IAlign piston rings so that end gaps are positioned as
shown.
CRANKSHAFTNCEM0027S021. Install signal plate to crankshaft.
2. Set main bearings in their proper positions on cylinder block
and main bearing cap.
IConfirm that correct main bearings are selected by using
Method A or Method B. Refer to EM-57.
IApply new engine oil to bearing surfaces.
3. Install crankshaft and main bearing caps and tighten bolts to
the specified torque.
IApply new engine oil to the bolt thread and seat surface.
IPrior to tightening bearing cap bolts, shift crankshaft back
and forth to properly seat the bearing caps.
ITighten bearing cap bolts gradually in two or three stages.
Start with center bearing and move outward as shown in
figure.
IAfter securing bearing cap bolts, make sure crankshaft
turns smoothly by hand.

4. Measure crankshaft end play.
Crankshaft end play:
Standard
0.060 - 0.260 mm (0.0024 - 0.0102 in)
Limit
0.3 mm (0.012 in)
If beyond the limit, replace thrust bearing with new ones.
5. Install connecting rod bearings in connecting rods and con-
necting rod caps.
IConfirm that correct bearings are used. Refer to EM-58.
IInstall bearings so that oil hole in connecting rod aligns
with oil hole of bearing.
IApply new engine oil to bolt threads and bearing surfaces.
6. Install pistons with connecting rods.
a. Install them into corresponding cylinders with Tool.
IMake sure connecting rod does not scratch cylinder wall.
IMake sure connecting rod bolts do not scratch crankshaft
pin journals.
IArrange so that front mark on piston head faces engine.
IApply new engine oil to piston rings and sliding surface

Measurement of Compression Pressure
1. Warm up engine.
2. Turn ignition switch off.
3. Release fuel pressure.
Refer to ªReleasing Fuel Pressureº in EC-section.
4. Remove all spark plugs.
5. Disconnect distributor center cable.
6. Attach a compression tester to No. 1 cylinder.
7. Depress accelerator pedal fully to keep throttle valve wide
open.
8. Crank engine and record highest gauge indication.
9. Repeat the measurement for each cylinder.
IAlways use a fully-charged battery to obtain specified
engine revolution.
Compression pressure:
kPa (bar, kg/cm2, psi)/300 rpm
Standard 1,275 (12.75, 13.0, 185)
Minimum 1,079 (10.79, 11.0, 156)
Difference limit between cylinders 98 (0.98, 1.0, 14)
10. If cylinder compression in one or more cylinders is low:
A: pour a small amount of engine oil into cylinders through
spark plug holes.
B: retest compression.
IIf adding oil helps compression, piston rings may be worn
or damaged. If so, replace piston rings after checking pis-
ton condition.
IIf pressure stays low, a valve may be sticking or seating
badly. Inspect and repair valve and valve seat. (Refer to
SDS). If valve or valve seat is damaged excessively,
replace them.
IIf compression stays low in two cylinders that are next to
each other:
A. The cylinder head gasket may be leaking, or
B. Both cylinders may have valve component damage.
Inspect and repair as necessary.

Removal
1. Remove engine under cover.
2. Drain engine oil.
3. Remove steel oil pan bolts.
4. Remove steel oil pan.
a. Insert Tool between aluminum oil pan and steel oil pan.
IBe careful not to damage aluminum mating surface.
IDo not insert screwdriver, or oil pan flange will be
deformed.
