I think a baby pooped in my oil pump

:huh: Found this inside my oil pump during my bottom end overhaul. Yuck.

how often do you change your oil?

Once every ten years, whether it needs it or not.

the recommended oil change is 30k miles or 3 years, no wonder it looks like that.

:side:
But seriously, the bike has been sitting in my shed for the last ten years. I'm going through everything before I even try to start it.

That's what Motul synthetic looks like after a decade. :S

:dry: It would be an opportune time to clean that part before reassembly.
Don't tell me... :blink:

:laugh:

You were very smart to take a look in there. Otherwise, who knows what damage that sludge may have caused if pumped throughout the oil journals, bearings, etc. Ed

"You were very smart to take a look in there"... Amen to that one Ed...
Simple Green the piss out of her innards, oil passages, and with everything follow up with air & clean every nook and cranny... Yeah it's tedious but she'll be like new when completed.

As for a 30K mile/ 3 year oil change recommendation on a 30 year old design, really... ? :blink:

I think I may be due for an oil pump grunge bustin' - it sounds like a bearing is about to spin and then it clears up.

Yeah, I'll definitely be re-checking all of my oil passages. I gave everything a good shot of parts cleaner and compressed air before I put the cases back together, but I think I'll do it again. And maybe once more after that, just to be sure.

I found a little of this sludge around the sides of the oil pan, and a bit at the bottom of the clutch housing, but nowhere near as much as what was in the pump. I wonder why so much of it collected in there?

Man, I sure am glad I popped that screen off. The crud wasn't really visible from the outside, but there was some old pieces of sealant and other debris on the screen, so I thought I'd better take a look inside. Then I was like :sick: .
