MG MGA - Accelerator Pedal Travel

I’m wondering if anyone else has this problem. When I drive the car for long distances, my right foot/ankle is very uncomfortable. The accelerator pedal is higher than the brake and clutch pedals and keeps the foot at a very difficult angle. There is plenty of travel in the accelerator pedal, so my plan was to just adjust the pedal linkage to bring the pedal lower. This seems to be a comfortable answer except for one thing. There is no pedal stop for upward travel of the pedal. When I take my food off the accelerator pedal it springs back up higher than the brake and there is about 2 inches of travel before any effect on the carbs. I’m sure is can come up with a method for a stop but, before I do, has anyone else attacked this situation and come up with a clever way to implement a stop?

Frank, there should be a top and bottom stop on the accelerator pedal. The top stop is the lower of the two bolts on the pedal box, the bottom stop is the bracket on the floor. The floor bracket has an elongated hole so that the stop bolt position can be adjusted to 'full open' on the carbs so the cable isn't strained.

Lindsay -- I should have made my self clear. This is a LH Drive car. At the accelerator, there is just a pivot. There is a stop on the floor for downward pedal travel limit, but no stop for upward pedal travel. The pedal, at rest, is pulled up by the throttle return springs.

Frank- I am away from my car for the winter so I cannot look but I do seem to recall that on one of the pivots for the gas pedal and I am leaning that it's the one by your foot,has a screw that acts as a stop. It goes thru piece of rubber much like a piece of hose. It's not on the Moss site,but the top of the pedal goes past the cross bar,the one that goes across the firewall to the right hand side of the car,I think it's supposed to be up there.

Best photo I could find Frank. Not much info out there on the 'net and all my books are at home. Where that blue arrow is pointing to is what stops the pedal from traveling back too far. Don't remember if it's adjustable but maybe yours is missing completely ?

Sorry Frank, I just imagined it would be the same set up, but on the other side!

The Accelerator pedal--- My Coupe' is a converted ex-Californian, model, to RHD.
64 years ago--I had knee surgery for a torn cartlidge.
It had not worried me for years---but now that I run an MG A Coupe--
The accelerator pedal angle worries my knee. Its quite painfull.
The level of the pedal is correct-- Its slightly lower than the brake pedal.
Fords used to have a footrest at the side of the accelerator pedal.
The steps were arranged for 30 mph on the high level and 60 for the lower step.
Just roll the foot onto the accelerator pedal, while relaxing on the required step.
Now, my Coupe has one of these---it helps a lot, especially on day long drives.
Also, a 5inch cube of thick spongue plastic--suspended by a shoe lace, from the dash lamp S/W -- supports the side of my right knee against the door.
These tricks have made driving more comfortable and less painfull.
These thoughts may assist someone else.

This topic is covered on Barney's site; seems there is just a little bit that can be done:

It appears anyone who tries to access Barney's site thru the hyperlink may have an issue getting there. If the link does not work just go mgaguru.com and you can then go in and find the reference to the accelerator pedal topics.

It is an incorrect link. Delete the "s" for correct link, like this: -http://mgaguru.com/mgtech/carbs/cb114.htm

CRAP !!!!
Now the software will not allow me to edit my own post, because I didn't get it done within 5-minutes. The link I posted above was automatically changed to be incorrect (and still is).

Some web browsers have a defect in the software that will add that "s" even when it was not originally input. I think the MGE server is doing the same thing. I am pretty well convinced that many software engineers are commonly a brick short of a full load.

I just posted the correct link to this BBS, and it repeatedly comes back with the "s" added. Not my doing, and I have no idea how to prevent it. Please copy and paste the URL, but delete the "s" to make it work.

Barney, They come from a different planet -"see how good am I"!

I.W. Cowen. Can we have a photo of your 'stepped' footrest -- I want to see how and where it fits.

Thanks, Barry

Good day Barry,
If you would care to come back to me on the E-Mail, I'll be in touch.
Cheers -- Ian Cowen.

This is the link without the “s” - copy and pasted the link when the page was open.

Frank,
There is a screw in the accelerator pedal bracket that the top of the pedal arm rests on. There is a rubber sleeve that goes over the screw that cushions the pedal when you remove your foot from the pedal. If you do not have the rubber sleeve on the screw, it would allow your pedal to travel so it sits higher than the brake and clutch pedals. Check to see if you are missing the rubber sleeve or maybe the screw and rubber sleeve are missing altogether.

See the attached picture.

Here’s a picture of the assembly installed in my Coupe.

Jim -- This is what I was thinking about doing. My bracket does not have this screw & rubber bumper, and if memory serves (it often doesn't), there is no hole for a screw. I'll check when I go over to the shop today. Thanks for the pictures. I'm also not sure my bracket is deep enough for the screw.

Frank,
There should be a hole in your bracket. I took my pedal stop off of my car to take pictures and measurements. There are 6 pieces in the stop assembly.

There is one screw 1/4"-28 x 1-3/8" posidrive panhead screw. (1-1/2" will work)
One flat washer
One distance piece that is 3/4" long with a rubber sleeve that fits over the distance piece.
All of these are assembled on the right side of the bracket with the screw going through the hole in the bracket.
On the left side of the bracket, put the lock washer and the 1/4"-28 nut.

If your bracket does not have the hole, let me know and I will measure where it goes for you.

Here's another picture of the pieces partially assembled in their correct order.

Look on page A20 at illustration numbers 21-26 here.

These are what you need. They are shown for the RHD assembly but not shown with the LHD bracket for some reason. However, notice that there is a hole shown in the LHD bracket.

If you have the rubber sleeve upper stop in place, and you still want the accelerator pedal to rest a little lower, you might try adding a piece of heater hose to increase diameter of the rubber stop tube. I haven't measured diameter of the original rubber stop, but I suspect it may be 5/8", meaning you would need 5/8" heater hose to cover it.

If you do this, then with the pedal resting a little lower you would need to readjust the throttle cable length and the lower pedal stop.

Yes, it’s all clear now. I examined my accelerator pedal and the hole was there. In a moment of clarity I remembered seeing that part in my frame-up restoration 2 years ago. Looking in some boxes I found a plastic baggie with the entire assembly (less the rubber). Included was a note “Accelerator pedal stop. Duplicate????” Since neither the Moss nor the B&G catalogs show this part in their drawings (The Moss drawing doesn’t even show the hole), I assumed that, somehow, I had two floor stops. Shame on me for not being familiar with Barney’s “books” section.
Thanks to everyone for their information and patience.
