Page 125 of 4770
(i) Check that the injectors rotate smoothly.
HINT: If injectors do not rotate smoothly, the probable
cause is incorrect installation of O±rings. Replace the
O±rings.

position on the cylinder head.
(h) Temporarily install the 2 bolts holding the delivery
pipe to the cylinder head.

2. CHECK THRUST CLEARANCES OF NO.1 AND NO.2
BALANCE SHAFT OF ENGINE BALANCER
Using a dial indicator, measure the thrust clearance
while moving the balance shaft back and forth.
Standard thrust clearance:
0.065 ± 0.110 mm (0.0026 ± 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.
3. CHECK BACKLASH OF CRANKSHAFT GEAR AND
NO.1 BALANCE SHAFT GEAR
NOTICE:
wBacklash 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.
wAccordingly, it is necessary to measure the backlash
at the 4 points shown in the illustration on the left.
When this inspection is performed on±vehicle, the
specifications are increased by approx. 0.025 mm
(See specifications below)
CYLINDER BLOCK DISASSEMBLY
(See Components for Cylinder Block Disassembly
and Assembly)
1. REMOVE REAR OIL SEAL RETAINER
Remove the 6 bolts, retainer and gasket.
(a) Rotate the crankshaft 2 or 3 times to settle the crank±
shaft gear and No.1 balance shaft gear.
(b) When 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.

Page 145 of 4770

(f) Lightly turn the No. 1 balance shaft by hand and meas±
ure the backlash.
HINT:
wTurn the No.1 balance shaft 4 or 5 times to
provide a steady backlash reading.
wTo prevent excessive backlash due to thrust cle±
arance, measure the backlash while pressing on
the rear of the No.1 balance shaft.
Standard backlash:
Off±vehicle
0±0.06 mm (0±0.0024 In.)
On±vehicle
0.025 ± 0.080 mm (0.0010 ± 0.0035 in.)
NOTICE: Do not turn the No.1 balance shaft strongly.
(g) Remove the dial gauge and the SST. (e) Set the SST and the dial indicator as shown in the
illustration.
SST 09224± 74010
HINT: Make sure that the±needle of the dial indicator is
perpendicular to the SST and that it is placed in the
middle of the third indention.(d) 1 st turn the crankshaft clockwise, and align the
groove of the No.2 balance shaft housing with the
punch mark A of the No. 1 balance shaft. (c) Check that the punch marks A and B are at the
positions on the No.1 balance shaft indicated in the
illustration.

5. CHECK CONNECTING ROD THRUST CLEARANCE
Using a dial indicator, measure the thrust clearance
while moving the connecting rod back and forth.
Standard thrust clearance:
0.160 ± 0.312 mm (0.0063 ± 0.0123 in.)
Maximum thrust clearance:
0.36 mm (0.0138 in.)
If the thrust clearance is greater than maximum, re±
place the connecting rod assembly. If necessary, re±
place the crankshaft.
6. REMOVE CONNECTING ROD CAPS AND CHECK
OIL CLEARANCE
