3.5 RE-ALIGNING TORQUE HUB INPUT
COUPLING
The following procedure applies to torque hubs with inte-
gral brakes.
Equipment Required
1. Hydraulic power supply (hand pump) capable of
producing 200 psi (13.8 bar).
2. Hydraulic fittings to adapt hydraulic supply to brake
release port on hub.
Procedure
1. Using appropriate fittings, connect a line from the
hydraulic power supply to the brake port.
2. Pressurize the brake release port 155 to 200 psi
(10.6 to 13.8 bar) to release the brake.
3. Verify that the brake is released by rotating the input
coupling or hub spindle.
4. Once the brake is released, the input coupling will
be free to re-align with the drive motor.
5. Install the drive motor on the hub, then release the
hydraulic pressure at the brake release port. The
coupling will remain in position.
6. Disconnect the hydraulic power supply and recon-
nect the line going into the brake release port.
