Step 11
Run the Thru-Shaft Motor Without Water
Pressure, Then Under Full Water Pressure.
Remove all tools and materials from the hog head
and raise it to the full up position.
Activate the hydraulic system and run the thru-
shaft motor at maximum rpm for 15 minutes.
Make sure not to apply water pressure dur-
ing this step.
Running motor without water pressure will fully
test the thru-shaft motor operation and allow the
bearings and seals to work themselves in. If the
spray bar does not turn initially, use a 2’ piece of
wood or a broom handle to rotate the spray head
counterclockwise to get it started. Figure 19.
If the thru-shaft motor is assembled properly, it
will start on its own each time it is activated from
this point forward. If it continues to stall on start
up, contact Hog Technologies Customer Service
for assistance.
Once the initial run up is complete and with the
spray head still turning at maximum rpm, make
sure all personnel are well clear of the spray head
and apply full water pressure. Run the thru-shaft
motor for another 15 minutes. Figure 20.
When testing is complete and with the unit still
running at maximum pressure, check the weep
holes in the thrust housing cap just below the high
pressure hose connection for water leakage. If
water is dripping from the holes, the swivel seal
in the hose fitting will need to be changed. If no
water is dripping from the weep holes and the
spray bar is still rotating at maximum rpm, your
unit is ready to be put back into service. Figure 21.
