K19 A.I.R. Pump Identification

[Richard M.]

I have this smog pump and trying to decipher information and usage. It came off of a early 70's Jaguar but was a GM supplied part.

What applications was this used and on what GM vehicles? Was this a Saginaw cast part?

5696211 on case
5696132 cast iron backplate - also with a debossed 315(julian date?)

I cannot find these numbers in my reference catalogs

Thanks,
Rich

I can't identify it by casting numbers as these same numbers might have been used on different applications. I don't think this pump was ever used on a Chevrolet application, though, as I know of none that had a pump body-mounted muffler.

The backing plate was cast at the old GM Danville, IL malleable iron foundry which is where most AIR pump backing plates of the day were cast. That foundry is long-gone and, as far as I know, demolished and replaced by a power plant. The pump body was cast at the GM Bedford, IN permanent mold aluminum foundry. That foundry is still in operation today and casts many permanent mold aluminum components for GM, especially transmission cases and related.

Rich,
I saw this on eBay while looking for parts for my pump. I think it’s the same and he lists all of the applications... whether he’s right or not I don’t know.

As far as GM applications go I would opine that this was used for 6 cylinder applications. Note that the pump has only one outlet fitting on the backing plate. GM V-8 applications, except 66-67 Corvette, usually have two outlet fittings.

I believe this is likely a 1966-67 Corvette AIR pump. Note that it has "blanked off" outlet fittings on the pump backing plate and has the remnants of what was a "T" fitting on the pump body which served the outlet function. As far as I know, only 66-67 Corvette used this configuration pump. To be honest, though, I do not recall the T fitting and relief valve to have been on the same surface of the pump body but they may have been.

Ill get some more photos up in a while. Also, that muffler is removable and has a clip to hold it on.

Thanks for some great info on the castings. I thought the oddly shaped S was Saginaw.

I have an aftermarket Cardone Remanufactured Smog Air Pumps catalog (Oct. 1990) that lists Cardone # 32-112 for 1972-1982 Jaguar 6 cylinder models and #32-128 for 1972-1975 V12 models.
The #32-112 is also listed for 74-79 American Motors, 74-80 BMW, 72-79 Chev. & GMC trucks, G.M. Pass., 72-79 Chrysler Pass., 72-79 Dodge & Plymouth trucks, 73-79 International trucks, 79 Jeep, 74-80 Volvo.
There is no I.D. number cross reference or illustration letter listed for Cardone part # 32-112 or 32-128.

Usually, the muffler is mounted on the diverter valve. Some diverter valves have removable mufflers, others have mufflers that are crimped to the valve.

The stylized "S" does indicate Saginaw. The Saginaw Division of GM was the manufacturer of the pump assemblies. However, as is the case of many GM assemblies which include cast components, the cast components were cast by GM foundries that supplied castings to many GM manufacturing divisions. For example, the Danville Foundry, which provided the rear plate castings for many Saginaw-manufactured AIR pumps, also provided castings for many Corvette brake system components like master cylinders and 67-73 calipers. Among many other castings, they also manufactured the main bearing caps for 4 bolt main big blocks. The malleable/ductile iron poured by Danville was among the strongest of the cast irons produced by any GM foundry.

There were other AIR pump configurations used than just the ones shown here. The "32-400" style was used for 1976-79 Corvettes. I don't see any of the 1966-67 or 1968-75 Corvette pumps.

Re: K19 A.I.R. Pump Identification

This is great info thanks. Sorry no photos last night I fell asleep on the couch and never got back here.....

More details. Looks like the muffler came out of Germany or ?. SCHMELZER

But just did a quick google-up and it says a Ohio company may have made them? That S symbol may be them? Ref here.

What does that stamping represent, a serial # or date code of some sort? 06171A

I know nothing about K19 details so I'm learning.

Thanks,
Rich

Re: K19 A.I.R. Pump Identification

06171A is the Air Injection Pump build date code. It includes day of year, year, shift and model #

Rich,
It's the 61st day of 67, First shift, model A. Generally 67's had a P model and 66's had E as the model.

Thanks Ara I edited my post. Needed more coffee I guess.

And Thanks David L. for those images showing the model types.

I'm learning much now.

Joe do you think that S image at that Schmelzer Industries site may be that casting also or do you still think it's Saginaw like I first thought.
