Diagnostic Procedure 2 (Cont'd)
HA-42

Maintenance of Lubricant Quantity in
Compressor
The lubricant used to lubricate the compressor circulates through
the system with the refrigerant. Add lubricant to compressor
when replacing any component or after a large gas leakage
occurred. It is important to maintain the specified amount.
If lubricant quantity is not maintained properly, the following mal-
functions may result:
lLack of lubricant: May lead to a seized compressor
lExcessive lubricant: Inadequate cooling (thermal exchange
interference)
LUBRICANT
Name: Nissan A/C System Oil Type R
Part number: KLH00-PAGR0
CHECKING AND ADJUSTING
Adjust the lubricant quantity according to the flowchart shown
below.
START
Can lubricant return operation be per-
formed?
lA/C system works properly.lThere is no evidence of a large amount of
lubricant leakage.
No
cYes
Perform lubricant return operation, proceeding as follows:
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
1. Start engine, and set the following conditions:
lTest condition
Engine speed: Idling to 1,200 rpm
A/C or AUTO switch: ON
Blower speed: Max. position
Temp. control: Optional [Set so that intake air temperature is
25 to 30ÉC (77 to 86ÉF).]
2. Next item is for V-5 or V-6 compressor. Connect the manifold
gauge, and check that the high pressure side pressure is 588 kPa
(5.9 bar, 6 kg/cm
2, 85 psi) or higher.
If less than the reference level, attach a cover to the front face of
the condenser to raise the pressure.
3. Perform lubricant return operation for about 10 minutes.
4. Stop engine.
CAUTION:
If excessive lubricant leakage is noted, do not perform the lubricant
return operation.
Should the compressor be replaced?
No Yes
b
VA(Go to next page.)
Is there any part to be replaced?
(Evaporator, condenser, liquid tank or in
case there is evidence of a large amount of
lubricant leakage.)
No
cYes
After replacing any of the following major components, add the correct
amount of lubricant to the system.
Amount of lubricant to be added
*1: If compressor is replaced, addition of lubricant is included in the flow
chart.
*2: If refrigerant leak is small, no addition of lubricant is needed.
Carry out the A/C performance test.b

Changing Oil Filter
1. Remove oil filter with a suitable tool.
WARNING:
Be careful not to burn yourself, as the engine and the engine
oil are hot.
2. Before installing a new oil filter, clean the oil filter mounting
surface on cylinder block, and coat the rubber seal of oil fil-
ter with a little engine oil.
3. Screw in the oil filter until a slight resistance is felt, then
tighten additionally more than 2/3 turn.
4. Add engine oil.
Refer to ``Changing Engine Oil'', MA-19.
Checking and Changing Spark Plugs
1. Disconnect ignition wires from spark plugs at boot.
Do not pull on the wire.
2. Remove spark plugs with spark plug wrench.
3. Clean plugs in sand blast cleaner.
4. Check insulator for cracks or chips, gasket for damage or
deterioration and electrode for wear and burning. If they are
excessively worn away, replace with new spark plugs.

lTighten lock nuts, by fixing the adjusting screws using a
minus driver.
Checking Drive Belt
1. Inspect for cracks, fraying, wear or oil adhesion. Replace if
necessary.
The belts should not touch the bottom of the pulley groove.
2. Check drive belt deflection by pushing on the belt midway
between pulleys.
Adjust if belt deflections exceed the limit.
