Stihl 064 rebuild questions

[Arcticmiller]

Hey folks,

Financially this probably doesn’t make sense- I get that.

My dad gave me his old logging saw a decade ago, an old stihl 064 full wrap. It kept food on the table when I was a kid while he was a logger, and after that served firewood duty for nearly 20 years until ethanol did its dastardly work. Rotted out the carb, and the tank drained into the bottom end somehow and with its special moisture gathering properties. It took out the bottom end bearings, froze the ring on the piston, and spread varnish everywhere-nasty cleanup.

Anyway the jug and piston were in ok shape, but if I’m going to do a total rebuild how are the aftermarket top ends for the 064’s? I know some of them aren’t good performing. I may just find a new old stock top end.

The crank was actually in solid shape last I checked-it seems like the nasty stuff pooled up like it was stored on its side or something.

Anyway it’ll be a sentimental build that I can pull out and make a few cuts with from time to time.

Finally getting to it!

Stick with OEM for your top end.

If you want info about AM top ends, it probably will be mostly all negative.

If you want help rebuilding your 064 , then ask as many questions as you like. @redline4 did a lovely 064 rebuild thread recently. I think it was called ugly 064 or something

Edit: this thread.

Ugly Stihl 064 overhaul

It seems my 064 decided to stop oiling the bar. It still oils the bench, the shelf it sits on, the back of my truck or the bucket of my skidsteer from the case half gasket. So, I've decided to give it a full tear down. This will be in real time. It's deer season and im also working on an engine...

Awesome, I will be looking that over closely. Thanks! I wasn’t set on an aftermarket top end, but I had heard they were alright on the smaller saws, but lacking on the 064-066 sized saws.

Unless the plating is worn through, I'd be willing to bet the original jug can be used. And you'll be way ahead using that vs any of the aftermarket offerings.
Post pics along the way. Us dummies like to read the pictures..

If push comes to shove you can always put an oem 066 top end on.

I will try and keep up on the photos. Dad gave the saw to me a decade ago, when I first got married and I tore into it thinking it’d be a quick fix. I found what I detailed above and boxed it up carefully for storage, not knowing when time/funds would allow for its resurrection, young and newly married-read as broke lol! As time and career progressed I’ve got less time, but more money, so projects like this can finally start.

Honestly, I have a vision to one day build a house, and in the man cave/den have a large vertical peeled timber with a lot of character with this saw plunge cut into/through it. Probably after I get a bunch of use out of it. Heirloom style.

Anyway the jug and piston were in ok shape,

I have a 046 that I found at the dump, no compression due to stuck rings and some scoring. Took my time using fine grit sand paper and scotchbrite pads to smooth down the score marks on both piston and cylinder and replaced the rings with new Caber rings and the saw fired right up and has been working great.
