Can’t believe I’m found this channel so late! This is gold. Thanks for sharing mate, some great tips here
Thanks Mike, I appreciate the kind words and I’m glad you enjoyed the video!
Mattyo's crank tool makes jobs like this so quick and easy, so worth the investment. Good series of videos on the rebuild, job well done.
Hello
Great help! I too have watched hours of Matt Olsen DDS. I’m going to make the instal tool as well. I’m rebuilding a Husky 359 which is my first. It is IMO a great firewood saw. Appreciate your videos. Bud G from Nebraska USA.
Glad you liked it and best of luck :) warm regards from Australia!
Great video. I’ve found sockets can be used to press bearings in. Key is to make sure the socket is on the outer racer, otherwise, you’ll trash the bearing.
When you heat the case, does the bearing literally fall into the crank housing without any pressure?
Awesome, yep I like using sockets sometimes too! Yes the hearing will literally just fall out when the case it how enough. Just note, when you heat it up over 10-15 mins in the oven, the powdercoat will start to yellow, that’s why now I only ever use a torch and do a quick burst of heat. Hope this helps!
@@VintageEngineRepairs Thanks, that’s really helpful. Do you have any tips with how I deal with the wrath from my wife regarding using the oven to heat engine parts? 😂
Nope, other than do it when she’s not there and allow yourself an hour or two to air out the house after of the burnt oil 🤣🤣🤣 good luck! If I don’t hear from you, I’ll know why!

Great explanation! Top notch work!
What to do when crank spins with resistance bit more than you would expect from two bearings (no seals installed)? How to know where to tap/pull/whack?
@@VintageEngineRepairs Thanks. It worked, kinda. It spins more freely. Wish it would spin even freer though. Hard to know how free it could possible spin. I'm ready to let the running engine sort the rest out. Surely heat and revvs from saw running could relieve any last preload?
@@VintageEngineRepairs I used heat on case and bearings on both sides plopped down in the pockets good. I heated center of bearings in the case on clutch side and crankshaft dropped in place good. On the other side it did not drop all the way as me fiddling with the gasket made bearing cool and I used the bolts on the crankcase to close the last 3mm. Guess the preload comes from that? I have no tool to pull the crankshaft. Would such a tool and to give the crank a pull relieve preload?
Hi,can you give us a link with the tools that you use..thank you😊
These are custom made, you need to reach out to matty-o on the OPE forum :)
Doesnt putting oil on the crank shaft make an unnecesary layer of material between the bearring and shaft which is also a slippery one in a place where you want them to stick
I always do so both as it is per the oem instructions and for ease of installation and to stop galling / damage. 👍🏻
@@VintageEngineRepairs just to be sure, thats 2 stroke oil were talking about?
One more thing, ill be building the bottom end of a chainsaw(ms360) for the first time, so i dont have the crankcase build tool like you used to put the crankshaft into the case halves. Would it be fine if i inserted the bearings into the case first, then put the crank shaft into a freezer and before assembling also heated up the case halves with the bearrings in them. Would that work? If so, any tips?
Yes you can do, just don’t overheat the bearing. It’s very likely it will get stuck half way too and you’ll end up forcing the bearing on which will side load the bearings. Not ideal, but some people do!
@@VintageEngineRepairs sounds like thats a high chance to waste 42 euros worth of bearings this way. How else could i do it without the tool that you used?
@@karm00n29 I wouldn’t really recommend any other way. Installing the bearings onto the crank first can be done, but you still open yourself up to issues. Give it a go; just don’t overheat the bearings. If in doubt, see if your local shop has a puller?
What seal setting tool are you using?
It’s an oem seal driver!
The thanks thing didnt work. So i have to give you a big hug and kiss-
Hahaha all good 🤣👍
Bagus guys,saya suka video kamu👍
Thank you!
What about the crank bushing, is it replaceable?
Bushing? There aren’t bushings in this crank!
@@VintageEngineRepairs I meant needle crank bearing :V
Gotcha :) the big end on this and most models isn’t, on some models it is though!
why does no one replace the big end bearing in a saw when they do it in dirtbikes and race carts
You can't replace it. Need a new crank when big end bearing is gone... Expensive OEM part
New sub, best wishes
Hiányzik a Magyar felirat!
Thanks for the feedback!
Freeze the bearing
Yep
The silicone is absolutely unnecessary on the gasket AND seals all it does is make it look sloppy and unprofessional. None of the manufacturers use silicone at all. It's wasting time and silicone. I've been doing this for 40 years and advise AGAINST the use of silicone on the crankcase and seals
Unless you have crank case seal issues do not use gasket material just a gasket
Thanks for your comment Len though I disagree. Brand new from the factory, all surfaces are perfectly machined. Over the years and with careless mechanics, the surfaces get damaged and the surfaces are no longer machined, this isn’t silicone just so you know, it’s a purpose made aviation gasket dressing compound.
