Chainsaw Top End Rebuild - Husqvarna 345

[@dwaynemadsen964]

"It does stink, though" LOL! Donny keeping it real! Stay safe, my brother!

[@SA-lr1sf]

Thanks for no music, no noise and no extra talking. This is how a learning environment should be.

[@georgedavall9449]

Amen to that!

[@Goodellsam]

I agree. I think the music is a distraction. The tone and inflection ove his voice is great for an instructional video.

[@mikerush9283]

Absolutely the gold standard for small engine instructional videos - well done, DB!

[@peterluscher1410]

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!

[@arborymastersllc.9368]

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. Ethan

[@crebbull]

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.

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!!

[@lazaruslong1971]

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

[@SimpleLife1971]

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

[@craytopia]

This video allowed me to do my own repair. Saved me hundreds over a new saw! Thank you!

[@anthonyleighton9223]

Thank you for your instructions,and not talking,about a certain part to long...You,are a GREAT Teacher..God Bless

[@bretthollyeslick2767]

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!

[@robynmiles6344]

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.

[@jayrmalcolm]

I had the same problem on a similar saw (353); this video made my life SO easy! Thanks!

[@Wiskys]

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?

[@toddschick]

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 :-)!

[@austinmichael406]

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.

[@georgedavall9449]

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! 👍👍👍

[@boristrgovcich2171]

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.

[@norcoauctions]

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

[@JamesFPV]

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.

[@arnenelson4495]

From an old saw tech- Excellent video!

[@scottsmith507]

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!

[@sofjanmustopoh7232]

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

[@99carnot]

Great step by step instructions, and important advice regarding determining failure cause. Awesome parts washer! Nice how easily you installed the cylinder.

[@outboardfixer]

These are GREAT video's Don...very detailed...thank you.

[@sofjanmustopoh7232]

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

[@jameslee2105]

actually the 235 is a poulan . maybe thats why it was 14 bucks

[@dyer2cycle]

...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... :)

[@bjnopoli]

I have a 345. Best saw I've owned.

[@devilsoffspring5519]

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!!"

[@tyroneclarke1666]

Hi Don. I’ve watched this video before. Second time was just as good. I like your attention to detail and care you put into your work. Explaining as you go step by step is clear and precise too. Lovin the parts washer hehe. That is a must for your repair shop. Stay safe. Regards from Perth Western Australia 🦘🇦🇺

[@erlinmyer4185]

Best channel on KZbin.

[@markproulx1472]

Man, what a sensational video. Thanks. Thanks also for not playing stupid music in the background.

[@5adamjb]

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

[@cliffordmacdonald4748]

[@lesliewatts2878]

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

[@timlewis8231]

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).

[@Geob55]

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.

[@roncoleman9502]

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

[@GaryWRose]

best howto video on youtube, thx

[@rogerbenton2354]

I have a 340 which belongs to my wife’s uncle. It is really loose in the frame. You can grab the bar and it will move a half inch like something isn’t in place or broken. I wonder if you have ever run in to this before. I love the videos and the time you put into them. Thank you

[@billarenz2719]

hey Donny, thanks for another awesome video on how to properly remove a clutch on a chain saw without causing damage to it.!!!

[@Smoothboxnailer]

Excellent video, thorough & to the point! Thank you for that! Now I'll try my hand at it on a Husqvarna 42 special..

[@hommyy-c5494]

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

[@jtd4847]

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.

[@Certainly-somebody]

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

[@francescomereu682]

congratulations again because you are still good at repairing chainsaws :)

[@joncanary4778]

Thanks Don, just ready to start the same on a 350. Off I go. Thanks so much for the excellent video.

[@Gregorynts]

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.

[@donyboy73]

+Gregorynts thanks!

[@brettgallagher259]

Beautifully done Don 👍🏼

[@lukep6017]

Excellent VIDEO. Thank you.

[@kent7927]

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!

[@paulworkman5755]

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.

[@scottfirman]

I spent a lot of days replacing cylinder heads on snowmobiles. I remember polishing and porting every one of them. It was important so the rings wouldnt catch on the port and destroy everything. I bought a friends snowmobile where he just replaced the head but forgot to chamfer the port and the rings broke. He was nice enough to replace everything. I spent a few hours polishing and porting. I had a book specifically on how to do this. An old timer gave it to me when he had a speed shop. It was invaluable.

[@andrewlara7992]

If you don't mind me asking, what was the title of the book and who was the author? I'm just starting to repair these systems, and I really want the insight.

[@scottfirman]

@@andrewlara7992 sadly I do not have that book any longer as I believe I sold it. I am still kicking myself. It is no longer available anywhere and I couldn't tell you who even produced it. As we switch over to computers and electronic information, we are losing many of these rare gems. That book made me better in terms I cannot even describe because the knowledge it contained is no longer available.

[@FritzMadness]

I like your torx and and allen key bits, i just got the L shaped ones

[@fingers967]

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

[@Marcel-Namsos]

Excellent Video... Thank you. I will have no problem putting my 345 together again. :)

[@mototally3514]

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!

[@sofjanmustopoh7232]

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

Darn! After watching this, I want to buy a workbench and fix my Husq Rancher!

[@557ronb9]

I sent my 345 to get fixed at a small engine repair shop....would not stay running and for the kill switch that did not shut off. After spending $123.00 and leaving my saw there for over a week the first time and another 3 days the second time. I got it back and the switch had butt connectors on it and still doesn't work and they said they rebuilt the carb and it was doing the same thing as before " would not stay running. So now I will fix it myself now that I have time. Thanks for the info and the link.

[@eliasvillatoro6224]

Thank very much great video

[@ralphsmithco1]

New to your channel. Excellent editing and concise explanations. Time well spent for me. Your efforts are apparent.

[@kevind3185]

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.

[@aeridyne]

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!

[@robertshoemaker6204]

Excellent video wish I had watched it a few weeks ago was working on two husky 350's....

[@brucel.6078]

Fantastic presentation!! Thanks!

[@PaulBenedict1]

Hello Donyboy73, forgive me if I am mistaken, but at 20:25 of the video, after slipping the throttle linkage into the carb arm, you should have slipped the retainer spring end under the tab to prevent the linkage from coming out of place. Anyway, good job on the rebuild.

[@MrKakuaa]

Awesome work ethics plus managing recording and whole lot. Very impressed. Definitely you are a bucket fillers not a bucket dippers personality.

[@donyboy73]

[@canadian_wolf8395]

I have an old saw that I found in a shed and it needs a carb clean but the saw itself is filthy so while I have the carb off could I still wash that saw with a parts washer as long as I dry out the cylinder?
