Hey guys. Hope this isn't a stupid question however I would like to know what this part is. Guessing it is part of the emission set up? Looking to perhaps do away with it including the emissions equipment. Does a 74 CA delivered car have a smog pump? I have read about them but I am not sure I have seen it where the belts are ? Before you howl in terror, I'm in Australia and I will be fine! No Federal offence!!!
i believe that is part of the air injection system. the hoses going to that should be going to the exhaust manifolds and the smog pump. you should be able to remove the whole system and just have to plug off the ports in the exhaust that it went to.
I love this forum. Thanks mate. Simple as that? Just blocking off inlets for that particular hose? Thanks.
I had a harder look and found the pump. Very surprised I didnt see it there but given I haven't even changed the oil or anything since she landed I'm not surprised. I also didn't realise because there is no belt on the pump so its non op. Given she runs ok I will do away with it unless there is anything else I should know?
the 2 hoses coming off the sides of part you circled are going to the check valves that go to the air injection manifold. you can just cap the check valves off but it will look better and make it easier to work on if you remove the air injection manifolds from the exhaust manifolds. you will just need some sort of plug. i think the holes are 3/8s course thread. i have use set screws with the proper thread pitch to plug these holes before.
Hey. I removed the pump and brackets and attempted to remove the hose from the passenger side air injection pipe. I removed it but also removed the whole end leaving me with a torn twisted pipe end. I now need to remove the whole thing from the manifolds to insert those bolts you speak of. I would do it but how do you get a bloody spanner or whatever around the nuts to remove them. And how do I contort my body to actually insert the said apparatus to remove the thing? ??? Just getting the valve cover loose was a chore because I thought it I removed the cover I would get more access. Wrong! While I'm here, how do you get that out easy enough too with all that crap around. The brackets to assist with the engine removal are in the way and you can't even get them off because the bolts are too long and wont come out because of the shock tower. Arrrrgggghhh. Rant over. Help please???
im sorry but i have not removed these in a maverick. a crows foot flare nut wrench like this should get into the air injection tube nuts. also put some penatrating oil on them and let it have 24 hours to soak. you could also cut the tubes off of the nuts and either fold the tubes over to seal them or you could then fit a socket over the nuts to get them off.
I might see if I can get hold of those flare nut spanners, preferably with an angle cause it is soon tight there. Might have to end up folding the tube as suggested though. I can see I'll be lifting the engine and fitting headers to solve the whole issue though! Can't help myself. Thanks for the ideas mate.
Hey. I ended up finally getting the air injection tubes off by bending the pipe away from the valve covers to give me more room. I also spent a fair amount of time removing the engine lifting brackets. I ended up cutting the bolts on two separate occasions for each with a hacksaw just so they could clear the shock tower and fall out. PITA. I purchased a set of flare nut spanners and they were great in getting them loosened. Thanks for the info. Now I just have to plug those holes and I will be free of the SMOG gear. The valve cover gaskets look to have never ever been replaced given the caked up oil and brittle cork gasket, or what was left of it. Given the amount of pipes and tight access were these gaskets ever changed? I couldn't imagine anyone charging anything but a small fortune to service the engine!
If you aren't that concerned with originality, I recommend trimming the shock towers. A search here will turn up some good ideas how to do that. It is very easy to gain a couple inches of working room on each side around the motor that way. It is far easier to change the plugs on my 351W swap with cut shock towers than it ever was with the factory towers and the 302. My towers were merely cut and flat plate welded in. In looking at some other cars that have been done, I prefer where folks have saved the factory contours and moved them outboard. It can look very original that way. Unfortunately, neither gives much more exhaust room ... the exhaust ports are right where the upper a-arms have to bolt to, but it will make working on the car a breeze. Something to strongly consider if the motor is out of the car at some point in the future. Off topic .... do you have to convert to right hand drive? Thought I heard that about cars brought into Australia ... that and some lighting changes.
Ooh. ...cutting shock towers! Might leave that one in the too hard basket. After getting the air rail and engine handle off it is much easier. Will be even easier with the ac off too. It's not even hooked up so I don't think I will miss it. No re right drive. Over 30 years we can leave them left hookers. I had a 70 GT Torino left drive for a few years and the only issue I had was high speed overtaking not being able to see past the car being passed prior to sticking it out. Yes re the lights. We dip down and to the left for headlights so they need to be swapped out. Blinkers need to be amber at the rear but easy enough to wire an amber bulb into the reverse clear lense. All that ahead of me! Thanks for the tip though. Never know what the future holds!
glad you got the smog stuff gone. that will make life working on the car much easier and it looks a lot better too. i bet that car gets lots of attention in Australia. i cant imagine that their are to many of this generation of maverick there.
No, I Haven't seen any big bumper cars out here and know of only a few small bumper ones. All alot nicer than mine but I have time. About the only attention she gets at the moment is people walking past my garage when im working on it. Hope to have it registered and on the road soon. Just need seats!
Hey. Could you tell me what I do with the hoses running to a stock air cleaner if I opted to go with an aftermarket open type one? I will keep the charcoal canister but there are a couple of others I dont know what to do with. Any help would be appreciated.
most 14" air cleaners come with a elbow fitting that can be attached to the base. the base will have a section it in that is stamped that can be punched out for the elbow. thats where you can hook up the charcoal canister. the other big hose should come from the valve cover breather. replace the breather with an aftermarket one with an internal filter. any vacuum lines going to it can be removed and caped off.
