Instead of repairing, you should replace the slave cylinder. Here's a general outline of the process. Remember that specific steps may vary slightly depending on your Ranger's transmission type (manual or automatic) and engine. Always consult a repair manual specific to your vehicle's year and model for detailed instructions and torque specifications.
1. Preparation:
* Gather tools: You'll need a socket set, wrenches (likely metric), a catch pan for fluid, brake fluid (DOT 3 or DOT 4, check your owner's manual), rags, possibly a pry bar or similar tool, and of course, a new slave cylinder.
* Safety first: Wear safety glasses. Brake fluid is corrosive.
* Vehicle preparation: Secure the vehicle with parking brake and chocks.
2. Fluid draining:
* Locate the slave cylinder. It's usually attached to the transmission bellhousing near the clutch fork.
* Carefully drain some brake fluid from the master cylinder reservoir using a syringe or turkey baster. This will prevent overflow when you disconnect the slave cylinder line.
3. Disconnect the slave cylinder:
* Disconnect the hydraulic line from the slave cylinder. This usually involves loosening a fitting. Have a rag ready to catch any spilled fluid. Be careful not to bend the line.
* Unbolt the slave cylinder from the transmission. This might require removing some other components depending on the accessibility. Your repair manual will help you identify these.
4. Install the new slave cylinder:
* Install the new slave cylinder in the reverse order of removal. Make sure it's seated correctly.
* Reconnect the hydraulic line.
* Bleed the clutch system. This is crucial to remove air bubbles from the line. Use a helper to operate the clutch pedal while you open and close the bleed valve on the slave cylinder (or possibly at the master cylinder, depending on the setup). Refer to your repair manual for the bleeding procedure. You'll need to continue bleeding until you get a firm clutch pedal.
5. Test and refill:
* Check for leaks around the slave cylinder and connections.
* Refill the master cylinder reservoir to the proper level.
* Test the clutch operation several times.
Important Considerations:
* Repair Manual: This is essential. Pictures and diagrams will make the process much easier and safer. A Haynes or Chilton manual is a good investment.
* Transmission Type: The location and access to the slave cylinder may differ slightly depending on whether you have a manual or automatic transmission.
* Clutch Master Cylinder: If you're having issues with the clutch, it's possible that the problem lies with the master cylinder, not just the slave. A failing master cylinder often leads to a failing slave cylinder eventually.
If you're not comfortable with automotive repair, it's best to take your Ranger to a qualified mechanic. Improper installation can lead to further damage or safety hazards.
