Transmission guru’s

[rockfla]

I finally have my case all cleaned prepped and painted AND have all my NOS replacement parts ready to assemble back in the case. What do you best recommend to clean the old reusable gears, bearings abd shafts as well as a couple of NOS shafts and gears (with years of shelf dust) on them with?? ALsO do you use any gasket sealer on the gaskets??

Thanks in advance

I think a great investment is a small sonic cleaner that has heat settings - I use them for ALL sorts of things (carbs, bearings, gears, bolts/nuts, etc.). You can use different solutions in them - including ones that kill rust.

I always use 'Gasgacinch' on most regular paper type gaskets - it helps to keep them in proper alignment during assembly.

I use mineral spirits/paint thinner in my parts washer and that seems to do a great job of final cleanup to remove any old gear lube, dust, and gook. Use your air gun to blow everything dry and you're ready to go.

If your transmission has bronze synchronizers, be sure to use a good quality GL-4 (API rating) gear lube. GL-5 gear lube contains chemistry that will damage bronze parts over time.

I also have mineral spirits in the parts washer, but important stuff gets a final wash with starting fluid. Cheap, or was, and evaporates quickly

If at all possible DO NOT run new gears against old gears. I can almost guarantee you will have a whiner. Don't get me wrong it will probably be a solid box. I put a new 2nd slider against my old cluster in the T-10

A good brushing and rinse in the parts washer and blow down with compressed air, then lay them out on a clean shop towel and cover them with one. If they are going to set there for more than a few days spray them down with some WD40 befor you place them on the towel. Tim

What’s your favorite cleaning liquid and what temperatures do you normally run

I soda blast gears and on my personal cars have them REM finished. The bearings if resusing run through our parts washer cabinet and then soak in mineral oil. Fine glass beads are fine for blasting everything except bearings and brass as well.

Likely most people don’t have a industrial parts cabinet, I have a vevor ultrasonic cleaner I use for a different hobby, and it works great on bearing with distilled water and a small amount of ultrasonic parts cleaning solution of Amazon. Have to spray with brake cleaner after and soak with oil.

I'm going to try and not be the safety police but putting anything other than water in an ultrasonic is asking for trouble. I know people get away with it all the time, but at a minimum do you want to breath in aerosolized solvents? If you must use solvent one is supposed to put the part in a sealed jar or bag filled with that solvent and then place it in the water bath. The waves travel through the container with ease. Hot water ultrasonic with a drop or two of dawn dish soap as a surfactant will clean gears up just fine and they will come out smoking hot so they dry on their own quickly without flashing, usually. And you know not to stick your hand in there when its running, right? To see if your cheap harbor freight or Chinese ultrasonic is a real ultrasonic put a piece of aluminum foil in it and turn it on. The foil should be full of holes in a few minutes, if it is just an agitator it will still be a complete sheet, many of the cheap ones do not pass the test.
