stihl 044 building
« on: July 31, 2013, 01:26:34 pm »
I hate to ask, but what is the 10mm 12mm difference with the 044. My mechanic didn't know what I was talking about. Judging by the serial number, this saw is a 10mm. 10mm what?!!!??? Thanks for the info in advance and feel free to throw out any other tips and advice this is my first go at this, Brian

I dont know these well but guessing wrist pin size.

Digging up info.  1128 030 0406 This crankshaft has a 15mm piston pin bore. Model 044 chainsaws built before serial number X 29 382 283 (1994) have a 14mm piston pin bore. See part number 1128 030 0401

You are right, it means 10mm piston pin or 12mm piston pin. If you have a 10mm, they typically make a better runner because of more aggressive port timing numbers. This is from what i have read.

Thanks guys that is good to know. I am ashamed to say that the folks at two local dealerships acted like I was crazy when I brought it up telling me that it had a 50mm piston. Oh well :o Thanks again Brian

I've been working on these saws lately and I sent a email to Stihl and this is part of what info was sent of me



"... piston pin switching from 10mm to 12mm at serial number 129583701"

All 044/440's have a 50mm bore.
Early 044's had a 10mm wrist pin (see serial # above).
The early 10mm saws had more aggressive port timing.
Also had lower volume crank case and transfer tunnels which increase charge velocity.

They are strong running saws, I own 2 of them  :-*

The downside is that they had weak bottom ends

Cut4fun recently had a 044 at his house to work on. It was very impressive. I have several other brand 70cc chainsaws and this 044 for being stock was better than all of the stock ones I have.

I might add that he had a 046 along the same time and it wasn't as impressive for its size as the 044 was.

The 046 just didn't have that magic sound.

You can identify a 10mm 044 by the orientation of the cooling fins on top of the cylinder....10mm saws have angled fins and 12mm saws have straight across fins.

Make sure your Stihl gurus don't put a 10mm piston in a 12mm jug as there is a good chance of a ring catch, due to differences in port positions.

But as I been told you can put a 10mm cylinder on a 12mm piston. This is a very desirable option, giving best of both worlds. Also some early 12mm cylinders had the 45° fins. Hope this is of some help, I've been looking for a 10mm saw for some time, I'll find one eventually  ;)

10mm saws have angled fins and 12mm saws have straight across fins.

Early 12mm saws also had angled fins. The only true way to know for sure is to run the serial # or measure the wrist pin diameter.
My 10mm 044's will outcut a newer MS460.

The 10mm saws have a sound like no other 044/440. If you've ever ran one or heard one run......you know what I mean.
