1. Air Still in the System: Even with multiple bleedings, air can stubbornly remain trapped in the system. Consider these possibilities:
* Bleeding Procedure: Ensure you're using the correct bleeding procedure for your specific Ford Ranger model. Improper technique can leave air bubbles. Look up a video or detailed instructions specific to your year and model. A pressure bleeder can significantly help remove stubborn air.
* Master Cylinder: The master cylinder itself might be faulty or have internal leaks, allowing air to enter the system. Inspect the master cylinder for leaks and consider replacing it if necessary.
2. Clutch Cable (if applicable): While you mention a hydraulic system, some older Ford Rangers used a cable-operated clutch. If yours is cable-operated, the cable might be adjusted incorrectly, frayed, or broken.
3. Clutch Disc Issues:
* Incorrect Installation: The clutch disc might have been installed incorrectly. The alignment of the clutch disc with the input shaft and pressure plate is critical. A misaligned clutch will not engage properly.
* Damaged Clutch Disc: The clutch disc itself might be defective or damaged during installation. Check for any visible damage.
* Pressure Plate Problems: The pressure plate might be warped, damaged, or not providing sufficient clamping force.
4. Throwout Bearing: A faulty throwout bearing can prevent the clutch from disengaging completely, leading to incomplete engagement.
5. Input Shaft: Rarely, but possible, there could be damage to the input shaft of the transmission. This would be a more serious issue requiring further investigation.
6. Hydraulic Line Leaks: Carefully inspect all hydraulic lines for leaks, even tiny ones can cause problems.
Troubleshooting Steps:
1. Re-bleed the system one more time: Use a pressure bleeder if possible. This is the most likely solution if air is still present.
2. Inspect the master cylinder for leaks: Look for fluid around the master cylinder.
3. Check the clutch cable (if applicable): Adjust or replace as needed.
4. Visually inspect the clutch components: If possible, visually check the clutch disc and pressure plate for damage. This may require removing the transmission.
5. Consider professional help: If you're not comfortable with these steps, take your vehicle to a qualified mechanic. They have the expertise and tools to diagnose the problem accurately.
Remember safety first! If you're unsure about any of these steps, it's best to seek professional help. Improperly working clutch systems can be dangerous.
