This was stuck to the end of my magnetic oil plug. Any ideas what it might be. It is a odd shape. Cylindrical but with rounded ends and flat sides. It has perfectly formed flat spots either end.

There is a possibility it just got picked up by the plug during the oil change (eg off the garage floor) because I didn’t notice it till I went to replace the sump plug.

It doesn’t look to be chewed up or marked.

Looks like it might be a roller from a bearing? Then again, I've got bearings on the brain at the moment.

Looks like it's been rattling around in there for a while if its a bearing roller. Would have been a disaster if it had got caught between gears.

Sits on reverse selector arm, in bottom of remote box? Engages reverse selector rod. I think... Maybe.

It looks like a roller out of the Input gear support bearing, that has been bouncing around in the gearbox for a while.

I would guess at it being some sort of selector detent like what the Doc said.

Hard to see from pics, if no hole in it I agree it's probably an outrigger bearing roller. Somewhat beat up.

that's kinda what I was thinking, it's the right size, but it's a little bit too perfectly shaped - they're a nice square cylinder shape (the only type I've seen have been a cylinder, there may be other shapes out there)



if it was picked up off the garage floor, what would it have been doing there? where might it have come from?

Yeah I’m thinking more likely not from elsewhere (just me being hopeful) because I think the sumpplug just stayed in the drain tub. I thought it might have popped out of a socket spanner.

I actually had a gearbox circlip come out with the oil years back, it’s in a thread on here somewhere.....
