7. Pry seal from carrier frame. Discard seal. Remove
lower bearing cone from frame.
8. Inspect bearing cups in carrier frame for wear or
damage. If bearing cups are damaged, remove bearing
cups from frame and replace.
9. If necessary, remove spacers, seals and bearings
from castor wheel using Figure 15 as a guide. Inspect
and replace all wheel components that show signs of
wear or damage.
Assembly (Fig. 13)
1. If components were removed from castor wheel, as-
semble castor wheel (Fig. 15):
A. Press bearing cups into castor wheel until they
are flush with shoulder in wheel.
B. Install grease packed bearing cone into wheel.
C. Install seals into wheel.
D. Carefully fit bearing spacers and then castor
spacer into wheel.
2. If bearing cups were removed from carrier frame,
press new cups into carrier frame until they are flush with
shoulder in frame.
3. Pack both bearing cones with new grease. Place
grease packed bearing cone into lower bearing cup of
carrier frame. Install new seal.
4. Slide castor fork up through carrier frame taking care
to not damage seal. Position grease packed bearing
cone onto castor fork. Place three (3) belleville washers
onto castor fork noting orientation shown in Figure 14.
IMPORTANT: After correctly tightening the lock nut
that secures castor fork to carrier frame, it should
take from 65 to 75 in- lb (7.3 to 8.5 N- m) to rotate the
castor fork.
5. Install lock nut onto castor fork. Tighten lock nut until
castor fork requires from 65 to 75 in- lb (7.3 to 8.5 N- m)
to rotate.
6. Remove plug (item 12) from carrier frame. Using
grease gun through plug hole in frame, fill area sur-
rounding the castor fork shaft with grease. Allow grease
to fill cavities below lower bearing, between bearings
and above upper bearing. Reinstall plug into frame.
NOTE: Periodic greasing of castor fork bearing area is
not necessary. Do not replace plug (item 12) with grease
fitting. Grease cap (item 1) will loosen if castor fork has
excessive grease installed.
7. Install new grease cap (item 1) so cap shoulder is
flush with top of carrier frame. There should be no evi-
dence that the cap is indented by top of castor fork.
8. Position castor wheel to castor fork and secure with
cap screw and lock nut.
9. Lower machine to ground.
1. Lock nut
2. Belleville washer
3. Upper bearing cone
