ENGINE MECHANICAL (Y22SE 2.2L)

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 (1) 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

0.535 to 0.565

58

0.565 to 0.595

61

0.595 to 0.625

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 for selection of balancer piece: The
installed balancer piece with the code “70” gave a
tooth backlash 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 align

the alignment mark (2) at 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: 30 N·m (22 lb ft)

CAUTION: Take great care not to chip or dent teeth
when meshing gear sets on assembly.

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 (69 lb in)

6. Install oil pan support.

Torque: 20 N·m (14 lb ft)

D

Adjust surfaces of the cylinder block and the oil pan
support.

7. Install oil pan.

Torque: 8 N·m (69 lb in)
