REMOVAL & INSTALLATION
See Figure 1
- Disconnect the negative battery cable.
- Detach the master cylinder assembly from the actuator cylinder by disconnecting the hydraulic line.
- Remove the transaxle assembly, as outlined earlier in this section.
- Remove the clutch actuator cylinder from the transaxle.
- Lubricate the inside diameter of the bearing with clutch bearing lubricant GM part no. 12345777 or equivalent.
- Install the actuator cylinder in the transaxle, then install the transaxle assembly.
- Connect the master cylinder-to-actuator hydraulic line.
- Bleed the hydraulic system, as outlined later in this section.
- If removed, install the air intake duct.
- Connect the negative battery cable.
HYDRAULIC SYSTEM BLEEDING
Do not use fluid which has been bled from a system to fill the reservoir as it may be aerated, have too much moisture content or possibly be contaminated. Clean the dirt and grease from the cap to ensure that no foreign substances enter the system. It is also important to maintain the fluid level in the clutch reservoir to the top step with hydraulic clutch fluid Hydraulic Clutch Fluid GM P/N 12345347 or equivalent.
- Attach a hose to the bleeder screw on the clutch actuator assembly and submerge the other end of the hose in a container of hydraulic clutch fluid.
- Depress the clutch pedal slowly and hold.
- Loosen the bleeder screw to purge air.
- Tighten the bleeder screw to 18 inch lbs. (2 Nm).
- Let up on the clutch pedal.
- Repeat Steps 2 through 5 until all air is purged from the system.
- Fill the reservoir to the top step with hydraulic clutch fluid.
- Repeat this bleeding procedure if there is a grinding noise during the clutch spin down procedure.
