Gas Pedal Stem Seal

[bkahler]

I purchased and installed a Gas Pedal Stem Seal from DCM Classics.  I believe this seal is one of the reasons my gas pedal is sticking after being pushed down.  Prior to installing the gas pedal stem and seal the rod stem easily slides through the rubber/aluminum bushing but once installed the angle of the stem as it passes through the seal is not very good.  This causes binding and rubbing loud enough to hear (when the engine isn't running that is).

 

 

Based on the size of the floorboard opening there needs to be something there but I'm not convinced this seal is the answer. 

 

Am I missing something?

No seal was used on the gas pedal stem.

Interesting but not surprising.

 

So there was just a 1-1/2" hole in the floorboard for the pedal stem to pass through?

That's all I have ever seen.

Thr pedal rod moves in a slught arc.

You might be able to use a bellows type seal if you feel you want a seal.

I think in this case I'll start with minimal interference which would be just a big hole.  Later if it bugs me enough I'll pop a hole in a rubber sheet and fasten it to the floorboard.  

 

Thanks for the feedback.

Heresy, I know but Chevy trucks of the kick starter era used a bellows seal that would probably adapt.

I remember the cheviee 216,235 waffle pattern stomp starters with the bellows floor seal...Dodge was cheap in that department.

Guess they felt they didn't need a floor board to starter pedal seal.

Last night I browsed several Chevy parts sites and couldn't find any reference to gas pedal floorboard seals.  I was actually quite surprised to find parts coverage wasn't much if any better than what we have available for our Pilothouse trucks.  It's quite possible I just didn't know what to look for.

Google first search....maybe trim it down or use a more universal bellows seal..

Thanks for the links.  I'm going to contact one of those vendors and ask for dimensions.  If they are close, I might just order one to see how well it will fit.

I guess my question is why?

I have no real definitive answer to that question

 

By design it looks like something should have been there.  Dodge apparently have used pedal seals in some of their vehicles and the fact that vendors actually sell a piece that is shaped to fit the opening seems to indicate it should have been there.  I'm wondering if Dodge originally intentions of installing a seal but possibly changed their mind due to cost.

The floor mat was the original loose seal.

It was just a work truck.

I don't know anything about the trucks, so this may just be non-sense, but wouldn't a seal like that mount similar to the clutch and brake pedal seals? At least as used on cars. That is it does not actually secure through the floorboard. Instead it goes on the rod but on the exterior of the floorboard. So it essentially seals against the floorboard from the exterior and only when the pedal is in its home position. Step on the pedal and the seal travels with the rod. Just a thought.

My two cents is that there was probably one designed but omitted for production cuz it caused a sticky throttle in pre-production units...between the firewall pad and the floormat, the throttle linkage opening was covered up enough that Dodge Truck engineers said "close enough...ship it" ?

Yeah, the evidence seems to fit that hypothesis
