The hollow shaft has tolerance H7. Lift thereducer in the, for this purpose, suitable hole J11-72 andJ100-190 in the torque arm holes or enclosed lifting ears.Grease shaft with Molykote BR2 or corresponding beforemounting the speed reducer. The speed reducer must notbe forced onto the shaft.2. When fitting the V-belt pulley use screw to press it intoposition (tapped hole at input shaft is not standard on typeJ 11-32).
