How To: C15a Wire-3 restoration

[Jordan Baker]

Thanks for the help. My bad on the other part number. I read off he wrong line in the parts book when I was typing out my post.

The worm gear on the end of the idle shaft should be GM 1809534 Gear Speedometer Drive ( 4 teeth). From what you have, this part is the same as the Ford C01Q-17285-A?

Also here is the picture of different tool for removing the worm gear.


I stopped off at the shop tonight and we might be able to make a copy of the puller as found in MB-C2. He didn’t think where I had the small chips would be any issue as the other gear should just be riding in the middle.

There does not appear to be anything special about that puller. I'm pretty sure I have that in both OTC and snapon.

I think a small to medium bearing puller (the plate type that has two halves) and a little heat from a propane torch would make quick work of that job, and provide much more support to the gear.

I tried the plate type of bearing/gear remover and it quickly chipped the bottom of it so I stopped. I’ll try some heat on it tomorrow.

Did you use it flat side to the speedo drive gear ?

Jordan,once again, no knowledge on my part. What does the nut behind the gear do?
Can you use it to push the gear a bit?
If you heat the gear, a quick heat like oxy accetylene will get you the gear hot without the shaft getting hot at the same time. If you use the ring gear fitting method of using a wooden match to check the heat. That is, do not heat past the point where a match will char or "slips' easily sideways (loss of friction)
Something like a chain vicegrip might swing it off, when it is hot. I hope this lot helps.

A PDF of the pages on speedometer parts from Ford book SE 39-42 is attached to let you confirm.

Transfer case gears are all done. Well almost, just waiting for a speedometer drive worm gear to arrive from Holland. The original one chipped the threads while being removed. All new bearings, everything taken apart and cleaned up. Bearings were all dipped in oil before assembly. I’m currently just working on installing the new bearing races back into the case and cover. I also assembled the declutch shaft and carrier.
