I,m getting ready to dig into the Tranny, Overdrive and gear box Cover. Any one have any thhoughts on cleaning the cases. I figure a trip to the car wash or use of a pressure washer first to get the real heavy gunk off. Then bead blasting? Chemical cleaners? This is after the cases have been emptied.

Any thoughts will be greatfully appreciated.

Thanks, Tinkerman
 
When I had my tranny torn apart I used soap and water followed by a spray degreaser, carb cleaner or disc brake cleaner work well. Afterwards I bead blast the casings and repainted, look brand new.
 
Someone said once that Easy Off Oven Cleaner works well on these. POR15 Marine Clean will work wonders if you have any.
 
Aloha,

As Paul suggests, oven cleaner will work and I have done it. It can burn your skin and if it spatters can damage surrounding surfaces. I did my gear box out of the car, in the middle of my drive way. You will still need to use some old tooth brushes and scrappers to loosen the heavy crud. When it was pretty clean, a bucket of hot water and detergent and scrub brush got it looking like it can off the assembly line.
 
When I cleaned/painted the engine in my Volvo, I used a putty knife to scrape off the major crud and then POR-15 Marine Clean and a toothbrush to clean what was left. It does a wonderful job. :smile:

...and then a nice coating of POR 15 engine paint for a smooth, shiney surface that is easy to wipe the oil drips from... :yesnod:
 
Powder coat it a pretty color to match everybody else's mechanicals!

Maybe if you have to completely disassemble the trans down to the case anyway as I can't imagine baking the seals being good for them. But if you don't want to do that, POR 15 engine paint is a pretty good alternative to powder-coating. It's self-leveling and dries really smooth. The engine in Robyn's Volvo still looks "wet" after two years and a few thousand miles.
