(2) Apply engine oil to crankshaft journal and pin and install crank-shaft.
(3) Install main bearings caps.
a) Install main bearing cap with the lowest number facing the front of vehicle.
b) Apply engine oil to main bearing cap and cylinder block contact surfaces.
c) Install rear oil seal assembly. Apply engine oil to contact surface of rear end oil seal and crankshaft.
(4) Install crankshaft thrust washer at the 4th journal from front.
Install thrust washer so that oil groove can face crankshaft.
(5) Tighten bearing cap bolts gradually in stages, starting from two to three separate stages, from center bearing and moving out-
ward in sequence.
(6) Measure crankshaft free end play at No. 4 bearing. Crankshaft free end play:Standard0.060 - 0.25 mm (0.0024 - 0.0098 in)
Limit 0.4 mm (0.016 in)
If beyond the limit, replace No. 4 main bearing thrust washer. Refer to SDS.

Liquid Gasket Application Procedure
a. Use a scraper to remove all traces of old liquid gasket frommating surfaces and grooves. Also, completely clean any oil
from these areas.
b. Apply a continuous bead of liquid gasket to mating surfaces. (Use Genuine Liquid Gasket or equivalent.)
IFor oil pan, be sure liquid gasket diameter is 3.5 to 4.5 mm
(0.138 to 0.177 in).
I For areas except oil pan, be sure liquid gasket diameter is
2.0 to 3.0 mm (0.079 to 0.118 in).
c. Apply liquid gasket around the inner side of bolt holes (unless otherwise specified).
d. Assembly should be done within 5 minutes after coating.
e. Wait at least 30 minutes before refilling engine oil and engine coolant.

Oil Pressure Check
WARNING:
IBe careful not to burn yourself, as the engine and oil may
be hot.
I Oil pressure check should be done in ªNeutralº gear posi-
tion.
1. Check oil level.
2. Remove oil pressure switch.
3. Install pressure gauge.
4. Start engine and warm it up to normal operating temperature.
5. Check oil pressure with engine running under no-load.
Engine speed
rpm Approximate discharge pressure
kPa (bar, kg/cm2, psi)
Idle speed 2,000
4,000 More than 147 (1.47, 1.5, 21)
More than 539 (5.39, 5.5, 78)
More than 736 (7.36, 7.5, 107)
If difference is extreme, check oil passage and oil pump.
6. Install oil pressure switch with sealant. Oil pressure switch:
:13-17N ×m (1.25 - 1.75 kg-m ,9-12ft-lb)
