Equalizer Bar & Clutch Linkage Restoration

While not originally part of the plan, I recently incorporated the restoration of the clutch linkage.

My decision to restore these parts started when I removed the upper clutch rod. The ends of the rod have plastic bushings but they were completely worn away. The ends of the rod were worn out of shape. Additionally, the bar was from a '65 or '66 and the improper shape resulted in damage to the firewall were it emerges from the passenger area. The firewall was repaired with a hammer and dolly and I purchased the proper clutch rod from NPD.

This rod connects to the pedal and then to what is called the equalizer or z-bar. This bar pivots along a center point which is mounted on one side to the engine block and to the driver side frame rail on the other. When the clutch pedal is pressed, the top part of the bar moves toward the front of the vehicle while the pivot action causes the lower portion to move towards the back of the car. The points were the clutch rod mounts to this piece is worn and needs to be repaired since a replacement is $70.

The final part is another bar which connects to the lower part of the equalizer bar and to the transmission. When the pedal is pushed, this rod moves backwards and disengages the clutch. The mounting point on this piece was worn completely in half. As a result, I needed to purchase replacement from NPD.

I've restored or purchased new parts to complete all parts of the system except the equalizer bar. The bushings for the bar were all worn completely out. Each joint was metal on metal which wore away at the bar. I'll need to have the holes completely welded up and drill new ones. Once that work is done, I'll post a picture of the completely parts.
