Checking the vibration pressures
A too low charge pressure is an early indicator for a fault (leakage) in the closed vibration circuit (if travel
system is OK). The pump cannot be operated correctly.
A too low starting pressure is an indicator for extreme leaks in the closed circuit or a defective vibration
motor coupling.
A too high operating pressure is an indicator for damaged vibration bearings or overfilling of the vibration
bearing housing.
•
Connect 600 bar pressure gauges to the high pressure test ports
•
Connect a 60 bar pressure gauge to the charge pressure test port
•
Drive the drum on old rubber tires
•
Start the engine and run it with max. speed
•
Switch the vibration on and read the pressure gauges
Nominal values: charge pressure 25 +/- 1 bar
starting pressure 365 +/- 35 bar
operating pressure
low amplitude approx. 90 +/- 15 bar
high amplitude approx. 100 +/- 15 bar
