Cleaning a Transaxle Options

[Larmo63]

I'm pulling the trans for the new clutch install, etc. and I'd like to clean all of the black (tar?) gunk off of my transmission. What are the recommendations here? Dip it? Degreaser and manpower? I'm doing new cable, fluid too, so.....?

Ideas? Experience? Is my tranny supposed to have all that black shit all over it?

First, I had no problem with oven cleaner. Leave it in a 55 gallon drum for a couple of weeks and it could be a real problem though. The issue is time and quantity.

Second, it is hard nasty work. I prefer chlorinated brake cleaner. I work in toxicology and I can tell you it isn't good for you. On the other hand it takes no prisoners and as Mr Sparkle says, it disrespects dirt. Anything oily and cleaner than your gunk will work as a substitute. Detergents act as sort of oils, but have the advantage of bonding to water too. Pure dishwasher soap is good too. I like Dawn. I buy 3-packs.

Third. The wire brush. Dremel brushes and bigger spinning brushes actually get the dirt off when the oil is gone. WARNING: spinning wire brushes loose their bristles like arrows. I have pulled a dremel bristle that pierced my nose straight on. Note the proximity to the eyes. I had goggles on.

Finally. Paint it! Magnesium very badly wants to combine with oxygen and return to the earth. Note the erosion already present on the case. I have had excellent results with grey epoxy DP-50 covered with clear coat to protect the epoxy from UV.

I am doing my third case right now. These trannys are fun to work with and pretty straightforward once you have made some mistakes. (IMG:style_emoticons/default/MDB2.gif)
