Converting to Power Steering 68 c10 6cyl

[19673ontree]

I added power steering to my 67 then I decided to add air conditioning so I hunted and found pulleys that would add up to 3 groove off a 63 nova worked out perfect ,,

[sambudo]

Do I need to have a double pulley on my p/s pump? Or can i get by with a single pulley?

Also I have the pump off a 70 v8, and one from 74 Nova. I can mix these correct? I know everyone said try and get all pulleys from same vechile. I currently have double pulley on water pump and triple on crank. I found one for my alternater and possible p/s if i need to replace it.

Also was wondering if I had 3 groove pulleys for all, what would the purpose be if i didn't add A/C? Thanks

You don't need a double pulley on your PS pump. The only reason you would need a 3rd groove is for a/c. At this point, you really need to start mocking it up. Just mount the PS brackets and pump, put the pulleys on and see how everything lines up. Don't pull the steering gear until you have the pulleys figured out.

Well I now have everything needed. I went to install the ps bracket and the bottom bolt is given me trouble, it felt like it was going to break off. So I stopped, and have been applying kano kroil penitrating oil. Hoping to try this for several days and possibly try heat. Any other suggestions, that have worked for you?

I assume you're talking about the one that the rear brace bolts to? That one was a little bit of a pain. I remember soaking it with PB Blaster for a couple days, but it still didn't come out easy. I think you're on the right track with using heat if it doesn't come out after soaking for a couple of days.

It's looking good! How's the pulley alignment so far?

Pulley alignment on thedouble altenator seems to be great line up. Don't know about the ps pump until I can attach it. I'll try some PB Blaster when I get home. And post pictures soon. Thanks for the help.

The picture isn't my engine, thats just to show which bolts I'm refereing to.

here is the early '68 with power assist ram

question when taking off the fan, do i need to remove the fan to take it off or can ijust remove the bolts at the end? I nned room to get in and remove the stuck bolts. Thanks

Can you tell me if i need to do anything special to take the fan and pulley assembly off to get to the bolts with a ratchet?

see the two bolts at the top left behind the pulley, these are the ones that are frozen. The bottom one I need to get a ratchet on it. Do you think if I use MAPP Gas it will get it hot enough to make a difference? This is the only thing holding me up to ad on the p/s pump bracket. I hate it when everything is sgr8 then you hit a snag. Doing everything possible not to break that bugger off. Even made up 50/50 ATF/Acetone penetrating oil. From what I hae read this is the best concoction.

You just need to get the fan and the water pump pulley out of the way and you will probably be able to get the bolt out with no problem. The fan and spacer are 2 pieces that have 4 long bolts going thru and attaching the fan, spacer and pulley to the water pump. You will see 4 bolt heads on the front of the fan....loosen those and you will be able to remove the fan, spacer and pulley.

NC67CHEV thanks I appreciate the help, I got all bolts removed. No I will clean and repaint the fan and pully and reassemble. Then hook up the ps bracket and pump, attach the alternator. Make sure all lines up, then I can start to work on the gearbox.

On the p/s hoses for 250 L6, I am asumming they are different from the v8 ones. As the position of the pum in differrent location would need to be longer. Is this correct? Also on the Rag joint, is this a standard size? as my auto parts store is telling me there are two different OD's. Thanks

[Classic Heartbeat]

Just don't Mickey Mouse it and heat and beat the frame...
Do it the best way, and get a proper spacer for the steering box.

Spacers only work on 4X4s not 2X4s. WES

Yes, the 250 power steering hoses are different. I think I just went to Napa and asked for power steering hoses for a '70 model truck with 250 and power steering. I didn't change rag joints, so I'm not sure about that. Maybe there's a difference between 2wd and 4wd?

Thanks, looking forward to finishing up on this project! I'll take some pictures once i get the brackets on and pump attached.

Bummer everything seems to line up except the p/s pulley. any suggestions?

[NC67Chev]

Something doesn't look right about the way your power steering pump is mounted. Look at the two pictures below. I circled what doesn't look right on your picture and circled the same area on a picture of mine.

I think in order for mine to work I'll need that 3rd pulley. Shouldn't I be able to bolt on a third pulley?

can you look at yours an let me know which pulley it aligns with? Thanks

[NC67Chev]

My PS pulley runs on the 2nd groove of the water pump pulley. There's no reason you can't run it on the 3rd groove if you need to. Is the pulley spacing on the Nova water pump and crank pulleys the same as the ones you're using on your motor? There are some pulleys that have a wider spacing between the grooves.

[NC67Chev]

If you for sure need add on pulleys, I can provide you with those part numbers. However, we need to make sure that's what you need 1st. Did you keep the pulleys off of the other motor?

They look the same, but without measuring I can't say for sure. I have the pump from the 70 c10 p/u. The pulley is bent. I think I'll try abd put this in to see if it lines up with the 2nd pulley, coukd you tell me wht pulley pn you have on your pump? If I dont need the 3rd pulley that woud be gr8. But the way it is currently it looks like I need the 3 groove in my crank.

From other threads ut looks like the pumps might be more narrowed. Some seem to be not sticking out as far from the flange part of the pump. Not sure if im making sense.
