PULLEY 4P3714 - Caterpillar

Illustration 28 g01006255
Use Tooling (P) in order to measure the thickness of thrust washer (9) , 6 plates (11) , and 5 discs (12) as they are assembled in brake housing. Subtract the thickness of the bar stock. Record this dimension as Dimension (Y) .
Determine the piston stroke by subtracting Dimension (Y) from Dimension (X) .Note: The piston stroke must be 2.6 0.2 mm (0.10 0.01 inch).Note: Plates are available in various thicknesses. Use various thicknesses of plates as needed to achieve proper piston stroke.Note: Install the thinner plates to the outside of the pack.

Push in on sun gear (6A) . Use Tooling (L) to measure the distance from the end of the sun gear to the mating surface on the hub, as shown. Subtract the thickness of the bar stock. Record this dimension as Dimension (J) .
Subtract Dimension (J) from Dimension (H) . Record this dimension as Dimension (K) . Subtract the desired end play of 0.50 0.10 mm (0.020 0.004 inch) from dimension (K) in order to determine the correct thickness of thrust washer (4A) .

Note: Engaging the planetary gears in carrier housing (2) with the ring gear may be difficult during the installation of the planetary carrier.
Fasten a suitable lifting device to the lifting sling. Place the planetary carrier in the planetary carrier's original location on the wheel studs in the hub. Temporarily install four lug nuts. Install the lug nuts in 90 degree intervals. The planetary gears in the planetary carrier will not be engaged with ring gear (15) at this time. Slowly rotate the hub on the opposite side of the axle. Tighten each lug nut slightly. Continue to tighten each lug nut slightly. The force of the lug nuts against the planetary carrier and the slow rotation of the hub will cause the planetary gears in the planetary carrier to engage with the ring gear. After the planetary
