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.

When you consider the limited 85 BHP..... of all the T case I have opened the gears are always in good shape.

Another alternative to dipping the bearings is to inject some molyb. grease with the needle of the grease gun into the bearing cage.....then spin by hand to coat evenly...... messy but it works and at least they do not start dry.

Good job Junior!!!!

Jordan, that speedo drive worm gear (as someone has already said) will be fine to use. There will be no tooth load where the damage is. It would be good to dress the edges where the damage is.

I’m playing it safe and have a new speedometer worm gear on the way. I was thinking the chips shouldn’t be an issue, however when I lined up the other gear the teeth do pass over the one chip. Considering everything is opened up right now it’s easier to replace with NOS now versus down the road.
