|
| 19. |
At toothed belt drive gear fastening bolt, turn crankshaft in
direction of engine rotation to "Cylinder no.1 TDC " (mark 2).
|
| 20. |
In this crankshaft position, the flattened sides (arrows) of
both balancer shafts must point down and form a horizontal
line.
|
|
|
Install
| 21. |
Screw measuring device KM-949 (3)
into 1st balancer shaft (intake side) using long knurled bolt (1)
and hand-tighten
Note: Measuring arm (5)
must point in "9 o'clock" direction
|
| 22. |
Screw short knurled bolt (2) into 2nd balancer shaft (exhaust
side) and also hand-tighten
|
| 23. |
Fit dial gauge bracket with dial gauge KM-798 (4) to cylinder block and place dial gauge
plunger (6) against measuring arm of measuring device KM-949 under pre-tension
Note: The plunger must
be placed exactly between the notch marks, vertically to the flat
plane (7)
|
| 24. |
Determine left and right stop positions by turning knurled bolt
(2) backwards and forwards. Set dial of dial gauge to zero.
|
|
|
| 25. |
Move 2nd balancer shaft (exhaust side) forwards and backwards
again at knurled bolt (1) - read off tooth backlash from dial gauge
at same time.
|
| 26. |
Permissible backlash is: 0.02 mm to 0.06 mm.
|
| 27. |
The tooth backlash must be measured in 4 different positions -
to do this, continue rotating crankshaft at toothed belt drive gear
fastening bolt in steps of 90° in direction of engine rotation
until measuring arm (2) is in the "6 o'clock" position.
|
| 28. |
Then loosen the knurled bolt (3), move measuring arm to "9
o'clock" again and repeat measurement.
|
| 29. |
If any of the 4 measurements is out of tolerance (0.02 mm to
0.06 mm) the tooth backlash must be adjusted.
