4. Install the 1P5512 Contact Point on dial indica-
tor (6). Put the dial indicator in the 1P2402
Gauge Body. To adjust the dial indicator to zero,
put dial indicator and gauge body on the 1P5507
Gauge. Move the dial indicator until the hand
moves 1/4 turn. Tighten bolt on body to hold the
dial indicator in this position. Turn the dial face
until the zero is in alignment with the hand.
5. Measure the cylinder liner projection as close as
possible to the four corners of the adapter plate
on the liner. The liner projection must be 0.033
to 0.175 mm (.0012 to .0069 in.). The difference
between the four measurements must not be
more than 0.05 mm (.002 in.). The difference in
the average cylinder liner projection of liners
next to each other must not be mom than 0.05
mm (.002 in.). The maximum difference in the
average projection for all cyliner liners must not
be more than 0.08 mm (.003 in.).
MEASURING CYLINDER LINER PROJECTION
1. S1589 Bolt with two 1S379 Washere. 2. Crossbar. 3.
1D4595 Bolt, 4. Spacer plata. 5. 3H4S5 Plataa. 6. 1P2403
Dial Indicator. 7. 1P23S4 Adaptar Plata.
NOTE: If the liner projection changes from point to
point around the liner, turn the liner to a new position
in the bore. If the liner projection is still not to
specifications, move the liner to a different bore.
6. When the cylinder liner projection is correct, put
a temporary mark on the liner and the spacer
plate so at final installation the liner can be
installed in the correct position.
Cylinder liner projection can be adjusted by the
removal of material from (machining) the contact
face of the cylinder block with the use of 8S3140
Cylinder Block Counterboring Tool Arrangement.
The instructions for the use of the tool group are in
Special Instruction Form No. FM055228.

CYLINDER BLOCK
The bore in the block for main bearings can be
checked with the main bearing caps installed without
bearings. Tighten the nuts holding the caps to the
torque shown in the SPECIFICATIONS. Align-
ment error in the bores must not be more than 0.08
mm (.003 in.). Special Instruction Form No.
SMHS7606 gives instructions for the use of 1P4000
Line Boring Tool Group for checking alignment of
the main bearing bores. 1P3537 Dial Bore Gauge
Group can be used to check the size of the bores.
Special Instruction Form No. GMG00981 is with
the group.

FLYWHEEL AND FLYWHEEL HOUSING
Installing Ring Gear
Heat the ring gear to install it. Do not heat to more
than 315°C (600°F). Install the ring gear so the
chamfer on the gear teeth are next to the starter
pinion when the flywheel is installed.
