1.Remove the screws and disc clamping bars from the rotor coupling disc, and remove the rotor.

NOTE: earlier machines used three 0.31” thick clamping bars and later models use six 0.14” thick clamping bars arranged in three sets of two bars each.

If the rotor is to be replaced, remove the screws, rotor clamping ring and coupling disc from the rotor hub.

Replacing the Rotor

1.Whenever the rotor and stator are separated, it is highly recommended that a new bearing and tolerance ring be installed when the rotor and stator are reassembled.

2.Examine the rotor, coupling disc, clamping ring, clamping bars, screws, lock washers, and the engine flywheel. Make sure that all of the parts are clean and in good condition.

3.Install a new bearing on the rotor shaft.

4.Assemble the coupling disc and clamping ring to the rotor hub. The surface of the disc with the stamping burrs should be against the rotor hub. The side of the clamping ring with the radius should be placed against the coupling disc. See Figure F.29.

5.Insert the screws with lock washers and evenly tighten to a torque of 17 to 19 Ft-Lbs.

6.Lift the rotor assembly with the hoist and lifting straps and recheck the engine flywheel and coupling disk for anything that might prevent proper seating.

7.To attach the coupling disk to the engine fly- wheel, align the screw holes and insert the six screws, with lock washers, through the disc clamping bars and the coupling disc and into the engine flywheel.

8.Evenly tighten all the screws to a torque of 17 to 19 Ft-Lbs.
