Subject:      Re: Odometer Repair-Migrating Shaft
Content-Type: text/plain; charset=koi8-r

Hello Thomas, I got an old speedometer that is shut but gear mechanism is ok. Looking at it i noted that it is the red plastic gear that drives white plastic double gear and the other end of it, worm gear side drives the speedo counter pinion gear(beige). From your description it appears that(also noted by other listees) odometer shaft lost its tapered bushing type end part that retains it and now allows it to move enough to disengage the beige gear. Here is what i would do.Measure the diameter of the shaft as precisely as i can.Find a small piece of alum. rod ab.3/16" dia.Drill a hole (slightly smaller dia thanshaft dia) thru the center of it (the best i could) no more than 1/4 deep. Cut the drilled end off ab. 1/8-3/16 long. Push this little bushing on the end of the shaft with cut side facing out. Back the shaft up at the other metal end (not the plastic gear). It would help to put a drop of loctite inside that little bushing. I know parts are very small and it is delicate work but it can be done with enough patience. Hope it helps, Good luck Leon 85 Subwagen Westy Torrance
