don't go crazy there girl, i like that long red hair

Ok guys its been awhile since I've made an update so here it goes. I dropped the frame off at the Acid Dippers last week and go to pick it up tomorrow so I will post pics when I get it back. Otherwise I have just been messing around with other stuff round the house. Today though I decided to go out and start prepping the trans/xfer case for paint. As I was taking a few things off I noticed that there is some rust on a lot of the gears inside the transmission. Take a look at these pics and see what you guys think. Can they be salvaged?? I sure hope they can still be used!!

This can be a tricky question. If this was my transmission, I will dismantle it, give a good cleaning to everything, and polish the gear teeth with some fine wet sand paper. All the bearings will need to be replaced as you can see on 2869ral post about Transmission Teardown/Rebuild.

It's possible that you'll end up with a little bit of noise, specially when running in third gear (most used and high speed), due to the unevenness of the rusting that has taken place between the gears (the ones shown in your second picture). And you will need to change the oil after some initial miles to get rid of additional deposits.

I will be concerned of the status of the needle bearings at the split between the input and output shaft. See the 2nd page on the above thread to see how 2869ral solved sourcing this part. The problem is that the needles run on the surfaces of the shafts, so if they are badly rusted, this might be a problem. I will try to check this area first.

Good luck

Thanks Esteban,

That's what I figured that I would have to do. I just hope I can put it all back together!!

did the p o let the rig sit for a long time reason for the rust or was the gear oil neglected and not serviced properly? this makes me think i should tear into mine and check.

Sleepy,

I think it was a combination of both. I know that it was left outside for a long time with no attention, and that when I opened it up there was no oil in there really, just a watery sludge in the bottom. I should have opened it up long ago I guess to take a look in there but not much to do about it now but clean it all up, replace the seals and bearings and hope that it doesn't eat itself apart!!

If the pitting isn't real deep, i wouldn't worry about it too much, especially on the straight cut gears. Straight cut gears are a bit noisy to begin with. Helical cut gears are quieter, these are the ones that are going to have a problem if they are pitted bad. Check all of your bearings, and the seal race in the last pic concerns me. I may have a spare for you. I will check tomorrow when i get home. Chances are your pocket bearing is ok. Keep your fingers crossed. These transmissions are very easy to reassemble, so don't stress it. PM me if you have any trouble, and i will give you my cell#.

Looking at those pics again, those helical gears look like they are pitted bad. When you get this apart, dip the iron gears in MURATIC acid, it wont take long. Im not sure how this acid will affect bronze bushings, so don't soak gears with bushings in the acid. Wear goggles and gloves, and keep water out of the MURATIC acid it reacts violently when exposed to water. But this will clean the iron parts well. After that is done polish all of the gears with Eagle One chrome cleaner. This will take some elbow grease. But this method works great. I wonder what the transfer case looks like? I will look and see what extra parts i have. PS you can rinse the parts with water afterwards, just don't get water in a large volume of acid.

The transfer case is spotless so no worries there. I have pulled the trans all apart and ordered all the bearings and seals that you had listed in your other post. My loose needle bearings look good so that's a big plus. I just need to clean them up and once I get all the parts put it back together. I was going to try using a wire wheel on the gears first but if the Acid is a better method then I can go that route. I do need to locate that spacer and the 3 ball bearings inside the synchro, those are pitted as well (oh and thanks for warning a fella that there are spring loaded ball bearings inside this thing that will shoot out all over your garage!! ). If you don't have a spare spacer then I can just have my local machine shop make me one, shouldn't be too expensive. Thanks for all the info.
