Odometer problem- 1972 250

[PaVarrieur]

I repaired the speedo on my 1974 280c. I followed all of psfred's instructions on the repair except the loctite. I used a very small drill and bore a small hole into the zinc gear. I then used a tiny set screw that was bought at a modeling shop and screwed it into the gear. The zinc is soft enough that it created its own threads. Has worked great for 6,000 miles. Hopefully, my next weekend project (front and rear windshield seals, shift indicator) will turn out as sucessfully.

Yep, on strength of this thread - just fixed odometer on the 116.

What worked for me was backing out the spindle from brass gear end.... just far enough to leave the zinc gear dangling..... then added less than 1 drop of locktite on end of needle to the exposed inner surface of zinc gear where it was sliding on spindle.

Tapping on next gear over, single mile indicator, while locktite hardened and spinning the speedo gear with Q-tip while 'high-strength' locktite set in about 5 minutes prevented the spindle from seizing at its end point.

Only hazard for me was nearly losing the speedo peg that fell out on removal of speedo from instrument cluster.

If done again, I'd set the zinc gear with two star gear teeth at 10:00 position..... saving lotsa time spinning the speedo gear to see if odometer works.

I know some folks just love to tinker. However, if you want somebody who repairs speedometers, I highly recommend Patrick to you. He can be contacted at: bmw_e_mb_w@yahoo.com

He rebuilt the one on my SL for $120.00 and it works like a top. The dealership only wanted $800.00 for a new one.

I'd have just tried this well documented approach and I am glad to say it has worked. I did not have to remove any of the wheels, managed to get just enough space at the edge of the shaft to get the loctite in and now it works perfect.

Thanks.
