BRACKET 7W6903 - Caterpillar

Use a suitable driver to install cone (7) onto the pinion gear and install the pinion gear into the center housing. Install washer (5), sleeve (4) and washer (3) .Note: Always use a new sleeve (4) .
Use a suitable driver to install cone (1). Use an appropriate driver to install a new seal (12) .
If you are working on a pinion gear that is part of a front axle, install bracket (17). Secure the bracket with six bolts (16). Torque the bolts to a torque wrench setting of 85 N m (63 lb ft).
Install O-ring seal (10), yoke (15), washer (13) and a new nut (14). Tighten the nut until slight resistance is felt.Note: Nut (14) is a self-locking type. Always use a new nut.
Seat the bearings by striking both ends of the pinion gear with a soft mallet while tightening the nut until the rolling resistance begins to increase.

Checking the Rolling Resistance
Use tooling (A) to check the rolling resistance. Tighten nut (14) until the torque that is required to turn the assembly is between 4.9 N m (43 lb in) and 5.4 N m (48 lb in).Note: Seal (12) must be installed when you measure the rolling resistance.

Tooling (B) (18) 6HJ-2819 Bolt (19) 203-4348 Pinion depth gauge (20) 204-9319 Bar
Use tooling (B) to measure the depth of the pinion gear. Correct depth of the pinion gear is necessary in order to establish the correct tooth contact pattern.
Assemble tooling (B). One end of pinion depth gauge (19) is designed to fit over a left hand spiral. The opposite end will fit over a right hand spiral. The pinion gear that is used in the front axle has a left hand spiral. The pinion gear that is used in the rear axle has a right hand spiral. Spiral orientation is marked on the tool.

Tooling (C) (20) 204-9319 Bar (21) 6V-6106 Dial Indicator group (22) 3P-1565 Collet clamp (23) 5P-4156 Indicator base (24) 5P-4162 Indicator contact point (plunger) (25) Hole 98 mm (3.85 inch) (front axle) (26) Hole 20 mm (0.78 inch) (rear axle)
Assemble tooling (C) .
If you are setting the depth of the pinion gear for a front axle, install the contact point (plunger) on tool (C) into the 98 mm (3.86 inch) deep hole (25) in tool (A). Zero the dial indicator reading. If you are setting the depth of the pinion gear for a rear axle, install the contact point (plunger) on tool (C) into the 20 mm (0.78 inch) deep hole (26) in tool (A). Zero the dial indicator reading.Note: Check that the hole (25) or the hole (26) is clean. The dial indicator will not be set correctly if there is dirt in the hole. Use a micrometer to check the depth of hole (25) or hole (26) .
