4" Motors:
15 to 20 ft-lb. (20 to 27 N-m)
6" Motors:
50 to 60 ft-lb. (68 to 81 N-m)
8" Motors with 1-3/16" to 1-5/8" Jam Nut:
50 to 60 ft-lb. (68 to 81 N-m)
8" Motors with 4 Screw Clamp Plate:
Apply increasing torque to the screws equally in a criss-cross
pattern until 80 to 90 in-lb. (9.0 to 10.2 N-m) is reached.
Jam nut tightening torques recommended for field assembly
are shown. Rubber compression set within the first few hours
after assembly may reduce the jam nut torque. This is a normal
condition which does not indicate reduced seal effectiveness.
Retightening is not required, but is permissible and recommended
if original torque was questionable.
A motor lead assembly should not be reused. A new lead assembly
should be used whenever one is removed from the motor, because
rubber set and possible damage from removal may prevent proper
resealing of the old lead.
All motors returned for warranty consideration must have
the lead returned with the motor.
