1. Grip the spiral bevel pinion nut with a torque wrench and measure the turning torque. 2. If the turning torque is not within the factory specifications, check the differential gear turning force, backlash and tooth contact again.
1. Measure free length of spring with vernier caliper. 2. If the free length is less than the allowable limit, replace.
1. Place for in the groove to check clearance with feeler gauge. 2. If the clearance exceeds allowable limit, replace.
1. Secure the gear with a vise. 2. Set a dial indicator (lever type) with its finger on the spline. 3. Move the shaft to measure the clearance. 4. If the clearance exceeds the allowable limit, replace them.
1. Set a dial indicator (lever type) on one of the tooth faces. 2. Clamp the mating gear. 3. Measure backlash by turning the gear to be measured. 4. If the reading exceeds the allowable limit, replace the gear.
1. Hold the inner race, and push and pull the outer race in all directions to check for wear and roughness. 2. Apply transmission fluid to the bearing, and hold the inner race. Then turn the outer race to check rotation. 3. If there is any defect, replace it.
1. Check the spring (3) and the poppet (4) for scratches, damage and breakage. 2. If anything is unusual, replace it.
1. Check the plug (1), O-ring (4), the spring (2) and the valve poppet (3) for scratches, damage and breakage. 2. If anything is unusual, replace it.
1. Check the spring (2) and check and high pressure relief valve (3) for scratches and damage. 2. Check the valve seal in the port block cover for damage. 3. If anything is unusual, replace the check and high pressure relief valve as an assembly.
1. Check the piston contact face of the thrust plate (1), and the thrust plate contact face of the swashplate (2) for scratches and excessive wear. 2. If the thrust plate (1) and the swashplate (2) are worn and scored, replace them.
