Accelerator Pedal Hinge Spring

RonD2 · Post by **RonD2** » Fri Sep 14, 2018 1:09 pm

Original missing in action. Going to install my new gas pedal hinge spring (WO-650483, G503-7371454, ORD9 Page 88 ) and can't find a photo in any of the TM's that show how it's oriented. The spring isn't symmetrical, one side is longer than the other, and it has a "twist" in it for some unknown reason (I see no need for it anyway). Searched the forum with no joy. It's a repop spring - not NOS - so I have no clue if it's correct or not.

It seems to me the long side should rest against the back of the pedal and the short side rests on top of the 2 hinge bolts? But maybe the other way around?

Thought I'd ask, perhaps to improve 50-50 odds on the coin flip. Any advice appreciated!

Hi Ron!
Long side goes under the pedal, as you surmised.

Take care,

Thanks Brian! A little more snap to pedal return now.

This is exactly why I love this forum! My M38A1 passed through many hands (most of them uninterested in originality or ever consulting the manual), and as a result, so much is missing. I didn't even know this little thing existed! Good timing, as I was just repainting my pedals.

If you look it up in the ORD 9, Page 99 (SNL-758 Sept 1956) it is only used till serial number 76674, after that it was not used or they switched to a different type of spring....

FYI...

My truck is 71757, so that should be the spring for me!

Hi all,

I'm just getting around to installing the return spring. Quick question - what holds it in place? Tension only? Thanks!

Yes. The geometry of the installation makes it stay put.

Hmm, a part I never knew about. Mine didn't and doesn't have it, doesn't need it.

Hi Bretto. Yep, I was also thinking "over-engineered" when I came across it. Jeep drove pretty good without it.

But for $8 it didn't hurt much. Not like some things do in this hobby!

Regards,

Maybe it's there only to leave some spring-back in the pedal if that (somewhat) goofy rubber socket separates from the ball on the end of the pedal rod while bouncing down the road? Can't think of a better reason.

Anyway, it was Wes that hammered me to read the manuals.......

And he's not in the habit of using a 12-ounce ball-peen with rookies.......more like a BFH.
