Throttle Cable Adjustment
Discussion
Hi all
Quick question. I have been trying to adjust some of the dead travel at the top of my accelerator. My issue is, to have it set where I want it, the adjuster only has a few threads engaged which doesn't seem right.
However, I noticed for the first time that the cable is attached on a screw in the middle of the actuator arm, not on the ball at the end.
Is this normal does anyone know? A TVR special, or is this an after market special!?

Thanks, I've put it back to the normal position, which gives me more scope for adjustment. Much better...!
However, the plastic end that sits on the ball seems pretty loose. I'm not sure whether this has been damaged by having a bolt rammed through it or was a bit sloppy and was therefore modified.
If need be, can throttle cables be got hold of? I seem to recall that these are one of those things that you must hope you never need...!

My throttle cable (S3c) is identical to yours in that it has the same mid-arm screw attachment, so maybe another TVR inconsistency.The plastic adjuster snapped on mine last weekend, so I'm currently looking at replacement cable options.

In conjunction with the straight cut throttle plate I've fitted, I think I prefer this setup. It's increased the pedal travel, but I think this is an improvement as it allows a little more finesse on the accelerator. I'll se how I get on with it over a few more miles though.

and don't forget to fit some sort of pedal stop rather than the one on the throttle plate as all that does is to transfer the forces to the ends of the cable and that leads to it breaking.
Sorry, not sure I follow. What kind of stop is needed? I thought that at rest, the cable would just be under a small amount of tension. Can this cause damage?I'm not sure I understand where the failure can occur?
Thanks
I made a throttle stop out of some tube and a couple of 'top hat' end fittings designed for towel rail installations. Definitely worth doing to avoid overloading the cable at full throttle. However, the problem I mentioned previously occurs when you have the throttle completely closed (i.e. in the idle position) - you can adjust the throttle pedal position using the cable adjustment at the engine end, and if you adjust the pedal up too high the cable inner has to kink at the pedal end, which will lead to failure.

I think I did the prototype for Alan - used 1/2" studding with nuts and large washers. Difficult bit = push peddle to max and mark the baulkhead where to drill. Drill suitable hole and with a friend holding the peddle fully down, feed the studding through 'til it touches the back of the peddle. Fit washer and run nut up to the where the studding goes through the body. Get your friend to do the same from the inside and nip the nuts up. Check the throw of the peddle and that it hits the end of the studding just as the throttle is fully open or a mm or 2 before. tighten the nuts and cut the excess studding off from the outside so the tyre does not foul on it.
