Accelerator linkage 'challenge'
I have my pedals floor mounted and the accellerator pedal pivots at the bottom. As a result I need to pass a clevis pin & pushrod through the
bulkhead, turn 90 degrees and convert the 'push' action to a 'pull' and connect it to my throttle cable which goes back up the
tunnel to the engine bay (middy).
Can anyone suggest a quick and easy way of doing this? I was thinking about a bell crank or quadrant which bolts on the bulkhead but I am hoping there
might be something a little more 'off the shelf' available somewhere.
Any ideas guys?

Possible to route a cable back into footwell and approach the pedal from the foot side with some sort of guard panel?

You would need to cut a slot in the bulkhead.

You will get a more reliable operation if you do it properly imho
You wont get the feeling by going through a bellcrank ect and its one more thing to go wrong.

Some really creative ideas there - thanks for all the input.
As suggested, I think the most sensible way would be to re-engineer the pedal and move the pivot point up and the clevis pin can then be attached
directly to the cable. The only problem there is achieving the correct amount of cable travel - I would have to move the pivot up quite a way to
achieve that. Is there any way of 'amplifying' pedal movement?

I see what you mean but my V6 Duratec needs about 2" of cable travel to get WOT. If you are using bike TB's then that might explain the
difference.
Mark, what is the length of your pedal from the pivot?
I'll make a cardboard mock-up before I get the welder out

That's great Mark - all I have to do is convert the drawing into metal now
Thanks for all your help

We did this as we found we couldn't easily get the required travel for the 40's attaching the cable below the pivot:
Seems to work very well. The bell crank has a pair of small bearings in it, it needs some rose joints as the plastic things are a bit flexy and work
at as nasty angle.
HTH,
Andy

Aha - something along the lines of my first thoughts.

Possibly think of a cut down grooved quadrant like the sierra clutch one. Nice linear pull, no extra friction and no levers. Adjust radius for
ratio.
