I just brought my Hot Shot home from the garage where it
was getting back into running condition. The trip was about 50
miles and was a real blast. The car ran very well and certainly
attracted a lot of attention. One bug still in it is the
speedometer is noisy and bounces around - sounds like a gear is
bad inside. Any tips or does anyone out there have a speedometer?
In the back of the speedometer housing is a oil hole, a
little oil there may help.
I have found that noisy and jerky speedometers are
usually the cable grabbing and sticking. Pull the cable out (you
can do that from the speedometer end) clean it well with solvent.
Use a good lubricant like spray lithium grease and spray some down
the empty casing and rub some on the cable. Slide it back in and
work it into the gear by twisting.
If you oil the speedometer head use a good quality clock oil.
Never use WD-40 on either the head or the cable. It is a temporary
fix and it will be a lot worse next time.
The other problem that causes jerking with the VC models is it
is a tight bend to get it back into the drive train hump and into
the transmission, you need to keep that as large a radius bends as
you can. There was a dealer letter back in 1950 suggesting to cut
a hole through the floor above where it goes in the transmission
and run the cable inside the cockpit. I have actually seen this on
a few VCs.
