Generously apply grease (MOBILITH SHC 007) to teeth of ring gear (item #26), teeth of planet gears in drum (item

#1), and to bushing (item #12) in gear housing end bearing. Apply a small amount of grease to base of bushing
(item #13) on motor end bearing. Apply grease to teeth of output sun gear (item #7) and input shaft (item #10).
Place end of shaft with output sun gear on it into drum (item #2). Rotate shaft to engage planet gears with output

sun gear. Place Gear End Bearing on Drum and engage planet gears with ring gear.

Assemble motor end bearing (item #8) to drum assembly and use tie plates (items #11) and capscrews (items #15)

to hold both end bearings together. Tighten capscrews to 55 ft-lbs (75 Nm).

If necessary, remove and replace the shifter assembly (manual, item #2, or air-cylinder, item #3), as follows:
MANUAL CLUTCH SHIFTER ASSEMBLY
Loosen setscrew (item #19) and jam nut, then unscrew shifter assembly (item #2). Be sure slot in ring gear is not

aligned with clutch shifter hole. Rotate drum, if necessary, to ensure hole and slot are not aligned

Reinstall shifter assembly with plunger, jam nut, and handle positioned in gear housing as shown below. Thread as-

sembly (with handle engaged in cylinder slot) into the gear housing. Pull drum toward the gear end bearing housing to
remove play. Hold drum in position and continue threading the shifter assembly in until the gap between the end of the
handle and cylinder is 7/16 +0 -1/16 inch and handle is in the horizontal position (see below). Note: This gap will
vary with drum endplay. With the drum pulled against the motor end housing, the gap should be 3/8 inch.

Lightly tighten jam nut. Rotate drum until handle snaps fully into the engaged position. Pull handle out and rotate 90°.

Verify that drum can be rotated freely (at least one full revolution) with clutch shifter at the DISENGAGED position. Se-
curely tighten jam nut while holding the handle. Tighten setscrew (item #19) securely. Re-check clutch operation as
described on page 5.
