What is this part for a stihl 066

[Rykirk]

I acquired this saw in 2017 for $50. It needs work and cleaning. I came across a plate behind the chain sprocket cover which seems like they pulled it from another saw and put it in this one. The screw which takes it off is missing and it seems the only thing holding it in is the metal under the two bar mount screws. Also this plate covers the white cap partially. Is it me or does something seem off about this. I tried to find the part in the IPL but could not find it.

Also is that stud pin supposed to be on an angle like that?

That is an alternate version of the inner bar plate that Stihl did not use widely. I don't care for them - bit of a PITA to get off. See these IPL pages.
The bar adjuster pin should not be bent like that. I'm guessing it can be straightened out after you remove the plate so you can remove/diddle the adjuster mechanism.

Looks like there is two part num for this. Dang would have been nice just to unscrew this. I guess the only way is to bend those metal flappers out and up

Roger that - PITA. The screw-attached version is SOOO much easier.

Think I'd replace the bent fixing stud instead of attempting to bend it straight. It's a cheap part. Threads look wonky anyway.

Those plates did one thing OK. The helped to hold the bar on when installing a chain. Are they a PITA to remove? Yup. An idea whose time came and went.

Looks just tilted down to me rather than bent. The bar hole will keep it in place.

Took the plate off with force using a flat blade screw driver. Got to get underneath by the bar mount screws. I thought the metal flappers were underneath but they're not. Good thing that plate bends a little

The biggest annoyance is the clutch cover from a standard setup doesn’t fit these. Though these bar plates are thicker, more durable and hold your bar captured which is cool, unless I wanted to keep it original I’d suggest you prise it off and install the standard one with screw.

Edit sorry just saw your last post.

Removed the clutch cover aaaand... this. Clogged with dust oil balls in every nook and cranny. Took me quite awhile to clean up using carb cleaner and compressed air got it looking decently clean

Might want to replace the chain adjuster parts/assy.

And pull the whole clutch and clean behind that and the brake assy.

Flywheel side might need a bath too?

Maybe I work on too much junk. But, I don't see anything wrong with any of it other than needing cleaning.

In day to day real world, give it a good cleaning. Look at the adjuster peg for cracks. If none, probably will go a while.
But the cleaning is the BEST thing you could do for the saw right now. Look it over good. Replace worn out parts. It's called maintenance.
