speedo cable spinning in the speedo drive gear

[cschluender]

hello,

Found this thread in my research ( https://forums.roversnorth.com/showthread.php?7298-Wonky-Speedometer ), and hope to resurrect the topic; I am having a similar issue, speedo cable spinning in the speedo drive gear.

background:
- speedo gauge didn't work when I received the truck from prior owner
- first I replaced the speedo cable with the LR OEM part (https://www.roversnorth.com/parts/90...ble_series_iii)
- tested with a drill and the new cable and gauge worked perfectly
- reinstalled the cable to the transfer case after finding 3 new 2BA screws to attach the mounting plate on the cable assembly

test drive and gauge still didn't work...

- pulled the cable off the transfer case, and pulled out the speedo drive shaft assembly.
- gear teeth good, but found what should be a squared off female hole to receive the speedo cable drive was striped, round...
- found NOS speedo drive gear online (part number: FRC1536), new seals from RN and installed the "rebuilt" assembly
- test drive yesterday and yet another failure... still no speedo gauge working.

Today, I pulled it all out and tested the parts individually again, the issue is the speedo cable shaft is a square cable which is 0.1" square but the square hole in the drive shaft is 0.125" square... more than enough for the speedo drive shaft to spin around cable without driving the gauge.

anyone else experience this? any solutions? do i have the wrong parts???

thanks in advance!
