1. REMOVE REAR OIL SEAL RETAINER
(a) Remove the 6 bolts.
(b) Remove the oil seal retainer by prying the area between the
oil seal retainer and main bearing cap with a screwdriver.
2. CHECK CONNECTING ROD THRUST CLEARANCE
Using a dial indicator, measure the thrust clearance while
moving the connecting rods back and forth.
Standard thrust clearance:
0.250±0.402 mm (0.0098±0.0158 in.)
Maximum thrust clearance:
0.50 mm (0.0197 in.)
If the thrust clearance is greater than maximum, replace the
connecting rod assembly(s). If necessary, replace the crank-
shaft.
Connecting rod thickness:
25.898±25.950 mm (1.0196±1.0217 in.)
3. REMOVE CONNECTING ROD CAPS AND CHECK OIL
CLEARANCE
(a) Check the matchmarks on the connecting rod and cap to
ensure correct reassembly.
± ENGINEENGINE MECHANICALEG±99
Page 1414 of 2543
(b) Remove the connecting rod cap bolts.
(c) Using the 2 removed connecting rod bolts, remove the
connecting rod cap and lower bearing by wiggling the
connecting rod cap right and left.
HINT: Keep the lower bearing inserted with the connecting
rod cap.
(d) Clean the crank pin and bearings.
(e) Check the crank pin and bearing for pitting and scratches.
If the crank pin or bearing is damaged, replace the bearings.
If necessary, replace the crankshaft.
(f) Lay a strip of Plastigage across the crank pin.
(g) Install the connecting rod cap with the 2 bolts.
(See step 8 in cylinder block assembly)
Torque:

NOTICE: Do not turn the crankshaft.
(h) Remove the 2 bolts, connecting rod cap and lower bearing.

(i) Measure the Plastigage at its widest point.
Standard oil clearance:
STD
.035±0.053 mm (0.0014±0.0021 in.)
U/S 0.25
.040±0.078 mm (0.0016±0.0031 in.)
Maximum oil clearance.
STD
.08 mm (0.0031 in.)
U/S 0.25
.09 mm (0.0035 in.)
If the oil clearance is greater than maximum, replace the
bearings. If necessary, grind or replace the crankshaft.
HINT: If using a standard bearing, replace with one having
the same number. If the number of the bearing cannot be de-
termined, select the correct bearing by adding together the
numbers imprinted on the connecting rod cap and crank-
shaft, then selecting the bearing with the same number as the
total. There are 5 sizes of standard bearings, marked º1º, º2º,
º3º, º4º and º5º accordingly.

the cylinder.
(b) Push the piston, connecting rod assembly and upper bearing
through the top of the cylinder block.
HINT:
wKeep the bearings, connecting rod and cap together.
wArrange the piston and connecting rod assemblies in
correct order.
5. CHECK CRANKSHAFT THRUST CLEARANCE
Using a dial indicator, measure the thrust clearance while pry-
ing the crankshaft back and forth with a screwdriver.
Standard thrust clearance:
0.020±0.220 mm (0.0008±0.0087 in.)
Maximum thrust clearance:
0.30 mm (0.0118 in.)

6. REMOVE MAIN BEARING CAPS AND CHECK OIL
CLEARANCE
(a) Uniformly loosen and remove the 14 main bearing cap bolts,
in severval passes, in the sequence shown.
