6. Using a suitable drift punch, drive the two bearing
cups out of the hub. The inner bearing cup is
removed from the outer end of the hub and the
outer bearing cup from the inner end of the hub
(see below).
7. Remove all old grease and wash parts in a
petroleum based solvent.
8. Check the bearing rollers individually by rotating
each roller in turn, checking the entire surface area
for wear or pitting.
9. Inspect the entire area of the outer cup for wear or
pitting.
IMPORTANT:
Individual parts of the bearings should
not be replaced separately. If any part of a bearing is
faulty, the complete bearing must be replaced.
10.Check the threads on the end of the axle. Clean up
thread with a die nut if necessary.
Reassemble and Install Hub
1. Press the two hub bearing cups into position in the
hub so that the tapers are opposed to each other,
ensuring that they are completely seated.
2. DO NOT pack the space in the hub between the
two bearings with grease. Pack the grease into the
rollers of the inner bearing cone assembly and
place it in position in the hub.
3. Place a new grease retaining seal on the inner end
of the hub and tap it into position. Apply a smear of
grease around the lip of the seal.
4. Pack wheel bearing grease into the outer cone and
rollers of the outer hub bearing. Place the hub
assembly on the axle and position the inner cone
and rollers assembly in the outer end of the hub.
5. Fit slotted nut on the stub axle.
6. While rotating the hub, tighten the nut to a torque of
25 ft/lb (33.8 Nm).
7. Back off the adjusting nut 1/2 turn.
8. Retighten the adjusting nut to 10 - 15 in/lb with
torque wrench.
9. Position hole in axle nut on the nearest hole in
axle.
10.Install split pin and replace the grease retaining
cap.
NOTE:
The slotted nut lock must be selectively posi-
tioned to line up with the split pin hole.
11.Replace wheels. Torque nuts to 60-70 ft./lbs (81-95
Nm) in pattern shown below.
CHECK WHEEL NUTS
Check the wheel nuts for proper torque after the first 8
hours of operation and every 100 hours thereafter.
Torque to 60-70 ft/lbs (81-95 Nm) in pattern shown in
Hub Installation.
GREASE CHASSIS
Grease all pivot joints after the first 8 hours of
operation, then every 25 operating hours with general
purpose grease. Grease every 8 hours when operating
conditions are extremely dusty or sandy, or
immediately after every washing.
Locations to grease (see following three photos):
1. top leveling link (2)
2. lift arms (4)
3. crowding cylinder (2)
4. attachment mounting plate (1)
5. lift arm cylinder (2)
