Massey Ferguson 450S Excavator, first start in 20+ years. It runs! (Part 2)

First start of MF 450S excavator after 20+ years. We have taken the pump apart to check after we found out that it was stuck when we last tried to start the machine. 2 days later the pump was put in and after an hour it started for the first time (on diesel) in over 20 years. It seems that a lot of money was spent on the machine a couple of 1000 hours before it was put away, maybe that's why it was allowed to stand without being cut to pieces. Everything seems to be working, but still a few handles that are stuck. and then a hydraulic hose broke, and a pipe that sprung a leak to the left belt. part 3 is coming.
