Troubleshooting: Piston Disassembly and Cleaning
E
Re-assemble the piston assembly. Push the
mechanism up and down several times to
make sure the piston moves smoothly and
consistently. If it is not consistent, repeat
Step D until it moves freely, or replace.
Contact your Bradley representative to order
the Piston & Liner Kit (S65-172).

Using a 15/16" socket wrench,
loosen the liner from the valve body
and lift out with a needle nose pliers.
C
Using a 1/2 deep socket wrench,
loosen the upper seat from the liner
and lift out parts with a needle nose
pliers.
D
Disassemble and clean the piston
assembly parts with any cleaner suitable
for brass and stainless steel. (If necessary,
use a 400-grit sandpaper to polish and
hone the piston and liner.)
