STEERING TOO SENSITIVE

I have GMC Power Steering in my 40 Ford Coupe, powered with a 350sb chevy.

Recent 4-point alignment to eliminate "wander" problem. Car now tracks fine.



PROBLEM: Steering is too sensitive (too light or too "quick&quotto the point that I must drive with fingertips to avoid sudden lane changes.

QUESTION: Is there an adjustment/valve on the power steering pump that would rectify this problem?

SUGGESTIONS ??? please send email reply to me at JJFTIGER3@AOL.COM

Try John McLaren, I believe he designed the quadrasteer system for Chevy.

New Wire Wheels and Rims for your Model T

John McLaren, being an old car enthusiast and owning a Model T since the age of 16, searched for many years for a good set of wire wheels for an original 1913 Ames Racer (pictured left). Upon locating an original set of universal wire wheels, he was intrigued with the design. The universals did not need a special wheel center for mounting. The wheels that he manufacturers today are a redesign of those original universal wire wheels. due to a hgh standard of quality, this has led McLaren Manufacturing to start production of their own rims and accessories. All materials are manufactured in the U.S.A. and assembled in the State of Michigan. Over 100 sets of these wheels are on the road today!

If you are using a SBC power steering pump with a MII power rack, there are some valves you can get to reduce the pressure from the hard pumping SBC power steering pump to the low-pressure required MII power rack. Most of the Rod Shops carry these.



Now, that having been said...



If you want the poor mans remedy, pull out the fitting on the back of the pump that has the spring and pressure valve. Cut one full coil off of the spring, and washer out the valve from the PS pump body until the sensitivity is more "normal" to you. This is essentially what the aftermarket valve will do....though not perfect, it's cheap.

The trouble with fitting PS to a manual steer system is the gearing, the ideal ratio is 15-1 or less. You have 18-1.

I think unless you can make some major pressure reduction adjustments, steering will always become uncomfortably lighter the faster you go.

The info on pump adjustment is excellent & very interesting, I hope it works out! If not, try disconnecting it & put some decent pressure in your tyres.

Another thing that will help this is a hydraulic steering damper,although it's hard to mount one on one of these cars.

There is a shim kit out there that allows you to shim the valve to lower the pressures. someone by the name of Bills Hot Rods in Calif. sells them so i have been told. i need to look for him and do the same thing.
