Re: Resurrecting a 1951 Henney-Packard Parts Car

It feels as though I'm making a little headway but not as much as hoped. I had expected to get the transmission work done and installed this time at the shop but it will not be until the next trip or even the one after that that happens!
The problem is the poor condition of the replacement transmission but at least I have a plan now, or rather a new plan to meet the circumstances. Since the replacement transmission wasn't in good condition inside but had unbroken gears, I'm going to use what I can of my better (but stripped gears) original * and put the best parts together into the original case.
So to that end, I stripped both down completely except for the reverse idlers as I see no reason to remove those and in the original, here is what I found. Not only the obvious stripped gears but also the front syncro was totally fused to the input gear and no amount of hammering, chiseling or heating would remove the stuck piece. Not that it matters but I was curious if the polished surface had been damaged but clearly it had.
I also noticed that the syncro was missing its spring clips and it also was missing two needle bearings from the cluster gear. There was also the little green bit showing up on an earlier photo that turned out to be a piece of wire with connectors on the end and I also found a piece of old electrical tape inside.
The white stuff coating everything in the replacement transmission's innards seems to come off readily and the black seems to come off too but not so easily. I spent a couple hours just cleaning up the input shaft to make it good enough to use and even then, it will require the bearing from the original transmission. The surface where the roller bearing goes in the input shaft for the main shaft is not the best but I think it will do just fine.
On the replacement transmission, all the needle bearings were accounted for but some are not in good condition. However, if they are the same size as those in the original transmission which were good, then I can use a couple better ones to replace the two missing.
It turned out that the bearing surfaces inside the cluster gear are fine, or at least good enough. I'll run it through the solvent tank, then check the teeth again. The bearing races inside seem to clean up reasonably well.
Solvent tanking the main housing and doing a little hand and rotary wire brushing, I see red paint under the Packard gray. Presumably that was a primer put on prior to assembly to the engine where it was then painted gray as a unit with the engine.
* Just to clarify, this isn't the original transmission to this car. The original went into my 1951 Henney-Packard combination when that original (THIS original now) stripped its gears.
