Accelerator linkage

[UK Muppet]

I have just finished making a new accelerator linkage for my S2, the original was a LHD version and as I have converted to RHD I had to make a new linkage and pedal. I have used ball joints for the pivots and adapted as much of the LHD bits as possible, but that wasn't much. I made new bell cranks copied from photos and the 3 rods are adjustable. The pedal is the top section of the LHD pedal with an extension for the lower half. The lever on the side of the casting seems to be the same except for which side the ball pin is on, so I only had to acquire a casting. The linkage operates quite smoothly and returns without any additional springs though I will add one.
Although the carb spindles rotate through 90 degrees when the pedal is pressed I get the feeling the amount of pedal stroke is not what it should be. (never had or tried one to compare so it's just a feeling)
There is a lot more movement/stroke in the pedal if the linkage is disconnected which makes me think I'm not getting the amount of pedal stroke I should, but as said the spindles rotate through 90 degrees fully opening the butterflies so I am a bit puzzled.
Could someone with a RHD S2 take some measurements for me as follows,
Distance under the lever on the side of the pedal casting to the flat of the bulkhead
length of the link from the same lever to the outer bellcrank, centre to centre
Distance the pedal moves from rest to full throttle.
Thanks in advance for any help.

Tony, will you please post a photo of your throttle pedal to help understand what you’ve created.
The distance from the centre of the pin on the lever to the bulkhead horizontal flat 65mm
Centre to centre of that to bellcrank is 110mm
As the proper throttle pedal hangs down not pivots from the floor is why I’ve asked for your photo.
However bottom of throttle pedal, fully up to fully down 80mm
Note all figures are approx but should give you a starting point and after all one car might have more or less movement than another.

Hope that helps

Many thanks Geoff, I had a quick measure and the vertical link (110mm) I made is shorter so will make another one. However by extending that link my pedal will move further towards the front of the footwell.
Pedal stroke is approx 75mm at present, so not far off.
I made my pedal to be hanging not floor mounted.
So the next questions are,
Does the accelerator sit level with the brake pedal at rest?
Has anyone got a photo of an S2 pedal? side profile.
I made mine straight as that seemed to work okay and the only images I could find are for Series 1 pedals which have a curve in them and they appear to be the only ones for sale from the usuals.
Another point, there is a slotted plate for adjusting the pedal position so if I extend the vertical link it will move the pedal position and make the plate redundant.
Thanks again.

Tony, the S2 pedal is part no C26514 which also fits the S1 4.2 and yes they are curved, look at SGN Barratt for that part no.
Will have to get into the garage to remember the relevant position to the brake, it all just feels right when driving and as pootling along the highways and bye ways of Britain hasn’t required to much toe and heel it hasn’t mattered

Hi Geoff,
Thanks again, on Robeys site I could only find it listed as C20223 and that is for S1 but after looking at C26514 I can see you are correct. As for the curve I didn't mean the pad at the bottom that your foot rests on but the drop down arm above it. It seems to me this is a straight edge on the front nearest to you and it is cranked to the right, The SNG version has a serious crank in it. The S1 pedal is shown a fair bit different in shape. I will stick with my straight pedal as it seems to work fine. I don't have any interior installed except for the dash so can't tell if the position is correct or not, that's why I asked about position.
Cheers, Tony
