914World.com _ 914World Garage _ Throttle Pedal Issue

Posted by: Conrad192 Jul 25 2022, 10:15 AM

Pressing the gas pedal 1/4 way down, it has a "crunch" feel, and requires a lot more pressure. Pushing further it sudden becomes softer and the pedal suddenly goes way down. The lack of "fine control" is quite frustrating.

I found two issues. The PO had "fixed" the worn out pedal by bolting in a piece of hinge from the local hardware. That's sort of ok, except that he installed the pedal at 90 degrees from the floor. This placed the connecting rod to the bell crank at a excessive angle, creating an excessive side load on the bell crank arm. Ultimately cracked the arm's spot weld. That allowed the lever to be pushed even further to the right creating the binding.

A new pedal from AA and a little welding cured that issue.

As I was reinstalling the pedal cluster, I noticed that the clutch lever was worn almost completely thru. so I ground a nut to the size of the worn hold, pressed it in and then tack welded it place. Apparently due to my limited mental facilities, I didn't think to drill the nut BEFORE welding it and turning it into case hardened steel.
