However, if you're determined to do it yourself, here's a general overview. Remember to consult a repair manual specific to your 1991 Ford Ranger model (engine size matters!) for detailed instructions, torque specifications, and diagrams. These steps are a *general guide* and may vary slightly depending on your specific truck.
1. Preparation:
* Safety First: Disconnect the negative battery terminal. Use jack stands securely under the frame, *never* rely solely on a jack.
* Gather Tools: You'll need a comprehensive set of tools including various sockets, wrenches (metric), a clutch alignment tool, a transmission jack (highly recommended), a torque wrench, a drain pan, and possibly a pry bar.
* Parts: Obtain a new clutch kit (clutch disc, pressure plate, throw-out bearing, pilot bearing – sometimes included in the kit, sometimes sold separately). Ensure they're the correct parts for your specific engine and transmission.
* Repair Manual: A Haynes or Chilton manual for your specific year and model is crucial.
2. Removal:
* Drain Transmission Fluid: Completely drain the transmission fluid into a drain pan.
* Disconnect Components: Disconnect the driveshaft, clutch cable, shifter linkage, and any other components connected to the transmission.
* Remove Starter: Access and remove the starter motor.
* Support Transmission: Securely support the transmission using a transmission jack.
* Remove Transmission: Unbolt the transmission from the engine bellhousing. This usually involves several bolts. This is the most physically demanding part of the job. Slowly and carefully lower the transmission using the jack.
* Remove Clutch Components: Once the transmission is removed, you can access the clutch disc, pressure plate, and throw-out bearing. Remove them carefully, noting their orientation.
* Replace Pilot Bearing (if necessary): This bearing is located in the end of the crankshaft. It might require a special tool for removal and installation.
3. Installation:
* Install Pilot Bearing (if necessary): Install the new pilot bearing.
* Install Clutch Disc: Install the new clutch disc, ensuring it's properly seated.
* Install Pressure Plate: Carefully install the new pressure plate, ensuring it's properly aligned.
* Install Throw-out Bearing: Install the new throw-out bearing.
* Install Transmission: Carefully align the transmission with the engine and bellhousing, using the transmission jack for support. Slowly bolt it back in place.
* Reconnect Components: Reconnect all the components you disconnected earlier (driveshaft, clutch cable, shifter linkage, etc.).
* Refill Transmission Fluid: Fill the transmission with the correct type and amount of transmission fluid.
4. Final Steps:
* Check Clutch Operation: Start the engine and carefully test the clutch pedal. It should engage and disengage smoothly.
* Check for Leaks: Inspect for any fluid leaks around the transmission and bellhousing.
* Test Drive: Test drive the vehicle to ensure the clutch is functioning properly.
Important Considerations:
* Torque Specifications: Always use the correct torque specifications from your repair manual. Over-tightening can damage threads or components.
* Alignment Tool: Use a clutch alignment tool to properly align the clutch disc during installation. Improper alignment can lead to clutch slippage or damage.
* Professional Assistance: If you encounter any difficulties or are unsure about any step, it's best to seek professional assistance from a qualified mechanic.
This is a simplified overview. The actual process can be far more complex and time-consuming. Again, refer to a repair manual specific to your 1991 Ford Ranger for detailed instructions and diagrams. Attempting this repair without the proper knowledge and tools can result in damage to your vehicle and potentially serious injury.
