If I may be so bold Josh, as a farmer, I think of a custom machine shop not as a machinist but as a problem solver....a magician. A Repair Engineer if I may coin a phrase. Almost anyone can make chips. Heck, I have a "machine shop" so I can make chips. Your value to us is your brain. SNAP! "Oh crap, a new part is $1,500 and two weeks away....how am I going to fix this? Let's go see Josh he can do it". Good job. Love the content. P.S. Sometimes we need a skid steer because a wheel loader is too big.
This crankshaft came out of a 610 Melroe Bobcat. There is no center main on the crank so it’s understandable how it’s slightly bent without being noticed. Agreed they should have still noticed it tho. We greatly appreciate your work as the taper and the keyway weren’t something my husband could do (he is an ASE Certified Engine Machinist). BTW- your Customer (76 years old) was very happy you were able to do this for him 💕 He has had that skid loader for about 35 years with the same motor. Now he can run it again.
I'm surprised that crankshaft machined as easy as it did. I was expecting something much harder. This was one job that I was nervous for you from start to finish. Great job with it Josh
There's no way the shop that did the grinding didn't notice the shaft was bent, they probably just didn't say anything so they could get paid, no scruples. Great video like always Josh, thank you for uploading. 👍👍
The engine shop either missed it or didn't care, likely the latter. To be honest, you got bit by yourself by not checking the piece beforehand. You got it figured out, and it turned out excellent! I'm glad you are passing your knowledge on to the next generation.
@@TopperMachineLLC You do now! I have learned in my 59 years, to assume nothing. especially with things that someone else worked on or is used. From the sad but true department comes this... Even new stuff can be messed up from factory or shipping goons. Gotta check things...everytime.
Nice job Josh. I do agree that the Crankshaft grinder should have caught the bent shaft. But you did a good repair. Thanks for sharing. Have a great day. 👍
I recognize that pulley any day. It's out of a Bobcat loader. I grew up working on them and operating them as a kid in my father's shop and on the farm.
This is the exact job they got me into machining. Had an old bobcat 610 that needed an engine. A local guy attempted the exact modification as you did, but ended up with about .100” runout on the taper. Picked up an old atlas lathe and redid it myself. As the crank was forged, it was possible to build up with weld And remachine. Both machines are long gone and upgraded along the way, but that’s where it started! Thanks for sharing
Great content. Thank you for helping to save another old Melroe 600 or 610. For me it's not about utility it's about proving to myself that I can take a really old piece of equipment and make it usable again.
Great job on the crank. I love your videos because I ran a lot of the machinery doing the same type of repairs that you do. During my apprenticeship our shop tech instructor was a tool and die maker and always said “ Nothing is chiseled in stone. “ So ignore the negative comments. Everyone will have different methods, the end result is important. Good stuff.
I think you’re better at automotive work than you think! It’d be cool to see you jump into more stuff that challenges and annoys you lol. It makes for great video!
This job really did not bit you in the butt, but it gave you an opportunity to straighten out a bent shaft - I'd say that was a win-win in my book! Thanks for sharing!
Crankshafts are either forged and basically made from rock, so they will break all of your bits. Or they are cast but hardened and basically made from glass filled with peanut butter, and will break all of your bits.
Good video Josh. You found an issue with the crank and fixed it properly for the customer. I never did much engine repair work when I was a machinist but I'm pretty sure I would have assumed the crank was straight from the grinding shop. Having said that, it's great to watch your videos, I always learn something from them.
Pretty cool sir, when I seen the old school Wisconsin crank shaft it took me back about 40 years when I was a young man on the farm. We had several of those old air cooled engines . Great job too!
Crank alterations are difficult. You can make the whole assembly much more solid by installing a bolt and nut as a jacking screw opposite the big end journal's. That way when you put pressure on from the tailstock it doesn't deflect it. You can also use four jaw chuck and throw chuck end off and just get final journal and portion next to live centre running true. You have done an amazing job.
"LIKE" button has been torqued to the manufacturer's recommended specification. "CLICK". God forbid you should be running around with a loose "LIKE" button !
Take on jobs we KNOW we shouldn't take on. And then take them again the next time they come around... Small business life. You have great editing on your videos. Keep up the good work.
Josh, Ya did it again, great job !!!! That start on the interupted cut on that hardened shaft had my pucker factor on HI.....Your taper attachment saved the day, that and your attention to the fine details. Raining here again/still.....things aren't rusting, they are friggin molding....LOL....12 cord of firewood and can't even get em dry enuf to stack to dry !!!! Don
The tail shaft wasn't that hard. I'm guessing just the journals were hard. But it came out good. We've been getting some rain, but nowhere near enough. Hopefully we don't get dumped on this winter again. Don't think I can take that again.
Working on stuff other shops have worked on is always a gamble, you threw aces! You have great content that is so relateable. Great video and we are always learning new way of skinning a cat!
nice work...and I suspect it was not too easy to find out where the part was bent...glad it was only on the end you could cut off though, that doesn't happen too often. Thanks for sharing
I just bought a lathe wanting to be like you. It's sorta fun hunting all the parts needed to get it going...almost there. In the mean time, I have a good time disassembling & cleaning all the parts that actually lets me learn everything about it.
I completely rebuilt it several years back. I got in a quote for a big taper job and decided I'd better go through it. I got the job, and got very good at using the taper attachment.
I would have started the tap in the end of the shaft while the steady rest was in place using a spring-loaded center in the tailstock to guide the tap. Other than that, I was impressed with your approach and the results you got. I always enjoyed using the taper attachment on the Cincinnati tray top I worked with years ago.
It's leaving a lot better than it came in Josh, guessing after this video, you'll be getting more requests for automotive work 😮😊. Great job, and video. Thanks for sharing
Wondering if part of your walk is from the balance. Had a similar problem a few years ago, indicated in fine but after cutting it was out about 9 tenths. Ended uo putting bob weights on the journals and it cut fine. Love your stuff, especially the giant sawr blade!
I have been a home shop machinist for many years. I have made antique car parts, repaired them, designed and built cyclecars. And I have turned tapers on crankshafts. I don't have any problems with customers who want auto parts machined! Learn by your mistakes and don't blame them on others and you will do a better job and become a more accomplished machinist. I still like your videos, keep it up.
The problem isn't the work. It's the fact that the customer thinks I can do it cheaper than an automotive machine shop with their specialized equipment. Engine machining is totally different in tools and equipment. Something I have none of, nor do I want it. I am a professional shop doing industrial work, far from a hobbyist. When you're doing this for a living, a 20 minute job at the engine machine shop can be a 3 hour job at a regular machine shop. The customer doesn't want to pay that difference, and I don't want to waste my time on a underpaying job. I have no problem doing engine work on steam engines or prairie tractors pre 1930, but again that's a whole different thing.
Did the interrupted cut along the shaft cause the warp? The constant percussion along that particular line, perhaps. I hate interrupted cuts like that. I once put a very small sloped shoulder on the leading edge which seemed to help, and didn't seem to affect the holding power of the keyway later.
It is a bugger when you get caught up in something, not even in a nightmare could you envisage. I find that playing at home that happens rather frequently, I am always looking for the circling Blue Bird of Happiness. Rather good save... Goodonya
I know that crankshaft, mine is out of a 610 Bobcat, the engine was locked up all 4 cyls and broke every stud that held the heads down. I made a drill bushing for the studs and got all of them out, was able to knock out all 4 pistons and reuse them knurling the skirts, I aggressively honed the cylinders to .010 oversize and file fit a new set of rings to the cylinders. This was done over about a month. Got it back together and have been using it since 2012. Does not use any oil and runs perfectly. The only way this was possible was that I have a machine shop in my basement. These are things you do for yourself, this machine was junk before it got to me.
Not only that, but it always brings in the cheapest people. I now just tell people I'm not an automotive machine shop and therefore don't have the tooling and equipment. Then they like to argue that it's only a 10 minute job. But it's the 2-3 hours of setup they don't want to pay for. Not worth my time. But this was kind of an exception. No automotive machine shop would be able to handle this.
Hi. That was a tricksy little bugger with the bent shaft. I just wondered why you didn’t just tap the thread on the lathe while the crank was in the fixed steady?
Good job! Just wondering though... Did you also measure the center main bearing to see where the bend was? I don't remember seeing that part. Also wondered if maybe they just left the end of the crank rough machined to the largest size so the customer could custom match it to whatever clapped out drive mechanism they had?
Was there a big chunk missing from the rim of the hub? Doesnt that cause problems when its running? (I know its not strictly part of the crankshaft you were working on).
Good job on crank modification, I bet that crank is out of a vf4d Wisconsin engine in a 610 Bobcat skid loader. Worked on them when dinosaurs roamed the earth. What you did is the only thing that can be done because Wisconsin has been out of business for awhile.
Did you see how much the shaft dipped when you put your tail stock in the new center hole? The shaft end in your chuck is not concentric. I hope this crank shaft isn't a waste of time since it isn't all that straight. How did that work out? It has been 9 months now...surely it got installed and used by now. Seals and bearings would suffer if that bend is a problem.
Well, I guess you were up for the challenge. I am glad that things worked out. I am thinking that if the shaft is to long that there may be other things that are not right. Thanks for the video. You are always interesting. I see that Rocky was there for support.
The crank that Josh turned down was out of a Owatonna Swather VHFD (in case people wanted to know) Same kind of pulley setup, but obviously didn’t work 🤷♀️
Hello Josh , nice job on the shaft . I was interested in how you set up to cut the taper . I've got 1943 Monarch CY16 with the same taper attachment but I've never used it , maybe some time in the future you could go into more detail on how to set it up .I was also wondering what model is your machine ?
If you have never used it, you probably should tear it down and rebuild it. There are several small bearings in it that will need to be replaced. They are super handy once you figure it out. Mine is an 18CU, I also have a 12CK
I got the machine about a year and a half ago , it had a few issues that I fixed , I did replace all the bearings in the taper attachment . I took the oil lines off in the head stock to make sure they were clear , replaced one metering valve that gos to the sight glass . Now I have an issue with no oil dripping out . I hope to do some work with this machine some day . Thanks for the videos@@TopperMachineLLC
You can water down anchor lube and use it in one of those blunt-syringe squeeze bottles. I see that lots of channels are pushing this stuff lately. If you're sponsored, you should say. We still trust your experience but if you're getting a kick back, you should disclose that you have an interest.
If I mention a product, it is sponsored. But rest assured, I will not promote garbage. If it didn't work, or I didn't like it, I'd never promote it. I did quite a bit of testing with anchorlube before using it on a video. It really is good stuff.
@@TopperMachineLLC Duly noted. I think I'm reacting to Vevor getting their tenticles into the youtube shop scene, which I find annoying. Everyone at the same time. Anchor Lube is also in a big promotion currently but it's already got a good reputation, so it is less bothersome. Keep up the good work. 60k!
@@neffk Vevor has reached out to me a few times and want me to try their crap. They always suggest a product, and I counter with one I actually want to try. They never get back to me. They actually have a product I would like to try out and actually would use, but they don't follow through. As for anchorlube, I have nothing bad to say about it. I think it is a great product with so many benefits.
Josh you are good at what you do I love machine work between you and CEE and Keith rutger I love these videos abom 79 went Hollywood what ever happened to Keith fenner from cape cod
The keyway for the flywheel on the Bobcat crank worked loose and got all tore up. 35 years of just him running it wasn’t bad to just finally let go right!?
@cylheadman was it a spun bearing on the swather engine then? It has been a while and I know i have details messed up. I could have sworn he said it was a Gehl skid steer also. I need to start writing these details down.
@@TopperMachineLLC it was a spun bearing on the bobcat. The Swather was fine and a decent donor. He probably rattled so many names and points in time. He never had a Gehl but they took Wisconsin engines so maybe he was rattling a list. He’s not the easiest 76 year old to follow 😂
Very nice job. That old Monarch with taper attachment is a wonderful machine. Do they run that VH4D (or whatever) on propane? I love my old Wisconsin AGNDs and others, but an Isuzu diesel would be a better choice.
Wouldn't you be better off cutting that output shaft to length FIRST using the steady rest without concern that you'd mark up the surface on the portion of the shaft you're gonna cut away anyway when you make the taper? (order of operations question) Edit: Seems like you morphed to that approach (circa 10:00) once you realized you had the slight bend in the shaft
Likely your tapor setting just changed when you changed over to steady. Tip with roller steady- get a say 6" dusc of 1/8 ish packing rubber - wad punch a centre hole marginally bigger dia. than the shaft fit to reduce risk of swarf going under rollers - not nice - I did it when an apprentice on an approx 4" prop shaft.
This! This comment! Absolutely something I didn't consider, but absolutely a possibility. I didn't notice a problem until I turned the end of the shaft.
@TopperMachineLLC plus you could use the middle bearing of the crank to support it by the steady rest: very small change that a bit of swarf destroys the bearing surface.
Dear Mr.Topper, it seems at some point in time, you got spooked with auto parts machining. Machining a part is machining a part, auto or not. Hang in there. New viewer, like your videos.
Old one was bad. Parts are not as available as they used to be. He had this one laying around and had it ground and ready to go. He didn't know the old one was different until he took it apart.

There was considerable pucker factor on this one.
The crankshaft was probably nodular iron which provides very good bearing surfaces and is relatively easy to machine.
There's no way the shop that did the grinding didn't notice the shaft was bent, they probably just didn't say anything so they could get paid, no scruples.
Great video like always Josh, thank you for uploading. 👍👍

Place a shim between the live center and the shaft center. A triangle shim cut to 30 degs works good.
You can get the tir to .001 or less.
Always enjoy watching your methods. Thank You

Wisconsin v4 engines have no center main. This was a used, but reground crank out of something else. End of the shaft was definitely bent.

Yes there was, and considering parts are not available, he has to use it.

Well, I guess you were up for the challenge. I am glad that things worked out. I am thinking that if the shaft is to long that there may be other things that are not right. Thanks for the video. You are always interesting. I see that Rocky was there for support.
Wisconsin had all kinds of different output shafts but in all, the cranks were all the same.
The crank that Josh turned down was out of a Owatonna Swather VHFD (in case people wanted to know)
Same kind of pulley setup, but obviously didn’t work 🤷♀️
Hello Josh , nice job on the shaft . I was interested in how you set up to cut the taper . I've got 1943 Monarch CY16 with the same taper attachment but I've never used it , maybe some time in the future you could go into more detail on how to set it up .I was also wondering what model is your machine ?
If you have never used it, you probably should tear it down and rebuild it. There are several small bearings in it that will need to be replaced. They are super handy once you figure it out. Mine is an 18CU, I also have a 12CK
I got the machine about a year and a half ago , it had a few issues that I fixed , I did replace all the bearings in the taper attachment . I took the oil lines off in the head stock to make sure they were clear , replaced one metering valve that gos to the sight glass . Now I have an issue with no oil dripping out . I hope to do some work with this machine some day . Thanks for the videos@@TopperMachineLLC
You can water down anchor lube and use it in one of those blunt-syringe squeeze bottles. I see that lots of channels are pushing this stuff lately. If you're sponsored, you should say. We still trust your experience but if you're getting a kick back, you should disclose that you have an interest.
If I mention a product, it is sponsored. But rest assured, I will not promote garbage. If it didn't work, or I didn't like it, I'd never promote it. I did quite a bit of testing with anchorlube before using it on a video. It really is good stuff.
@@TopperMachineLLC Duly noted. I think I'm reacting to Vevor getting their tenticles into the youtube shop scene, which I find annoying. Everyone at the same time. Anchor Lube is also in a big promotion currently but it's already got a good reputation, so it is less bothersome. Keep up the good work. 60k!
@@neffk Vevor has reached out to me a few times and want me to try their crap. They always suggest a product, and I counter with one I actually want to try. They never get back to me. They actually have a product I would like to try out and actually would use, but they don't follow through. As for anchorlube, I have nothing bad to say about it. I think it is a great product with so many benefits.
Josh you are good at what you do I love machine work between you and CEE and Keith rutger I love these videos abom 79 went Hollywood what ever happened to Keith fenner from cape cod
Keith Fenner is still active. Just more so on another platform.
That certainly was a tricky job, but you nailed it. I'm really wondering what was wrong with the old crankshaft that it needed to be replaced.
He spun a bearing, and just decided to have this one ready to go before tearing it down. Once he tore it down, he found the shafts were different.
The keyway for the flywheel on the Bobcat crank worked loose and got all tore up. 35 years of just him running it wasn’t bad to just finally let go right!?
@cylheadman was it a spun bearing on the swather engine then? It has been a while and I know i have details messed up. I could have sworn he said it was a Gehl skid steer also. I need to start writing these details down.
@@TopperMachineLLC it was a spun bearing on the bobcat. The Swather was fine and a decent donor.
He probably rattled so many names and points in time. He never had a Gehl but they took Wisconsin engines so maybe he was rattling a list. He’s not the easiest 76 year old to follow 😂
Really nice work a pleasure to watch video Thanks.
Excellent job Josh, I don't like working on engine parts either but sometimes it pays, lol, great video, keep'um coming..
How was the shop able to grind the crank accurately if it was bent?
Good question
Josh, Is there a reason you did not tap the hole with the job in the lathe after you finished the taper?
Control. Last thing I want is to break the Tap in the crank shaft. At least by hand, I can feel when I am in trouble.
@@TopperMachineLLCGood answer
Very nice job. That old Monarch with taper attachment is a wonderful machine.
Do they run that VH4D (or whatever) on propane? I love my old Wisconsin AGNDs and others, but an Isuzu diesel would be a better choice.
Just gas. Hardly anyone uses propane unless inside a industrial plant.
@@TopperMachineLLC Right. Makes sense, thanks.
VH4D Wisconsin motors were used for many many years in manufacturing of tobacco harvesters down here in the south which looks like what you had ?!
Wouldn't you be better off cutting that output shaft to length FIRST using the steady rest without concern that you'd mark up the surface on the portion of the shaft you're gonna cut away anyway when you make the taper? (order of operations question) Edit: Seems like you morphed to that approach (circa 10:00) once you realized you had the slight bend in the shaft
Good job indeed. Thanks for uploading this video.
It may have bit you, but you bit right back! You’re a skilled dude. Don’t sell yourself short. You did a good job, buddy.
I appreciate that!
Old mechanical skid steers are starting to be worth money in some places.
That is because the new ones are serious money. I don't like them, but I guess it's better than a shovel and wheelbarrow.
always great content Josh, cheers from Florida, Paul
Likely your tapor setting just changed when you changed over to steady.
Tip with roller steady- get a say 6" dusc of 1/8 ish packing rubber - wad punch a centre hole marginally bigger dia. than the shaft fit to reduce risk of swarf going under rollers - not nice - I did it when an apprentice on an approx 4" prop shaft.
Really good content thanks for sharing! But I know how aggravating it is I had one that I did awhile back.experience is the best teacher!
Great work Josh!
Did it work in the engine ?
Could changing the keyway be the reason that it started to bend?
This! This comment! Absolutely something I didn't consider, but absolutely a possibility. I didn't notice a problem until I turned the end of the shaft.
@TopperMachineLLC plus you could use the middle bearing of the crank to support it by the steady rest: very small change that a bit of swarf destroys the bearing surface.
@@therealspixycat Wisconsin V4 engines don't have a center bearing.
Nice save!👍👍
Well done on the edge of my seat all the way
That's a used crankshaft that's been ground ? I don't think that crankshaft is going to be any good but what do I know
Thanks

@11:56 ... I've been called out before, but not by name! 🤣
Josh, you should have been fine using your steady rest on the main journal, the roller bearing has it's own inner race.
Dear Mr.Topper, it seems at some point in time, you got spooked with auto parts machining. Machining a part is machining a part, auto or not. Hang in there. New viewer, like your videos.
The problem is never the work. It is the customer of engine work. That is why I almost always refer them on to automotive machine shops.
Nice save
just curious why he didn't either get the correct shaft or fix the old one
Old one was bad. Parts are not as available as they used to be. He had this one laying around and had it ground and ready to go. He didn't know the old one was different until he took it apart.
