Series 98 Operation & Maintenance
Carefully lift and slide in the Barrel over the Piston Wear
Bands, Quad Seal and Adaptor O-ring and push it down on
to the Adaptor Plate.
Thread the Tie Rods into the Adaptor Plate, use thread lock
compound on the threads.
Lubricate the inside of the Barrel and slide in the End Cap,
aligning the ports on the Adaptor and the End Cap.
Apply a little anti-seize compound on tie rod threads and
fasten the assembly with Tie Rod Nuts to the recommended
torque (Refer to page 18 Bolting Torque Tables)
Lift the Module using lifting eye bolts threaded into the End
Cap and place it horizontally. Put back the Plug/Cover Plate
on the End Cap to test the module.
Apply 10-15 psi air pressure to ports alternately to check
for smooth stroking for 5-10 cycles and then raise to 80 psi
and hold the pressure to check for any leaks past the Piston,
through the Rod Seal and the Barrel O-rings.
Do a bubble test for piston seal leak and for other seals check
Leakage rate after hold down time shall not be much higher
than 1-2 bubbles per minute with a
1
4" ID tube.
Stroke the piston a few times to set the seals if leakage is
higher, and repeat the bubble test. If still not within the
limits, dismantle the module to examine the cause.
If no abnormalities are seen, the Module is ready for
assembly on the Torque Module.
