General Maintenance
4.10 Swivel Seal Replacement
The swivel seal must be inspected at the start of
each shift and replaced at the first sign of leakage
to avoid damage to the swivel nut and thru-shaft
cover housing. Swivel seal leakage is indicated by
water dripping from the weep holes in the housing
just below the swivel nut.
Use the following procedure to replace
the seal:
1. Lower the Hog Arm and blasting head to the
pavement.
1. Make sure the water blasting system is shut-
down and the truck is in the service position.
2. Loosen the swivel nut on the top of the thru-
shaft motor. Be sure to pull the hose and
adapter straight up so you don’t bend the
swivel tit inside the fitting.
3. Rotate the end of the high pressure hose
toward you until the swivel seal adapter is
visible.
