Re: oil pump rebuild questions

arg, more good and bad news. The good news is I have another pump from my 327 which I will use.

I had actually bought an oil pump rebuild kit from Kanter, which is what I was doing here. The kit contained drive gear and shaft, driven gear (pictured earlier), a dowel for the gear that mates to the camshaft, and a new pressure spring.

Today I brought the new shaft and drive gear plus housing and camshaft interface gear to the machine shop at my job. (automotive transmission development) A 1/8 inch hole has to be drilled through the new shaft, and the dowel then goes thorugh the camshaft interface gear holding it to the shaft....My colleague in the machine shop drilled the shaft crooked (on a drill press!) So this new shaft is kaput.
I guess like fuel and water pumps, it pays to leave the rebuilding to the pros.

The piston however bad it looks is really smooth, and the bore also looks good, does not hang anywhere. By smooth I mean running a fingernail over it, I can feel no surface irregularities. Monday, Monday....

Going to paint my driveshaft now, I don't think I can mess that up too bad.
