- Chainsaw Top End Rebuild - Husqvarna 345
In this step by step video I show you how to rebuild the "TOP END" by replacing the cylinder piston and ring on a Husqvarna 345 chainsaw. If your chainsaw has no compression it definitely needs a new top-end rebuild!

Easy to follow and thorough step by step tutorials do it yourself (DIY) to help you with your broken lawn and garden equipment including snowblowers.
I do my best to teach you how to easily diagnose problems the fastest, quickest and most efficient way with real repairs beyond just replacing a spark plug. These tips are for both the homeowner and shop owner.
Whether it be a handheld, two stroke, two cycle engine like a chainsaw, weed eater, weed wacker, string trimmer, grass trimmer, line trimmer, hedge trimmer, strimmer, brush cutter, leaf blower, or four stroke, four cycle units like a lawnmower, wood splitter, lawn tractor, snowblower, pressure washer, generator or a ride on mower that needs parts installed or replaced, I’m your go-to guy.
My favorite brands of spark plugs are NGK and Champion and are the ones I recommend.
I’ve been a small engine mechanic for many decades and also run my own repair shop so my videos are loaded with tips and tricks that I have learned and want to share with you. You will also find many tool and product reviews from top brands on my channel as well.
I have the largest Small Engine Repair Video Library on UA-cam and the entire internet with over 1200 videos, just GOOGLE "DONYBOY73"!
I want "DON THE SMALL ENGINE DOCTOR" on UA-cam to save you time, frustration and most importantly, MONEY with my HOW-TO videos!

"It does stink, though" LOL! Donny keeping it real! Stay safe, my brother!
Thanks for no music, no noise and no extra talking. This is how a learning environment should be.
Amen to that!
I agree. I think the music is a distraction. The tone and inflection ove his voice is great for an instructional video.
Absolutely the gold standard for small engine instructional videos - well done, DB!
I run a modest tree service. Ive seen a lot of these vids. This is not my saw. I run much larger saws. But this is the best rebuild video ive ever seen. Thank you.

Thank you, Don! I watched your video and it helped me to replace the piston and cylinder on my Husqvarna 440e x-torq chainsaw. It was a successful tear-down and re-build in large part thanks to your excellent and informative video. Much appreciated!
Thank you so much for all of your videos on rebuilding chainsaws. I have a Husqvarna 261 from 1999 which has performed well over the years but recently I've noticed it has a lack of power. After a compression test I only got 115 PSI. So I bought a top-end rebuild kit off Amazon for $100. The cylinder and piston are from Taiwan. Watching your video and following your instructions I was able to tear down my saw, clean everything in the parts washer, and reassemble the saw with the new cylinder and piston. It looks and runs like a new saw again!! Now I'm getting just over 150 PSI on the compression test. Without your videos I would never have attempted this on my own. THANKS!!
Thank you so much for your great instructional video.
I live in Tasmania, which is a state of Australia.
My Husqvarna 555 required a cylinder/piston rebuild and the local chainsaw repairers were going to charge me around AU$700 to fix.
I was able to purchase genuine OEM parts from the USA and even with our poor currency conversion and freight, I was able to purchase and repair myself for under AU$200.
Of course, I would not have been confident enough to attempt without watching your video and even though it was not specifically my model, it was enough to instruct me to repair.
Thank you, thank you, thank you.
Make sure you are subscribed and greetings from Canada!
Hi Dony,
Great job with this video. Rebuilt my 345 in an afternoon watching this video - so far, runs good. Can't tell you how much I appreciated the expert guidance.
Only trouble I had was with getting the piston to fit in the head; you made it look so easy in the video, but that part took me about 10 tries....LOL.
Thanks again :-)!
I don't even work on small engines a whole lot, but I've long ago forgotten how many times I've seen people buy something *really* expensive, and then run it with no oil.
"I can't be bothered mixing oil into the gas, it's too much trouble! I'm only using it for a weekend, it won't make any difference!"
*engine fails*
"What a piece of crap! They don't make 'em like they used to!!"
Great step by step instructions, and important advice regarding determining failure cause. Awesome parts washer! Nice how easily you installed the cylinder.
Thank You Thank You Thank You!! Excellent video! I just rebuilt the top end on my Husqvarna chainsaw following your instructions and using the replacement parts you recommended and i was able to complete the job in a few hours and the chainsaw is working like new again. The shop wanted $350 plus to fix it and I got it done for $80 myself and had the satisfaction and fun of doing it. I couldnt have done it without your help so much appreciated! Cheers donyboy
Great video, Nice, slow , methodical and to the point. Just rebuilt my Husky 345 and it worked. Then I used the same video as a guide to replace the piston and cylinder on a 346 XP and now it works great.
This video allowed me to do my own repair. Saved me hundreds over a new saw! Thank you!
Thanks so much Don. I just rebuilt my Husqvarna 340 per your video. It's now as good as it was the day I bought it. Your video was just perfect. Keep up the great work!
Hello Don,
I have the Husqvarna 345 chainsaw and have been using it for 6 or 7 years. The 345 is a real performer and whether I use it for 2 hours or 8 hours it's never failed to impress me.
I enjoy your videos a great deal. I like the way you explain everything clearly and using your videos as a complete guide have been a great learning tool saving me quite a bit of hard earned money.
Thank you and keep up the great work!
Regards,
Bob
I recently trying to start my own chainsaw repairs because I love chainsaws. I bought a stihl 021 and I’ve been looking at video repairs for a few tips. I went to a saw shop 26mins away and said it would cost 600 to repair it so I bought the aftermarket parts for it. I already took it apart to see what was wrong and I’m ready to repair it and I thank you the most for these tips thanks.
I had the same problem on a similar saw (353); this video made my life SO easy! Thanks!
love your work don you make it look easy step by step
you are one of my real life heroes. I really mean that. You put a lot of time into this. You are a giver. May God bless you for all that you are. Thank you
Great video Donny, details are great! Always good for a refresher. Can never have too much knowledge. Always watch commercials to the end, no matter how long they are, helps his AWESOME channel!
You are a great teacher! Forever grateful!
Great instructional video
No waffling. Thank you
Thank you for this detailed video, and followed step by step and it worked out great -I'm off to the woodpile.
You hands down have the best tutorials for fixing saws. Your attention to detail in explaining every little thing is exceptional and the clarity of your camera angles is excellent! Thank you for your time and dedication to your videos.
Just 2 questions, and i apologize if you have already answered these, what type of oil do you apply on the piston? And is that redish color stuff you used (i cant recall the name you said) on the base of the cylinder head, like a form of gasket maker?
From an old saw tech- Excellent video!
You make it look so easy. I always forget what screw go where and how I got it all apart.
Nice job.
The piston kit with cylinder and carburetor kit for Husqvarna 235 just came in
😁
I’ll need to psych myself up to fix my 235
Nice work! Thanks very much for the instructions.
All the best.
After being quoted around $600AU I decided to pay $150 for a new oil casing & muffler & try and do the repairs myself. I spent many hrs watching videos but still didn't feel that confident until I came across your videos. Now I think I can do it, thankyou.
Fantastic close up photography, well done and thanks
Thank you for the video. I just did this on a husky 350 I got from my dad. Excellent video. Runs like a top now thanks to you.
I have a saw just like that had it for a lot of years great saw. Done a great job on the video my friend. Never seen one rebuild before. You my friend are a master at that great job
Your videos are top notch, good explanations and you stay calm and do a nice job
very detailed...i'm glad i discovered your channel...
Hey Don; It was deja vu this morning as I checked out your weekly video. I am just installing an aftermarket kit on a Husqvarna 359 that I picked up from another supplier. This was my first time using an aftermarket kit as the retail cost on the OEM kit was $389.00. My concern was the very rough chamfer on the edges of the ports. I cleaned them up with some emery cloth and feel better about them now. I was suitably impressed with the clearances and the quality of the nikasil, but I guess time will tell. Thanks for the video as it is clear and concise as usual.
Excellent VIDEO. Thank you.
Thank you for your instructions,and not talking,about a certain part to long...You,are a GREAT Teacher..God Bless
Nice job! And very informative and helpful video! Job well done, as always!
thank you sir i did most likely everything you did in this video to my husqvarna 340 and its runs great now.couple problems every now and then but it was my father old saw and he didnt took care of it
Thank you I just fix a chainsaw the somebody throw away I put a stud for the chain new gas lines new bar and chain now runs like brand new I have learn a lot from your videos thank you again
I really believe this Man could do this in his sleep! Huge thumbs up, and thanks for all your great content. It really helps us dummies, like myself! 😀 Peace! 👍👍👍
Excellent video wish I had watched it a few weeks ago was working on two husky 350's....
Excellent video, thorough & to the point! Thank you for that! Now I'll try my hand at it on a Husqvarna 42 special..
Dony, what a fantastic vid. Your expertise is very evident; great step-by-step repair with lots of detail and excellent photography. Thank you. Keepwell
Love your work. Very easy to follow. Thanks
Thanks Don, just ready to start the same on a 350. Off I go. Thanks so much for the excellent video.
These are GREAT video's Don...very detailed...thank you.
Excellent video; did cylinder & piston on Mac 335 using this guide. Tips: put the gudgeon pin in the freezer and warm the piston (I put it a jar in some hot water) then the pin can be pushed all the way in with your little finger; grease on the rings will keep them in the right place as the piston is pushed into the cylinder (the new cylinder was coned so did not have to squeeze rings).
thank you so much for a helpful video and information you provide to us viewers ....
Hey dony
Thanks a lot for your very detailed videos they are great ,truly amazing,
I live in Ireland and I like to fix machines specially small engine machines for my friends,
I think you’re videos are brilliant
And you are definitely an inspiration
Thank you for all you’re effort
Nicely done brilliant
Best of luck
Thank You donyboy! Great video! just rebuilt my 385xp and it runs great! I hope
discountonlineparts know how much business you send them!! YOUR THE MAN!!
+Eric Pollard thanks
This is superb instruction. Thank you.
I've been told that the plastic intake clamp band is prone to fail in 300 series saws, and they'll overheat. I discovered mine is loose so I'm going to replace with metal
Exellent job! This chocke plastic lever looks brithle maybe I m wrong. Thanks for sharing.
Fantastic presentation!! Thanks!
...Great video!...I'll add...whenever I rebuild a 340 or 345, I always upgrade to the 350-type top end...you can get the China aftermarket piston/cylinder kits, often with the 350-type adapter block/bearing holder included, for just about the same money you pay for the 340/345 one-piece kits, especially if you buy the open-port 49cc kits...then you have a stronger bottom end, the customer is happy about the extra power, and the rebuild is easier due to not having to deal with the pain in the b*tt job of getting the piston and rings started into the bottom of that one-piece job... with wet sealant getting everywhere while you are trying to get it started :(...with the 350 style setup, you can assemble the bottom end, then let the sealant cure, then install the cylinder... :)
Dony thank you for all your great videos. They have helped me numerous times.
Should have used a bearing block from the Husqvarna 350 and a piston and jug ignition coil from a 346xp. It's a bolt together mod and makes a light weight homeowner saw run as well as a 50cc professional saw.
A hose clamp makes a good ring compressor.
Well Donny boy
I finish my rebuilt on a husqvarna 235e
Found an original Husqvarna piston n cylinder kit on amazon for $14
Cheaper than Chinese parts
Took me 2 hours to do it
It work like a charm now
Thanks
actually the 235 is a poulan . maybe thats why it was 14 bucks
That was so simple, Thanks for an awesome video. Very helpful.
This is one of the best videos I've seen you put out donyboy. It's a beautiful job and I really appreciate you sharing this. I'm not likely to ever do this myself but it gives me an insight and appreciation of what goes on in your business. Let's say it's been iluminating. You mentioned a fuel mix of 45:1 there, might be a pro model. My Husky uses a fuel mix of 33:1 and it has given me nearly 4 years of service, and now I'm at the end of the second chain. It simply keeps going if you look after it and follow the manual.
+Gregorynts thanks!
best howto video on youtube, thx
Thanks for your videos. Its so useful.
great rebuild video--well edited--thanks
Great Video Don ! Thanks for sharing
New to your channel. Excellent editing and concise explanations. Time well spent for me. Your efforts are apparent.
That was an excellent presentation, very well done.
great video dony I learn so much from you thanks
As usual awesome videos and instructions
I have two saws to rebuild just like this love this video next payday I’m ordering the kits I need
Good job Dony it looks like a new saw thanks for the vid. Regards JohnKinnane
Very well done video - and I used to write tech manuals and do tech videos for a living - and (I think) this vid could be used as a "how to" for making such videos.
Very helpful video. Thank you!
Awesome vid, you're the best. Thx
I like your torx and and allen key bits, i just got the L shaped ones
So looks like i my be wrong!
I may be wrong about this also, "those two parts do not get installed WITH THAT KIT at all"
But I am very thankful for the very well put together video and you do nice clean work.
Next time you get one of those kits look at what I thinking.
Thanks again!
Another really well done video with excellent lighting and camera work. Easy to see. Easy to follow. Thorough explanation with helpful troubleshooting tips. Your videos are top notch.
+mybigtokachi thanks!
Good for you Joel!!!
Nice job Dony. Top quality production from top to bottom, front to back.

Beautifully done Don 👍🏼
Thanks for your video !!!
Encore une excellente vidéo å tous points de vue (information complėte et qualité de l'image exceptionnelle). Merci !
dony, you are awesome sir, i salute you. love all your vids
Really nice job man .. I would like to mention that if most of the substandard finish work with the new barrel is a problem for you theres alot of improvement to be had in the use of a die grinder and a cartridge roll for finishing .. even the stock barrel had about 1/8 inch of material that could have been port matched on the exhaust side.. there is tons of power to be gained from a bit of smoothing of the ports .. I wont get into changing transfer port height or size as a means to make power .. but you could improve the saws power 25 percent or more from port matching and smoothing .. love your channel nice job
wow soooo much easier to deal with the piston clip than the stihl one that i just watched, same (similar) top end rebuild but didnt have the bent in section on the clips, just a little groove for your pliers nose lol
I was looking at specs and comparing this Husq vs a Stihl 250. Putting a top end on that with the little fiddly bits looks like a real chore and potential swear fest for me. Was hoping it would be easier to rebuild than a MS250 but sure doesn't look like it. Guess I'll stick with what I got. Thanks for the vid!
Awesome
Now I’m going take apart my Husqvarna 235 that has a score ring
I’m pretty sure I’m going to end up with a chainsaw that I cannot put together
But hey
This video gave me the confidence
🤣🤣🤣🤣
Wish me luck
i did a 235 and it was pretty easy .
Fantastic video! Thanks for posting.
Question: When reassembling after cleaning, should we place some oil in the lower crankcase ? (if so, how much are we talking and which viscosity of oil?)
Great video! Nice step by step...
Wow, you have no idea how much time and worry you saved me by describing the small plastic piece at the back of the throttle linkage (at 4:40 in the video). That exact thing happened to me!
As usual, you have done an excellent job. I enjoy watching your videos, as you are a professional.
thanks Todd
I really envoy your diy vids. I find them very helpful.
+Sean Carver thanks
thanks for another great video. how do you properly tune the top end on a rev limited saw
I have a 345. Best saw I've owned.
Excellent Video... Thank you. I will have no problem putting my 345 together again. :)
Best channel on UA-cam.
as always excellent don , thanx for the lesson
thanks for watching
Great video Dony easy to follow love your work
+tim collins thanks tim
congratulations again because you are still good at repairing chainsaws :)
Your video helped a novice mechanic replace the cylinder and piston on an old popular p3314 chainsaw. I finally got it to run but seems to be running to hot and smoking quite a bit. I have adjusted both L & H according to your videos. It seems to be running fine and only issue is a very dull chain. Just appears to be to hot. Any advice for a rocky? Your a great teacher in the videos your produce. Thanks for the info you put out.
Man, what a sensational video. Thanks. Thanks also for not playing stupid music in the background.
Super boulot bien expliqué merci j ai la même réparation a effectuer bonne continuation
