Changing a clutch involves several key mechanical steps, primarily centered around removing the transmission to access the clutch assembly.
Here is a step-by-step guide to changing a clutch based on the provided process:
To change a clutch, you must typically gain access to the clutch assembly by removing the transmission or transaxle, replacing the components, and then reassembling the system.
Here is a breakdown of the process:
STEP 1: PARK CAR IN A SECURE POSITION.
- Before starting any work, ensure the vehicle is parked on a flat, level surface.
- Engage the parking brake firmly.
- Use wheel chocks on the wheels opposite the end being lifted to prevent any movement.
- Lift the vehicle safely using a jack and support it securely on jack stands. Never work under a vehicle supported only by a jack.
STEP 2: GET THE TRANSAXLE READY TO REMOVE.
- This step involves preparing the transmission (or transaxle in front-wheel drive vehicles) for removal.
- It typically includes disconnecting various components attached to the transaxle, such as shift linkages, electrical connectors, and potentially driveshafts.
- Drain the transmission fluid if necessary, depending on the vehicle's design.
STEP 3: UNBOLT THE ENGINE MOUNT.
- To allow the transaxle to be separated from the engine and lowered, one or more engine or transmission mounts usually need to be unbolted or loosened.
- Properly support the engine and transaxle with jacks or specialized support fixtures before removing mounts to prevent damage or instability.
STEP 4: REPLACE THE CLUTCH.
- Once the transaxle is successfully separated from the engine and moved out of the way (often lowered and removed from under the vehicle), the clutch assembly becomes accessible.
- This involves unbolting the pressure plate, removing the old clutch disc, and inspecting or replacing other components like the pilot bearing/bushing and throw-out bearing.
- Install the new clutch disc (using an alignment tool), pressure plate, and related components according to the manufacturer's specifications.
STEP 5: REATTACH THE TRANSAXLE.
- Carefully lift and maneuver the transaxle back into position, aligning it with the engine and the new clutch assembly.
- Bolt the transaxle securely back to the engine, ensuring correct torque specifications are used for all fasteners.
- Reconnect all components that were disconnected in Step 2, including shift linkages, electrical connectors, and driveshafts.
STEP 6: RELEASE THE CAR JACK.
- Once the transaxle is fully reinstalled and secured, and all other relevant components are reconnected, carefully lower the vehicle off the jack stands using the jack.
- Remove the jack stands and the jack.
- Remove the wheel chocks.
After completing these steps, you would typically refill the transmission fluid if it was drained, bleed the hydraulic clutch system if applicable, and perform necessary checks before test driving the vehicle.
