Good Afternoon All
Not sure where to post this. Driveline issues seemed appropriate.
With the Part Barge ('65 Newport) in dry dock for the winter, I am addressing some 'gremlins' that pop up from time to time.
One of them is the speedometer. Every now and then (no reason that I can find) the speedometer needle will just start slamming from side to side. It will stop after a couple of miles and may not do it again for weeks. This does happen on the first start of the day.
Anyway the following is what has been looked at so far:
* Speedometer Cables (both) new and lubed. Car has add-on cruise control. Cables are not kinked or in tight radius.
* Cruise Control servo, rebuilt.
* Speedo drive pinion, no broken/chipped teeth
This brings me to the speedometer itself. I removed it today for a look-see. When I opened it up there was a black grease like substance smeared over the rotating assembly. I have had a few speedometers opened in the past and do not recall seeing grease. I do not know if someone has been in there before me.
Anyway is this normal? Should it be cleaned and re-greased? How do you clean it? (I do not want to disassemble the drive mechanism) .
Attached are a few pics .
Thanks to all who respond.
