2012 December 12: Acid wash engine and transmission cases (4.15 hours)

Updated: 

I soaked the crankcase, sump, timing chest cover, transmission case, and transmission rear cover in oxalic acid for 7 1⁄2 hours today. Overall, the cases turned out fantastic. I have a bit of work to do on the crankcase due to some shadowing, but overall I am thrilled. I even got all of the battery acid stains on the transmission case removed. Amazing!

I assembled the tranmission layshaft and placed the thrust washers on the front of the main shaft.

I cleaned the parts for the generator and distributor.

I tossed all the spokes and nipples in degreaser for the night.

Cleaned parts. Generally a very nice match amongst all the cast aluminum parts without the change in appearance that comes from blasting or using other acids that alter the color. Precisely the original look I was after.

Some shadowing I'll address with some more oxalic acid.
