044 Cylinder
« on: May 13, 2013, 07:42:06 am »
Not a Stihl guy but came across 3 MS440 for $100 ea.  2 are running the other has broken gas tank (gonna try a redneck fix on it) and broken cyl.  Probably keep it for a toy.  Always read the old 044 10mm wrist pin cyls. make more power.  Is the good 044 cyl a Mahle if so what are the casting #'s?

Look for 45* angled fins on top of the cylinder.
I have the Ser#'s written down at home, I'll get them later.
Although rare, some early 12mm saws had angled fins too.

The 10mm cylinders had a smaller chamber and lower exhaust. The number is 29 382 283 or 129 382 283

Wigs would be the man to ask about the varying 044 cylinders.  Guy is a walking encyclopedia.  Older cylinders had lower exhaust and larger trans, that is all I know.  ???

There's lots more differences than ppl realise. The 10mm even uses a slightly smaller crankcase, it has crankcase stuffers unlike the 12mm.  The main bearings iirc are also different. The 10mm has a red on/off/choke switch and the 12mm black.
The angled fins on the head/ barrel where carried over on some early 12mm saws. The easiest way is checking the seriel number even tho a few 10mms have turned up with higher numbers than what they (stihl) give as the changeover.

A good running 10mm 044 will run as good as a muffler modded 440.

Doesn't look right , shouldn't that be 8 numbers?
