Power Steering Issue

My pulley on my 67 is a little bent and throws belts if I rev on it to hard and so the other day it threw one, I replaced it and after that my power steering quit working. I just got the pump warrantied, replaced it and it still doesn't work. It's a little easier but nowhere close to what it should be. The gearbox and front end parts are also brand new and don't make any noises. My new pump gets really really hot after a short run around the parking lot. There's no noises or anything, any idea what it could be?

Power Steering

First of all the obvious; Fluid levels, belt tension and hose connections?

Did you purge the system of trapped air? The process involves jacking the front wheels off the ground and going slowly from lock to lock several times (engine on). The repeating on the ground while slowing going forward (to avoid scrubbing the tires too much in one spot).

Also are you sure you have a matched set of pulleys. A lot of older cars have had motor transplants. Chevy switched from a short water pump (with it's own matched set of pulleys and brackets) to a long water pump in 1969. If you have a bone yard 350 in your car it probably still has the long water pump pulley. Then there is the issue of the pulley itself. When they went from forward to reverse rotation water pumps they changed from a bolt on pulley to a pressed on pulley. Once again a new set of pulleys are needed to match.

It is because of problems like this that I recommend buying billet aluminum pulleys and brackets that use a serpentine belt, or bolting on a serpentine belt system off of a newer car taken off of a 305 out of the junk yard and buying a new water pump to match it. Not exactly stock but it is very reliable and since the manufactures of V-belts have stopped making V-belts to fit your car except for a very limited production run once a year a good idea. You can get five, six, or seven rib pulleys (the wider belts can transmit more power than the narrower belts found on low horsepower cars like the 305; just in case you want to bolt on a Procharger supercharger later on).
