If you notice that the clutch on your 1968 Ford Mustang GT Fastback (Bullitt) is engaging too high, slipping, or feeling unusually stiff or loose, it could be an indication that the clutch needs adjustment. A misadjusted clutch can lead to poor vehicle performance and potential damage to the transmission over time. To restore proper clutch function and ensure smooth driving, you'll need to adjust the clutch. Here is how to solve this issue:
Step 1: Gather Necessary Tools
To adjust the clutch, you will need:
Step 2: Locate the Clutch Adjustment Mechanism
The clutch adjustment mechanism on a 1968 Ford Mustang is typically under the car, near the bell housing where the clutch fork is located. This part is usually found towards the rear of the engine bay, where the engine meets the transmission. The clutch fork is a lever that engages and disengages the clutch.
Step 3: Identify the Adjustment Nuts
Once you locate the clutch fork, look for the adjusting rod that extends from the clutch fork to the linkage. The adjustment nuts will be present on this rod. These nuts are often located close to where the rod connects with the clutch fork. Use the flashlight if visibility is poor.
Step 4: Loosen the Locknut
Before making any adjustments, you need to loosen the locknut on the adjusting rod. This locknut secures the adjustment nuts in place. Using the appropriate size wrench, turn the locknut counterclockwise until it is loose enough to move freely along the rod.
Step 5: Adjust the Clutch Free Play
With the locknut loose, you can now adjust the free play of the clutch. Turn the adjustment nut by hand or with a wrench. Turning the nut clockwise will decrease free play (moving the clutch fork closer to the pressure plate), while turning it counterclockwise will increase free play (moving the clutch fork away from the pressure plate). Aim for about 1 inch of free play at the clutch pedal, ensuring there's sufficient gap for proper operation without drag.
Step 6: Tighten the Locknut
Once you've adjusted the clutch to the desired free play, tighten the locknut back in place. Hold the adjustment nut steady with one wrench while using another to turn the locknut clockwise until it's secure. This ensures your adjustments stay in place.
Step 7: Test the Clutch Pedal
After making the adjustment, test the clutch pedal by pressing it several times. Check for smooth engagement and appropriate free play. If the clutch still feels off, you may need to readjust following the same steps until optimal performance is achieved.
Step 8: Double-Check Your Work
Finally, do a visual inspection to make sure everything is properly tightened and looks in place. Start the car and test drive it to ensure the clutch operates smoothly and that there are no unusual noises or issues.
By following these steps, you can adjust the clutch on your 1968 Ford Mustang GT Fastback (Bullitt) effectively, maintaining its classic performance and drivability.
