My question is will it hurt to run my engine with a small chip missing from my crankshaft, on the oil pump lobe side?
The story behind the question is....
I was changing the oil in my 08 610, and deceided to check the rh side bag filter. I was happily working away when I noticed this speck near the oil pump shaft, in the rh cover.....
I pulled it out and started to freak out.....
I did a quick check and found a chip missing from the crankshaft (I think), where the oil pump shaft goes. I put the chip in there and it looked like a perfect fit, and no pieces missing. I didnt find any metal chips or flakes on any of the filters (bags, or paper).
I pulled the pump apart, and all looked well enough. There was some minor scoring on the pump pieces, but nothing that worried me too much.
I didn't notice anything else out of order, so I put the rh cover back on, and put the pump back together. The pump shaft seemed to be engaged into the crankshaft just fine. I buttoned up the bike and filled her up with oil. when I fired her up it sounded normal. There appeared to be oil flowing throught the sight glass.
I noticed a slight oil weep,and the slightest hairline crack, from/in the oil pump cover. That will probably be the easiest fix.
Should I check anything else?
Then to make it better.....while I was uploading the pictures into my computer I noticed something......it looked like chips in the teeth of the gears on the crankshaft. I ran out to the garage to take a look. Rather than dumping out the new oil I pulled the oil fill plug out and looked down the hole. I could see the gears (and the ones that they mate to) and it looked as though they were machined that way. They have a kind of slight groove down the center of them. Has anyone noticed a groove like this, or should I prepare for a major rebuild?
Any advice is appreciated.
