H . BRAK E SECT I ON ASSEM BLY
1. Lubricate and install inner piston (item 17) into
brake housing (item 14).
2. Insert sliding clutch (item 27) into bore of inner
piston (item 17) with long side down.
3. Install thrust washer (item 48), then clutch
spring (item 47).
4. Insert the middle piston (item 21). While
holding down on piston (item 21) install
retaining ring (item 24)
5. Insert the brake driver/clutch assembly,
making sure that it engages the sliding clutch
(item 27).
6. Install the stator plates (item25) and friction
discs (item 26) starting with a stator plate and
alternating between friction discs and stator
plates. There is one more stator plate than
friction discs so you should end with a stator
plate. Note: Soak friction discs in hydraulic oil
before installation.
7. Inspect each new seal (item 51) to make sure
it has an o-ring in the groove of the seal.
Install one seal into the bore of the brake
housing (item 14) with the o-ring side toward
the brake pack. Place the other seal onto the
brake piston (item 29) with the o-ring side
toward the flange of the piston.
8. Lubricate and install piston into the brake
housing and gently tap down until seated.
9. Install the springs (item 30) into the spring
pockets. If working in a horizontal position,
coat the bottom of each spring with chassis
lube to keep it in position.
10. Install the brake cover (item 28) onto the brake
housing and tighten capscrews (item 49)
evenly, alternating between opposite
capscrews. Make sure ports are oriented in
proper position.
11. Check the brake release with a portable
hydraulic pump. Full release should be
obtained at 320-340 psi. Also, check the
brake for proper operation by applying 280 psi
to the brake port and adapting a torque
wrench to the input shaft. The torque in the
payout direction should be 95-115 ft-lbs.
12. Check the air operated clutch by applying 100
psi. air to “Clutch In” and “Clutch Out” ports.
Check for leaks and proper working of clutch.
