Assembling the Steering Gear Box
Sand Pro ® 3040 and 5040
20251SL Rev A
1. If removed, install the bushings into the gear box cover and the gear box
plate. Make sure that the bushing flange is fully seated.
2. Apply Molilgrease XHP high temperature grease (or equivalent) to the
bearing surfaces of the flange bushings.
3. If the bearings were removed from the pinion gear shaft:
A. Press the first bearing onto the shaft by applying pressure to the inner
bearing race.
B. Slide the spacer tube onto the pinion shaft and then press second bearing
onto shaft by applying pressure to the inner bearing race.
C. Install the retaining ring to secure the bearings to the pinion gear shaft.
4. Slide the pinion gear assembly into the steering cover and secure the
assembly with the retaining ring.
5. Apply Molilgrease XHP high temperature grease (or equivalent) to the pinion
gear and sector gear teeth, and to the sector gear bearing surfaces.
6. Install the sector gear into the gear box cover making sure to align the sector
gear and pinion gear teeth.
7. Fill the gear box cover with Molilgrease XHP high temperature grease (or
equivalent).
8. Install the shim(s), gasket, and the gear box plate to the gear box cover.
9. Secure the gear box plate to the cover with the previously removed fasteners.
Tighten the fasteners in a crossing pattern from 20 to 25 N·m (175 to 225
in-lb).
10. After assembling the gear box, make sure that sector gear has minimal end
play in the cover and plate assembly. Check that the pinion shaft rotates
freely. The maximum input torque to rotate the pinion shaft must be less
than 0.56 N·m (5 in-lb). If necessary, add or remove shims to adjust the
end play and input torque.
