Stray pin in the bottom of my 850 engine

[Matt Lund]

Help, as well as the pile of aluminium shards that was my camchain guide holder and a 17mm thin washer i have found a collared pin in the bottom of my engine! the pin has a diameter of 3mm, is 10mm long and has a collar/bush that rotates freely on it with a diameter and length of 6mm. both ends are slightly peened over so this collar cannot come off the pin. My engine is a 1980 GS850GT engine so no kickstart mechanism in it and i have studied the diagrams and cannot find this pin in any of them. does anyone know what this pin is? i know the head has been off before by a complete idiot who put silicone all over the gaskets and i think it could have been dropped in the engine by accident and is no part of this engine.

thanks for the replies, i'll upload a pic but best description is a chain pin roller without the link plates.

Matt not sure what that can be. The description is not of any part that might have borken off anything else. Very strange.

If you get a chance join the UK Group on here:

Hmm that may be what it is.

[Matt Lund]

thanks i'll double check the diagrams. the pivot on the tensioner guide is still there but i may have missed something.

[Guest]

Umm...think they want a pic of the part you found.

[bwringer]

Yep, we need a photo.

Not managed to get a photo of it yet but i'll upload it to my Flickr site. If you have a strong stomach search for Dynohubmatt's Flickr photostream and look at the photo that says B*ll*cks for what i found in the bottom of my engine! You have been warned!

Umm just post it here. The lack of relpies indicates no one has gone to your account to hunt for it.

Thanks Salty_Monk. I've not quite got the hang of uploading directly yet. Grim isn't it?
