1999 Silverado A/c

[daljo]

Has anyone changed the A/C clucth on a 1999 Silverado, should be same 99-02.

 

The clutch tools are list Applications: GM V5, DA6, and HR6. I did some searching and it lists my compressor as a HU6. Does this same tool fit to pull the clutch?

Removal & Installation

Delphi/Harrison

To Remove:

 

Clamp a J 34992 or appropriate holding fixture in a vise.

Use thumb screws in order to attach the compressor to the holding fixture.

NOTE: Do not drive or pound on the clutch hub or shaft. Internal damage to the compressor may result.

 

 

Compressor clutch plate and hub assembly

 

 

 

 

Ensure that the center screw forces the tip to thrust against the end of the shaft.

Thread a J 33013-B remover/installer tool or equivalent onto the hub.

While holding the body of the remover with a wrench, turn the center screw into the remover body in order to remove the clutch plate and hub assembly (1).

Remove the shaft key.

Retain the shaft key for reassembly.

Remove the rotor and bearing assembly retaining ring.

Install the J 33023-A to the front head.

 

Use the pulley puller J33020 to remove the rotor and bearing assembly

 

 

 

 

Install the J 33020 into the inner circle of slots in the rotor.

Turn the J 33020 clockwise in the slots in order to engage the tangs of the puller with the segments between the slots in the rotor.

Hold the J 33020 in place. Tighten the puller screw against the guide to remove the puller rotor and bearing assembly.

Mark the location of the clutch coil terminal on the compressor front head.

Install the J 33023-A on the front head of the compressor.

Install the J 8433-1 and J 8433-3 with J 33025 on the compressor.

Tighten the J 8433-3 against the J 33023-A in order to remove the clutch coil.

 

 

 

 

 

 

To Install:

 

Place the clutch coil assembly on the compressor with the terminals positioned at the marked location.

Place the J 33024 over the internal opening of the clutch coil housing.

Align the J 33024 with the compressor front head.

Center the J 8433-1 on the countersunk center hole of the J 33024.

Install the through bolts and washers of the J 34992 through the slots in the J 8433-1.

Thread the through bolts into the J 33025 in order to achieve full fixture thickness.

NOTE: Make sure that the clutch coil and the J 33024 stay in-line during the installation.

 

Turn the J 8433-3 of the J 8433-1 in order to force the clutch coil onto the head.

With the compressor still mounted to the J 34992 and the coil seated on the front head, stake the front head using a drift punch with a diameter of 0.125 in (3.175 mm).

Stake the front head at 3 places 120 degrees apart in order to ensure that the clutch coil remains in position. Ensure that the stake size is only one half of the area of the punch tip and only 0.010-0.015 in (0.28-0.35 mm) in depth.

With the compressor mounted to the holding fixture, position the rotor and bearing assembly on the front head.

Position the J 33017 and the J 33023-A directly over the inner race of the bearing.

Position the J 8433-1 on the J 33023-A.

Assemble the 2 through bolts and the washers of the holding fixture through the slots of the J 8433-1.

Thread the bolts into the holding fixture. Make sure that the thread of the through bolts engages the full thickness of the J 34992.

Tighten the J 8433-3 in the J 8433-1 in order to force the pulley rotor and bearing assembly onto the front of the compressor.

If the J 33017 slips off direct, in-line contact with inner face of the bearing, perform the following:

Loosen the J 8433-3

Realign the J 33017 and the J 33023-A to ensure that the installer clears the front head.

Install the rotor and bearing assembly retainer ring.

Install the shaft key into the hub key groove.

Allow the key to project approximately 3.2 mm (0.125 in) out of the keyway. The shaft key curves slightly in order to provide interference fit in the hub key groove.

Clean the clutch plate and clutch rotor.

Align the shaft key with the shaft keyway.

Place the clutch plate and the hub assembly (1) onto the compressor shaft.

Remove the forcing tip on the J 33013 remover or equivalent.

Reverse the body direction on the center screw.

Install the J 33013 remover/installer tool or equivalent with the bearing.

Back off the body of the J 33013 remover/installer tool or equivalent as necessary in order to permit the center screw to be threaded onto the end of the compressor shaft.

Hold the center screw with a wrench.

Tighten the hex portion of the J 33013 remover/installer tool or equivalent in order to press the hub onto the shaft.

Tighten the body several turns.

Remove the installer. Ensure that the shaft key remains in place in the keyway.

Install the clutch plate and hub assembly to the final position. Ensure that the air gap between frictional surfaces of the clutch plate and clutch rotor measures within 0.50-0.76 mm (0.020-0.030 in).

Remove the J 33013 remover/installer tool or equivalent.

Verify proper positioning of the shaft key. Ensure that the shaft key is even with or slightly above the clutch hub.

Spin the pulley rotor by hand in order to verify that the rotor does not rub against the clutch drive plate.

To Remove:

 

Remove the clutch plate retaining bolt.

Remove the clutch plate assembly.

Remove the clutch hub/bearing snap ring.

Remove the clutch hub/bearing assembly.

Remove the clutch coil connector bracket screw.

Remove the clutch coli snap ring.

Remove the clutch coil assembly.

To Install:

 

Install the clutch coil to the compressor.

Install the clutch coil snap ring.

Install the clutch hub/bearing assembly.

Install the clutch hub/bearing snap ring.

Oil the thinnest air gap shim and install inside the clutch plate.

Install the clutch plate assembly.

CAUTION

Make sure that the drive plate does not drag against the pulley when the pulley is rotated.

 

Ensure that the air gap between the pulley and the drive plate measures within 0.35-0.65 mm (0.014-0.026 in).

Install the clutch plate retaining bolt

Torque bolt to 13 ft lb (18 Nm).

I know the procedure, but what I'm asking is the tool the same for this compressor (HU6) as the V5 style for removing the clutch?

My post shows the tool needed. As for if it's the same tool you may want to ask an A/C tech.
