Power steering conversion?
I am wanting to convert my 69 to power steering from manual steering. Yesterday I removed a power steering box, pitman arm, center link and idler arm from a 71 or 72 C/10 frame. My question is, are the center links and idler arms the same on both steering setups? I also picked up a powersteering pump off of a mid 70s 305 but after researching this site, it looks like it will not work without having to move my alternator over to the passenger side. I think that I have access to a correct style pump, so I am going to try to pick it up along with the mounting brackets. I am going to order new powersteering hoses for it before I do the swap. Do I need to purchase any other parts to complete the swap other than the pulley for the crankshaft?

Re: Power steering conversion?
Rag joint that fits the PS box and a belt. I never had to change center link or idler arm, just had to get a pitman arm for the PS box.

Re: Power steering conversion?
I am new to the site, but I saw your question and had to respond. I swapped my 1972 over to PS and did not have to move the alterator to the passenger side. I did have to find the right crankshaft pulley. I believe it had three grooves. I can't run out and check right now but I can make a call and have a friend verify if you need. Take a picture of the pump brackets as they come off. It wasn't immediately obvious to me how they went back together when it came time for reinstall. The only other things you may want will be the castle nut and cotter pin which hold the pitman arm on the gearbox, and loctite (R) threadlocker for the ragjoint nuts. I use in spots where you can't afford to have a nut come loose.

Re: Power steering conversion?
I also have PS and drivers side alt. It was done this way when they had AC. So with the right brackets it shouldn't be a problem.

Re: Power steering conversion?
if you were closer, I have a complete 71 parts truck with the pump, brackets, and pulleys you need to leave your ps and alternator on the drivers side.

Re: Power steering conversion?
Thanks for the replies everyone. I have access to a 71 parts truck that I know has a pump on it but am unsure of the brackets. It doesn't have an engine so I know it doesn't have the crankshaft pulley.

Re: Power steering conversion?
Did you get your install complete? Do you need info on the pulleys?

Re: Power steering conversion?
There is no reason to fool with the alternator. The alternator is supposed to be on the driver's side of the truck regardless of whether the truck had P/S or not. Here's my engine with the proper brackets.

Re: Power steering conversion?
When I added PS to mine I moved the ALT to the passenger side I used factory pump and steering gear box.

Re: Power steering conversion?
Thanks for the pictures. I went back this past weekend and the pump was still on the parts truck along with the brackets for it. However, I still need the correct pulley for the crankshaft and the bolts to bolt the pump onto the block. Are the bolts 3/8-16 x 2"? Any idea where I can get a crank pulley one before this weekend?

Re: Power steering conversion?
Where did you purchase that power steering pump? I am having a very hard time sourcing one with that style reservoir.

Re: Power steering conversion?
dujobu,
I bought my used GM reservoir from Kenny's Trucks in Mounds OK. The brackets were sourced from a local salvage yard. The gear box was also used from a salvage yard. I replaced the hoses from a local NAPA.

what pump did you use (length of pump measured from the engine block / year of pump / back set of pulley) if you have any of this info, I am having problems finding the correct pulley see attached photo. Thank you!

Re: Power steering conversion?

I have attached a couple of pictures of my set up. I used pulleys from a mid-1970's small block with a short water pump. You should be able to find the pulleys on V-belt small blocks of the 1970's. The front of the power steering pump lines up with the front of the harmonic balancer. Also, my balancer pulley has three grooves, but there is almost no space between the V-groove channels. I see yours has a space between the first and second groove, which might be the problem.

Thank you all I got it all fixed with the help of fellow forum member 60-63 with the correct pulley gm part number 3791943 this pulley lined right up with the setup that I have, I guess the reason that it was so hard to find is that it is actually a 6 cylinder pulley, and most people haven't seen a factory AC pulley setup. So hopefully in the future when someone has the same problem I did they will be able to fix it without going through and purchasing 3 different pulley like I did.

Re: Power steering conversion?
If you start trying to move alt from driver's side to passenger side, you will run into pulley issues, pass. side stuff was later model 73-up and used a long water pump, your truck has a short water pump. If I were you I would invest in the correct bracket set for a 68-72 truck and a correct power steering pulley- try teeitup and covert with no hassles. For the other portion of your question, you stated you removed parts from 71-72 truck and going onto a 69. You need to use your drag link and center section. The tierods are a different size on 72-72 and will not bolt on without converting to all 71-72 parts (good idea for disc brakes) . Summary- get right brackets and pullies and put pump on driver's side as originally designed. Use your center link and just change boxes if leaving drum brakes on your 69. Good luck.

Re: Power steering conversion?
I got most of the work done this weekend. The only I have left is to install the crank pulley, belt and top if off with PS fluid. I may have to made another return line going into the power steering box. I had to bend my inner fender up slightly to get it to clear the line.

Re: Power steering conversion?
I finished up my install today and I have a few questions/concerns. I filled the pump with fluid, jacked the front of the truck up and started the engine. I moved the wheel left to right about 20 times and turned off the engine. The fluid was very foamy and ran over. After I let it sit for a few minutes I checked the fluid level, and it was full. I started the truck again and I noticed that the steering in the left direction is much easier than the right direction. I drove the truck around my yard but the steering never really improved. The pump is a little noisy, which I expected, since the parts truck I got it off of has been sitting for a while. My question is, does this sound like an issue with the pump or the steering box?

Re: Power steering conversion?
Pumps usually make noise when they run low on fluid, but seeing how you said it's full and foaming I suspect either air that still needs purged or the pump is bad.

Re: Power steering conversion?
You were right. I thought that I had all of the air out of it yesterday but that wasn't the case. Today I kept the motor at about 1800-2000 rpm while turning the steering wheel left to right and I finally got all of the air out of it and it quit making noise. I have one leak at the steering box on the pressure hose side. I guess I will have to run it back out and try some teflon tape on it so see if I can stop the leak.

Re: Power steering conversion?
Okay. My hose is new, but I guess there is a chance that it is defective?
