Four years ago I was watching this video and realized you were rebuilding a chainsaw exactly like mine. I could not believe that my piston looked as bad as yours but I was so wrong. I rebuilt the whole thing watching your videos- carburetor included - and everything came together like clockwork. I depend on that saw and since the rebuild, it has never let me down. Thanks very much!
what kit did you use?
@@donyboy73 I followed your advice and ordered the parts from China. I think the name of the company was "Farmer Tech" which I thought was a weird name, but whatever. I enjoy your videos. Whenever I run into small engine issue, I keep coming back. Thanks!
pro trick : watch movies at kaldrostream. Me and my gf have been using it for watching loads of movies during the lockdown.
@Kaleb Forrest yup, have been watching on kaldroStream for since november myself =)
Donny, I'm really glad this video was still up. Seven years ago I rebuilt my 55 watching you, and last fall I just knew it was time to do it again. It's been my go-to saw, and with a new top end and carb, I'm sure it will stay that way. Thanks!
I'm 15 and I live on a farm we sell fire wood and I have an air injector 55 and rebuilt the motor with the help of you thanks a lot we saved a lot of money
I'm impressed, I wish all young kids would work hard like you. I can't seem to get my 16 year old stepson to do anything. We have 2.5 ac acres with a majority of the property covered with oak and madrone trees, I give my stepson lots of chores to do but he doesn't want to do much , I even pay him good money.
Just rebuilt my old chainsaw following your 3 parts videos, everything when ok ... explanation and video is so clear, it was easy to follow .... thank you ..
This guy is pretty good!! He has good videos.
Thanks for these videos, i have an old husky 55 air injection that was my grandpas. Been giving me all kinds of trouble. A rebuild is in order. These videos will help immensly!
Thank you Donny! You Are my go to guy on small engine repair instruction.
great video. my 55 just blew the top end after 20yrs use. your video plus a new kit saved me buying a new saw!
+Jonathan Lee thanks for watching
I've always used Loctite when building saws b/c of vibration. Also a stickler on proper torque specs. Good video, straight to the point.
Just a quick tip from a machinist who has to use allen wrenches daily. Sometimes when we get a bolt thats tight or in an awkward place, well get a small metal tube and put it on the short end of the wrench and this way you get lots of leverage and it might be a bit easier than a pair of pliers. But your method obviously works too! I like the videos.
@donyboy73 I really didnt know if I was gonna end with some few extra bolts... but I manage to get a diagram of the parts from a website. the Intake booth was a little pain .... but we made it, and I was so happy!! Thank you for the awesome videos donyboy!
@acscolo how are you? i cleaned it with my air compressor and some gas, i'm hoping to get a proper parts washer this summer, take care
I like your videos, very informative and detailful!
I have a 30 year old homelite bandit chainsaw engine and I am also rebuilding it. It is the first engine I have rebuilt and I am so excited!
I am not mechanically inclined, but its a very nice experience hearing you explain things in detail. Small engine repair is very costly and yet can be very simple. Keep up the good work.
Great job on the video! Nice to see something repaired instead of thrown away.
@chrisc1032 just insert a rag around the connecting rod, sometimes i use a shop vac nozzles to suck out any dirt
Hi Dony,
Very informative as usual. Would like to have seen how you cleaned the saw so well, especially how you kept the crankcase clean
Hi Dony
Been waiting for this vid for a while, nicely done with great editing, not too much watching screws being undone all the way!
Lookin forward to pt 3 :-)
that sucker is a hoss! good job db73!!
Thanks for putting this out there! I also used a chinese top end & thanks to your videos, it now runs like a top. Much appreciated!
you're welcome
donyboy73
hi. if the cilinder doesnt have a gasket at all, i just have to smear a bit of silicone on it with my finger and it will seal the thing?:o (i have another model)
Excellent series, well done.
@spelunkerd yesw the pin is to stop the ring from rotating, it is on most 2 stroke engines and you won't find it on 4 cycle engines
Thanks so much, I really appreciate the time and knowledge you have put into your channel. Add a new subscriber!
great video plus your explanation is excellent, I enjoy watching your small engine videos. Thanks
@kimokanka thanks man! i recommend an OEM kit from husqvarna, but u can take a chance with the chinese kit
Donyboy, I rebuild it and it fired right up!!! i follow all the tip like in the video! thanks for all the help and awesome videos! i hope that will do the job falling some tress!! hehehe
Well done donny great job.
thanks for the tip!
@lulukelley2004 did you try a new ignition module?
i used gas and a paintbrush, i just stick a rag in the case to prevent dirt from going in. then u can vaccuum out any dirt if some got in
@FunOnTheFarm7 not necessarily but i prefer to, make sure it is rtv silicone
@azfires000 I USED GAS AND A PAINT BRUSH IN A CONTAINER OUTSIDE AWAY FROM ANY SPARKS OR FIRE HAZARDS, if dirt fell in the crank case i would vacuum it out with a shop vac
Excellent video buddy!! Very well explained and good to watch. well done.
Makes it look easy as pie, I've never been able to install a piston and rings like that. I've always had to use a ring compression tool.
Excellent video I learned alot!
you can use a parts washer, i put a rag where the connecting rod is to prevent dirt from getting inside
thank you!
Im not rebuilding a chainsaw, i just like watching videos like this so i will learn more about small engines.
@peebstech good tip!
@dosher101 they are both 2 strokes but different engines
Hello, really nice videos, im an engine tuner (2-4 strokes) and,
you should put the wrist pin clip at either 12 or 6 o clock, if 3 or 9, they can snap off their groove because of the piston acceleration, especially on high speed engines ;-)
thanks for watching!
great video! Very informative
@AttackratUK THANKS man, part 3 tommorrow
Good video man thumbs up !
Could you explain on a video some time how decompressor work? I understand what they are used for, I just don't know what causes them to open and close at the proper time.
Thanks for these wonderful videos.
@donyboy73 Ok, thank you! Do you recommend to use loctite on the cylinder head bolts? if yes Blue or red? or RTV Silicone ?
@3wheeler016 thanks for the tip
The high def at full screen if excellent I could see every scratch on the parts and main unit . glad you got a better computer to do the high def as it is a whole lot better not that your other videos were bad those were excellent too.
Hey there, thank you for your informative videos! Just wondering how the Chinese made cylinder head worked out? Thank you.
it doesn't take long for compression to build up if all parts are still good
hi, I bought a cylinder piston kit on amazon, not original for a jonsered 2159, do you think will fit?
Good person and good mecanic
thank for the info I have a 455 rancher less then 20hr on it .loss compression .pistion look good throw exhaust. should i still change top end and piston ? what would be part # and where to get chines parts
@donyboy73 what did you use to clean it before it was all dirty, and how did you manage to not get any dirt/dust get in the crankcase when you were cleaning and such
Super excellent video as usual. You cleaned up the saw great it looks brand new. What a difference from the previous video. Do you have a parts washer?
@donyboy73 seen one in london, back in 1989, very nice, lol
thank you
When you put the piston into the cylinder, you pointed out a little pin that you lined the gap of the ring with. Does that pin hold the ring in place so it can't rotate? I've never seen such a pin in auto engines. Is that little pin unique to this kind of engine?
@99carnot yes i use craftsman tools as well
Is there any way to completely remove the whole engine? Including the crank case. Great video.
Why??? Why i didn't saw you video some days ago.... I have a 2 strokes engine with two cylinders and for some reason one of them always have low compression, after days of thinking and replacing the rings I thought that the exhaust port can be damaging them. Now I found your video and you confirm my suspicions, now i need to wait for the new rings. thanks for your video.
Excellent tutorial. I am overhauling a Husqvarna hedge cutter. Failed to start after loaning it out - I suspect incorrect fuel/oil mix might have caused damage to piston / rings. I have overhaled the carb but still wont start. Is the cause now likely to be piston or ring damage caused by possible overheating? Watching your vid now has given me confidence to dissasemble or can I check compression first (if so how is this best done?)
Just curious, what do you use to clean the casing and components ?
What is the purpose of mixing the oil and transmission fluid? Thanks for all your help!!
@azfires000 no videos yet but it the same idea as any other rebuild, be careful with the intake boot
This video series is great. My only question is the original cylinder on my 51 did not have a port for the decompression valve and the new cylinder does. Do I simply cap it ?
yes just cap it, you can buy the caps on ebay
Great videos , thanks for posting. I just seized my husqvarna 365 today. Not sure what happened yet, haven't taken it apart yet. What supplier on eBay did you use? I saw a couple different ones and how has the saw you rebuilt held up with non- oem parts?
do you flush the crank case with the solvent also once the exterior is clean?
nice job!
Thats what i been looking for, a step by step process of the re-built. I dont wanna do it but...
My question is, I have a 575 XP Husqvarna chain saw. I need to retap the spark plug. I never done it before so Im nervous about it. Do you recomend to remove the head or do it on place? Im just worry about the shavings of the retap.
Thank you
Dan
@azfires000 nice to hear!
thanks for the video, where to buy your short blocks from?
What kind of oil were you using to lube the piston and bearings and stuff?
hey donyboy want programe did you use to add you logo to the video in the bottom corner
i have a 55cc rancher, i need a head as well where did yuo ger your chainsaw head?
thank you
very heplfull video,thankz
welcome!
i have a husqvarna rancher 455, can i follow your video for my saw as well??
awesome video
@rtzapper thanks
i also use permatex motoseal, better in gas environments
These videos were great. I did something I never thought I could do. However.. I reassembled. Got compression. Got spark. Cranked for a second with starter spray in carburetor. I tried bleeding the fuel line. I had soaked the carburetor but no maintenance. Can I assume it's the carburetor? An idea for you is to review these rebuild kits!
What process did you use to get the case so clean and not get any foreign matter inside of the case?
thanks for the info
I need to do a top end rebuild on a stihl fs 80 is it about the same like you did on the 55 Husqvarna if you can lmn i can not find a video on it no where
where can i find a piston ring for a husqvarna 155bt backpack blower besides ebay?
@azfires000 it would be better with the head off especially with such an expensive saw
@FunOnTheFarm7 because the crankcase should be the same
@donyboy73 Thank you.
NOT YET BUT IF YOU LOOK AT MY OTHER CARB REBUILD VIDS IT WILL BE VERY SIMILAR
Is there any kind of shim that under the cylinder sits in front of the casing ? Seems gas is coming out down by under carb.
the problem in your case is that the cylinder piston and rings all need to be replaced at the same time to have optimum compression,
@1972FordF150 thanks dude
Great video. Do you have a link to the parts you used? I am trying to be sure I get the correct parts.
will a husky 55 piston and jug fit a husky 50?
@azfires000 good job! i have a pdf parts list if u need one
Hello I have a question, I am currently working on a 33cc 2 stroke engine for a scooter. My piston is all scratched from the carbon build up and I am going to replace it but are there other parts inside the engine that can get damaged because of the piston ? Thank you.
what kind of oil do you use in your oil can to lubricate the piston and cylinder? It looks red.
@Cenobita90 thanks
