Planetary Wheel Drive Assembly (Fig. 15)
NOTE: Use new seal kit when assembling planetary
wheel drive.
1. Clean parts in solvent. Inspect parts for damage or
excessive wear and replace as necessary.
2. Install oil seal (3) to spindle (1).
3. Press bearing cups (5 and 11) into housing (9).
4. Press bearing cone (4) onto spindle (1).
5. Install boot seal (2) to housing (9). Assemble hous-
ing (9) to spindle (1).
6. Press bearing cone (12) onto spindle and secure
with bearing shim (14) and snap ring (15).
7. Install o–ring (13), then secure ring gear (16) to
housing (9) with socket head screws (7) and lock wash-
ers (8). Torque screws from 118 to 144 in–lb (13.3 to
16.3 N–m).
8. Install secondary carrier (28), secondary gear (27),
and primary carrier (26).
9. Install drive shaft (25) and primary gear (24). Secure
gear with retaining ring (23).
10.Make sure that thrust plug (21) and thrust washer
(22) are captive on inside of end cap. Install o–ring (20)
and end cap (19). Secure end cap with retaining ring
(17).
11. Check operation of planetary wheel drive before
installing assembly on the machine. With a constant
turning force applied, rotation of the planetary should be
consistent. If there is more drag at certain points, gears
are not rolling freely and the planetary should be ex-
amined for improper assembly or damaged compo-
nents.
