calling Stihl hybrid builders

[wcorey]

I just sat an 044 cyl on an 036 case and it at least sits flat with no interference from anything.
Intake boot lines up, a cooling fin needs trimming for the chain brake to trip.
I don't have a 10mm 044 piston or crank so that's as far as I go...

I would leave the 36 crank in it, otherwise your opening up a mess with the bearings, seals, oiler, clutch.... n'stuff

Where did you find that spreadsheet?

but just think how cool I'll be by doing more work than it's worth just to say I did it.

With the name slug and 3dcart and the magic of googling
I get this

Ive got a 360 case for ya road.

 

[EvilRoySlade]

thanks, I just tried 3dcartstores and got domain service stuff.

Maybe I am thinking about this wrong, but if the total stroke is 2mm different, wouldn't you only have to take 1mm off the base?

To be more precise I'd take just enough off the base to put the squish where I want it.


The bore on the 044 slant fin jug is right about 2.4mm taller than the 036. That measurement was taken from the base to the edge of the squish band.
Both the 10mm 044 and the 036 pistons have the same pin to crown height. The 044 skirt is 1.6mm longer.
That puts the cut pretty close to 2mm if not using a base gasket.

Ok that makes sense.

I'd look for other piston options.

I know we've been down this road before with the 036 and there aren't many options. But with a new agenda it would be worth another look

I'll say it has been done before.

It worked out pretty good from what he said

Canadiancarguy did it years ago, it was a lot of work from what he posted. He said the gains weren't worth it.

Adam Clarke did one.

 

[Deets066]

I bet @Stihlbro would have some insight

 

[jacob j.]

Adam Clarke did one.

I could see Adam getting pretty good gains out of one- he's done some awesome builds. His last MS-880 build was one of the best production saw builds I've ever seen.

He does build great saws

Sure does

Adam Clarke did one.

The simple question for me is did he use the 10mm and 036 crank or did he stuff a 440 crank in a 036?
