15. Measure ring gear-to-drive pinion backlash with a dial indicator. Ring gear-to-drive pinion backlash:0.13 - 0.18 mm (0.0051 - 0.0071 in)
I If backlash is too small, decrease thickness of right shim and
increase thickness of left shim by the same amount.
If backlash is too great, reverse the above procedure.
Never change the total amount of shims as it will change the
bearing preload.

HFC-134a (R-134a) Service Tools and
Equipment
It is important to understand that HFC-134a (R-134a) refrigerant, and the specified lubricant which must be
used with HFC-134a (R-134a), must never be mixed with CFC-12 (R-12) refrigerant and/or the CFC-12 (R-12)
lubricant.
This means that separate and non-interchangeable service equipment must be used for handling each type
of refrigerant/lubricant.
To prevent the mixing of refrigerants/lubricants, refrigerant container fittings, service hose fittings, and service
equipment fittings (equipment which handles refrigerant and/or lubricant) are different between CFC-12 (R-12)
and HFC-134a (R-134a).
Adaptors to convert from one size of fitting to another must never be used: refrigerant/lubricant contamination
will occur and compressor failure will result.

Lubrication Oil
Name: Nissan A/C System Oil Type S
Part number: KLH00-PAGS0
Maintenance of Oil Quantity in Compressor
The oil used to lubricate the compressor circulates through the
system with the refrigerant. Whenever any component of the sys-
tem is replaced or a large amount of gas leakage occurs, add oil
to the compressor to maintain the specified amount.
If oil quantity is not maintained properly, the following malfunctions
may result:
ILack of oil: May lead to a seized compressor
I Excessive oil: Inadequate cooling (thermal exchange impeded)
Checking and Adjusting
Adjust the oil quantity according to the flowchart shown below.
START
Can oil return operation be performed?
IA/C system works properly.
I There is no evidence of a large amount
of oil leakage.
No
EYe s
Perform oil return operation, proceeding as follows:
------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- 1. Start engine, and set the following conditions:
I Test 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. Perform oil return operating for about 10 minutes.
3. Stop engine.
CAUTION:
If excessive oil leakage is noted, do not perform the oil return operation.
Should the compressor be replaced?
No Yes
qA(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 oil leakage.)
No
EYe s After replacing any of the following major components of the system, be sure
to add the correct amount of oil to the system.
Amount of oil to be added
*1: If compressor is replaced, addition of oil is included in the flow chart.
*2: If refrigerant leak is small, no addition of oil is needed. ªRatioº in this table indicates the ratio of added oil to the overall amount of oil needed in the
system.
Carry out the A/C performance test.F
