Middle Year Smog Pump Plumbing?

[1yearonLy]

Anyone have a diagram or some pics of how the smog pump mounts and where the plumbing goes? All I have to go on is:



Mine is a '77 so I have no cat converter.

Thanks.

scott, love your car.

do you still have all the plumbing underneath your car? that big rubber hose in your photo hooks to a manifold of sorts that gives each cylinder a breath of fresh air at the exhaust. i hope it is just plugged at the engine tin (back of car, drivers side, just left of the crank pulley). if not, you are missing some stuff.

Has this car passed CA emmisions before? Not sure how a '77 will pass without a cat. Heck, if you can get by without a cat, you can probably get by without the pump too.

Here is a picture of the "Y" bracket on the left side of the motor adjacent to the distributor. The slotted brace to adjust the belt connects to the outer coil fastener. The white cap is where the hose connects. There is plumping to each exhaust port via air injectors beneath the engine. So there is much more hardware involved than you have pictured.

Thanks.

The '77s did not have cats when they were new. I have the air tubes and the underside stuff in other boxes. That all looks pretty straighforward.

I might be able to pull this off!! (if needed). I'm trying every avenue before that if it'll work.

That little white cap beneath it is where the hose goes to?

Yes.

That cap is merely the top off a brake fluid bottle to keep dirt/water out of the port. It snaps on nicely.

How about the doohicky at the bottom of this pic? I know what the big sixtopus thing and the air injectors are but I can't figure out this thing:



Does it relate to the thing on the far right of this pic:

there is a filter housing missing too. it sits up top and filters the air prior to be drawn into the pump.

ugh..adding the smog pump..my sympathies..i know you've gotta be hating that. of course once it passes emission, i know you'd NEVER consider subsequent removal......

EGR tube, and yes it goes with the other dohicky.

The first and best course of action will be to smog it down here... Failing that I have plan B:

...having my brother register it in Alaska (he lives there) and then send me the plates. It'll work just fine until I get pulled over. Then it's just a fix-it ticket. I could last weeks or years with that, it's luck of the draw.

**One caveat to all this. When a car turns 35 under the new CA smog laws, it is no longer subject to the visual component of the test, just the tailpipe test. I only need to get-by for 7 more years.

Anybody have a pic as to how this pump bar attaches to the fan housing?? Here's what I have and I don't see how or where it bolts on..



Also missing are the spacers for that through-bolt that attaches the pump to the perch and the filer for the pump itself. Any help would be appreciated.

Thanks,

Scott

scott, it attaches to that same bolt your coil attaches to. you are missing a "L(ish)" bracket. on my car, it was simply an alum strap bent to fit. somebody obviously just made it.

do you have to put the reactors back on?

[1yearonLy]

I see, I'll have to jerry-rig a bracket. Ok, I can do that I think.

The spacers for the through-bolts might be a trick. They exist somewhere I'm sure.

I'm not even sure if I need that smog pump air filter but I'll keep an eye out for it.

I'll put the reactors back on if I have to, I have them still along with the EGR stuff. It's not terribly complicated as I don't have the oil line interference or cat converter issues.
