I am adding power steering to my stock GM 350 motor - 69 Vette coupe, I am using a dual bottom crank pully and have no Air Conditioning. This power steering pump came with the car when I purchase it and will be hooked up to a steeroids rack. It would appear the shaft of the power steering pump is too long.

As with water pumps do they make short and long shaft PS pumps?

I have posted a picture below to see the distance. If the PS pully is bolted on it may align with a 3 crank pully, but I just can't see why this should be necessary... any help, suggestions or pictures of how this should look would be appreciated. Thanks!

 

It is necessary to have the third pulley. Corvettes had an additional pulley that fits into the crank pulley for three total. If you are using the stock PS brackets, you need the additional crank pulley.

Note how deep the single pulley is since it fits inside the double pulley.

 

You can barely see the third pulley at the bottom of the pic. (I have no second belt since I have no AC).

 

Your going to need the 232 p/s pump pulley but you'll also need to know what the part number is on the lower pulley. The 232 pulley will only mate up with the 013 pulley or the 838 lower pulley. Both are commonly used from 1963-1974.

3850838 PULLEY (7 21/64 0.D.)

It looks to me like you have the wrong power steering pump pulley, kinda hard to tell. But if you check the number on your lower pulley and it's one of the two above then add the 232 extension pulley it should line up with the power steering pump.

You can take this for what it is worth, I am no expert, and do not wish to pass on any bad info. I believe that the above mentioned add-on pulley was in order to operate the ac option in these early c-3's. It is my feeling that the pump you have pictured is a later model c-3 pump utilizing the pressed-on type pulley, which sets the belt alignment much further out than the original early c-3 pumps, which utilized a pump pulley held in place with a woodruff key. These keyed pumps and pulleys bring belt alignment in much closer to the motor. If all your other pulleys are original( and that is a big if!) than you should be able to run power steering with no ac, on the stock, two groove crank pulley. Hope this helps!

 

Willem.... ...

That is the nicest I've ever been treated when caught in an error! Thank you and yes... you are 100 percent correct.

All the pulleys I mentioned above are for a car with power steering and a/c. My error was I assumed he had a/c.

Willem & Willcox thank you for the information... I am utilizing aftermarket Billet pulleys but these are standard two groove. The PS Pump does in fact utilize a woodruff key and the pully is removable. I really hate the thought of having to purchase a three groove pully for the crank just to run power steering, especially since I no longer have the packaging for the two groove billet pully that is on the motor now...

 

Hi Mike,
As previously mentioned, I am no expert, but I will try to give you some help with your pulley dilemma. There are many areas that will foul up alignment, and if you do not have stock GM pulleys with part numbers, it can get expensive, not to mention extremely frustrating, to achieve correct alignment. Is your engine the original stock 1969 corvette smallblock outfitted with the correct OEM waterpump? The stock GM, Corvette specific waterpump outfitted with a matched set of GM crank and waterpump 2-groove pulleys for a 1969 small block, should line everything up. The problem is when you start with unknown components, it makes alignment a crapshoot, at best. It is hard for me to judge the distance that your alignment is off, from your photo. I will tell you , for sure, that there is a keyed GM pulley for high performance applications that looks nothing like the one you have mounted on that P.S. pump. It is not a stamped steel pulley, but casted, and when mounted, it cups in toward the block, bringing the groove alignment back toward where your picture indicates it is needed. Will it work? Did I mention the word crapshoot! I have the high performance pulley I am talking about mounted on my stroker. Look it up on Ecklers website, they have a pretty good database on these parts. Do a search for 1969 big block waterpump pulley, to get a look at what I am talking about. If you think that it may be your answer, take a measurement from the outer end of you PS pumps shaft to approximate center of groove in your waterpump or crank pulley that you are trying to align, and let me know what it is. Lay a framing square in the grooves of your crank and waterpump pulleys to make alignment easy to measure. I can then measure my big block PS pulley from end of pump shaft to its groove center, to see if distance is about the same. NOW! Have I got you totally confused

 

Yes, you need the cast iron pulley that fits a keyed PS pump to correctly line everything up. They are discontinued at GM but they are being reproduced I think. I have a NOS one but not cheap.

 

Thanks for all the help and suggestions, I agree it's a bit of a challange...
the water pump is an aftermarket alum pump using billet alum 2 groove pulleys which are also not factory. I did some searching on line yesterday (Sorry boss) and found the cast iron pulley that you mention for HP applications. I did a search and Corvette America had one for 99.00 bucks, so I ordered one. I also ordered a three groove pulley from Summit just incase. I figure what the heck, I can always send back what I don't use. These parts should be in tomorrow and I am anxious to get them mounted and see if they align. Hopefully the cast pulley will work with the two groove crank pulley and I can send back the three row to Summit. Thanks again for the advice! This Forum Rocks!

 

I've got a similar issue on my 76. It use to have A/C but that was removed by the previous owner when he made it into a 383.
The crank, water pump and alternator all line up with the 1st row grooves (closest to the engine), The second row looks to be unused now, and the 3rd row on the crank should spin the power steering pulley. (3rd row crank pulley being the add on 14023153 pulley).

The problem I am having is that the power steering pulley lines up right in the middle of the 2nd and 3rd groove on the crank. I can either shim out the alternator, water pump & crank about 1/2" or find a way to adjust the power steering pulley. The power steering pump is not keyed and is a new recond from Lonestar. If possible, I would prefer to just use the the 2 grooves on the crank pulley and eliminate the 14023153 3rd pulley. It looks to be possible if there is a power steering pulley that moves the groove 1/2 more towards the motor.

The previous owner had a lot of shims an washers and had the power steering pulley installed backwards and almost rubbing the lower frame rail. Any help is appreciated. I can take pictures if it helps.
