Crankcase Oil Drain Valve & Hose
WARNING
OPERATING THE PUMP LOW ON OIL WILL CAUSE SEVERE
DAMAGE TO THE POWER END OF THE PUMP.
UNDER NO CIRCUMSTANCES SHOULD YOU RUN THE PUMP
IF THERE IS NO OIL SHOWING IN THE SIGHT GAUGE.
Changing Crankcase Oil
The crankcase is filled with 80w90 high grade non
detergent gear oil that is a high viscosity and flows
slowly at room temperature or below. Since many
crankcases hold up to 5 gallons (19 liters) of oil, it
is best to operate the pump long enough to raise
the temperature of the oil to normal operating
temperature before draining the oil.
Draining the crankcase oil:
1. Make sure the water blasting system is shut-
down with the truck in the service position.
2. Remove the safety plug at the oil drain ball
valve fitting.
3. Attach a drain hose to the ball valve fitting
and route the hose to a suitable waste oil con-
tainer capable of handling at least 6 gallons
(23 liters) of oil.
4. Open the drain valve and drain the oil.
5. When draining is complete, close the valve and
insert the safety plug. Make sure the safety
plug is clean to avoid contamination. Tighten
the plug to specifications.
6. Wipe up any spilled oil and properly dispose
of the waste oil and oil soaked rags.
