So my clutch cable needed adjusting, appears the nut has backed off. I want to double nut it, but can't find the right size. Somewhere between 6mm an 8mm? Anyone know?

yes need another nut to locked it. I’m sure Ace hardware have them and maybe just bring what you have now.

Somewhere between 6mm and 8mm would be ...
:drum roll:
M7

Takes an 11mm wrench.

Using an 11 mm wrench. Uncommon sizes: I now bring spares.

That nut is the only reason I now own a long 11 mm socket and a ground down 11 mm open ended wrench.

I have a set of thin metric bicycle wrenches I use. That looks fine threads, so 1.0 thread pitch.

Yeah, after rummaging through my stash of misc nuts and bolts, and can't find, I guess I'll remove it and ... Off to the hardware store I go!

Rainy day so can't take it topless anyway...

Thanks for the replies, I'll provide the correct answer after I get it.

Starting w best guess of 7mm X 1.0

I've bought M7 nuts at a True Value in years past.

I am pretty sure M7 x 1.0. And you need a pair of 11mm wrenches, including a thin open end wrench.

I always use a baby vice grip around the cable shank that way it doesn’t fall off while you operate the clutch for adjustment. And yes, I always double nut at the Transmission side of the cable. My buddies Scott Sandford and Randy Beck said for the cable end inside the cab use the 11 mm wrench opening as the length to set the nut for the clevis fork at the pedal assembly. That way you’ll have enough cable length at the Transmission side to double nut.

This thread raises a question I've had for a while. I'm working through my 914 replacing lots of wear parts including the clutch and accelerator cables. If the clutch fork is clearly made for a trunnion like this (which mine still has)


why are 90% of the available replacements this?



Having seen some clutch forks with the square peg, OK literally triangular peg, in a round hole and the ensuing wear it causes on the fork I figure there must be a good reason for the switch but I'm not getting it.

Lots of people here say to use this one. I have not yet but there have been many other discussions on this issue. It needs to be trimmed to fit.

thats a crazy price...
the solid metal 356 style is only like 12$ or something.

Agreed. The plastic one is only $8 but I would not use it. These are getting harder to find for some reason.

How very Porsche. Why use a $3 part when a $45 part is available? Hard to imagine that a suitable proper fitting "barrel" type clevis couldn't be found/manufactured for less than a fiver each and sold for $10.

I'm thinking of $45 reasons!

In fact a nut that fits loosely over the threads will work in a pinch.
