Generously apply grease (MOBILITH SHC 007) to teeth of ring gear (item #6), teeth of planet gears in drum
(item #1) and to bushing in end bearings (item #7 & #8). Apply grease to teeth of gear (item #5) and to
splines of shaft (item #12). Place splined end of shaft into splines of hub in brake housing end bearing (item
#8). Place drum over shaft and rotate drum to engage planet gears with output gear on shaft and ring gear in
end bearing.
Assemble end bearing to drum assembly and use tie plates (item #13) and capscrews (item #18) to hold both
end bearings together. Tighten capscrews to 106 Ft. Lbs. (144 Nm.). If necessary, remove and replace
appropriate shifter assembly (item #2 or #3), as follows:
MANUAL CLUTCH SHIFTER ASSEMBLY
Remove by loosening setscrew (item #25), jam nut and unscrewing clutch shifter. Be sure slot in ring gear is
NOT aligned with clutch shifter hole. Rotate drum, if necessary, to insure holes are not aligned. Reinstall
clutch shifter with plunger, jam nut and handle positioned in cylinder housing, as shown. Thread assembly
(with handle engaged in cylinder slot) into the end bearing. Pull drum toward the brake housing end bearing
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”
and handle is in the horizontal position, as shown below.
NOTE: This gap will vary with drum endplay. With the drum pulled against the gear housing, the gap should
be 7/16 inch. Lightly tighten jam nut. Rotate drum until handle snaps fully into the engaged position. Pull
handle out and rotate 90o. Verify that drum can be rotated freely (at least one full revolution) with clutch
shifter at DISENGEGED position. Securely tighten jam nut while holding the handle. Tighten setscrew
securely. Re-check clutch operation as described on page 5.
AIR CYLINDER SHIFTER ASSEMBLY
Remove by loosening setscrew (item #25), jam nut and unscrewing clutch shifter. To reinstall, thread air
cylinder into housing. Install one or two shims (item #49) under cylinder head, if needed, to orient air cylinder
port for pneumatic connections. Tighten setscrew. Refer to page 5 and check for proper operation of the
clutch.
BLOCKED CLUTCH
Insert plunger assembly into gear housing bore so it engages into ring gear slot. Pull drum flange toward gear
housing and thread setscrew into housing until it bottoms out and drum starts to move. Back setscrew out 1/2
turn and lock in place with jam nut.
