Replacement

12.Carefully mount the rotor onto the generator shaft. Install a new sleeve collar (part num- ber T14337), washer, and rotor locking nut.

NOTE: Be careful not to damage or deform the new sleeve collar. Carefully tap the new sleeve collar into position. The rotor locking nut should be torqued to 175 ft.-lbs.

After the rotor locking nut is properly torqued, bend the washer down over the locking nut.

Check rotor air gap. .017" minimum is allowed.

13.Mount the brush holder assembly to the sta- tor frame using two bolts, washers, and nuts.

Installing and Seating Exciter Slip Ring Brushes

a.Make sure the slip rings are clean and free from oil and grease.

b.Spacing between the brush holder and slip rings must be .050" to .090". Adjust as required.

c.Before placing the exciter brushes in their holders, twist the brush pigtail at its entrance to the brush until the strands are tightly packed and no part of the pigtail protrudes beyond the brush surface in the pigtail slot. When the brush is placed in the holder, clear the pigtail from the side of the holder to allow free radial move- ment of the brush.

d.The exciter brush spring must lie flat on the corner of the brush and not touch either side of the retainer.

e.With the brushes in place, insert one end of a minimum 24" long piece of 180 grit sandpaper between the slip rings and brushes (abrasive against brushes). With slight additional finger pressure on top of brushes, pull the paper around the cir- cumference of the rings in the direction of rotation only. Repeat this procedure until the entire face of the brush is contoured to the radius of the slip ring.

f.Check the brushes to be certain that there is spring tension holding them firmly against the slip rings.

14.Install the alternator cover with the screw and washer at top and the screws at the two sides.

15.Install the panel below the control panel on the case front.

16.Connect the negative battery cable.

17.Close and latch left and right side case doors.
