About to dive into a couple STIHL 362 rebuilds. Help!

[T.Bird]

Greetings! I snoop around here every once and a while when I’m looking for answers to various questions that arise in my work as a production arborist. You guys are great! So here I am… finally making an appearance as a registered user and begging for your help:

There are these two Stihl 362s with bad motors just collecting dust in our shop. I am not entirely sure what is wrong with them yet, but my boss claims that the pistons/rings/sleeves are bad. He has purchased the necessary engine rebuild parts for them and had told me that if I manage to successfully get them running again, he would give me one of them. Sounds like a good deal to me! Actually, it sounds like it could be a lot of fun! I like to think that I am pretty mechanically inclined and I have a LITTLE bit of two-stroke engine repair experience, but this would pretty much be a new venture into uncharted territory for me.

I am starting my journey here hoping you folks could provide me with some advice, guidance, encouragement, love, support, and maybe point me towards any available resources out there that might help me with the project. Thanks!

These might help, just take your time and do it right or you might end up breaking something. I did a crank replacement last year on one of these and it wasn’t that bad, hardest part was trying to get the wiring seaport without breaking the little connectors lol.

And make sure you find the reason they broke in the first place or it might be for nothing if they just break again.

if you decide to give up or turn down that offer to rebuild i'd do it for him for that offer

FWIW, I found that a complete top end rebuild of a Stihl 362c was much easier than the 441c I struggled to save. Rebuilding the 441c was an abomination by comparison. I was successful in both cases but I doubt I would ever again rebuild a 441c M-tronic.

What you will probably find is that the piston rings are gummed up in the piston, I have had a lot of these saws with this problem!

They’re not that bad! Did a couple of those, one being a 441 M-tronic Arctic and this one was a bit challenging but still worth it.

Have a 362 under the shelve as well so I’ll be interested to see how this goes. Please post some pics when you go along.

Also, don’t just slam on new parts, look for the fault first. Could just be faulty wiring, those 362s are known for that.

I'll keep you in mind.

That's reassuring. Thanks!

Yeah... good point. Honestly, I am now getting a little more intimidated by the diagnostic project that I suddenly have in front of me then that actual repair work itself. Troubleshooting is hard!

No need to be intimidated, it's not rocket science just need the proper tools. Here's the service manual, it has every step detailed

You wouldn't happen to have a service manual for a MS362CM?

Thanks!

No, sorry, but you maybe you can ask user Ray Benson over on "the other site"

I'd stay clear of this rebuilding crap. Not unless you are willing to go to far greater lengths then you might expect. Unless you know the history of the saw, there can be costly discoveries along the way. To many people abuse their saws, and aren't even aware of it. And even if aware might not share all the information that might help you. Screw it. Let them rebuild it themselves.

pull the clutch drums and look at the crank before ordering a single part. 261 and 362s are known for wearing the crank where the clutch drum bearing rides

 

[Vintage Engine Repairs]

Who’s paying for parts? You may find that may cost more than the cost of a new saw! Best of luck though and lots of us are willing to share what we have learnt in our journeys

I REALLY hate to ask but.... do you know what type of gas and mix oil was used in these saws?
And getting a free 362 for rebuilding 2 is a fantastic opportunity.
