Instructions for changing and installing wheels: Notes

The following instructions must be performed on the removal of wheel (rim).

• Check whether the rim contact surfaces on the brake disc/ wheel (rim) as well as brake disc/wheel hub are free of corrosion and dirt. Remove oil, grease, and corrosion as necessary
• Check that the centering holes of the wheel (rim) and the centering flange of the hub are free of corrosion and dirt. If necessary, remove any oil, grease and corrosion and apply Wax Spray D 322 000 A2 to ensure that the parts are protected against corrosion.
  NOTE: The wax spray must not come into contact with brake system components.
• If rust drops between the brake disc and the wheel hub during disassembly, remove it by blowing out with compressed air.
  WARNING: Always wear protective glasses.
• Check wheel bolts and wheel hub threads for cleanliness. The wheel bolts must be able to be screwed in the entire thread length when installing the wheel.
• Use a wire brush to clean dirty wheel bolts. Heavily corroded and/or damaged wheel bolts must be replaced.
• Lightly corroded wheel bolts are re-used, the bolts must be cleaned in the area of the contact surface and on the threads while on the sliding surfaces Optimol TA paste, Part No. G 052 109 A2 must be applied as follows:
  1. • Threaded portion -1- and contact surface -2- to be greased lightly
  2. • Grease lightly at threaded portion -4- as well as between bolt head contact surface -3- and ring.
     • The contact surface -5- toward the wheel rim must not be greased

  NOTE: Use Optimol TA paste, Part-No. G 052 109 A2. The paste must not make contact with brake system components.
• Make sure that the bore of the brake disc aligns with the thread of the hub. The thread of the lug bolts must not contact the brake disc hole.
