Bonneville America Forums Forums Technical Forums General Tech Cam Backlash pins

I posted a few months back on pulling the cams on my Bonnie to see if the cam backlash gears were not properly installed under spring tension. Well, I got the Haynes manual and am proceeding with the teardown. I note the pin holes do not line up, so appearantly the cams have been pulled with the backlash locking pins in place.

Bottom line is I need the backlash locking pins for the cams. Several of you made your own as you had access to a lathe. I have a drill and a file Anyway, I called the dealer and asked if he had the backlash locking pin tool # T3880330. Got the big "duh" and he said he needed to call Triumph on Tuesday

Have any of you come up with a locking pin thats easy to make, and works?

Look at the 5th picture down at this website. You don't need the special tool, just anything that has the right diameter that will poke all the way through.

Check out the Tools thread in the Tech Vault. The dimensions of the retaining pins and the backlash retentioning tool are posted by Jay there.

I found the largest screw that would go in the big hole and filed some of the tip down to go in the smaller hole. Slightly out of round, so I stick it in there and give it a twist, wedges firmly in hole.

I made a set of pins around about a month ago.
If you can wait for the USPS, you're welcome to them.

Again, yous guys are great. Bucky, check your PM. i'm gining to try to manufacture a pair using 1/4 stock. We'll see how it goes.

BTW, Dinqua's site is amazing and informative. I was up @ 0500 reading the Post on the installation of the 900 Kit. Excellently written with great photos.
When I told my wife I was at the Dinqua site all morniing, she thought I was into porn for sure.

I ground down some el cheapo torx bits to a single straight taper with a bench grinder, testing and fitting as I went. It took around 15 minutes or so. A light tap into place and they fit fine.

I would avoid trying to make the two diameter style pins without a lathe. That's a whole lotta surface area to get right. A straight line tapered pin is (IMO) easier to create by hand, and does the job just fine.

Thanks Bucky... sounds like a plan

The pins are relativity easy. Tensioning the backlash gear is extremely difficult without the tensioner tool.

BTW Cycle Riders in Orlando failed to pretension my intake camshaft gear. Hum I wonder when the last time was that I brought my bike to them?
