Clutch control spring

Clutch control spring, item   04            23131241849          spring - 09/1980 and above.

The image makes this spring look like it goes on the outside of the rod, however, there is no spring return of the rod this way.  Should the spring be installed on the inside of the rod, between the rod flange and the clutch housing?

Thanks Again, Bill

Bill,

The spring goes over part number 4, I think the noun is a piston.

When you take this apart, you need to loosen up the clamp that holds the rubber boot to the transmission, before doing anything else, after the pivot bolt #11 is removed the spring will expand, and usually tear the rubber boot.

 Been there done that !!

If by chance I've confused you the spring goes between the piston , and the rubber boot.

That spring does go inside the rubber "boot" as shown and there might be a metal washer on one end - I cannot recall from when I last had mine apart.  It does go on the outside of the the piston (part#2) - it is primarily for moving the actuating arm back into position.

The metal washer is bonded to the underside of the rubber boot.

Thanks Bob & nhmaf.  Luckily I did not tear the boot on removal, however, I did order a replacement due to some age cracks.  I figured I'd get it while it was still available.  All the other rubber is in great shape, save this piece.  

I've got it finger tightened assembled with the spring on the outside of the piston as that seemed the way it should be, however, I still don't see how the lever arm can actually put pressure on the rod (i.e. nothing moves when I push with my fingers).  Perhaps the forces involved are greater than I can muster with my fingers and everything will be peachy once I assemble the lever to the cable and give it a pull with the clutch hand lever.

The degree of push rod movement is adjusted by the bolt that goes in through the end of the actuating lever and pushes against the outer end of the piston (through the center of the rubber boot).    This pushes the rod inward, and the tip of the rod pushes against the center of the diaphragm spring (large metal finger spring) in the clutch carrier assembly. It takes a bit of force to deflect that big spring (because its pressure keeps the clutch disk, friction and pressure plate pressed together when running down the road).

To put it simply - the spring pushes the arm (7) back. Nothing actually pushes the rod back - it will float with no pressure from the arm pressing it into the transmission.
Don't be surprised that you cannot move the rod inward with finger pressure alone, it should feel solid - the leverage of the hand lever and the arm multiplies the force. the actual movement from fully engaged to disengaged would only be a few mm.
