This led to a bouncy and inaccurate speedo which culminated in a total failure. Replacement of the gear is the only repair. (Not done yet)

> The cable.   This requires further inspection as it can be  the cable failing at the ends, the cable fraying along its length or the cable casing developing  rough spots internally which snag the cable.  This can get worse as the cable gets frayed and exacerbates the damage to the interior of the casing.

> The gears and mechanical workings in the actual speedo In my Rampside  had a total failure of the workings of the speedo which was the final straw that led to my beautiful new instruments. The lead up to the failure had incorrect readings and bouncing needle.  Had I recognized it and done some preventive maintenance I might have delayed the purchase.  It could have used some grease and minor adjustments of the worn gears to keep it alive.  But that is hindsight.

> And just one more thing.  As I read through and see more notice of club members passing, I remember to say thank-you and show appreciation of the efforts, knowledge and friendship that our fellow members offer.  It is more important for us to express our appreciation  to them while they are still around to hear that.
