DTC 25 Driver Deployment Loop Short To B+
CAUTION: When DTC 25 has been set, it is necessary to replace the SDM. Setting DTC 25 will also cause DTC
71 to set. When a scan tool “CLEAR CODES” command is issued and the malfunction is no longer present,
DTC 71 will remain current. Ensure that the short to B+ condition is repaired prior to installing a replacement
SDM to avoid damaging the SDM.

COMPRESSOR CLUTCH PLATE AND HUB
ASSEMBLY
Removal
1. Clamp the holding fixture J-33026 in a vise and
attach compressor to holding fixture with thumb
screws J-33026-1.
2. With center screw forcing tip in place to thrust
against the end of the shaft, thread the Clutch Plate
and Hub Assembly Installer-Remover J-33013-B into
the hub. Hold the body of the remover with a wrench
and turn the center screw into the remover body to
remove the clutch plate and hub assembly (1).
CAUTION: Do not drive or pound on the clutch hub
or shaft. Internal damage to compressor may
result. The forcing tip on J-33013-B remover-
installer center screw must be flat or the end of the
shaft/axial plate assembly will be damaged.
3. Remove the shaft key and retain for reassembly.
Installation
1. Install the shaft key into the hub key groove. Allow
the key to project approximately 3.2 mm (1/8 in) out
of the keyway. The shaft key is curved slightly to
provide an interference fit in the hub key groove.2. Be sure the frictional surface of the clutch plate and
the clutch rotor (2) are clean before installing the
clutch plate and hub assembly (1).
3. Align the shaft key (4) with the shaft keyway (3) and
place the clutch plate and the hub assembly onto
the compressor shaft.
4. Remove the forcing tip on J-33013-B clutch plate
and hub assembly installer-remover center screw
and reverse the body direction on the center screw,
as shown in Figure.
5. Install the clutch plate and hub installer-remover J-
33013-B with bearing as shown in Figure.
The body of the J-33013-B installer-remover should
be backed off sufficiently to allow the center screw to
be threaded onto the end of the compressor shaft.
6. Hold the center screw with a wrench. Tighten the
hex portion of the installer-remover J-33013-B body
to press the hub onto the shaft. Tighten the body
several turns, remove the installer and check to see
that the shaft key is still in place in the keyway
before installing the clutch plate and hub
assembly to its finial position.The air gap (2)
between frictional surfaces of the clutch plate and
clutch rotor should be 0.50–0.76 mm (.020–.030 in).

7. Remove and discard the seal seat O-ring (2) from the
compressor neck using O-ring remover J-9553-01.
8. Recheck the shaft and inside of the compressor
neck for dirt or foreign material and be sure these
areas are perfectly clean before installing new parts.
Cleaning
Thoroughly clean O-ring seal groove in front head.
CAUTION: Seals should not be re-used. Always use
a new specification service seal on rebuild. Be sure
that the seal to be installed is not scratched or
damaged in anyway. Make sure that the seal seat
and seal are free of lint and dirt that could damage
the seal surface or prevent sealing.
Installation
1. Dip the new seal seat O-ring (1) in clean 525
viscosity refrigerant oil and assemble onto O-ring
installer J-33011.2. Insert the O-ring installer J-33011 into the
compressor neck until the installer "bottoms". Lower
the moveable slide of the O-ring installer to release
the O-ring into the seal O-ring lower groove (The
compressor neck top groove is for the shaft seal
retainer ring.) Rotate the installer to seat the O-ring
and remove the installer.
3. Dip the new seal in clean 525 viscosity refrigerant oil
and assemble seal to Seal Installer J-23128-A, by
turning handle clockwise. The stamped steel case
side of the lip seal must be engaged with knurled
tangs of installer so that flared-out side of lip seal is
facing and installed towards the compressor. Install
seal protector J-34614, in the seal lip and place over
the compressor shaft, and push the seal in place with
a rotary motion or place the seal protector J-34614
over end of compressor shaft, and slide the new seal
onto the shaft with a rotary motion until it stops. Take
care not to dislodge the O-ring. Be sure the seal (2)
makes good contact with the O-ring. Disengage the
installer from the seal and remove the installer
J-23128-A and the seal protector J-34614.
CAUTION: Handling and care of seal protector is
important. If seal protector is nicked or the bottom
flared, the new seal may be damaged during
installation.
4. Install the new seal retainer ring with its flat side
against the Seal, using Snap-Ring Pliers. Use the
sleeve from O-ring installer J-33011 to press in on
the seal retainer ring so that it snaps into its groove.
5. To leak test, install compressor leak test fixture
J-39893 on rear head of compressor and connect
gage charging lines and Refrigerant Recovery
System. Pressurize suction and high-side of
compressor with R-134a Refrigerant. Temporarily
install (M9
1.25 thread on shaft) nut and, with the
compressor in horizontal position, rotate the
compressor shaft in normal direction of rotation
several times by hand. Leak test the seal area and
correct and leak found. Recover the refrigerant.
Remove shaft nut.
