11. CHECK THRUST CLEARANCES OF NO.1 AND NO.2
BALANCE SHAFTS OF ENGINE BALANCER
Using a dial indicator, measure the thrust clearance while mov-
ing the balance shaft back and forth.
Standard thrust clearance:
0.060 ± 0.110 mm (0.0024 ± 0.0043 in.)
Maximum clearance: 0.11 mm (0.0043 in.)
If the clearance is greater than maximum, replace the balance
shaft housings and bearings. If necessary, replace the balance
shafts.
12. CHECK AND ADJUST BACKLASH OF CRANKSHAFT
GEAR AND NO.1 BALANCE SHAFT GEAR
NOTICE:
Backlash between the crankshaft gear and No.1 balance
shaft gear varies with the rotation of the balance shaft and
the deviation of the crankshaft gear. Accordingly, it is nec-
essary to measure the backlash at the 4 points shown in
the illustration on the left.
(a) Turn the crankshaft 2 or 3 times to settle the crankshaft
gear and No.1 balance shaft gear.
(b) When the No.1 piston is at TDC, check that the punch
marks shown in the illustration of the balance shafts are
aligned with the grooves of the No.2 housing.
(c) Check that punch marks A and B are at the positions on
the No.1 balance shaft indicated in the illustration.

If the oil clearance is greater than maximum, replace the bear-
ings. If necessary, grind or replace the crankshaft.
HINT:
If using a standard bearing, replace it with one having the same
number marked on the connecting rod cap. There are 3 sizes
of standard bearings, marked º1º, º2º and º3º accordingly.
Reference
