Throttle Cable Adjustment

[Lewis's Friend]

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...!

There should be a metal clip that holds the ball into the plastic cable end. in your photo it looks as though it is missing. I'll take a photo of mine when I finish my lunch.

That would be very kind, thanks.

Thanks very much Lewdon. I'll have to see if I can make one up - I suspect finding one in the wild would be tricky!

Edit - they seem to be on ebay for a fiver. You live and learn!

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.

Well, I've put mine back on the outer ball, which means I've been able to get rid of all the dead travel at the top of the pedal.

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

Thanks for the feedback. I've not checked at the pedal end of things, so I'll have a little look and see where I stand. Possibly more excellent fabrication work (bodgery) needed from me...!

Again, thanks for all the pictures and advise. I'll have a look at the pedal setup and put a stop in (of it hasn't already been done - it was a PHer's so maybe already been done).

Another little project! Still, this is why I bought it. Half to drive and half to tinker... Although I think I'm about to get a Trabant on my drive soon which was going to be my summer time-waster!

I recently adjusted my cable as the pedal was constantly getting stuck on the carpet, it's also pretty close to the end of travel on the adjuster. Are you saying you now have a little more to play with since moving to the original fitting point?

The outer pivot is further away (not by much admittedly!) from the cable adjuster than the original position. Because you're pulling the cable a bit tighter, you're effectively giving yourself a bit more adjustment.
