so...I was changing the oil on my 1500 that I replaced the bevel gear bearing on (first oil change after initial clean out and repair...about 250 miles on this oil) and I pulled the pre-filter screen to get everything out. The screen was clean and I could not find any metal shavings from the bad bearing when I emptied the oil....however, I did find these two small ball bearings (3-4 mm in diameter). Any idea where they would have come from internally? they are far too small to have come from the bad bevel gear bearing and none seemed to be missing from it when I pulled it....any ideas would be greatly appreciated...
ps...the engine seems to run just fine without any excessive knocking or noise...
Part of a non-return valve of some kind?
Not trying to be a dick but are you sure they weren't in the oil change pan before you dropped the oil? They look like they're bicycle size.
that's okay...someone was bound to ask that question....and yes, I am sure...the pan was clean before draining the oil into it...
I think those look like muffler bearings, probably got back internally somehow through the exhaust valve, and ended up sucking back through the Kuhneutson Valve , and winding up down in the oil pan. .... ::).... sorry, I couldn't resist, LOL.
I do not know for sure, where those could have come from. What about the case bearings on the ends of the crank and the balancer shaft and the trans input and output shafts?? I think it would make me pretty nervous-- worth taking them to your local friendly Kaw dealer, to ask a tech if he recognizes them.
;D told you if we put them in there it would drive him nuts....
Greenbarn...helpful as always...will take your advice....
Ratman.....ROFLMAO
Greenbarn...I went through every possible parts diagram of the VN1500 engine.....all the smaller bearings used in on the internal shafts are roller bearings....nothing that small uses round bearings....but I will still take your advice and take them to a tech and see what they say....
thanks,
I have not had one apart. But the 92045 bearings in this diagram look (to me) like ball bearings... and I'm thinking would be just about the right size, unfortunately, for your mystery bearings.

That's a caged ball bearing, so there should be bits of that, too....As I remember, that was also a pretty large bearing with bigger than bb size elements...
yeah...I looked at all the internal bearings in the diagrams...none are that small....it's definitely a mystery
I definitely think Ratman may have been messing with you.... DO you keep your bike locked all the time??? 8)
You may want to install a magnet on the bottom of your oilpan
Are you still blaming me for the fire extinguisher? Now I get blamed for everything........

Yep, all things, LOL
Can't be muffler bearings, they're much bigger. :)
