10 Things to Consider When Buying komatsu pc200-7 hydraulic pump

The pump you show is the last series of units I worked on and they gave the fewest problems. They are very easy to rebuild if you can get parts which most Komatsu dealers would supply. The control parts are cartridges which are easy to change and set up. The older units had block section controls that bolted onto the side of the pump and could be a nightmare when things got worn. There were spools and seals everywhere and any leakage made adjusting the system real time consuming.

As to who makes the pump I'm not sure anymore. I'm pretty sure that neither KYB or Kawasaki manufacture that unit. I can say that no one else puts out a pump that looks like that for any other excavator I've had my hands on and I've been into most everything now. I can say that no KYB, or Kawasaki unit that I've ever worked with would work in a Komatsu excavator. The hydraulic and electronic controls systems are just far too different to be able to marry into this system.

Over the years I've had to deal with plenty of people selling aftermarket parts and would warn anyone considering using them to get your warranties with the whys and wherefores in writing before using them. More than once I've had 20 hour shotgun failures where the supplier cried contaminated oil caused the wreck.
