CAMSHAFT
3. With hexagonal part of camshaft locked with wrench, loosen
bolts securing camshaft sprocket to remove camshaft sprocket.
CAUTION:
 Do not loosen mounting bol ts with securing anything
other than the camshaft hexagonal portion or with ten-
sioning the timing chain.
 After removing timing chain, do not turn crankshaft and
camshaft separately, or valves will strike the piston head.
4. Remove intake and exhaust camshaft brackets.  Mark camshafts, camshaft brackets and bolts so placed in the same position and direction for installa-
tion.
 Equally loosen camshaft brackets and bolts in several steps in reverse order as shown in the figure.
 Lightly tapping with plastic hammer, remove camshaft bracket (No. 1) and camshaft bracket (No. 6).
NOTE:
The bottom surface of each bracket will be stuck to cylinder
head because of liquid gasket.
5. Remove camshaft.
6. Remove valve lifter if necessary.  Identify installation positions, and store them without mixing them up.
INSPECTION AFTER REMOVAL
Camshaft Runout
1. Put V-block on precise flat table, and support No. 2 and 5 journalof camshaft.
CAUTION:
Do not support journal No. 1 (on the side of camshaft
sprocket) because it has a differe nt diameter from the other
four locations.
2. Set dial indicator vertically to No. 3 journal.
3. Turn camshaft to one direction with hands, and measure the camshaft runout on dial indicator. (Total indicator reading)
4. If it exceeds the limit, replace camshaft.

 If corrected, measure the bearing oil clearance of the corrected main journal and/or pin journal. Then select
the main bearing and/or connecting rod bearing. Refer to "MAIN BEARING OIL CLEARANCE" and/or
"CONNECTING ROD BEARING OIL CLEARANCE".
CRANKSHAFT RUNOUT
 Place V-block on precise flat table, and support the journals on the both end of crankshaft.
 Place dial indicator straight up on the No. 3 journal.
 While rotating crankshaft, read the movement of the pointer on dial indicator. (Total indicator reading)
 If it exceeds the limit, replace crankshaft.
CONNECTING ROD BEARING OIL CLEARANCE
Method by Calculation
 Install connecting rod bearings to connecting rod and cap, and tighten connecting rod bolts to the specified torque. Refer to EM-
242, "Disassembly and Assembly" for the tightening procedure.
 Measure the inner diameter of connecting rod bearing with inside micrometer.
(Bearing oil clearance) = (Connecting rod bearing inner diameter) –
(Crankshaft pin journal diameter)
 If the calculated value exceeds the limit, select proper connecting rod bearing according to connecting rod
big end diameter and crankshaft pin journal diameter to obtain the specified bearing oil clearance. Refer to
EM-250, "
How to Select Piston and Bearing".
Method of Using Plastigage
 Remove oil and dust on crankshaft pin journal and the surfaces of each bearing completely.
 Cut plastigage slightly shorter than the bearing width, and place it in crankshaft axial direction, avoiding oil
holes.
 Install connecting rod bearings to connecting rod and cap, and tighten connecting rod bolts to the specified
torque. Refer to EM-242, "
Disassembly and Assembly" for the tightening procedure.
CAUTION:
Do not rotate crankshaft.
 Remove connecting rod bearing cap and bearing, and using scale
on plastigage bag, measure the plastigage width.
NOTE:
The procedure when the measured value exceeds the limit is
same as that described in the “Method by Calculation”.

tightening procedure.
 Measure the inner diameter of main bearing with bore gauge.
(Bearing clearance) = (Main bearing inner diamet er) – (Crankshaft main journal diameter)
 If the calculated value exceeds the limit, select proper main bearing according to main bearing inner diame-
ter and crankshaft main journal diameter to obtain the specified bearing oil clearance. Refer to EM-250,
"How to Select Piston and Bearing".
Method of Using Plastigage
 Remove oil and dust on crankshaft main journal and the surfaces of each bearing completely.
 Cut plastigage slightly shorter than the bearing width, and place it in crankshaft axial direction, avoiding oil
holes.
 Install main bearings to cylinder block and main bearing caps, and tighten main bearing bolts with main bear- ing to the specified torque. Refer to EM-242, "

CAUTION:
Do not rotate crankshaft.
 Remove main bearing caps and bearings, and using scale on plas- tigage bag, measure the plastigage width.
NOTE:
The procedure when the measured value exceeds the limit is
same as that described in the “Method by Calculation”.
CRUSH HEIGHT OF MAIN BEARING
 When main bearing cap is removed after being tightened to the specified torque with main bearings installed, the tip end of bearing
must protrude. Refer to EM-242, "

SERVICE INFORMATION FOR ELECTRICAL INCIDENT
 Cold or hot start up
Get a thorough description of the incident from the customer. It is important for simulating the conditions of the
problem.
Vehicle Vibration
The problem may occur or become worse while drivi ng on a rough road or when engine is vibrating (idle with
A/C on). In such a case, you will want to check for a vi bration related condition. Refer to the following illustra-
tion.
CONNECTORS & HARNESS
Determine which connectors and wiring harness would affect the electrical system you are inspecting. Gently
shake each connector and harness while monitoring the sy stem for the incident you are trying to duplicate.
This test may indicate a loose or poor electrical connection.
HINT
Connectors can be exposed to moisture. It is possible to get a thin film of corrosion on the connector termi-
nals. A visual inspection may not reveal this without disconnecting the connector. If the problem occurs inter-
mittently, perhaps the problem is caused by corrosion. It is a good idea to disconnect, inspect and clean the
terminals on related connectors in the system.
SENSORS & RELAYS
Gently apply a slight vibration to sensors and relays in the system you are inspecting.
This test may indicate a loose or poorly mounted sensor or relay.
ENGINE COMPARTMENT
There are several reasons a vehicle or engine vibration could cause an e\
lectrical complaint. Some of the
things to check for are:
 Connectors not fully seated.
 Wiring harness not long enough and is being stressed due to engine vibrations or rocking.
 Wires laying across brackets or moving components.
 Loose, dirty or corroded ground wires.
 Wires routed too close to hot components.
To inspect components under the hood, start by verifyi ng the integrity of ground connections. (Refer to Ground
Inspection described later.) First check that the system is properly grounded. Then check for loose connection
by gently shaking the wiring or components as previous ly explained. Using the wiring diagrams inspect the
wiring for continuity.
BEHIND THE INSTRUMENT PANEL
An improperly routed or improperly clamped harness can become pinched during accessory installation. Vehi-
cle vibration can aggravate a harness which is routed along a bracket or near a screw.
UNDER SEATING AREAS
An unclamped or loose harness can cause wiring to be pinched by seat components (such as slide guides)
during vehicle vibration. If the wiring runs under s eating areas, inspect wire routing for possible damage or
pinching.
