How to adjust the clutch on a 1969 AMC AMX?

When driving a classic car like the 1969 AMC AMX, a frequently encountered issue is clutch slippage or difficulty in engaging gears. This problem typically arises due to improper clutch adjustment. Symptoms may include a clutch pedal that feels too loose or too tight, grinding gears, or a car that shudders when shifting. If you are experiencing any of these issues, it is most likely due to clutch misalignment. Fortunately, adjusting the clutch on a 1969 AMC AMX is a relatively straightforward process. Here is how to solve this issue:

Step 1: Locate the Clutch Adjusting Mechanism
First, park your AMC AMX on a level surface and ensure that the engine is off. Open the hood and locate the clutch adjusting mechanism. It is typically found on the driver’s side of the engine bay, near the firewall. The clutch linkage is a mechanical rod or cable connecting the clutch pedal to the clutch arm.

Step 2: Identify the Clutch Rod and Lock Nut
You will find a rod that connects the clutch pedal to the clutch fork, along with a lock nut that secures its position. The lock nut generally looks like a regular hex nut and is situated along the threaded part of the rod. Ensure that the lock nut is clean and free of dirt or grease for easier handling.

Step 3: Loosen the Lock Nut
Using an adjustable wrench or a suitable sized spanner, loosen the lock nut by rotating it counterclockwise. This allows you to make adjustments to the clutch rod without interference. Make sure to loosen it enough to freely turn the rod, but be careful to not remove it entirely.

Step 4: Adjust the Clutch Rod
Turn the clutch rod to adjust the clutch pedal’s free play. If the pedal feels too loose, you need to turn the rod clockwise to shorten it, increasing the tension. Conversely, if the pedal feels too tight, turn the rod counterclockwise to lengthen it, reducing the tension. A well-adjusted clutch should have a free play of about 1 to 2 inches when you press the pedal with your hand.

Step 5: Retighten the Lock Nut
Once you have the desired tension, hold the clutch rod in place and retighten the lock nut by turning it clockwise with your wrench. Make sure it is firmly tightened to prevent any unwanted movement of the rod during operation.

Step 6: Test the Clutch Pedal
Finally, get into the driver’s seat and press the clutch pedal a few times to check for proper engagement and disengagement. Start the car and go through the gears to ensure that the clutch operates smoothly without slipping or grinding.

By following these steps, you will have a properly adjusted clutch on your 1969 AMC AMX, resulting in smoother gear shifts and better overall performance. Regular inspection and adjustments will help maintain the longevity and responsiveness of your clutch system.
