1999 NISSAN PRIMERA alternator belt

Trouble Diagnoses
Before conducting an alternator test, make sure that the battery is fully charged. A 30-volt voltmeter and
suitable test probes are necessary for the test. The alternator can be checked easily by referring to the
Inspection Table.

Before starting, inspect the fusible link.

Use fully charged battery.

Note:

If the inspection result is OK even though the charging system is malfunctioning, check the B
terminal connection. (Check the tightening torque.)

When field circuit is open, check condition of rotor coil, rotor slip ring and brush. If necessary,
replace faulty parts with new ones.
MALFUNCTION INDICATOR
The IC regulator warning function activates to illuminate“CHARGE”warning lamp, if any of the following
symptoms occur while alternator is operating:

Excessive voltage is produced.

No voltage is produced.

Removal and Installation
1. Loosen lock bolt.
2. Remove RH undertray.
3. Loosen alternator mounting bolt and remove drive belt.
4. Remove lock bolt and adjust.
5. Remove harness connectors.
6. Remove alternator mounting bolt.
7. Support engine with jack, and remove front engine mounting
bolt.
8. Remove alternator.
Disassembly
REAR COVER
CAUTION:
Rear cover may be hard to remove because a ring is used
to lock outer race of rear bearing. To facilitate removal of
rear cover, heat bearing box section with a 200W soldering
iron.
Do not use a heat gun, as it can damage diode assembly.
REAR BEARING
CAUTION:

Do not reuse rear bearing after removal. Replace with a
new one.

Do not lubricate rear bearing outer race.
Inspection
ROTOR CHECK
1. Resistance test
Resistance: Refer to SDS (EL-63).

Not within the specified values ... Replace rotor.
2. Insulator test

Continuity exists ... Replace rotor.
3. Check slip ring for wear.
Slip ring minimum outer diameter:
Refer to SDS (EL-63).

Not within the specified values ... Replace rotor.

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

WARNING:
IPosition vehicle on a flat and solid surface.
IPlace chocks at front and back of rear wheels.
IDo not remove engine until exhaust system has com-
pletely cooled;
Otherwise, you may burn yourself and/or fire may break
out in fuel line.
IBefore disconnecting fuel hose, release fuel pressure
from fuel line.
Refer to ªReleasing Fuel Pressureº in EC section.
IBe sure to hoist engine and transaxle in a safe manner.
IFor engines not equipped with engine slingers, attach
slingers and bolts described in PARTS CATALOG.
CAUTION:
IWhen lifting engine, be sure to clear surrounding parts.
Use special care for accelerator cable, brake lines and
brake master cylinder.
IIn hoisting the engine, always use engine slingers in a
safe manner.
IWhen removing drive shaft, be careful not to damage
grease seal of transaxle.
Removal
1. Remove engine under cover and hood.
2. Drain coolant from both cylinder block, and radiator.
3. Drain engine oil.
4. Remove vacuum hoses, fuel hoses, wires, harness and con-
nectors.
5. Remove exhaust tubes, ball joints and drive shafts.
6. Remove radiator and fans.
7. Remove drive belts.
8. Remove alternator, compressor and power steering oil pump
from engine.
9. Set a suitable transmission jack under transaxle. Hoist engine
with engine slinger.
10. Remove center member.

Checking Drive Belts
1. Inspect belt for cracks, fraying, wear and oil. If necessary,
replace.
2. Inspect drive belt deflection or tension at a point on the belt
midway between pulleys.

Inspect drive belt deflection or tension when engine is
cold.

Adjust if belt deflection exceeds the limit or if belt ten-
sion is not within specifications.

Turn crankshaft two revolutions and recheck drive belt
deflection or tension.

WARNING:
To avoid being scalded, never change the coolant when the
engine is hot.

—DRAINING ENGINE COOLANT—
1. Set heater system as follows to prevent coolant from remain-
ing in the system.

Move temperature control dial all the way to“HOT”.
Semi-automatic air conditioning
1. Set air conditioner system as follows to prevent coolant from
remaining in the system.
a. Turn ignition switch“ON”and enter a temperature of 32°Con
