1975 Emission Diagram for 232 6 cylinder

[cooperm]

I have a 1975 CJ5 with a AMC 232 i6 6 cylinder and carter carb. I lost all the emission control stuff. I would like to replace it but don't know what I need or how to hook it up. I would like to have a diagram if one is available. I have seen a lot of diagrams but non seem to fit my Jeep. They either have a different carb, engine or are for a different year. Seem the 1975 with the 232 was an odd setup. Thanks for the help.

Most 70's vehicles had the same basic system. You had an air pump that ran by a belt on the front of the engine. This connected to a diverter valve and then from the exhaust manifold to the carb with a diverter valve. Other parts of the system included vacuum controls, EGR valve, and a check valve. Here is a picture of what my 79 model looked like. I am also requesting to upload some general emission pdfs to the docs section. I'll let you know when that is done. Rod

Here's the authoritative source. The equipment varies very slightly depending on if you have a 49 state or CA Jeep. Don't quote me but IIRC '75 49 state Jeeps really only have the TCS system. No air pump, no cat, no EGR. I ditched the TCS on my 75 AMC 232 i6 . Runs stronger w/out it.

I posted a scan from a 1970's MOTORS repair manual a general guide to engine emissions. It is in the docs section. Might want to taje a look at it. Rod
