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
58
61
64
67
70
73
76
79
82
85
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.

2. Turn balancer shafts until the flattened sides (arrows)
of both balancer shafts face downward and are on a
horizontal line.
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)
