21. Screw the diaphragm clamp (3) into the LP module
body (8) until hand-tight. Install the spring adjuster (2) into
the diaphragm clamp. Use a 10mm hex bit socket and flex
wrench, to screw the spring adjuster into the diaphragm
clamp until it is flush with the top.
22. Secure the LP module torque tool (keyhole side up) into
the vise jaw inserts. Place the LP module body (8) into the
LP module torque tool.
CAUTION: The diaphragm clamp tool has three
connection points that engage the diaphragm
clamp, proper alignment is critical to avoid
damage. Make sure to apply steady pressure
and keep the tool centered when installing the
diaphragm clamp.
Connection
CAUTION: To avoid damaging the diaphragm clamp,
do not exceed 15 ft lb (20 Nm) of torque.
23 . Caref ully plac e t he
diaphragm clamp tool and
foot pound torque wrench
onto the diaphragm clamp
(3). Torque the diaphragm
clamp to a value of 15 ft lb
(20 Nm).
Points
24. Lubricate the threads of the HP module body (13). Screw
the LP module body (8) all the way down onto the HP module
body (13) until it stops. Loosen the LP module body 1/8 of a
turn until the safety wire holes line up.
25. Insert the open ends of the safety wire (36) into the holes
on the LP module body (8). Ratchet the safety wire back and
forth while pushing it through the holes. This motion bends
the wire, allowing it to pass through the holes in the LP / HP
module body (8 & 13). Pass enough wire through the holes
for the tapered pliers to grip. Straighten the ends of the safety
wire that has been passed through the holes.
NOTE: The safety wire in the service kit is pre-bent for
installation. The pre-bent side of the safety wire faces
away from the LP / HP module body during installation.
26. Grasp both ends of the safety wire (36) evenly at a
perpendicular angle with the tapered pliers. Pull the safety
wire through until the top is flush with the holes on the
LP module body (8).
