Aiming Adjustment=NLEL0029Before performing aiming adjustment, make sure of the following.
1) Keep all tires inflated to correct pressure.
2) Place vehicle on level ground.
3) See that vehicle is unloaded (except for full levels of coolant,
engine oil and fuel, and spare tire, jack, and tools). Have the
driver or equivalent weight placed in driver's seat.
Adjust aiming in the vertical direction by turning the adjusting
screw.

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 on each cylinder as shown above.
+Always use a fully-charged battery to obtain specified
engine speed.
Compression pressure: kPa (bar, kg/cm
2, psi)/rpm
Standard
1,324 (13.24, 13.5, 192)/350
Minimum
1,128 (11.28, 11.5, 164)/350
Maximum allowable difference between cylinders
98 (0.98, 1.0, 14)/350
10. If cylinder compression in one or more cylinders is low, pour a
small amount of engine oil into the cylinder through the spark
plug hole and retest compression.
+If adding oil improves cylinder compression, piston rings
may be worn or damaged. If so, replace piston rings after
checking piston.
+If pressure stays low, a valve may be sticking or seating
improperly. Inspect and repair valve and valve seat. Refer
to SDS, EM-70. If valve or valve seat is damaged
excessively, replace them.
+If compression in any two adjacent cylinders is low and if add-
ing oil does not improve compression, there is leakage past the
gasket surface. If so, replace cylinder head gasket.
11. Reinstall spark plugs, ignition coils and fuel pump fuse.
12. Perform ªSelf-diagnosis Procedureº referring to EC-69, ªHow
to Erase DTCº if any DTC appears.

CAUTION:
+After removing timing chain, do not turn crankshaft and
camshaft separately, or valves will strike piston heads.
+When installing chain tensioner, oil seals, or other sliding
parts, lubricate contacting surfaces with new engine oil.
+Apply new engine oil to bolt threads and seat surfaces
when installing camshaft sprocket and crankshaft pulley.
+When removing oil pump assembly, remove camshaft
position sensor (PHASE), then remove timing chain from
engine.

WARNING:
+Position 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.
+Before disconnecting fuel hose, release pressure.
Refer to EC-43, ªFuel Pressure Releaseº.
+Be sure to lift engine and transaxle in a safe manner.
+For engines not equipped with engine slingers, attach
proper slingers and bolts described in PARTS CATALOG.
CAUTION:
+When lifting engine, be sure to clear surrounding parts.
Use special care near accelerator wire casing, brake lines
and brake master cylinder.
+When lifting the engine, always use engine slingers in a
safe manner.
+When removing drive shaft, be careful not to damage
grease seal of transaxle.
+Before separating engine and transaxle, remove crank-
shaft position sensor (POS) from the cylinder block
assembly.
+Always be extra careful not to damage edge of crankshaft
position sensor (POS), or signal plate teeth.
Engine cannot be removed separately from transaxle. Remove
engine with transaxle as an assembly.
