Any idea what this thingy is circled in white?

 

It's in the spot where the cruise control transducer would go, it doesn't look like an original one but I'm not sure. Maybe it's part of an aftermarket type cruise system??
There is a vac line going to the brake booster line, could it be an electric vacuum pump for the brakes?? The engine have a high duration cam?

Otherwise...beats me what it is.
Somebody here will know for sure...or not.

 

Is that engine one of those Olds Diesel 350 converted. If it is that could be a Vacuum booster as Diesel engines don't produce Vacuum!!!

 

Or it could be a vacuum operated pump for air shocks

 

Nope not a diesel. Could be something to do with cruise control as build sheet says cruise control but when i received the car it was missing.

 

Looks like this thing is feeding right into the brake booster vac line. It could be an electric vac pump. If this car has a lot of cam in it, it may not have produced enough vac at idle for them to work well. Just a thought from how it is plumbed in.

 

That is an aftermarket cruise control servo. Has the vacuum line going to the back and off the round end is a cable that connects to your carb linkage.

 

Hard to tell in the picture but it could be just tee'd off into the brake line. if so, cruise servo would be it.

 

Looks like a cruise control servo/module to me. I've seen this model before but not sure where or what car.

 

If it is is for cruise control the part on the fender that controls everything is called the transducer, also called the regulator assembly on some models.
The servo is the vacuum bellows mounted on the engine that works the carb linkage and is usually connected to the the transducer with a vacuum line.

 

Thanks guys. SO it would be after market and not the original? What did the original look like? Any body got any pics?

 

Whats the application?

 

The CC on a 72 Looks like this, but yours is a 69? So it will be slightly different.

 

Hmmm - the label on mine looks EXACTLY like that one!

 

I have about 4 transducers if yours craps out. BTW, I was asking around to see if anyone would repro that sticker but can't find anyone who'll do it price effectively up here. I have one that is NOS (74 I think) that is like a gold/bronze tinge, the other NOS one is blue like this. The others are really faded out.

I haven't taken any of the 'used' ones apart or tried them out yet.

 

I will keep this in mind - I am sure I can use one for a spare. I have two now. One is nasty on the outside but nice and clean on the inside. The other is nice on the outside but inside looks like it went down with the "Titianic"...
Ironically, the one withthe nasty outside has the best label (the one you have posted (which is the exact one!))

I need to try to combine the two and see what I get.

 

Sounds good, the only thing you have to watch out for is the lateral bioscopic modulating valve on the lower part of the unit. If you don't put the coilover bimetal rotational variation detector properly onto the endoscopic vane, the planetary drive on the main shaft will not interact well with the command vacuum release and engage positions. This will cause fluctuations in speed and failure of electrical engagement pulse from the cruise stalk itself. One impropely installed endoscopic vane resulted in a severe crash. When NHTSA investigated, they determined the brake disengage pulse was diametrically interpreted by the archimedic locking thrust washer as a direct command to increase vacuum draw to the servo and throttle linkages. Got that?
