Stihl 044 case......D'oh! - with pics

[emathews82]

im pullin for ya

Being a NH native (deerfield) and a saw junkie who just picked up an 044 that is in pieces I wish you good luck. I'll certainly look forward to your seeing your progress. I hope that my project is going to be a bit easier. Mine is; Bottom end rebuilt w/ allegedly stihl bearings, cyl looks good and ordered a NWP piston from Baileys. 28" stihl bar with a toasted nose, wheres the best place (anyone?) to get a replacement bar nose? missing parts onmy project saw included: oil pump was missing the hard line to resivoir (replaced w/ used from Chainsawr.com), brake band (also from Chainsawr) and the following from Baileys; Bar Nuts, chain, muffler bolts, air filter, clutch drum, drive sprocket + bearing. + felling dog/bumper spike off ebay. I picked up the saw for 160 and im roughly 175 in parts into it. Im hoping to make a bargain beast!

cheers!

P.S. anyone got photos on a muff mod for this saw or am I just mental for not being able to find them already posted?

After porting.. This is my 2nd ever port job. Please be gentle.

Looking good now! Let us know how the welding goes. A friend and I are trying to gear up to be able to tig weld magnesium for just this sort of problem.

It was going to cost more for welding rod than for a new (used) case half. I bought one for $27 shipped off of ebay.

That's what we found out too. They get some serious cash for the magnesium rod!

I would try to get a little more arch in the exhaust port roof just to be safe.

How did you prep it for paintwork? wire wheel or blasting?

+1 but there needs to be an arch both top and bottom of the exhaust port cause the rings travel over both.

A bit of everything. Pressure wash, dish wash, high pressure air, soda blasted the corroded parts, then scotch bright, the duplicolor self etching primer.

Gotta laugh about the dishwasher, but i have seen quite a few who do that... father in law has a large sandblaster, but figured it would get sand impregnated into the softer metals. thx for the info:msp_thumbup:!

Both sides have a decent arc on them now.


Port timing numbers to follow in about a half hour.

Starting port numbers were:

Ex 102* ATDC w/ 156* of duration
XFER 117* ATDC w/ 126* of duration
BD = 15*
Intake = ? whoops.

Looking forward to seeing what you end up with.

Looking forward to seeing what you end up with.

Now:

EXH 97* ATDC and 166* Duration
XFER 120* ATDC and 120* Duration


How does that sound? Probably ought to raise the transfers a tad????


The new numbers are with a Guiness can gasket. The squish is 0.020" with the gasket and 0.015" w/out. The original numbers are without the gasket.

I'm a little sketchy on how to check the intake side. I started the duration measurement right when the skirt closes off the bottom of the port. Is that correct?

If so, my numbers are:

EXH 97* ATDC and 166* Duration
XFER 120* ATDC and 120* Duration
INTAKE 75* ATDC and 110* Duration
BLOW DOWN 23*

What do you guys think?
