Here's a general outline of the process. Specific steps may vary slightly depending on the transmission type (manual or automatic – you only need a slave cylinder for a manual transmission) and any modifications to your truck. Always consult a repair manual specific to your year and model F-150 for detailed instructions and diagrams.
Tools You'll Likely Need:
* Repair manual: Absolutely essential!
* Socket set (metric): Various sizes, including deep sockets.
* Wrench set (metric): Various sizes.
* Torque wrench: Crucial for proper tightening.
* Bleeding kit: For bleeding the clutch system after installation.
* Catch pan: To collect brake fluid.
* New slave cylinder: Make sure to get the correct part for your truck.
* Gloves: To protect your hands from brake fluid.
* Jack and jack stands: To safely lift the truck.
* Wheel chocks: For safety.
* Possibly a clutch alignment tool: Depending on your transmission.
General Steps (Consult your repair manual for specific details):
1. Safety First: Engage the parking brake, chock the wheels, and raise the truck securely using a jack and jack stands.
2. Access the Slave Cylinder: This usually involves removing parts of the transmission bellhousing. You may need to remove the starter motor, some bolts on the bellhousing itself, and potentially other components depending on your truck's configuration. Your repair manual will guide you on this.
3. Disconnect the Slave Cylinder: Carefully disconnect the hydraulic line from the slave cylinder. Be prepared for some brake fluid to spill – use the catch pan. This usually involves loosening a retaining clip or nut.
4. Remove the Slave Cylinder: This often involves removing bolts that secure the slave cylinder to the transmission.
5. Install the New Slave Cylinder: Carefully install the new slave cylinder, ensuring it's properly seated and aligned. Pay close attention to the orientation of the hydraulic line connection. Some slave cylinders require a specific alignment tool to ensure proper installation.
6. Reconnect the Hydraulic Line: Reconnect the hydraulic line securely, tightening to the manufacturer's specified torque.
7. Reassemble: Reinstall all removed components, ensuring everything is properly tightened to the manufacturer's specifications using your torque wrench.
8. Bleed the Clutch System: This is critical to remove air bubbles from the hydraulic system. Use your bleeding kit and follow the instructions in your repair manual meticulously. This usually involves pumping the clutch pedal repeatedly while someone opens and closes the bleeder valve on the slave cylinder.
9. Lower the Truck: Carefully lower the truck from the jack stands.
10. Test the Clutch: Start the engine and test the clutch operation. It should engage and disengage smoothly. If not, there might be air in the system requiring more bleeding or another issue.
Important Notes:
* Brake fluid is corrosive: Wear gloves and protect your paintwork.
* Use the correct type of brake fluid: Refer to your owner's manual.
* Torque specifications are critical: Improper tightening can damage components.
* If you're unsure about any step, consult a professional mechanic. This repair can be quite involved, and incorrect installation can lead to expensive repairs.
Remember, this is a simplified overview. Always consult a repair manual specific to your 1999 Ford F-150 for detailed instructions and diagrams. Taking shortcuts can lead to serious problems.
