Wheels, Changing and Mounting Notes
Note: The wrench size of the included wheel bolt adapter can vary from the wrench size of the respective master set.
Special tools, testers and auxiliary items required
^ Torque wrench V.A.G 1332
^ Master Wheel Bolt Key Set T10101
^ Master Wheel Bolt Key Set T40004
^ Master Wheel Bolt Key Set T40073
^ Wax Spray D 322 000 A2
^ Optimol TA Paste G 052 109 A2
Changing Wheels
CAUTION! If brake pads are ceramics, wheel must not fall on brake disc, otherwise it will be irreparably damaged. To remove/install wheel, install long assembly pin instead of wheel bolts in top position (12:00 position) and short assembly pin in wheel bolt mounts for support. In this way, the wheel can glide on the assembly aids when removing/installing.
Note:
^ Only raise vehicle at designated mounting points.
^ On vehicles with alloy wheels, do not pry out cover caps with a screwdriver but rather use only the special tool designed for this (puller hook in vehicle tool kit).
^ To loosen wheel bolts, use sockets in the correct size. Sockets that did not fit must not be used any more.
^ Do not use an impact wrench to loosen anti-theft wheel bolts (lockable wheel bolts).
^ Do not make wheel bolts dirty.
CAUTION! The secure seating of the wheel bolts and the wheels is only ensured if the instruction and checks below are followed.
The following checks and instructions must be performed with wheel (rim) unmounted!
- Check if contact surfaces between the brake disc/wheel hub brake disc/brake drum and wheel (rim) are free of corrosion and dirt.
- If necessary, remove oil, grease, grease and corrosion.
- Ensure that the centering hole of the wheel (rim) and the center of the wheel hub are free of corrosion and dirt.
- If necessary, remove oil, dirt and corrosion and reapply corrosion protection in centering seat area with Wax Spray D 322 000 A2.
Note:
^ The wax spray must not get onto brake system parts.
^ If rust or dirt falls between brake disc and wheel hub during removal, remove it by blowing out with compressed air.
CAUTION! Wear protective eye wear when working with compressed air.
The wheel (rim) spherical caps and wheel bolts must be free of dirt and corrosion.
- Dirty wheel (rim) spherical caps should be cleaned with a lint-free cloth.
- Check wheel bolts and wheel hub threads for cleanliness.
- Clean dirty wheel bolts in spherical cap area and threads, e.g. with a brass brush.
Note: Heavily corroded or damaged wheel bolts must be replaced.
If lightly corroded wheel bolts are reused, they must be cleaned in area of spherical cap and threads and Optimol AT G 052 109 A2 paste must be applied to slide surfaces as follows (all vehicles except RS 2 and RS 4, type 8D):
A - One-part wheel bolt. Lightly lubricate threaded area - 2 - and spherical cap - 1 -.
B - Two-part wheel bolt. Lightly lubricate threaded area - 3 - as well as between bolt head contact surface - 6 - and spherical cap ring - 5 -. The spherical cap to wheel (rim) contact surface - 4 - must not be lubricated.
Note: Only use Optimol TA G 052 109 A2 paste. The paste must not get on brake system parts.
Changing Wheels
Only for RS 2 and RS 4 type 8D:
^ Lightly corroded wheel bolts must not be cleaned and lubricated. These wheel bolts should be replaced.
^ Install wheel bolts dry.
Continued for all vehicles:
- Check whether the wheel bolts can be easily installed by hand without tools. It must be easy to install the wheel bolts the entire length of the threads when installing the wheel.
- Ensure threads align with the hub. The threads of the wheel bolts must not touch the holes in the brake disc.
- If the thread of the wheel bolt touches the hole, turn the brake disc relative to the wheel accordingly.
Wheel mounting:
- Place wheel on wheel hub and secure it by hand with two wheel bolts on opposite sides.
- Install remaining wheel bolts by hand, they must be easy to install. Ensure they are centered exactly.
- Take load off wheel if necessary by raising slightly and lightly tighten two wheel bolts by hand.
- When mounting a wheel, tighten all wheel bolts uniformly by hand.
- Tighten the wheel bolts diagonally using, for example, a four-way lug wrench, to about 50 Nm.
- Lower the vehicle to the floor and tighten diagonally all wheel bolts to the specification.
Note: Never use an impact wrench to mount wheels!
- Lower vehicle onto its wheels.
