BORING OF CYLINDERS
NOTE; .-
l Bore all six cylinders for the oversized piston. outside
diameter.
l Replace the piston rings with ones to match, the over-
sized pistons.

3. SELECT OVERSIZED PISTON
Oversized piston diameter:
O/S, 0.50 7M-GE 83.40 - 83.45 mm
(3.2835 - 3.2854 in.)
7M-GTE 8341.. - 83.46.mm
(3.2839 - 3.2858 in.)
CALCULATE AMOUNT TO BORE CYLINDER
(a) Using a micrometer, measure the piston diameter at a
right angle to the piston pin hole center line, 22 mm
(0.87 in.) from the piston head.
(b) Calculate the amount each cylinder is to be rebored
as follows:
Size to be rebored = P + C - H
P = Piston diameter
C = Piston clearance
7M-GE 0.08 - 0.10 mm
(0.0020 - 0.0028 in.1
7M-GTE 0.07 - 0.09 mm
(0.0028 - 0.0035 in.)
H = Allowance for honing
0.02 mm (0.0008 in.) or less
BORE AND HONE CYLINDERS TO CALCULATED
DIMENSIONS
Maximum honing: 0.02 mm (0.0008 in.)
CAUTION: Excess honing will destroy the finished
roundness.

INSPECTIC)N OF CRANKSHAFT
1. INSPECT CRANKSHAFT FOR RUNOUT
(a) Place the crankshaft on V-blocks.
(b) Using a dial indicator, measure the circle runout at
the center journal.
Maximum circle runout: 0.08 mm (0.0024 in.)
If the circle runout is greater than maximum, replace the ’
crankshaft.
NOTE: Use a long spindle on the,,dial gauge.
2. INSPECT MAIN JOURNALS AND CRANK PINS
(a) Using a micrometer, measure the diameter of each
main journal and crank pin.
Journal diameter:
STD size’ 59.994 - 60.012 mm
(2.3620 - 2.3627 in.1
U/S 0.25 59.730 - 59.740 mm
(2.3516 - 2.3520,in.I
Crank pin diameter:
STD size 51.976 - 52.000 mm
(2.0463 - 2.0472 in.)
U/S 0.25 51.725 - 51.735 mm
(2.0364 - 2.0368 in.)
If the diameter is not within specification, check the oil
clearance. If necessary, grind or replace the crankshaft.
(b) Check each main journal and crank pin for taper and
out-of-round as shown.
Maximum taper and out-of-round: 0.02 mm
(0.0008 in.1
If taper or out-of-round is greater than maximum, replace
the crankshaft.
3. IF NECESSARY, GRIND AND HONE MAIN JOURNALS
AND/OR CRANK PINS
Grind and hone the main journals and/or crank pins to the
finished undersized diameter (See procedure step 2).
Install new main journal and/or crank pin undersized bear-
ings.

(1.2976 - 1.2982 in.)
(b) Using a cylinder gauge, measure the inside dia,meter
of the pump drive shaft bearing.
Bearing inside diameter:
Front 41 .OOO - 41.025 mm
il.6142 - 1.6152 in.)

(c) Subtract the journal diameter measurement from the
bearing inside diameter measurement.
Standard oil clearance: 0.025 - 0.066 mm
(0.0010 - 0.0026 in.)
Maximum oil clearance: 0.08 mm (0.0031 in.)
If the clearance is greater than maximum, replace the
bearing. If necessary, replace the drive shaft.
IF NECESSARY, REPLACE OIL PUMP DRIVE SHAFT
BEARING
(a) Using SST, replace the No. 1 bearing by using No. 2
bearing as a guide.

09215-00140, 09215-00160,09215-00210,
09215-00220)
(b) Using SST, replace the No. 2 bearing by using the No.
1 bearing as a guide.

Using a thickness gauge, measure the drive shaft thrust
clearance’between the thrust plate and collar.
Standard thrust clearance: 0.06 - 0.13 mm
(0.0024 - 0.0051 in.)
Maximum thrust clearance: 0.30 mm (0.0118 in.)
If clearance is greater than maximum, replace the thrust
plate and/or collar.
