - will be very handy! Thanks for including us Toby!
Hey if that's all you messed up, id still call it a win. Big on you to admit your mistake and make a follow up video! Good videos thanks for the content!
Here in New Zealand my son has is own hydraulic service company he has workied in the hydraulic business for about 32 years as a serviceman and company manager he runs three service trucks and a worshop and is still hands on he always uses teflon tape on hydraulic lines it is the common thing here .like your Videos waiting to see the follow up on the Cat D2 Regards Les
I've heard all kinds of horror stories of using Teflon tape. I agree, it can get loose in your system(whatever you are working on), but like someone else mentioned, I never tape the first few turns.

I've heard this "lubrication" theory. I don't buy it. If that was the case you could just use some grease. But try that and see if it works...

I don't like the anaerobic thread sealer like that made by Loctite.
Teflon used correctly will not cause a problem, leave the first two threads bare and you shouldn't have concerns! Great Video's!
That's exactly what I do.
To add to your correct instructions, when undoing a teflon taped joint, it is then that one has to make sure to remove all of the tape that gets left in the threads of both the internal and external threads before putting the joint back together or better yet, right after disassembly . This is where a lot of people get lazy and this is where a lot of problems start.
Very impressed i am your neighbor in Willow River and purchased my vehicle where you work i work on old tractors also
Thank you for the video.If installing the brackets upside down is the only mistake you made your in real good shape!
Grinning and bearing it is the best part. I've always had to go behind everybody else's installation and run what was there. That is a better finished route but as people squawk about different brands, I ALWAYS say that it's whoever sits in the seat is what does the work and keeps the machine running and in one piece. If all the lines were inside the boom somebody would tear them off. You and Pop will keep that rig going. I've had to deal with screw-ups and gomms for about 50 years and it's still who sits in the seat, whether a 4-lever Ford, a foot swing Case or a 300 Komatsu trackhoe, it's still the seat warmer.
Take care, Buddy! BLESSINGS and Hi Pop!

We have all been there more than a few times. Welcome to the club.
You have a really nice machine! Thank you for sharing. Have fun digging!
I think you were just testing you tube with the brackets upside down. Great install and thanks for sharing.
Excellent job. Have been thinking about getting the BH92; your video helps to make the decision. Thanks.
Teflon tape is fine to use on hydraulics... but trim those zip ties!! lol
Good video Toby. Looking forward to seeing it at work.
Always appreciate your videos!
Love your videos love your old dozers
Thanks and keep up the great work. I thought I had made a mistake one time. But I was wrong, until my wife told me so.
Perhaps those brackets should also be spun around 180 so that the fittings are over the boom and not out beside it. Just a thought.
Squach as a trained mechanic teflon tape should be used all fittings except brass/bronze fittings this via old school training.
Nice from the guy who spot that bracket, well done
I love factory.
Keep up the good work I'm proud of you
I’ll touch that with a ten foot pole. In the late ‘70s we were told in tech school if you weren’t careful the tape would gather in the hydraulic system and plug it up. Well what are filters for?

We are only human buddy mistakes happen , love the videos

Cant mess up if you dont do anything. Great video, Thanks! Also, teflon tape is fine on hydraulics if your not dumb with the installation.
All lines in all the years I work we always used Teflon tap
Hi Squatch. Now I know I'm wrong, but would n't the thumb hoses have a less tight bend with the fixings the other way round on the bucket end of the jib? I guess they are required to be installed that way to provide more protection. And please be careful with that 10 foot pole. I'm delicate! BobUK.

If the book says to do it that way. Then you do it that way. Thanks for the great video.
JUST WONDERING... The Kubota and Kioti seem similar ,, especially with the similar bracket / brace on the arm. I wonder if the hydraulic thumb will work on the Kioti since KIOTI for now only has a non-hydraulic thumb.

I like to use blue loctite on npt fittings. I've had pipe dope and thread tape leak before. Never had loctite leak.
As a rule I use T-tape or never-seize on similar metals (iron to iron) and none on dissimilar (brass to iron). But I'm a locomotive steam fitter so what do I know about hydraulics ? Have a good day and thanks for sharing.
Those brackets you had upside down almost look like they need to be swapped from side to side which would bring the lines inside of the boom instead of sticking out ?
any up date about the foot control for the Thumb?
Teflon tape, pipe threads, Gotta have it.... just went through all that on my JD.
What was the total cost of the backhoe attachment
I have a BH77 backhoe with a Kubota Mechanical thumb. I can’t believe there isn’t a kit out there that fits.... have you heard of any?
Thank you sir
Im.super jealous and I WANT ONE BAD NOW!!!
How did you fix the issue with the valve on the thumb?
I was alway told the fastest way to find a faults statement was to look for the words always or never.
I use thread sealant myself but sometimes that is just not enough.
A BIGGER hammer.

thats so true , only People who never actually have worked make no mistakes !

I think best solution to any Teflon tape issues is just have equipment that uses o-ring connections instead of pipe then you don’t have to worry about it. Lol 😎
Except now you have the issue of the "O" rings going bad. Either way, you end up "breaking" the hose connections apart. I have both on my farm, can't say either is better than the other. Both are time consuming when it comes to repairs. Cheers :)

You didn't mention that the o ring type connections are also perpetual leak factories, so I just took care of that for you. I used to operate a Cat 988A model built in 1976. I can tell you very truthfully that it was a rolling hydraulic leak no matter how many o rings you changed. They would be leaking again in two weeks time or less.
@@ralfie8801 You must have either used poor oil, poor o-rings or had a hydraulic system that was overheating. The last reason is actually the most common reason we see for repeat o-ring failures. I have machines that are 30 years old with 5000-10000hrs use and the original o-rings and not even signs of sweating moisture at the connections. All the designs have their advantages and disadvantages.

None of those things were poor.......Cat square o rings and metal backed seal kits, Chevron hydro fluid, oil not overheated. The only thing that was poor was the design of the connections.
Ralfie and yet cat still uses them today. I would think the warranty claims would have ate them alive until they changed the design to pipe threads or all welded connections.
Tell us about fixing the thumb foot petal
I was taught start 1 thread down from end with tape. Don't leave hanging off as to avoid becoming loose and clogging a valve or whatever.
Complete hydraulic newb here, I can't help wondering, how do you bleed/purge the system from any air pocket ?
Alot of the time the pressure is high enough that they self bleed. Sometimes this isn't the case, but normally working the cylinders in and out will squeeze any air out.
I put togather John deer equipment for yrs and have always used tape.
If i had asamble the hydraulik lines, i had turn the holders to sit 360 degres under the bomcylinder. Now are thay in a were possition to the objekt like tree and thing like that.
The only issue I see with Teflon tape is with the guys who put it on backwards of the threads or sloppily so it covers the hole and ends up getting in where it shouldn't be.
I would go with the factory instructions on teflon tape for warranty purposes.
When l first saw it I thought It was strange that the hoses would block the Kubota logo decal !
I do alot of hydraulics and have seen alot of different things, each manufacturer has its own tidbit to add i just do it and go on. Then if it doesnt work i adjust course and move on to much technical data to dive into on some of that
Hi. Could you give me the length of the cylinder, open and closed? I would fit something... Thanls.
THE ONE THING I NOTICED! Was your teflon tape was put on wrong side out and turned on backwards.......
How did you resolve the problem with the thumb foot-peddle control? Did you have to modify the parts?
I was going to ask the same question.
I was guessing he flipped the bracket/bushing so the long side was towards the peddle.
No harm, no foul.
If you change the brackets side to side they will be more protected by putting the fittings over the arm
Hey, don't beat yourself up.. I usually do things wrong the first 3 or 4 times... You know, just to make sure that there aren't any alternative ways to do it before doing it the right way. LOL.
Wait what you didn't delete the video modify it and reload it 😲
Thumbs up
As long as it's used correctly Teflon tape is fine. It becomes an issue when it's put on the threads sloppy.
🤣🤣good for you💪🏻💪🏻
The only thing that can be used to seal pipe thread is pipe dope or teflon tape , And pipe dope can really contaminate a hydraulic system .
Toby, No problem on the fitting bracket mix-up. It happens (even with the instructions rt there). It's easy when doing an involved assembly like that to overlook things. We've all done it & anyone who says they haven't is either a liar or hasn't done much assembly work.
As to the Teflon tape issue, where you used it & where Kubota used it, it's perfectly OK. The place it's not advisable to use it is on flare or ferrule (brass sleeve) fitting connections. There people who believe in using it & others who don't. Comes down to personal preference or what works best for the individual doing the work based on their past experiences.
Thanks for the update & Good professional looking job !! Look forward to the next endeavor you share with us.
as long as you make sure you don't get it over the opening of the pipe fitting you can use teflon tape on hydraulic work for the past 30 years and used hydraulic Teflon tape on hydraulic 7% there is nothing wrong with using Teflon pay as long as you keep it from the end of the hose itself be opening
If that is normal tapered pipe thread then it will seal perfectly without anything on it. No teflon tape nor flax is needed to make it seal. Some people say that you can use teflon tape anyway, to prevent it from sticking, if you want to be able to take it loose sometime in the future.
It's no big deal. As Mike Haduck would say. Just put it on there. It's no big deal.
They make teflon tape for hydraulics
Teflon is impervious to most fluids, I wouldn't worry about it.
That thumb hose bracket should have been turned 180 so the hoses would be inboard and the hoses would run straight down the boom
This is why I hate pipe thread fitting for hydraulic and I usually change them out to a o-ring face or a DIN type o-ring seal. Cat makes nice ORS face seal also as you a CAT guy, and with addition of o-rings you have better sealing to a much higher pressure.
