Notes for repairing aluminum rims

In general, the economic viability must be checked prior to the repair.

It is possible to repair the following damage (applies to cast aluminum rims labelled as AlSi7 AlSi11, AlSi12):

  • Depth of the damage in the aluminum at maximum 1 mm
  • Distance of the damage from the outer rim edge at maximum 50 mm
  • Paintwork damage on the remaining wheel rim

It is not possible to repair the following damage:

  • Deformation and cracks
  • Polished, forged aluminum wheel rims are unsuitable for repair.

NOTES ON EXCHANGING TIRES DURING REPAIR

General:

  • The tire size, manufacturer and tire tread must be the same on one axle
  • To meet the BMW standards, the vehicle should be equipped with tires from the same manufacturer and with the same tire tread (tires approved by BMW) on all 4 wheels
  • The difference in tire tread depth on one axle must not exceed 2 mm (control quality of suspension control systems and wheel alignment requirement)
  • The tires with the higher tread depths must be mounted on the rear axle
  • The DOT age difference must not exceed 4 years
  • On exchanging the tires, the tire pressure must be adjusted

Additionally for all-wheel drive vehicles:

  • The tire size, manufacturer and tire tread must be identical on all wheels; if mixed tires are fitted, different dimensions are permissible.
  • The difference in tire tread depth on all wheels must not exceed 2 mm (control quality of suspension control systems and wheel alignment requirement)

Remove or install front or rear wheel

Special tools required:

  • 36 1 300
  • 81 25 2 344 011
  • 36 1 335
  • 36 1 010

IMPORTANT: Wheel was balanced electronically.

Observe safety information on raising the vehicle.

Adhere to the instructions on initializing the Run Flat Indicator (RPA).

During the installation of all four wheels (e.g. when changing from summer to winter wheels), the tire pressure must be checked! Observe the notes on tolerance compensation for the tire pressure control!

Observe the following procedure to prevent clamping errors and imbalance:

  • Loosen wheel studs.
  • Wheel positioned with valve facing down.
  • If several wheels are simultaneously removed, mark installation position of wheels on tires (e.g. with a piece of chalk).
  • Mark out wheel to wheel hub.
  • Mark out lockable wheel stud in relation to wheel.
  • Unscrew wheel studs. Remove wheel.
Suspension

IMPORTANT: Some of the rim styling must be positioned in a certain direction! Observe direction-of-rotation arrow on the wheel rim.

Suspension

IMPORTANT: Contact surfaces between:

  • brake disc and wheel rim,
  • brake disc and wheel hub,

must be clean and free from grease.

Remove dirt, grease residues and corrosion from contact surface with a drill and special tool 81 25 2 344 011.

IMPORTANT: Do not operate special tool 81 25 2 344 011 with an impact screwdriver!

NOTE: Degrease contact surface with universal cleaner.

Suspension

NOTE: If there are grease residues in the area of the wheel stud hole, the brake disc must be removed and cleaned.

Remove dirt, grease residues and corrosion from contact surface with a drill and special tool 81 25 2 344 011.

IMPORTANT: Do not operate special tool 81 25 2 344 011 with an impact screwdriver!

NOTE: Degrease contact surface with universal cleaner.

Suspension

Check brake disc retaining bolt (1) for tight fit.

IMPORTANT: Mounting bolt (1) must not under any circumstances protrude over contact surface (2) between brake disc and wheel rim.

Tightening torque brake disc retaining bolt:

  • Front axle 34 11 1AZ
  • Rear axle 34 21 1AZ
Suspension

Apply a thin coat of grease to wheel centering (1) in wheel rim.

Suspension

NOTE: To release and tighten lockable wheel bolts, use a matching adapter from special tool 36 1 300, 36 1 335 or 36 1 010.

Suspension

Clean wheel studs and check threads for damage, replace, if necessary.

Replace rusty wheel studs.

IMPORTANT: Do not apply oil to wheel studs.

IMPORTANT: Under no circumstances use pneumatic or electric screwdrivers to install and tighten the wheel studs.

IMPORTANT: Wheel rim must rest uniformly against the brake disc.

In the case of non-original BMW wheel studs/rims it may be necessary to retighten the wheel studs on account of setting properties (refer to manufacturer's documents).

Suspension

Tightening specifications:

1. Screw in wheel bolts and evenly tighten crosswise by hand in order to center the wheel rim.

2. Tighten down wheel studs in crosswise sequence with a calibrated torque wrench to prescribed tightening torque 36 10 1AZ .

3. Check all the wheel bolts in the same order or retighten to the prescribed tightening torque again.

Stationary wheel balancing

Special tools required:

  • 36 1 010
  • 36 1 020

Necessary preliminary tasks:

  • Remove WHEEL.

IMPORTANT: Use only BMW-approved balance weights.

Remove any fitted balancing weights, stones in tread pattern and larger dirt contaminations.

Check tire pressure and tire for condition, damage, flat spots (irregularities caused by e.g. parking of vehicle with tires which have run hot). If necessary, check WHEEL AND TIRE for radial and lateral runout.

Suspension

Use BMW-approved wheel centering elements of relevant balancing machine manufacturers.

  1. Basic flange
  2. Wheel centering element
  3. Type flange
  4. Clamping nut
    Suspension

IMPORTANT: To avoid clamping errors, it will be necessary to fit the wheel on the balancing machine in the same way (e.g. valve facing down) as it is then fitted on the vehicle.

Balance wheel in accordance with operating instructions of relevant balancing machine.

On light-alloy rims with distinctive J-shape rim flange, proceed as follows:

  1. Gently force off tire sidewall with special tool 36 1 020 at appropriate point from rim flange.
  2. Install retaining clip (1).
  3. Remove special tool 36 1 020 .
    Suspension

Raise retaining clip with special tool 36 1 010. Slide balance weight underneath and allow it to snap into place.

Suspension

Arrangement of balance weights for light-alloy rims with distinctive J-shape rim flanges.

  1. Retaining spring
  2. Balance weight

Adhesive weights must be used on all other light-alloy rims.

Max. imbalance.

Suspension

NOTE: When using adhesive weights, proceed as follows:

  1. Carefully remove any adhesive weights. Do not damage wheel rim when doing so.
  2. Select suitable location for fitting.
  3. Clean adhesive area thoroughly.
