Need help with Stewart Speedo cable repair

Post by AdminJeff » Sun Nov 03, 2019 12:14 pm

One of the ends of the drive cable (Speedo side) is perfect and formed from the spring cable itself. The other end has a plastic ferrule that is attached to the spring cable and it has been deformed, twisted and has a groove that allows it to spin and is at the end of its useful life.

To fix it I cut a thin piece of shim stock and used that as a crutch. It's only a matter of time before the plastic breaks for good. Anyone know if the plastic piece is available in a metal replacement?

I saw that on their site. It's the whole cable. I only need one end. I might need to spin up my "new" South Bend lathe and see what I can come up with to replicate that plastic piece. I think there's enough room inside the cable for a small Allen head set screw similar to the drive end.

First, I am no speedometer expert.
Second, I wonder why there is a sacrificial end on a modern speedometer cable, if not to sacrifice itself, if needed
Third, I wonder why there is so much resistance to rotation that it has in fact, sacrificed itself

Is making a stronger part out of metal, a prudent course?

cables are cheap; speedometers not so much.

This is the part I need. Of the many of Speedo cables I've seen and disassembled from cars and motorcycles from the 60's thru the 70's, I've never seen one with a plastic end like mine has. Someone somewhere at some point in time thought this up and clearly it was not a good solution. This type of plastic is quite pliable and easily distorted, and screwing a metal set screw into soft plastic is not a good idea.

I've emailed Steve Lang to see if he'd sell just this piece.
