DISASSEMBLY / ASSEMBLY (cont...)
7.3. ASSEMBLY OF MOTOR
y Check for any burrs that may have resulted from the disassembly of the motor.
Stone off surfaces with a medium grit carborundum stone.
y Insert new Ring Seal and Bearing into Shaft End Cover. Next install Teflon Seal and
Thrust Plate.
y Insert the Matched Gear Set, making sure they are assembled the same way as
they were disassembled.
y Insert the new greased Gasket Seals into the grooves on both sides of the Gear
Housing.
y Slide the Gear Housing over the Gear Set and tap gently into position with a soft
hammer. Double check "Index Stamped Numbers" for correct alignment.
y Insert new Ring Seal, Bearings, Teflon Seals and Thrust Plate into Port End Cover
and tap lightly into place, using a soft hammer.
y Finally, lubricate the 8 Capscrews and thread them (with hardened washers) into the
Motor Adapter and snug up in diagonally opposite sequence. Rotate the Winch Shaft
with a 6" wrench to make sure there is no binding in the motor.
y After the fasteners are tight and you are sure there is no internal binding, torque
diagonally opposite Fasteners to 150-170 lb. ft.
7.4. DISASSEMBLY OF BRAKE
Following removal of the Brake, proceed as follows:
y Remove Sun Gear Shaft complete with Ball Bearing, Brake Hub and Sprag
Assembly.
Three 1/2-13NC tapped holes are provided in the Brake Piston to facilitate easy
removal.
y Friction and Divider Plates and Spacer Ring can now be removed from the Housing.
Be sure to note orientation of Sprag Clutch prior to disassembly. This is determined
by the direction of relative rotation between the Brake Hub and Sun Gear Shaft that
causes either freewheel action or lock-up of the two parts.
y To remove the Brake Hub, Sprag Clutch Assembly and the two Sprag Bearings from
the Sun Gear Shaft, the Retaining Ring must first be removed. The Ball Bearing can
now be removed if required.
