6.
After the bedknife has been ground and is true,
adjust the reel, roller, and wheel bearing; refer to
Adjusting the Reel, Roller, and Wheel Bearing
(page 14)
.
Adjusting the Reel, Roller,
and Wheel Bearing
After the initial 30 operating hours, check the reel
bearing, roller bearing, and wheel bearing. Thereafter,
check these parts every 200 to 250 operating hours.
If necessary, adjust the reel bearing. If necessary,
adjust the roller bearing. If necessary, adjust the
wheel bearing.
Servicing the Roller
Disassembling the Roller
1.
Remove the brackets and washers from each
end of the roller and inspect the bushings.
2.
Remove elastic stop nut.
Note:
After the elastic stop nut has been
removed, slide the sleeve off the roller shaft.
Point the end of roller downward into a container,
at the same time pulling the roller shaft out,
allowing lubricant to drain from the roller.
3.
If the roller shaft is to be replaced, remove the
double jam nuts.
4.
Remove the remaining sleeve and seals from
both ends of the roller.
5.
Remove the bearing cones from each end of the
roller.
6.
Remove the bearing cups with caution.
7.
Remove the inner seals by using a seal remover.
Assembling the Roller
1.
Lightly oil the lips of the inner seals. Install the
inner seals on each end of the roller, making
sure that the garter springs face inboard.
2.
Replace the bearing cups and insert the bearing
cones into the roller.
3.
Lightly oil the lips of the outer seals. Install the
outer seals on each end of the roller, making
sure that the garter springs face inboard.
4.
Slide 1 sleeve onto the roller shaft against the
double jam nuts.
5.
Wrap the threaded area of the roller shaft
with cellophane tape to protect the seals, and
carefully slide the shaft through the right side
of the roller. Slide the roller shaft into the roller
until it penetrates the inner most oil seal on the
right side.
6.
Pour approximately 0.5 L (16 fl oz) of SAE 90 or
140 gear oil into the roller housing.
7.
After the oil has been added, carefully push the
roller shaft through the entire roller assembly.
Remove the cellophane tape.
8.
Install the sleeve onto the roller shaft and slide
up against the bearing cone.
9.
Install the elastic stop nut and secure it by
holding the double jam nuts. Tighten the elastic
stop nut.
Note:
Tighten the elastic stop nut until all axial
and radial motion has been removed from the
roller shaft and bearings. Ensure that the roller
rotates freely on the shaft.
10.
Grease the bearings with heavy duty No. 2
wheel bearing grease.
11.
Install the washers and install the left and right
bracket and the bushing assemblies.
Important:
After the cutting unit has been
completely assembled, perform the following
critical adjustments:
A.
Check the reel bearings and the fasteners.
B.
Set the height of cut.
C.
Adjust the bedknife to the reel.
