'55 Speedster Tach

#1 Post by Dan Kalinski »

This gauge works but now has developed and intermittent howl and a fair amount of vibration.

Bad bushing? Needs lubrication where the cable fits the gromet? Lubrication elsewhere on the interior of the Tach? Tach cable?

Know the unit can be sent to PA Or NH for referb but don't want to wait for months to get it back. If this is the only recourse, will wait until winter.

Thanks again for your help.

Mine did that about a year ago on the drive up to Roger’s. It was a build up of dry/hard grease just inside the instrument. It was at the base between the barrel and the threaded portion. I cleaned it out with a dental pick and WD-40. Clean inside the threaded portion, where the tach cable screws on.

what are the experts recommending for the type of lubricant on the axle and the brass bushing?

Thanks!
