FRONT FINAL DRIVE ASSEMBLY FFD-27 C E F G H I J K L M A B FFD 9. If the turning torque is outside the specification, use a thicker/ 10. Record the total amount of shim thickness required for the cor- rect carrier side bearing preload. Pinion Gear Height If the hypoid gear set has been replaced, select the pinion height adjusting washer. 1. Use the formula below to calculate pinion height adjusting 2. Select the proper pinion height adjusting washer. Refer to FFD-36, "Pinion Height Adjusting Washer" If impossible find the desired thickness of washer, use washer with thickness closest to the calculated Pinion Bearing Preload ● Assemble the drive pinion parts if they are disassembled. Refer to FFD-28, "Drive Pinion Assembly" 1. Make sure all parts are clean. Also, make sure the bearings are well lubricated with gear oil. 2. Install companion flange (1). NOTE: If the turning torque is less than the specified range: Decrease the side bearing adjusting shim thickness. If the turning torque is greater than the specification: Increase the side bearing adjusting shim thickness. SPD772 Washer selection equation: T = T 0 + (t 1 - t 2 ) T: Correct washer thickness T 0 : Removed washer thickness t 1 : Old drive pinion head letter “H × 0.01” (“H”: machined tolerance 1/100 mm × 100) t 2 : New drive pinion head letter “H × 0.01” (“H”: machined tolerance 1/100 mm × 100) Example: T = 3.21 + [(2 × 0.01) - (-1 × 0.01)] = 3.24 T 0
: 3.21 t 1
