27 REAR AXLE Place the proper thickness depth shim on pinion gear and install the rear pinion bearing cone; using Installer, rear pinion bearing cone Pt. no. 2698 5890 3519 Fig. 45 Assemble bearing cone, slinger and new pinion seal into housing. Use Installer, pinion oil seal Pt. no. 2698 5890 3513 and handle universal Pt. no. 2698 5390 3506. Fig. 46 Apply a light coat of oil to the lip of oil seal. Install new collapsible spacer onto pinion stem and assemble into housing. Using Holder, yoke Pt. no. 2698 5890 3505 and Installer, yoke Pt. no. 2698 5890 3518. assemble end yoke, washer and new pinion nut. Using holder, yoke Pt. no. 2698 5890 3505 and torque wrench. Tighten to the specified torque or until all end play is removed. Continue to tighten in small increments until the rotating torque is achieved. Note: Exercise care during the bearing preload torque adjustment. DO NOT over tighten loosen and then retighten the nut. DO NOT exceed the bearing preload torque. If preload torque is exceeded, a new collapsible spacer must be installed and the torque sequence repeated. Check for the rotating torque of pinion. It should read between the 2.26 – 4.52 Nm with new bearings. Note: If only oil seal is changed use new collapsible spacer and keep same rotational torque of pinion as before changing oil seal.
