I get asked the question on how to install this clutch gorilla spring so often that we made this Jpg. to help others. I thought I would share it here.


This is how we install this spring.. There may be other methods, but this one has proven time and time again to be the best method for us. Using the cross shaft as a fulcrum makes this task simple and easy.

Thanks for posting, easiest method so far.

My pleasure. It takes us about 5 minutes to get this on...

I know this has been done to death but I can't find anything on the adjustable bracket (F). It can move front to rear by about one inch. What is the reason and what is the correct position?

When in doubt ------ read the manual.

Frankie,

I must be missing it. The bracket that is bolted on with two bolts is slotted. It's the one that the spring is attached to. What is reason for adjustment?

The 2 extremes of the overcenter adjustment are:

1. It can increase the foot pressure required to push the pedal down (higher than normal).

2. Or it can be too light, in which case the pedal may stick to the floor.

Precisely, the point of the gorilla spring (and its adjustment) is to smooth the "force over distance" curve involved with engaging/dis-engaging the clutch with your foot - it's that simple.

Necessary equipment,

Electric chain fall or manual type...a engine hoist may work too
Old fan belt at least 50 inches long or thereabouts......

Procedure,

cover fender to prevent paint damage
position spring on linkage and hook the spring with the belt to the hoist..Actually the Vette to my amazement the fender started to rise too... showing how strong that damn spring really is
take up slack with the chain fall and hook the link over the bracket....

And your DONE.....

No unbolting anything or rolling around the floor,..... just stretching the spring to fit....

Or two minutes with a crescent wrench and a little patience. The procedure is in the ST-12 and been posted about many times. Its even simpler than the Wilcox method. You put a crescent wrench on the bellcrank extension (red lines in picture) and rock the whole ***'y forward and you'll find a 'sweet spot' where the spring practically falls on....
I've done it a dozen times.
