Since I'm finally bringing this thread up to date I also got started on the crank for the 357 going in the Malibu.
In this pic the crank is set up in a machine that will slowly rotate the crank. I took the pic after I started cleaning one of the bearing surfaces so you could see the difference after a little cleaning. The crank had been left standing with no protective oil on it and started to rust. Totaly my fault, I just forgot about it the past couple years because I was busy with other things and it's humid where I live.
In this pic the machine with the belt on it is used for cleaning, sanding, and polishing the bearing surfaces. In the pic there's a velcro belt on and I'm using it to clean the rust off the surfaces.
This pic shows an oiling hole I've chamfered with a grinding stone to provide better oiling to the bearings. Since the oiling holes are on an angle, the hole is opened up a little on the side the oil is coming from to provide that side of the bearing better lubrication. The chamfered edges will be rounded a little more with a very small round file by hand to smooth the sharp edges before more work is done to the crank.
