PS Pump/Vacuum

I actually have a 1989-92 6BT vacuum & PS pump on my 4BT. They come with two vacuum bellows.

I'm wanting to put one of the newer vacuum pumps like 94-2K



I had to remove one vaccum bellows and cap it to fit inside my engine bay.

Contact me.

All of the 4B's I've seen use hydraboost for the brakes, no vacuum pump. I can't imagine why a P/S pump from a 4B would not bolt on the a 6B.

BTW, If you do go with a hydraboost setup you will want a pump from a hydraboost system as they operate at a higher volume and pressure that a pump from a non-hydraboost system.

Yep

Currently my Bronco is set up with power-vacuum booster brakes. The vacuum pump is the bellows type used in late 80s and early 90s Dodge pickups.

I have on-hand a hydro-booster for a project later to convert from vacuum to PS controlled booster. I have a brake system that will work. However, I also have the hydraulic hoses and ram for assisted steering. I still have the brakes and axle parts to install, so I'd like to get this thing on the road first. See how it steers and stops.



Yes, they are interchangeable. But the bellows will hit the fender-well on a early bronco. The engine compartment is full of cummins.

does that come with the resovoir and gear?

 

[Steve Graham]

That comes with the resovoir, no gear. I would think that the gear off of the 6B would attach to the pump?

A good place to find the unit (pump, gear and mount) is :

Avant Salavge

219 Waco Dr. / P. O. Box 228

Sandersville, GA 31082

800-553-8192



Tell them you want a P/S pump, gear, mount off of a 4B with hydraboost.
