Integrated? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

MY pressure hose to my power steering on my six banger has a slow leak where the frame and the hose meet. I went to the parts store to get a new hose and they asked me if it is integrated or not. I said that I have no idea, I asked them and they are just as dumb as me. (that was 4 parts stores that had no clue..go figure.) Anyways what is "integrated" is my hose integrated? thanks

not sure if this is what you mean, but I remember this question when I had a six... it has to do with whether or not the intake/exhaust manifolds are integral or not... really has nothing to do with much, but I remember getting asked this when I went to buy parts that had nothing to do with intake exhaust problems...

apparently there was a change to this style of int/exh setup in the early 70s(?).... I don't think it really matters, but you could pull the hose and take it in for match up just to be sure....

I think the books must list parts based on "integrated" status, never did figure out why, but in your case it shouldn't matter...

Integrated refers to the cyclinder head. Starting in 1975 250's came with an integrated head (a portion of the exhaust manifold is cast in the head). Unless you have a later model engine you probably don't have an integrated head.

I see now, my truck is a 69 but the motor is a 68, therefore, my head is not "integrated" with the intake, and my exhaust/intake are not "integrated with one another. thanks all

The integral system is the one that has two hoses going from the steering pump to the gearbox. LMC lists it that way in their catalog.

This fellow that ask if it was "integrated" may have actually
be asking whether it was "integral". I quote the Chevy Truck
Shop Manual page 9-13 under Power Steering:

"General Description

Truck power steering installations are divided into two categories;
the Conventional Linkage System and the Integral Gear System.
With both systems, hydraulic pressure is provided by an engine
driven vane type pump.

With the Conventional System (40-60 Series), hydraulic pressure
is delivered from the pump, through two hoses to a control valve
which senses the power requirement and supplies the needed
hydraulic pressure through two additional hoses to the power
cylinder. The control valve is a rotary type valve which is mounted
directly to the steering gear assembly so that the steering shaft,
valve, wormshaft and rack-piston nut are in line.

With the Integral System (10-30 Series), hydraulic pressure is
delivered from the pump, through two hoses to the steering gear.
In the integral power steering gear, the steering shaft, hydraulic
valve, worm and rack-piston are all in line and within a single housing, making a compact space-saving assembly. With this
system there is no need for a separately mounted control valve
or power cylinder."

I assume from the above that all C10 P/U have the "integral system".

I think the first system described is the one with the hydrolic boom attached to the steering system
