ASSEMBLY / ADJUSTMENTDrive AxleFinal Pinion Bearing Preload Test(cont'd)2. Measure Pinion Bearing Preload - Use aspring scale to test the assembly rollingtorque. To use the spring scale, wrap softwire around the bearing cage, attach thescale and pull. Preload is correct whentorque required to rotate the pinion bearingcage is from 15 to 35 LBS.-IN. (1.7-4.0 N.m).This specification is translated into springscale readings in the chart below.3. Adjust Pinion Bearing Preload - Ifnecessary, adjust pinion bearing preload.Disassemble the pinion bearing cage asrecommended in this manual and changethe pinion bearing spacer. A thicker spacerwill decrease preload. A thinner spacer willincrease preload.IMPORTANT: Use the correctly sizedspacer. Do not use shim stock or grindspacers. These practices can lead to loss ofbearing preload and gear or bearing failure.Install Pinion Oil Seal and Yoke1. With pinion bearing preload adjustmentcomplete, install oil seal. Use a press andproperly sized sleeve to prevent distortionor contact with seal lips during installation(see illustration).Section 32. Make sure yoke is clean and dry. Installyoke and nut (or nut and washer on somemodels). Tighten nut to correct torque (see .chart above~.NOTE: After tightening nut, recheck pinionbearing rolling torque, then proceed withpinion installation in carrier.Overhaul24
Drive AxleASSEMBLY / ADJUSTMENTInstall Drive Pinion1. Place shim pack on carrier.NOTE: If gear is to be reused, install samequantity and size of shims removed duringdisassembly. When installing a new gearset, use nominal shim pack (see chart).PINIONIN STALLAT IONAlign oilholes inshims \2. Install pinion assembly. Install bearingcage cap screws. Torque cap screws(see chart, back page).NOTE: After tightening pinion nut, recheckpinion bearing rolling torque.Install Differential andRing Gear AssemblyNOTE: Lubricate bearings during thefollowing assembly procedures.1. Place ring gear and differential assemblyin carrier. Insure that ring gear and drivepinion mesh properly.NOTE: During installation, tilt carrier toallow support case pilot to rest in carrierbore, then install bearing cup as shown inillustration. Also install bearing cup onopposite side of differential.CAUTION: When installing bearingcaps and adjusters, exercise care not tocross threads.2. Install bearing adjusters and caps.3. Install and tighten bearing cap screwsfinger-tight. If this is difficult, use handwrench.NOTE: The assembly is now ready foradjustment of differential bearing preload,ring gear backlash and gear tooth contact(see next page).Section 3Overhaul25
