1. Preparation:
* Cleanliness is crucial: Thoroughly clean the fitting on the slave cylinder and the end of the clutch line. Use brake cleaner (or a similar solvent designed for automotive parts) and a clean rag. Any debris can prevent a proper seal.
* Inspect the fitting and line: Check both for damage. A damaged fitting or line will need to be replaced. Look for bends, cracks, or corrosion.
* Gather your tools: You'll need a suitable wrench (likely a flare nut wrench) that fits the fitting perfectly to avoid rounding it. A line wrench is ideal. Have some rags ready to catch any spilled fluid.
2. Installation:
* Lubrication: Apply a thin layer of brake fluid (or a high-quality silicone-based lubricant specifically designed for brake systems) to the threads of the fitting. This will help prevent galling (metal-on-metal seizing) and make the installation easier. Do not use grease or oil.
* Hand-tighten: Carefully start screwing the fitting into the clutch line by hand. This ensures you get the threads started straight.
* Wrench tightening: Once the fitting is started, use your wrench to tighten it. Do not overtighten. Tighten it firmly, but don't use excessive force. Overtightening can damage the fitting or the line. You should feel resistance but it shouldn't be a struggle. Consult a repair manual for the proper torque specification if possible, as over-tightening can damage the fitting or the line.
* Check for leaks: After tightening, carefully inspect the connection for any leaks. A small leak may appear as weeping brake fluid. If you see any leaks, loosen the fitting slightly, reapply lubricant, and retighten carefully. If it still leaks, you may have a damaged fitting or line and will need to replace them.
3. Bleeding the Clutch System:
After successfully reinstalling the fitting, you'll need to bleed the clutch system to remove any air that may have entered during the process. This is essential for proper clutch function. There are various methods for bleeding a clutch system (pressure bleeding, vacuum bleeding, gravity bleeding). Consult your repair manual for the correct procedure for your '87 Ford Ranger.
Important Considerations:
* Repair Manual: A repair manual specific to your '87 Ford Ranger is highly recommended. It will provide detailed instructions, torque specifications, and diagrams.
* Professional Help: If you're not comfortable working on your vehicle's braking system, it's best to take it to a qualified mechanic. Incorrectly installing or bleeding the clutch system can lead to clutch failure and safety hazards.
Remember, brake fluid is corrosive. Wear safety glasses and gloves when working with it. Properly dispose of used brake fluid according to local regulations.
