REMOVAL OF QUADRIVE
5 . Use a spanner wrench to apply torque through the high-
speed shaft keyway (Type J05 clockwise; Types J14 or
J25 counter-clockwise) to loosen the bushing nut .
WARNING
: Never use the prime mover to produce the
torque needed. This could result in severe personal
injury or damage to the equipment.
CAUTION
: To avoid damage to the drive or the removal
tool, DO NOT exceed the H.S. shaft torque values listed
in Table 3.
NOTE: The nut will rotate freely for approximately 180°
as it moves from the locked to the removal position .
Resistance will indicate that unseating is occurring .
Turn until the nut and bushing are completely free . Now,
prepare the drive for lifting by disconnecting the torque
arm at the drive end .
