Swivel Seal Assembly

4.7  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.  Make sure the water blasting system is shut-

down and the power system 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.

4.  Insert two 6-32 screws into the brass back-up 

ring. Tighten the screws evenly to push the 

brass back-up ring out of the high pressure 

hose adapter.
