2. Remove the screw (38), and set screw plugs (36) from the bearing holder (37).
The bearing holder is removed by screwing two jacking screws (P/N: 84-01-
460) into the screw plug threads (36) and backing off. The o-ring (14), roller
bearing (31), and snap ring (40) can now be removed. The snap ring (32), o-
ring (33), seal lining (34), and lip seal ring (35) may also be removed for
inspection.
3. Using the special T-handle screw (P/N: 96-01-006), Figure 21, back out the
thrust ring (41), angular contact ball bearings (42), ball bearing holder (43)
and ejector disc (46). Inspect parts and replace if necessary. Figure 18
illustrates the large conveyor bearing and part removal procedure.
4. Item (44) shim is used to adjust axial clearance. None, one or more shims
may be found upon disassembly. You should reassemble using same number
and thickness shims as originally installed. When replacing a conveyor, shims
needed should be determined as shown in Diagram 9.
5.2.7 Assembly Large Conveyor Bearings
Assemble the parts in sequence as shown in Figure 21. Observe the following when
assembling.
Fill the ball bearing holder (43) with ball bearing grease before installing the angular
contact ball bearing (42) faces the gearbox. If the ball bearing holder (43) cannot be
pushed into its seat by hand, use a pipe for a drift and gently tap it in. Be sure the
bearing holder bottoms out.
The parts should be assembled in the bearing holder (37) in the following order.
a. Roller bearing outer race (31) with rollers.
b. Snap ring (40) facing roller bearing.
c. Lip seal ring (35) in seal lining (34). Be sure lip seal ring is turned
outward.
d. O-ring (33) in groove of seal lining (34).
e. Seal lining (34) in bearing holder (37).
f. Snap ring (32) facing seal lining.
g. O-ring (14) in groove of bearing holder (37).
Apply ball bearing grease to the sealing lip of the seal ring. Apply enough grease around the
seal lining so the annular space between the lip seal ring of the lining and the end piece (27)
will be filled with grease in final assembly.
