Rotating/Replacing Drum Bearings
67
Important:
Be sure to note the sequence of parts used for the rear drum indicator assembly. Also, when
reinstalling, do not over-tighten the nut that holds the indicator in place (
See Exploded View, Page 43)
.
Bearing Replacement (Right Side):
If the left (outboard) bearings are the only ones that need changing, proceed to reassemble the unit. You can check
the drums at this point by lowering the conveyor bed and spinning the drums by hand. This will help determine if the
inboard bearing(s) need to be changed to eliminate noise or excessive play in the drum.
1.)
With the drums resting on the conveyor bed, proceed as follows. Remove the 4-four 3/8" x 1 x 1/4" bolts from
the drum support casting on the right side, remove the on/off switch and depth gauge with the bolts.
2.)
Remove the upper two 3/8" x 1 1/4" bolts from the drum support casting on the left (outboard) side of the sander.
Loosen the bottom two 3/8" x 1 1/4" bolts from the left drum support casting, but do not remove them.
3.) (Cont’d.)
Lift the right (inboard) side of drums and place a 2 x 6 on edge under the drums. Loosen and remove
the V-belt pulleys from drum shafts
(See Figure 39)
.
Important:
Make sure to note the location of the pulleys. Also measure the distance from pulley edge to the drum
support casting to use as a reference when reinstalling pulleys so they will be properly aligned.
