Is this normal? UPDATED

[88_pony]

This is the kick start input on the case. seems to have wear, and the oblong shape has me wondering.... I looked online and couldn't find a clear picture to compare.

To be honest, that's not something I ever looked at. What you're seeing could be normal for all I know, and even if it's not, I don't think I'd be too concerned with it. That kicker shaft isn't spinning all the time. It only turns any time you use the kicker and not at a very high speed when it does.

thanks for the reply! I just pulled the cover off the other motor I have. It is the same on both motors. The post was mainly to avoid tearing that cover off. Cheers!!

Inside lower case top hole just seemed odd shaped to be normal, trying to figure out where all the shaving came. Looked for picture of this, but could not find anything.

 

[88_pony]

located on the opposite side, if this helps to id where it is. I removed the screw but could not remove the shaft

 

[88_pony]

Anyone?

I'll look in some empty cases manyana.

Thanks gggGary! Regardless im using the case, I am just looking for the cause of this filing filled oil filters... I have not found anything yet that is the definite cause, so I am trying to X everything out that is out of the norm. Thanks again for the help!!

That's an idler shaft for one of the starter gears. There's nothing behind it to shed metal.

Thanks for the reply! yes the picture of the Idler shaft was just to help with the location of where the hole in the case is. the hole is behind the gear. the top one in the picture just seems out of place.

Looks to me like a casting/machining flaw. Prolly been there since it left the factory. If something was "chewin" on it, you should see some evidence of that... like jagged scrape marks or something along those lines.

Just looked inside my mockup cases... I see the same 2 holes.

 

[88_pony]

Thanks for the replys! I guess the search continues for whats making the filings. Regardless, getting into these motors is fun!

 

[gggGary]

Didn't find any open cases, they are "out there" somewhere. I'm going with what @Jim sez; just a casting void, flaw. in 88_pony pic above you can see the flow marks also. These XS650 castings are not the same quality as the stuff done nowadays, metallurgy HAS advanced a bit in 40 years.....

If the filings are Aluminum then another possibility is the front camshaft guide. If the rubber has deteriorated or delaminated from the guide, which is usual after 30+ years, the camchain will wear away at its Aluminum base.

That usually generates "powder" though, not shavings. Your drained oil will look like it has metal flakes in it (which it does, lol). Something like this .....

 

[Paul Sutton]

Another more recently highlighted issue was wear in the oil pump which definitely gave shavings. What other possibility are there??

 

[88_pony]

yeah so far the oil pump is my only spot with noticed wear and play, the engine will be going back together next week. I have another side cover and pump.

 

[gggGary]

clutch hitting side cover when pulled, crank weight scraping crankcase. shrug.

Different angle to the pic in this thread........is it the light or are the teeth damaged????
