A dummy and the Stihl ms441c

[redline4]

Zapped the clutch off.
For you dudes with a clue, is it toast? What's the best way to determine if it is?


Plus, to be top 3, doesn't it immediately warrant a new one??

 

[redline4]

Stop rubbing it then.

It's mine now.
I'll rub it however I please.

Only if you already have an oem clutch of someone else’s

 

[redline4]

Clutch off, washer out, oil pump drive gear..



Oh look, there is an oil pump in there..

I've reused some pretty nasty clutches, might ruff up the edge with 220 grit and check for grooves or high spots . If it has either pitch it or it'll wear the drum like a brake drum with bad shoes.

Run it.

Popped the flywheel off.
Cast in key..



This small cover here

Pops right off by squeezing these tabs.


2 screws and oil pump pulls off.
Don't forget this seal..

 

[redline4]

It looks like the piston may have contacted the case?


Remove the snap ring


Oil line


And using the heat and beat method, cases are apart.


Little scrubbing in the parts washer..
And with the broken flywheel side case, it's just the right amount of ugly.


I plan to keep it, don't care that it's missing a chunk, and right now have other things that money for a half would be better spent on.

 

[redline4]

Bearings off the crank.
Both bearings, including the proprietary PTO side bear the NTN name.


I will be putting an oem PTO side bearing in.
The flywheel side was on backorder, so I obtained an NSK Japan bearing that will be used.

That connecting rod end is awfully urply purply, like it got really hot.
Make sure it's not galled at all.

It looks funky, but feels fine. The big end bearing shows no discoloration. I can't feel anything "not right" with it.

Isn't the star shaped mount supposed to go where your chunk is missing?
I think I've got a spare flywheel side, if you can wait for it to be mailed. If I do have it ,it might be a non C but can be made to work, and I don't need anything for it.

If it got hot enough to discolor the steel connecting rod that badly while running, the thin bearing cage would be melted.

That's just from heat induction treatment of the rod ends during manufacturing.

Stuff like that makes me nervous.(building a hi perf saw on)
He checked it out though, so I'm happy.

You can see the bearing cage in this picture. It isn't discolored at all.

The part where the AV mounts bolt up is still there. It's the part that drops down in front of the spring that's broke off.
I appreciate the offer.

Case half arrived from @Maintenance Chief .

Here's the 441c


And here's the 441


Big difference in casting for room for coil and wiring.

And, can't grind it out without breaking through to the outside...

441c on left, 441 on right.




So, it looks like if a guy were to have 441 cases, a 441 it must remain.
But if you have a 441c and it craps the bed, the non M-tronic coil, carb and stuff will fit if it were desired.

Bummer.
