[DML] Re: Angle Driveless Speedometer

["David Teitelbaum" <jtrealty@xxxxxxxxxxxxx>]

You're right Bill, I forgot that failure mode. Point is there are many places for the system to fail, especially if one part is making the others work harder. Another point to mention, in the service liturature  it was ADDED to lubricate the angle drive at EVERY service. I guess DMC started seeing angle drive failures early on and thought increasing the servicing of the angle drive would help. It certainly can't hurt. Again, putting that brass sleeve in only pushes the failure point further up the chain. If something (like a dry cable which can be very hard to turn) is making the whole drive system work harder then *something* is going to fail. If it's not the angle drive (because you removed it) then maybe a cable end will fray. None of the parts in this whole system are meant to work very hard and really shouldn't have to unless there is something wrong.

The angle drive fails if not properly lubricated or if there are any problems "upstream" causing it to work harder than it should. On many cars the support bracket for the lower cable is broken or missing. On some cars the lower speedometer cable is too long. No one ever thinks to lubricate the speedometer cables until something breaks. The drive cable that runs through the spindle winds the wrong direction and is sometimes too long. I personally have seen parts come loose inside the speedometer head and bind up the mechanism which could eventually cause the angle drive to fail. To fix any one part without considering all of the others will just cause the next "weak link" to fail. Knowing that on many cars (not all!) the angle drive can work well for a long time means that on a properly maintained car it is possible to keep the original parts going. This points out that attention to detail and proper maintanence can go a long way to keeping the whole system working. Bottom lining this:
