TR2/3/3A Speedometer cleaning ?

[karls59tr]

Does anyone have a link to cleaning the odometer gears in the speedometer? I've heard that those gears can stick and I think that is the issue with the speedo needle sticking at 20mph.

Check out John's great thread here. Go to post 66 for the odometer part of the speedometer.

Tony Rhodes has an excellent guide for working with the speedo (last link on this page):

I believe you'll find that the needle sticking at 20 mph is completely unrelated to the any odometer issues.

The odo lube would be a little on the gears and (most importantly) in the little cup hidden on the shaft of the odo (quite a bit of disassembly needed for that one).

The needle sticking is probably the drag cup binding.
