8.   With  a  valve  puller  remove 

the valve seat (37) and o-ring 

(38) replace if worn. If exces-

sive pitting is seen, replace 

the worn parts. Check valve 

seat o-ring (38) for wear and 

replace as necessary.

9.  Remove the spacer (39A), pressure spring (33), support ring (32 

or 31A for SP100HK), v-sleeve (31), and pressure ring (30), from 

the manifold (29) and check for wear.

   

 

10.   

With  a flat headed screw-

driver remove the weep return 

plate (48). Remove the o-ring 

(49) and check for wear.

12. 

Inspect ceramic plunger 

(24A) tips for wear.  If neces-

sary, replacement of the 

ceramic plungers may be ac

-

complished by removing the 

plunger bolt assemblies (24) 

with a 13mm wrench.  Ce-

ramic plungers should now 

slide off the stainless steel 

plunger base (22).  Exces-

sive resistance to plunger 

removal may be overcome 

by heating the stainless steel 

plunger base.  This will melt 

any excess loc-tite beneath 

the ceramic plunger allowing 

easy removal.
