Finally got the transaxle clean enough to shoot with alumi-blast. Very light coat of course!
Click to view attachmentIan, The tranny looks good. Could you describe your cleaning and degreasing method? Thanks.
Thanks.
When I dropped the motor this winter I noticed some pitting and areas where the alloy was exposed and unprotected. Dr Evil rebuilt my box last year and I wasn't about to pull it apart, so....
I read a bunch of threads (just googling 914world cleaning transmission) and the main takeaway was not to blast or power wash. Time for hand-to-hand combat!
First I used a small putty knife and a small screwdriver to dig out all the baked-on grease. Then I went over the whole transmission with a toothbrush dipped in mineral spirits. This got most of the grease off.
I covered up the vent hole with paper towel wrapped by electrical tape and used sandwich bags and zip ties to protect the hubs. I also took some 2 x 4's and screwed them to a dolly close together enough to support the transmission on its front end (all fluid was previously drained).
I wheeled the trans outside and sprayed two cans of brakleen on it, which got a lot more residue off. It also made it easy to see spots I missed with the screwdriver. More toothbrush and mineral spirits and then as a final "cleanse" I used marine-clean mixed 1:1 with hot water in a 1 gallon garden sprayer. A light rinse with plain water after that, being careful of the seals.
I dried it all off with compressed air, waited a day and masked off the stainless nuts and hubs with blue tape. Then sprayed a light coat of alumi-blast.
I'm really happy with how it came out. The only suggestion I'd make if you're gonna use this method is to put a tarp down when you shoot the brakleen...or better yet, suspend the dolly/transmission over a large plastic bin to catch the greasy mess. Brakleen isn't great for driveways either

Enjoy!
