speedometer question
I have a 47 ford pickup running a C4 trans. The aftermarket speedo is acting up and i was wondering if anyone knows if you can run a harley bike speedometer that is 1:1 connected to this setup and if so what is required to ensure it is accurate.

Speedometer solution
Hi,
hard to say what will be the outcome if you connect the bike speedometer.
I had a similar problem on my '41 with a speedometer of a VW Bug, Nissan gearbox , Transit rear axle on 14" wheels. The reading needet to be pretty accurate in order to get a road registration in Germany. Here's what I did: I connected a electronic pick-up from a truck to a VDO Speedometer. In order to connect the pick-up to the gearbox I had the Nissan speedometer cable modified to fit the pick-up. The VDO speedometer can be adjusted in 2 way's : either you know how many impulses are generated by the pick-up per mile, or you set the speedometer in a learning mode, drive the exact distance of a mile , setting it back so it "knows" how many impulses he's got.
I set it approximatively , checked with the speed read of a GPS navigation system and changed the impulse figure until the reading was about 6% above the real speed.
Electronic pick-ups are available for most gearboxes, just check with your local reseller of gauges.
Hope this helps.
