For further air bleeding, crank engine while operating priming
pump up and down. Do not crank engine more than 10 seconds
at a time.

Amount of cylinder block resurfacing is ªBº.
The maximum limit:A+B=0.07 mm (0.0028 in)
After resurfacing cylinder head, check that camshaft rotates
freely by hand. If resistance is felt, cylinder head must be
replaced.
Nominal cylinder head height:
153.9 - 154.1 mm (6.059 - 6.067 in)
CAMSHAFT VISUAL CHECK
Check camshaft for scratches, seizure and wear.
CAMSHAFT RUNOUT
1. Place V-blocks on a work bench and support camshaft at No.
1 and No. 5 journal.
2. Set dial gauge perpendicularly at camshaft No. 3 journal.
3. Turn camshaft by hand in one direction and read runout on
dial gauge.
Runout (Total indicator reading):
Limit 0.02 mm (0.0008 in)
4. If it exceeds the limit, replace camshaft.
CAMSHAFT CAM HEIGHT
1. Measure camshaft cam height.
Standard cam height:
Intake
39.505 - 39.695 mm (1.5553 - 1.5628)
Exhaust
39.905 - 40.095 (1.5711 - 1.5785)
Cam wear limit:
0.15 mm (0.0059 in)
2. If wear is beyond the limit, replace camshaft.
CAMSHAFT JOURNAL CLEARANCE
1. Install camshaft bracket and tighten bolts to the specified
torque.
2. Measure inner diameter of camshaft bearing.
Standard inner diameter:
No. 1: 30.500 - 30.521 mm (1.2008 - 1.2016 in)
No. 2, 3, 4, 5: 24.000 - 24.021 mm (0.9449 - 0.9457

WARNING:
+Situate vehicle on a flat and solid surface.
+Place chocks at front and back of rear wheels.
+Do not remove engine until exhaust system has com-
pletely cooled off. Otherwise, you may burn yourself
and/or fire may break out in fuel line.
+Be sure to hoist engine and transmission in a safe man-
ner.
+For engines not equipped with engine slingers, attach
proper slingers and bolts described in PARTS CATA-
LOG.
CAUTION:
+When lifting engine, be careful not to strike adjacent
parts, especially the following: Accelerator wire casing,
brake lines, and brake master cylinder.
+In hoisting the engine, always use engine slingers in a
safe manner.
+For 4WD models, apply sealant between engine and
transmission. Refer to MT section (ªRemoval and Instal-
lationº).
+For tightening torque, refer to M/T and PD sections.
+Before separating engine and transmission, remove the
crankshaft position sensor (TDC sensor) from the
assembly.
+Always pay extra attention not to damage edge of crank-
shaft position sensor (TDC sensor) or ring gear teeth.

round.
Out-of-round (X þ Y):
Standard
0.003 mm (0.0001 in)
Limit
0.005 mm (0.0002 in)

Limit
0.005 mm (0.0002 in)
3. Measure crankshaft runout at No. 3 (center) journal.
Runout (Total indicator reading):
Standard 0.05 mm (0.0020 in)
Limit 0.10 mm (0.0039 in)
MAIN BEARING HOUSING INNER DIAMETER
+Without installing main bearings, install main bearing caps,
and tighten bolts to the specified torque.
+Measure the inner diameter of main bearing housing with a
bore gauge.
Standard:
66.654 - 66.681 mm (2.6242 - 2.6252 in) dia.
+If the measurement is out of the specified range, replace
cylinder block and main bearing caps.
BEARING CLEARANCE
+Use either of the following two methods, however, method
ªAº gives more reliable results and is preferable.
Method A (Using bore gauge & micrometer)
Main bearing
1. Install main bearings to the cylinder block and bearing cap,
and tighten the bolts to the specified torque. Then, measure
the inner diameter of the main bearings.
