Is the Komatsu pc50uu-1 a hydraulic machine?
I’ve got a 1993 Komatsu PC50UU-1 gray market machine. I’ve got the pdf manual for it. It’s got a hydraulic problem that I’ve been unable to figure out. This machine is a direct hydraulic machine, no electronics, solenoids, etc. in the hydraulic circuit. I believe it uses a gear pump.
Why does my Komatsu pc50uu-1 swing slow down?
The swing feels normal with no load, but slows down as the oil heats up and is weak. The blade does not drift. If I lift the front with the boom, then put the blade down, it will hold the machine up after I’ve lifted the boom. The 1500 psi reading is when either the blade or the swing is stalled.
Where are the screens on a Komatsu pilot pump?
Komatsu seems to like to put little screens in all their pilot fittings, there should be a screen on the outlet of your pilot pump or at its first valve in, as well as screens in all your pilot control pressure in lines. Theres also usually screens in the pilot lines into the control valve.
What are the control valves on a Komatsu pump?
There are two control valves that operate all of the functions. One is a 6 spool valve and one is a 3 spool valve. The first two stages of the pump feed the 6 spool valve, and all functions seem to work as they should. The third stage of the pump feeds the 3 spool valve. this valve controls the blade, the swing motor and the rapid travel function.

Where to find Komatsu construction machine serial number?
N.B.: In the manufacturer Komatsu’s own internal database, construction machines are normally only listed under their serial numbers (the last 6 digits of the 17-character VIN) and the corresponding type designation. (provide the (identification) number of the corresponding component and its type designation)
How many digits are on a Komatsu Vin?
The manufacturer Komatsu also uses Certificates of Conformity in which merely the last 6 digits (serial number) of the VIN are listed, although the complete 17-character VIN may be stamped onto a given machine. This may at times lead to a negative trace even if that particular machine has been reported as stolen.
