Stihl 044 early 10mm repair

[mtnfarm]

Early Stihl 044 with 10 mm crank.

Need to replace the crankshaft. I realize the 10mm crank is not available. I see some folks use a 12mm crank and replace the piston to make it work and then reuse the Oem cylinder. Will the 12mm crank fit in the 10mm case?

Also, would anybody have a good 10mm crank on a shelf that they would be willing to part with?

I appreciate the info in advance. Thanks!

The 12 mm crank will not fit a 10 mm case without some clearancing work.

Post an ad in the classifieds here and in the other forum. I’m sure someone has one available at a decent price

Every part is available if one wants to work on finding it.

just interested- what do you have to do exactly to the old cases to fit the 12mm crank?

I was wondering the same thing. Following along to see what folks say. I believe it’s sanding some of the cast-iron on the crank and replacing the piston with a 12mm.

There are two different approaches I know of and have done to fit the 12mm crank into the 10 mm case. First one I did I ground out just a bit of the crankcase itself to provide clearance for the crank counterweight, was just a little at the bottom of the case inside where the counterweights rotate. On the second one I did I removed a bit off the counterweights themselves, was an easier procedure. The two saws went back to work around 2010 and still out there mostly used for firewood duty.
