[TR] TR3 Speedo Reading

Bill,
If you are comfortable you have tried everything else, give Morris at West
Valley a call, he is good about advising things for you to try before
sending it back.

     I had my speedo rebuilt about 40,000 miles/8 years ago by West Valley
Instruments and it worked fine.
 About 7 years ago (30,000 miles ago actually) I rebuilt the engine and the
car was off the road for about 18 months. When I got back on the road the
speedo  was flailing everywhere between 20 and 80 mph. I put a new cable in
and routed it through the clip behind the engine in front of the battery
box. It still did it. I routed the cable more gently between the carbs and
over the valve cover to avoid bends. It still is messed up. I just bought a
new cable and routed it gently again thinking that maybe my last new cable
was messed up from new. It still doesn't work. The speedo appears to move
quite fluidly like it is lubed inside and not jammed in the
instrument.     The car has an
 A-type overdrive and I am using MOSS's OD 96
inch cable.     I am thinking about hooking the cable to an electric drill
and
seeing if the speedo reads okay.     My next step is probably sending the
speedo back to West Valley for cleaning and lube.     What is causing this?
Are there other tests that I can do?     My track record with disassembling
TR
gauges is not good, hence my relationship with West Valley Instrument.
Any
help would be appreciated.     See you at Triumphest.     TIA,
     Bill in Tehachapi
