Static balancing of front wheel/rear 
wheel

•

Install balancing shaft (1), BMW No. 36 3 606, 
with measuring bushing (2) and nut (3),
BMW No. 36 3 616, in front wheel bearings.

•

Lightly preload bearing with knurled nut (3).

•

At the rear wheel, bolt the mounting fixture (4),

•

Allow wheel to settle.

•

Clean points of adhesion for balance weights.

•

Attach adhesive weights (7) opposite the heavi-
est point on both sides of the wheel rim, with the 
total weight equally divided between the left and 
right sides.

e

 Caution:

Maximum balancing weight 60 g (2.12 oz).

•

Repeat the balancing procedure as a check.

Checking front/rear wheel rim for 
runout

•

Remove tyre.

•

Install the balancing shaft (1), 
BMW No. 36 3 606, with measuring bushing (2) 
and nut (3), BMW No. 36 3 616, in the front wheel 
bearings.

•

Lightly preload bearing with knurled nut (3).

•

Use pin (4) to lock the balancing shaft against the 
balancing stand to prevent the shaft from turn-
ing.

•

At the rear wheel, attach mounting fixture (5), 
BMW No. 36 3 613, on the centering collar side 
with the wheel studs, then install the balancing 
shaft.

•

Clamp locating discs (6), BMW No. 36 3 615, to 
the balancing shaft at left and right in such a way 
that the shaft cannot wander.

•

Align the balancing fixture, BMW No. 36 3 600, 
with the knurled screws/bubble gauge (7/8).

•

Check radial/axial runout.

e

 Caution:

Only apply dial gauge to machined inner face of 
wheel rim.

Max. vertical runout/horizontal runout

....................................................  1.3 mm (0.05 in)

Removing/installing spokes

e

 Caution:

It is not permitted to replace more than one spoke.

•

Unfasten grub screw (1).

•

Loosen the spoke nipple/remove the spoke.

•

Install new spoke.

•

Center the wheel rim.

Tightening torque:

Spoke nipple ................................................. 5 Nm

Centering the wheel rim

Max. permissible
lateral/vertical runout .................. 1.3 mm (0.05 in)
Max. horizontal runout which can
be eliminated by centering ......... 2.0 mm (0.08 in)

L

 Note:

Vertical runout cannot be compensated for by 
centering the rim.

Centering lateral runout

•

Determine maximum deviation (plus (+) and mi-
nus (-)).

•

To center the wheel, the spoke nipples must be 
tightened on the side directly opposite the larg-
est deviation.

•

Remove grub screw from relevant spoke nipple 
before tightening.

•

Working forwards and backwards from the max-
imum and minimum value points, take up slack at 
every third spoke nipple.

e

 Caution:

Never attempt to compensate for the entire horizon-
tal runout at only one or two spokes.

•

At the point where the maximum plus and minus 
values occur, take up slack at 2 spokes.

•

Four spokes are therefore tightened during each 
centering operation.

•

Check horizontal runout with a dial gauge.

•

After every correction of horizontal runout, check 
vertical runout again. 

•

If necessary, repeat the centering operation.

•

Lock tightened spokes into place with grub 
screws.
