4.2.6

While supporting the cylinder, loosen the
locknuts (18) ONE TURN AT TIME and in an
alternating (crossw ise) pattern until the spring
force is completely relieved. Remove the
locknuts and w ashers (17). Mark all of the
w ater outlet ports for identification. Deep w ell
sockets are required. See table 9 for size and
depth of socket required.

4.2.7

Using lifting equipment, carefully remove the
cylinder (19) and piston (33) as an assembly.
Set aside in a clean area.

Note: If a stud (6) should happen to come
loose, remove it completely, clean the threads
on the stud and the threads in the mounting
flange. Apply Locquic

Primer Grade " T" to the

stud threads. After the threads have dried,
assemble to the mounting flange using Loctite

#262. The end of the stud must not extend
past the mounting surface of the mounting
flange.

Loctite

#262 must be shaken prior to

application.

Loctite

#262 may irritate sensitive skin.

Refer to the product label for proper
safety precautions.

4.2.8

4.2.17

While supporting the w eight of the
cylinder/piston assembly, tighten the locknuts,
ONE TURN AT A TIME and in an alternating
(crossw ise) pattern until the cylinder is seated
