BELL CUP INSTALLATION
(ALL)
Ensure that shaft taper and threads are clean
before installing a bell cup. Also, make sure that
the threads and taper on the bell cup are clean.
Place one (1) RPM-419 wrench on the flats of
the turbine spindle. Use another RPM-419 with
a torque wrench fitted into the 3/8" square of the
wrench. Hold the shaft while applying pressure to
the torque wrench in a clockwise direction. Tighten
bell cup onto the turbine shaft to a final torque of
50-70 lbs•in (5.65-7.91 Nm).

Failure to tighten the bell cup in place
may cause vibration of the applicator and/
or premature turbine failure.
Figure 28: Effective Length Torque Wrench
Example: A desired true torque is desired using a
9-inch effective length torque wrench. Wrench
offset is 1 3/4-inches (1.75-inches).
L = 9-inches
TT = 50 lbs•in
E = 1 3/4-inches
DR is dial reading.
DR = 50 (9) DR = 42 lbs•in
(9 + 1.75)
CCV VALVE
CONFIGURATIONS AND
INSTALLATION
1. If RPM-415 one valve assembly is used, screw
the spanner nut of the valve into the inlet of the
manifold (hand tight).
2. If RPM-408, -409, or -416 valve assemblies
are used, install RPM-61 insert into manifold first.
Tighten spanner nut (hand tight) then tighten per
step #3.
3. It is recommended to leave the valve assembly
hand tight until all air and fluid connection are
made to the rear manifold and to the valves
before tightening the spanner nut, in case the
valve assemblies need to be rotated for clearance
purposes. After all connnections are made, tighten
spanner nut with CCV-7 spanner tool 1/8-1/4 turn
more after valve is seated. You may also tighten
the valve assemblies using a torque wrench fitted
with an adapter for the 1 1/16" spanner nut. Torque
to 132-156 lbs•in (14.9-17.6 Nm).
