Cat hydrostatic transmission overhaul.

Over the next few days, I've got the job of overhauling a Cat 953B HPCU. The 943, 953, 963 and 973 B series and earlier are all much the same.

Anyway, due to the fact that these machines are getting scarce in front line work nowadays, and the relatively high cost of repair I think this may be the last one I ever get to do.

If anyone has any interest, I'll post some photos showing the the insides of one of these mystery boxes and what goes into rebuilding them.
