4. Place pre tensioned probe (6) of gauge on measuring
arm of measuring device J–43038. The probe must
be set precisely between the notch marks, square to
the plane surface (7).

5. Determine the left and right stops by turning the
knurled bolt (2).
Set the dial of the gauge to zero.
Use the knurled bolt (2) to move the 2nd balancer
shaft (exhaust side) back and forth. Again —
simultaneously read off the tooth backlash from the
gauge.
The permissible tooth backlash is: 0.02 mm to
0.06 mm (0.0008 to 0.0024 in).
051RW007
6. The tooth backlash must be measured in 4 different
positions — turn the crankshaft further at the
fastening bolt of the timing belt drive gear by 45
°
in the
engine rotational direction until the measuring arm (2)
is at “6 o’clock”.
051RW008
7. Then loosen the knurled bolt (3) fix the measuring arm
at “9 o’clock” again and repeat the measurement.

8. If the value determined in one of the 4 measurements
lies outside the tolerance 0.02 mm to 0.06 mm
(0.0008 to 0.0024 in), the tooth backlash must be
adjusted.

9. Remove balance unit from cylinder block/crankshaft
bearing caps and remove with balancer piece. The
balancer piece has a number (code), for easy
assignment. The tooth backlash can be adjusted by
using a balancer piece with a different thickness.
Code
Thickness of balancer piece in mm
55
0.535 to 0.565
58
0.565 to 0.595
61
0.595 to 0.625
64
0.625 to 0.655
67
0.655 to 0.685
70
0.685 to 0.715
73
0.715 to 0.745
76
0.745 to 0.775
79
0.775 to 0.805
82
0.805 to 0.835
85
0.835 to 0.865
NOTE: The next larger or smaller balancer alters the
tooth backlash by 0.02 mm (0.0008 in).
Example of selection of balancer piece: The installed
balancer piece with the code “70” gave a tooth back-
lash of 0.08 mm (0.0031 in).
If a balancer piece with the code “67” is now
installed, the tooth backlash will be approx. 0.06 mm
(0.0024 in).
CAUTION: Only one balancer piece may be installed.
Reassembly
1. Turn crankshaft in engine rotational direction to
alignment mark (2) 1st cylinder “TDC”.
014RW066
2. Turn balancer shafts until the flattened sides (arrows)
of both balancer shafts face downward and are on a
horizontal line.
051RW010
3. Install selected balancer piece (2) with balancer shaft
unit to cylinder block/crankshaft bearing cap —
tighten all fixing bolts to the specified torque.
Torque: 20 N·m (15 lb ft)
4. After installing the balancer shaft unit, recheck the
tooth backlash and readjust if necessary.
NOTE: If the balancer shaft unit has to be replaced, use
the thickest balancer piece with the code “85” for the initial
assembly — this guarantees tooth backlash in all
conditions.
5. Install oil strainer to oil pump with new seal ring and
insert fixing bolts with locking agent to the specified
torque.
Torque: 8 N·m (6 lb ft)
