Wheels, Instructions For Changing/Installing

Wheels, instructions for changing/installing

CAUTION! Perform the checks and follow the instructions listed below. This is important to ensure that the wheel bolts and the wheels are properly secured.

Perform the following steps with the wheel rim removed.
- Check that the convex seats for the wheel bolts in the rim and the contact surfaces (rim/brake disc and brake disc/wheel hub) are free of corrosion and dirt. Remove any oil, grease and corrosion.
- Check that the centering hole in the wheel rim and the centering flange on the wheel hub are free from corrosion and dirt. Remove any oil, grease and corrosion and apply Wax Spray D 322 000 A2 to ensure corrosion protection.
- Check that the wheel bolts and the threads in the wheel hubs are clean. When installing the wheel, the wheel bolts should screw in easily over the full thread length of the threads.
- Use a wire brush or similar to clean dirty wheel bolts. Damaged or badly corroded wheel bolts must be replaced.





- If slightly corroded wheel bolts are re-used on the vehicle, clean the threads and the convex shoulders on the bolt heads and grease the surfaces in sliding contact using Optimol TA paste, Part No. G052109A2 as follows:
A - One-piece wheel bolt
^ Lightly grease thread - 1 - and convex shoulder - 2 -.
B - Two-piece wheel bolt
^ Lightly grease thread - 4 -, and the area between the bolt head contact surface - 3 - and the back of the convex washer - 6 -.
^ Do not apply grease to the convex surface - 5 - that bears against the wheel rim.

Note: Use only Optimol TA paste, Part No. G052109A2. The paste must not come into contact with parts of the brake system.

- Make sure that the hole in the brake disc lines up with the thread in the hub. The thread of the wheel bolts must not contact the hole in the brake disc.

Installing wheels
- Secure all wheels as follows:
- Thread in wheel bolts uniformly by hand.
- While vehicle is still raised, tighten wheel bolts in diagonal sequence.
^ Tightening torque: 50 Nm
- Lower vehicle onto the ground and tighten wheel bolts in diagonal sequence to final torque.
^ Tightening torque: 120 Nm
