Thread: How to seal up the floor with through floor pedals?

Tweet

What is the best way to do this? I have a small space around the clutch and brake pedals and I'm trying to decide on the best way to seal it up. I was thinking about glueing down a piece of inner tube then spraying the rubberized under coating I have been using then laying the insulation on top of that. I'm just not sure how tight I can seal up the pedal...if I were to use a thicker piece of rubber like a grommet it might restrict the movement of the pedal so I'm not sure how to find that middle ground??

I'm on a mission to seal up the car. I have used seam sealer along the firewall and floor, but for around the pedals I am a bit stumped. Pictures would be great! Thanks

find a rubber seal that you can put around them pedals and mount it to the floor.

I think your idea is a good one. It should give you a reasonably good seal and still allow your pedal to move freely.

Thanks guys. I just don't want any gaps. I'll probably start by just cutting slits in the inner tube to slide the pedal arms through instead of actually cutting out holes. I'm still a little skeptical of the seal, but I can't see finding a pre made moulded seal to fit perfectly in a square hole!

I probably won't get back on this for a week or two so if anyone has any great ideas let me know!

That does seem like a fancy version of what I would try to do. 24 bucks isn't bad, but I would need two so I'll probably pass on those, but at least I feel more comfortable knowing I'm on the right track. It just seems like having the square pedal arm rubbing on the rubber so much it will tear unless it is installed with a small gap then what's the point?

Make a disc that clamps to the pedal, so it comes up under the seal and just touches it with the pedal right up. Most driving, the pedals are all the way up, anyway. Not going to get much fumes in the cab in the short time a pedal is down.

Interesting idea though I'd have to look at how that would interfere with the clutch safety switch also mounted to that pedal arm. The brake switch is hydrualic so it wouldn't be an issue on that one. I wasn't even thinking about fumes as much as water, but I suppose any fumes might be as much or more of a concern.

Hey Robert, I understand your desire to seal it up as tight as possible and I'll need to do something similar for mine eventually, but I think the holes are positioned in such a place that unless you drive the car into a river, you're not going to get much water in there. Even in a torrential rainstorm I think the chassis and various other things would keep water from directly splashing up there. Besides, how often are you going to drive it in the rain after you put all that work into it?

Your idea should work pretty well for blocking out heat, exhaust fumes & splashing. I also like the link Roger posted but not sure if I'd want the chrome to draw attention to it. Maybe black or carpet colored would be a little less conspicuous.
BillyZZ's idea sounds good, too, if it will clear your safety switch. Isn't it great to have options?! Keep us posted on what you come up with.

Randy

I used the seal that Roger linked to. After I put it in, I didn't like the "flash", so I painted it flat black. Then I didn't like that so I removed the paint and brushed the aluminum to flatten the shine.

you're probably right Randy, but I've over thought everything on the car so far so why stop now?! If I just went ahead and got stuff done I wouldn't have anything to do . I won't ever set out in the rain in the car (I sure did spend enough time adapting that wiper system to work though..), but I do hope to not be afraid to just drive it so I'm going out of my way to avoid rust (helping myself out in 20-40 years). I'm sure the rubber undercoating and super sticky insulation will handle a drop or two though if it happens.

Don't know how much movement in your pedals but you could try mounting a shifter boot under the floorboard and have the hole where the shifter go's around the pedal shaft. Basically a reverse shifter boot. Have it in the collapsed state when the clutch is up and in the extended state when the clutch is depressed.

Just a thought.

Thanks for the links Bob. The round ones won't work. The second one being felt that you staple to the original wood floor board makes me realize that whatever I choose to do it'll be fine. I don't have wood to staple to, but I think Gorilla glue will be a fine substitute
