How do you change the slave cylinder and where is it on a 86 Mazda B2000?

The slave cylinder on an 86 Mazda B2000 is located on the transmission, where the clutch line connects to it. It's a fairly involved job requiring some mechanical aptitude and tools. Here's a general overview; however, I strongly recommend consulting a repair manual specific to your year and model Mazda B2000. Repair manuals provide detailed instructions and diagrams vital for this job.

Tools You'll Likely Need:

* Socket Set: Various sizes, including those for the clutch line and possibly transmission bolts.

* Wrench Set: Open-ended and box-end wrenches may be needed.

* Clutch Alignment Tool: Crucial for proper reinstallation of the clutch.

* Bleeder Wrench: For bleeding the clutch system.

* New Slave Cylinder: Make sure you get the correct part for your specific vehicle.

* Jack and Jack Stands: Essential for safely working underneath the vehicle.

* Drain Pan: To catch any fluids.

* Gloves and Safety Glasses: Always important when working on a car.

* Torque Wrench: To tighten bolts to the manufacturer's specifications.

* Shop Towels or Rags: To clean up spills and keep things tidy.

General Steps (Consult your repair manual for precise steps and torque specs):

1. Safety First: Park the vehicle on a level surface, engage the parking brake, and chock the wheels. Disconnect the negative battery terminal. Raise the vehicle securely using a jack and jack stands.

2. Drain Transmission Fluid (Possibly): Depending on your access to the slave cylinder, you may need to drain some transmission fluid to give you more room to work.

3. Disconnect Clutch Line: Locate the clutch line connected to the slave cylinder. Use the appropriate wrench to carefully loosen and remove the fitting. Be prepared for some fluid to leak; have a drain pan ready.

4. Remove Slave Cylinder: The slave cylinder's mounting may vary slightly depending on your specific model. You may need to remove some bolts or clips securing it to the transmission. Observe how it's mounted carefully before removal to ensure you can reinstall it correctly.

5. Install New Slave Cylinder: Carefully install the new slave cylinder, ensuring it's seated properly. Tighten the mounting bolts to the manufacturer's specified torque.

6. Reconnect Clutch Line: Connect the clutch line to the new slave cylinder. Tighten it securely to prevent leaks.

7. Bleed the Clutch System: This is crucial to remove air bubbles from the clutch hydraulic system. Use a bleeder wrench on the bleeder valve (usually located on the slave cylinder or somewhere on the clutch line) and have someone pump the clutch pedal while you open and close the bleeder valve to release air. This process may need to be repeated several times until no more air bubbles are expelled. Refer to your repair manual for proper bleeding procedures.

8. Lower Vehicle and Test: Lower the vehicle carefully. Start the engine and test the clutch pedal. It should feel firm and operate smoothly. If the clutch pedal feels spongy or doesn't engage properly, you may need to bleed the system again or investigate other potential issues.

Important Considerations:

* Transmission Removal: In some cases, the transmission might need to be partially or fully removed to access the slave cylinder properly. This is a much more advanced procedure.

* Fluid Type: Use the correct transmission and brake fluid specified for your Mazda B2000.

* Clutch Alignment: If you have to remove the transmission, proper clutch alignment is critical to prevent damage.

Again, I cannot stress enough the importance of consulting a repair manual specific to your 1986 Mazda B2000. This information is for general guidance only and should not be considered a substitute for professional advice or a detailed repair manual. Improperly installing the slave cylinder can lead to clutch failure and potential damage to your transmission. If you're not comfortable performing this repair yourself, take your vehicle to a qualified mechanic.
