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.
@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
@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
@chrisc1032 just insert a rag around the connecting rod, sometimes i use a shop vac nozzles to suck out any dirt
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
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.
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.
@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!
@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
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!
Great job on the video! Nice to see something repaired instead of thrown away.
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.
@FunOnTheFarm7 not necessarily but i prefer to, make sure it is rtv silicone
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 :-)
@kimokanka thanks man! i recommend an OEM kit from husqvarna, but u can take a chance with the chinese kit
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
@dosher101 they are both 2 strokes but different engines
you can use a parts washer, i put a rag where the connecting rod is to prevent dirt from getting inside
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
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
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)
that sucker is a hoss! good job db73!!
@lulukelley2004 did you try a new ignition module?
@99carnot yes i use craftsman tools as well
Im not rebuilding a chainsaw, i just like watching videos like this so i will learn more about small engines.
@AttackratUK THANKS man, part 3 tommorrow
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
Excellent video buddy!! Very well explained and good to watch. well done.
Excellent series, well done.
it doesn't take long for compression to build up if all parts are still good
@3wheeler016 thanks for the tip
@donyboy73 Ok, thank you! Do you recommend to use loctite on the cylinder head bolts? if yes Blue or red? or RTV Silicone ?
@azfires000 no videos yet but it the same idea as any other rebuild, be careful with the intake boot
@peebstech good tip!
@azfires000 nice to hear!
Well done donny great job.
thanks for the tip!
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?
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.
hi, I bought a cylinder piston kit on amazon, not original for a jonsered 2159, do you think will fit?
@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
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?
Hey there, thank you for your informative videos! Just wondering how the Chinese made cylinder head worked out? Thank you.
Just curious, what do you use to clean the casing and components ?
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?)
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
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
@FunOnTheFarm7 because the crankcase should be the same
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?
What kind of oil were you using to lube the piston and bearings and stuff?
thank you!
@rtzapper thanks
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 the video, where to buy your short blocks from?
@Cenobita90 thanks
do you flush the crank case with the solvent also once the exterior is clean?
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.
Excellent video I learned alot!
Is there any way to completely remove the whole engine? Including the crank case. Great video.
What is the purpose of mixing the oil and transmission fluid? Thanks for all your help!!
i also use permatex motoseal, better in gas environments
i have a husqvarna rancher 455, can i follow your video for my saw as well??
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,
@Smallgasengine1 i do not believe it is chrome plated,
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.
Great video. Do you have a link to the parts you used? I am trying to be sure I get the correct parts.
welcome!
great video! Very informative
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
@BR4DL3YY it is 55cc
What process did you use to get the case so clean and not get any foreign matter inside of the case?
@sscustoms100 i used corel videostudio
@ncrdisabled just got the new pc last week
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.
@azfires000 it would be better with the head off especially with such an expensive saw
Good video man thumbs up !
thank you
@azfires000 blue loctite and motoseal rtv silicone
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.
i have a 55cc rancher, i need a head as well where did yuo ger your chainsaw head?
thank you
that may have been for the handle or a buffer
@donyboy73 seen one in london, back in 1989, very nice, lol
Good person and good mecanic
@1972FordF150 thanks dude
Hi. I have a husqvarna 55 and i need to replace the piston and liner ,Where do you recommend getting the parts and whats aa good price to pay for them? there are lots of suppliers and prices on the web thanks,
HRose
hey donyboy want programe did you use to add you logo to the video in the bottom corner
NOT YET BUT IF YOU LOOK AT MY OTHER CARB REBUILD VIDS IT WILL BE VERY SIMILAR
@azfires000 good job! i have a pdf parts list if u need one
thanks for watching!
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
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!
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.
will a husky 55 piston and jug fit a husky 50?
