Where did this screw come from

[Theo]

Is the washr a captive one or can you remove it from the bolt?

What is the exact size of the bolt across the thread?

Use a thread gauge and tell us exactly what thread it is? It looks too coures a thread for the normal 6mm thread (6 x 1mm pitch).

Use a vernier to take these measurement if you can.

It's a captive washer.

Using vernier calipers the measurements I got are:
Master Diameter: 5.842mm
Pitch: 1mm

Hope that helps identify it. Thanks.

I would tend to concur with the earlier comment that it looks like it could be a clutch pressure plate bolt. This bolt for the clutch has a captive washer that measures 20mm across it's flats, and the bolt is 16mm long and is 6mm x 1mm pitch.

I don't know how it got in your sump, but I would not worry about it. Put the motor back together and ride.

this is wild..!

#7's came from the clutch springs, but if the washer is captive.. what he said.

I found (The hard way) an extra cam sprocket bolt inside a motor. It maybe a little fat fingered assembly worker left a present on a monday morning.

... but only after verifying that all of your clutch bolts are in place.

Unless someone advises otherwise, I think I'm going to do what you said. Just put it back together and forget about it.

All of the clutch bolts are in place. A while back though, the PPO changed all of the clutch bolts and he might have left one behind. That's the only thing that makes sense.

Thanks to everyone who has replied.

Steve, he answered in an earlier post that he had checked the clutch out. Everything there was OK.

OK, I missed that post. As long as it's verified.
