Bottom Roller Bearing: Left Side
1. Remove the bottom bearing on the right side from
the frame.
2. Remove the drive chain. Then remove the sprocket
by removing the cotter pin, slotted hex nut, and
washers.
NOTE: Have the roller blocked up or supported.
3. The protective collar on the bearing should now be
loose so you can pull the roller out of the bearing.
Loosen the bolt from bearing clamp which holds the
cartridge bearing in place on back side of chain case.
Remove the bearing and the O-ring.
4. To replace, reverse the order. Be sure all parts and
wear surfaces are thoroughly clean and in good
condition. Be sure the O-ring is also in good condition.
5. When replacing the left bearing, first put the O-
ring on the bearing. If the O-ring will not stay on the
bearing long enough to set the bearing in place, put a
little heavy grease on the O-ring. Now push the bearing
in and apply moderate pressure on the bearing so the
O-ring will seat and spread slightly thus keeping the
oil in the chain case from escaping through the bearing.
6. Re-install sprocket and chain. Fill chain case with
1.5 pints of 85W 140 wt. lube. Rotate roller and watch
for any interference between roller and frame.
Top Roller Bearing Slide: Left side (Figure 6)
1. To replace the bearing or quad seal, remove the
RTU bearing holder on the right side. Remove the
drive chain. Then remove the sprocket by removing
the cotter pin, slotted hex nut, and washers.
2. Remove the three hex head bolts holding the front
slide bar (15) being careful not to damage the brass
shims between the slide bar and the chain case.
Remove the two hex head bolts holding the rear slide
bar. Now the roller, the bearing, and bearing slide can
be removed.
3. To replace, reverse the order. Be sure all parts and
wear surfaces are clean and in good condition. Be
sure the quad ring seal is also in good condition. When
replacing, put a little grease on the quad ring seal, on
the surface it slides against, and on the slide bars.
Replace the shim stock and tighten the three hex head
bolts.
Position rear slide bar up against bearing slide, add
the two bolts, apply moderate pressure against the
bearing slide and tighten the bolts. The bearing slide
should be moderately difficult to move up and down.
Add or remove shims as needed.
GENERAL BEARING REPLACEMENT
INSTRUCTIONS:
-IMPORTANT NOTICE-
Replacement bearings should be only high quality
original equipment bearings for longer life.
Install new complete bearing housing if needed or just
replace the bearing insert.
The shafts should be straight, free of burrs and up to
size. If shaft is worn, replace or have the shaft built
up to standard prior to completing assembly.
-IMPORTANT NOTICE-
Bolt the bearing housing tightly to the frame and then
lock bearing to the shaft as follows: Lock bearing to
shaft by rotating the eccentric collar in the direction of
the shaft rotation. Rotation is clockwise for both rollers
when standing at the chain case. Use a punch and tap
the collar tight torquing the set screw on shaft to 70
inch pounds. Use a good grade of thread lock on the
set screws.
MAINTENANCE
Protective Collars
The special protective collars protect bearings from
vine and wire wrap, and dirt buildup next to the bearing
seal. The protector locks onto the shaft which rotates
within a close clearance from the outer race of the
bearing. Grease coming from the bearing oozes into
the protecting collar, keeping dust and particles from
entering the seal area, increasing the bearing life.
