67 L71 Power Steering Pump Alignment
I can't determine what is wrong with the alignment on my power steering pump. When tightened, the cap is against the bolt that holds the brackets. There is no way to remove the cap without removing alternator and loosening the PS pump. Anything obvious to anyone?

Wrong length belt?

I don't think so. I put all new belts (suppose to be correct) on it when redoing the cooling system last season. Besides, full adjustment on the PS pump wouldn't get the cap away from the mounting bolt.

Bolt
If it is just the bolt that is in the way, consider removing the lock washer and using a star washer. You could also add a dab of LockTite blue on the bolt. That should give you the necessary clearance you need. Jerry

I'm not exactly BB educated, but I'll take a shot. If the forward pulley on the PS pump is empty, using a longer belt on the pump will allow the pump to move outboard. As is, even removing the lock washer, would not let the cap be removed because, as I see it the bracket is also in the way. Dennis

The brackets and bolts look correct, including the lock washer under the bolt that holds the pump bracket/alternator bracket/reinforcing strap. You might have the wrong pump reservoir even if the pump itself is correct. There is at least one thread by 1cerberus4u having one really bad time converting his 65 BB to power steering. Apparently some pump reservoirs don't have as much forward tilt to the upper part where the cap fits, and the fluid return hose fitting has different orientations for the various reservoirs.

Maybe the picture angle but that first picture shows the belt on the right side to be running at an angle compared to the edge of the pulley.

C.J.,
Thanks very much!! It does appear that your pump reservoir sits out further from the block and is shorter neck than the one in my car. If it's not too much trouble, could you provide a couple of dimensions? (1) from edge of cap to the bolt where mine is contacting & (2) the height of the reservoir neck with cap on.
I'm betting that's my problem.
Cheers, Larry

Thanks very much for the dimensions and photos. This last picture from the driver's side is really helpful. I will remove the pump this weekend and see what's going on with it. It appears that the reservoir neck isn't angled out properly. I have no idea if GM make different versions of these pumps. It appears the same pump was used on Corvettes from '63 through '74. Good weekend, Larry

Hi Larry,
I was perusing the Forum and read response #12 by GUSTO14 which may help to answer the question as to why your filler neck is so close to the bolt. It appears that some of the filler necks are actually tilted. It looks from his response that there were actually multiple pumps available with slight variations. You may have one of those variations.

I did a Google search, ('63-'67 Corvette PS pump) and found pics of two different pumps on Parts Geek web site. One had a housing that was oval shaped body and a tall neck like yours, the second had a perimid body, and a short tower neck.

I got the pump off and compared it to a pump that appears to be original that came off my 65. The neck angle and height appears to be very close to the same. I am sure the second one ('67) is a reproduction.

Larry, I have just been through this forest of installing PS in my BB car and I have a tread to detail the horror LOL...... After ordering some 6 or 7 different PS pumps, we came to realize that BB power steering pumps have a filler neck that is short, oval, kicked to one side of the reservoir and most importantly, tilted forward. The only place I could find them (besides that you can see pictures of them everywhere like on the rockauto site, ebay and such - yet when your order them you get a standard pear shaped pump) is from Lone Star in Tx. Expensive as heck, but it goes right in and works like Tom Brady....
If you go onto Rockauto.com and search a pump, I think its a Cardone A1 206086 or 206101 you will see a picture of it if mine dont load here...
From what I have found, this is the only pump that will work on a BB car...
Got mine finished yesterday....

After several months, I'm finally getting the '67 back together. The great folks at Lone Star Caliper were a great recommendation to fix my problem. I was actually able to speak with a technician and explained my problem. He received my old pump and examined it and called me back with the results and offered the proper pump to correct it. It now fits like the factory intended. The old repro pump neck was at the incorrect angle and he thought might have been a passenger car version pump. Anyway, this problem fixed! Onto the others! Many thanks to everyone that suggested fixes and to the good folks at Lone Star!

Glad you got it all sorted out! Where'd ya get a correct reservoir cap? Those seem hard to find. Most of the repops have a cap like in your earlier pics. They're $&$%$%-+%$!! to take off in that cramped space.
