Note. The following special tools are required for the work described below: sensitive torque wrench (for measuring the initial turning moment of the pendulum arm); special steering arm puller (to remove the pendulum arm).
Removing
1. Jack up the front of the car and place it on jack stands.
2. Remove cotter pins, then give castellated nuts of fastening to assemblage of the pendulum lever of longitudinal and cross steering draughts.
3. If a puller is not available, release the ball studs of the pendulum arm assembly using an alternative method using two hammers.
4. Give bolts of fastening of assemblage of the pendulum lever of cross steering draft to the chassis and remove assembly from the car.
Installation
Installation is in the reverse order.
1. Tighten the assembly mounting bolts with a force of 45÷55 Nm.
2. The nominal tightening torque of castle nuts is 88÷113 Nm.
3. Cotter pins must be replaced without fail.
4. Finally, use a grease gun to lubricate the swingarm assembly with the correct grade of grease.
Disassembly
1. Remove the tie rod swing arm assembly from the vehicle.
2. Clamp the assembly firmly in a vise with soft jaws. Remove the cotter pin and give the fixing nut (assembly components are shown in the accompanying illustration). Using a steering arm puller, remove the swing arm from its axle.
1 - cotter pin; 2 - nut; 3 - pendulum lever; 4 - stuffing box; 5 - casing; 6 - bushings; 7 - axis; 8 - spring; 9 - spring plate; 10 - gasket; 11 - cover; 12 - bolts
3. Give bolts of fastening of a cover of the pendulum lever to a casing.
4. Remove the spring with its plate, discard the gasket.
5. Take an axis from a casing and remove the top plug.
6. Using a suitable drift and hammer, carefully knock the oil seal out of the lower end of the casing, then remove the lower bushing.
Cleaning and checking the condition of components
1. Wash all assembly components in a suitable solvent, then dry thoroughly.
2. Inspect the assembly cover for cracks or other damage.
3. Check up a condition of an axis, a casing and plugs. Replace defective components if signs of wear or damage are found.
4. Check the condition (degree of wear and weakening of the compression force) springs.
5. Inspect the lever for cracks or other damage.
Assembly
Assembly is carried out in the reverse order of dismantling.
1. Install the bushings in the swingarm housing.
2. Lubricate the outside of the new oil seal with a suitable sealant, then seat it with a mandrel from below into the casing. Lubricate the seal lips with multipurpose grease.
3. Lubricate the contact surfaces of the bushings of the casing and the axle with multipurpose grease, then insert the axle into the casing
4. Install the plate and spring. Make sure that the tongues of the spring plate are correctly located in the casing.
5. Install the swingarm housing cover with a new gasket, securely tighten the mounting bolts.
6. Put the lever on the axle, firmly tighten the fixing nut and fix it with a cotter pin.
7. Measure the starting torque of the pendulum arm:
- Grab the lever and move it back and forth about 90°to spread the lubricant.
- Put a replaceable end head on the lever axle nut.
- Connect a sensitive torque wrench to the head and, applying force to the wrench collar, read the amount of torque at the moment the lever is pulled away. The nominal value is 4.9 Nm.
- If the measurement result does not correspond to the required value, the lever must be disassembled and the cause of the bite removed.
