FOLLOWER WHEEL INSTALLATION
Fig.7Followerwheelinstallation
A. Loosen either cartridge (11, 12) so that follower
wheel (4) has a small amount of play.
B. Position housing (1) on a work bench with
opening for cover facing up. Create temporary
legs with screws to hold housing.
C. Install shims (5) in housing (1). It is preferable to
install the same shims that were removed from
the housing during disassembly; if that is not
possible, use shims of equivalent thickness.
D. Insert follower wheel (4) down through opening of
housing (1).
E. Apply a bead of white silicone on the surface
where output bearing retainer (6) will rest.
F. Install output bearing retainer (6) with shims (2). It
is preferable to install the same shims that were
removed during disassembly; if that is not
possible, use shims of equivalent thickness.
G. Install and tighten capscrews (29a).
H. Tighten cartridges (11,12).
BEARING CARTRIDGE REASSEMBLY
A. Coat the outside of bearing and bore of the
bearing cartridges (11, 12) with anti-seize
lubricant.
B Using an arbor press, install bearing into bearing
cartridges (11, 12). The rounded edge of bearing
should be pressed into cartridge.
SETTING INPUT SHAFT/CAM
BEARING PRELOAD
Fig.8Settinginputshaft/cambearingpreload
A. Position housing (1) on a work bench with
opening for bottom cover facing up. Create
temporary legs with screws to hold housing.
B. Apply EXP 222 grease to bearings
(18, 19, 20 and 21).
C. Install first cartridge (11) into the same side and
position as disassembled. It is preferable to
install the same shims that were removed during
disassembly; if that is not possible, use shims of
equivalent thickness.
D. Install and tighten screws (29a).
E. Insert input shaft (15) into housing (1) so that
shaft orientation is the same as before
disassembly.
F. Apply EXP 222 grease in bearing.
G. Install second cartridge (12) in the same position
as disassembled. It is preferable to install the
same shims that were removed during
disassembly; if that is not possible, use shims of
equivalent thickness.
H. Install and tighten screws (29a).
I. Rotate shaft (15) and check preload. There should
be no endplay and a small amount of drag should
be felt from preloading bearings—add or remove
shims (14) as necessary to obtain this condition. In
rare instances, it may be necessary to machine the
cartridge if all shims have been removed and
endplay still exists.
NOTE: The same amount of shims should be added
or removed from both cartridges.
