Hitchcocks Forum

Having thought I had resolved my speedo gear issues on my CO( thanks to people on this forum) I discovered that my drive is wrong. The problem is I am not sure why it is wrong . I have been told that the rod that the cog fits to the drive comes in different lengths. Can any one advise ? I attach a few pictures to hopefully also explain what I am saying. Thanks Richard

Hi, what is the problem, is it rubbing again the brake shoes?

Yes I have tried to dry fit and it doesnt get beyond the shoes. I assume the shaft is too short .

Hi, from memory the housing is threaded into the backplate to the required depth then held in place by the locknut, that is how its adjusted. Vince

Hello, I have a C/O that I am rebuilding, I am missing the speedo angle drive and the gear wheel for the shaft, do you happen to know the ratio inside the angle drive, and the number of teeth on the gear wheel, so I know what parts I need to get thanks Ronald

The pin is a rollpin,easily obtained (google) and cut to length,have you removed the nut before inserting the drive?that should give another 1/4" that the gear should enter the backplate and may then engage .
