2014-2015 TAXI; AIR CONDITIONING
COMPRESSOR CLUTCH REPLACEMENT
APPLIED VEHICLE:
2014-2015 Taxi
IF YOU CONFIRM
The “air conditioning” (A/C) compressor clutch needs to be replaced.
ACTION
1. Remove the A/C compressor assembly from the vehicle.
2. Inspect the A/C compressor refrigerant oil condition.

If the A/C compressor refrigerant oil is BROWN, replace the A/C compressor
assembly.

If the A/C compressor refrigerant oil is LIGHT GREEN and does not have any
foreign materials replace only the A/C compressor clutch.
IMPORTANT: The purpose of ACTION (above) is to give you a quick idea of the work you will be
performing. You MUST closely follow the SERVICE PROCEDURE (on page 2) as it contains
information that is essential to successfully completing this repair.
Nissan Bulletins are intended for use by qualified technicians, not 'do-it-yourselfers'. Qualified technicians are
properly trained individuals who have the equipment, tools, safety instruction, and know-how to do a job
properly and safely. NOTE: If you believe that a described condition may apply to a particular vehicle, DO
NOT assume that it does. See your Nissan dealer to determine if this applies to your vehicle.

SERVICE PROCEDURE
A/C COMPRESSOR REMOVAL
1. Evacuate the system’s refrigerant.

Record the amount evacuated.
NOTE: Make sure your Robinair/Tech-Mate Air-Conditioning Machine # 48710 is
calibrated.

If the amount initially evacuated was less than 600 grams (1.32 pounds), check for
leaks and repair as needed.
2. Place the vehicle on a lift and remove the right front wheel.
3. Partially remove the front fender protector (RH).
4. Remove the front under cover.
5. Remove the drive belt from the A/C
compressor.
NOTE: Complete removal of the drive
belt is not necessary.
Bolt
6. Remove the bolt (Figure 1) that retains
the high-pressure flexible hose to the
A/C compressor.
CAUTION: Cap or wrap the joint of the
pipe with a suitable material such as vinyl
tape to avoid the entry of air.
Figure 1
7. Remove the bolt (Figure 2) that retains
the low-pressure flexible hose to the A/C
compressor.
Bolt
CAUTION: Cap or wrap the joint of the
pipe with a suitable material such as vinyl
tape to avoid the entry of air.
8. Disconnect the harness connector from
the A/C compressor.

9. Remove the A/C compressor bolts and then A/C compressor from the vehicle
(Figure 3).
CAUTION:
 Do not reuse O-rings.
 Apply A/C oil to new O-rings for installation.
 Tighten compressor bolts to specification.

COMPRESSOR CLUTCH OIL CONDITION INSPECTION
1. Inspect a sample of the compressor
refrigerant oil.
2. Is the refrigerant oil green as shown in
Figure 4?
YES: Proceed to A/C CLUTCH
REPLAEMENT on page 4.
NO: Replace the A/C compressor
assembly and then proceed to A/C

A/C CLUTCH REPLACEMENT
1. Remove the center bolt by holding the
A/C compressor clutch disc steady using
a suitable tool.
2. Remove the compressor clutch disc and
shims.
CAUTION: Retain all of the shims for
installation.
3. Remove the snap ring using a suitable
tool as shown (Figure 5).
Figure 5
4. Remove the compressor pulley assembly
using a suitable tool (A) as shown
(Figure 6).
CAUTION: To prevent deformation of
the pulley groove, the puller claws
should be hooked under (not into) the
pulley groove.

5. Remove the three magnet coil screws
using a suitable tool as shown, and then
remove the magnet coil.

Magnet Coil Inspection
Replace the magnet coil if any of the following symptoms are found:



If the clutch disc contact surface shows signs of damage due to excessive heat.
If the contact surface of the pulley shows signs of excessive grooving.
If the magnet coil contains cracked insulation or a loose connection.
6. Install the magnet coil by aligning the
magnet coil pin (A) with the hole (B) in
the A/C compressor front head as shown,
then install the magnet coil screws.
CAUTION: Make sure to align the
magnet coil pin with the hole in the A/C
compressor front head.

7. Install the new pulley assembly using
the Tool and a wrench as shown, and
then install the snap ring using a suitable
tool.

Tool number (J-38873-A)

8. Install the new clutch disc (1) on the
drive shaft, together with all of the
original shim(s) (2) using a suitable tool
(A).
9. Install the center bolt using a suitable tool.

After tightening the center bolt to
specification, check that the pulley
rotates smoothly.

10. Check the clearance (B) all the way
around between the clutch disc (1) and
pulley (2) using a suitable tool (A) as
shown.

Clutch disc-to-pulley clearance (B)
0.3 - 0.6 mm (0.012 - 0.024 in)
11. If the specified clearance (B) is not
obtained, replace the adjusting shim(s)
and recheck the clearance (B) as shown.
A/C COMPRESSOR INSTALLATION
Figure 12
1. Install the compressor onto the vehicle.
2. Re-connect the harness connector to the compressor.
3. Confirm that the power steering line is in the correct position; do not disconnect the
power steering line.
4. Install the drive belt.
5. Install the front under cover.
6. Install the front fender protector (RH).
7. Install the wheel.
8. Recharge the refrigerant.
NOTE: Do not use the charge capacity value listed in the Taxi ESMs.


Ideal refrigerant charge amount: 750 grams (1.65 pounds)
Acceptable charge amount: 700 grams +/- 50 grams (1.54 pounds +/- 0.11 pounds)
BREAK-IN OPERATION
When replacing compressor clutch assembly, always conduct the break-in operation. This
is done by engaging and disengaging the clutch about 30 times. Break-in operation raises
the level of transmitted torque.
