Need Part-Can't Find-Not Listed in IPB

[ordy28]

Well, once I get one thing repaired, another problem rears its ugly head.  So I am trying to locate a part in the locking gas cap on my 1991 K100RS.  The round cam that moves the sliding latch.  I replaced the key lock since I broke it when removing it so I could unlock my cap.  The cam is plastic and appears to have the two holes stripped that the lock itself engages.  Am I going to have to find the entire locking gas cap assembly do you think?  Are there any BMW used parts dealers I could contact, US or international?  I was also trying to think of a way to drop in some kind of putty that would dry hard after I pushed the key lock into it order to make an impression with the dowels.  Any information would be greatly appreciated.:dunno

Speaking of information, Mike, how about posting some photos of the effected parts into this thread? Size them to 8" or so; they'll load better. Show different angles of the affected parts.

As Martin has indicated, you can be certain there are sellers of used BMW motorcycle parts in the world, and quite a few more than those he has chosen. We must resist allowing damaged-part panic to affect our rational thinking.  :yow  Try typing BMW motorcycle used parts into a Google search and an eBay search. I think there are even a couple of used part dealers who are members here. Maybe they'll chime in. You might even find an entire fuel cap for a bargain price from somebody here.

Last but not least, 3D printing might come to your rescue, but it's early for that. We all want to see what you're talking about—at least I do, anyway.

If you post the pic - I'll see if I have what you need. I know I have an extra gas cap - and I think I already disassembled it.

Scud, thanks for the reply. I'll see if I can get some picks up this weekend. Didn't take pics last night in the shed. I snap a couple pics this weekend.

Here is a "how to" solve that problem.

Excellent pictures of the cam cup and return spring Inge, i was thinking to put an aluminum plate with holes for the pins, but your approach using rivets as pin-stops looks great.  i've repaired one in which the pins were corroded off, but the cam cup was okay.

Well Inge K. pretty much showed the parts and appears to have shown me a fix.  I would like to find a good cap assembly or the cam itself rather than rivet it, but I'll do what I need to do to get ot fixed.  But here are the pics I took this evening.

Finally got around to working on the bike between work and business.  I do not have any photos, but the repair suggestion in this thread with its included photos worked just fine.  I clipped some ribbed nails instead of rivets and drilled a couple of undersized holes and inserted the nail pieces.  It worked just fine.  One note about this repair is that once you finish, the key lock in the cap no longer functions the same as before it stripped out.  Now you have almost a full turn each way with the key due to the cam being stripped and the key mechanism having to go all the way each way in order to contact the nails/rivets.  No big deal of course since it can at least be closed properly and then also opened.  Thanks for the link to the repair!!
