The nice thing about using Nisongen is that they will ask you to fill out
a simple chart with info that is gathered from pushing your car over a
short measured distance. The speedo is calibrated based on the info that you
provide. When I compare mine with a GPS, it is within 1 mph at most speeds
up to 70mph.

Sorry, Mr Enrico is no longer alive. But her is some info.
The speedo were
not sufficient lube at the factory. After a few
years the bearing in the
speedo would sieze. The stopped the
cable which wound up stripping the nylon
gear in the trans.
If you pull the cable down and drive, the cable should
turn
smoothly. If it jerks the gear has striipped or worn teeth.
If the cable
doesn't turn at all, the seized head has broken
the cable or the gear if
completely stripped.
The original 15 tooth gears is made of unobtainium. 16
tooth gears and up can be found. Each step up drops the
speedo showing by 3
mph.
You should replace the cable. SS has them, replace the
gear. and
Remove the speedo. Insert of sqaure drive into
the speed and try of turn the
speedo. It should spin freely.
Tiger Tom used to rebuild speedo at shows.
You can
drip and few drops of clean oil into the back and work the
bearing
back and forth. If it frees up you have only temporarly
fixed the problem.
The oil will last a few 1000 miles. You
should send the unit to Nisongen to
have the needle bearing
replaced. Note while the Alpine speedo uses the same
bearing
the units aren't interchangable.

Remove the cable from the
back of the speedo and you can either jack the car
up and put it on stands or
do it while driving BUT you must find out if the
cable is turning from the
transmission. It could be the gear on the end of the
cable. you may need a new
cable or have a kink in your housing and lastly the
speedo its self. Most
likely it is the gear or worn out cable but it isn't a
hard fix and you can do
it yourself until it proves to be the speedo, then a
professional will be
required but there are those who make such repairs on the
list.

My odometer
works although I do not know if it's accurate, but the
speedometer
does not
work.
Is that typically a cable issue or do I need to find a speedometer
repair
shop?
