200 six Power Steering Pump

I have gotten some great help from forum members helping me to add Power Steering to my '66 200 Stang cvt. To date I have acquired the
bolt on crank pulley and the pump brackets. I am told the pump brackets are the later model for the 200 block. Possibly off a '68 Stang or '74 Maverick. I am need of a power steering pump and P.S. pump pulley. I understand there is something unique about the direction of the hose connections for the Stang Vs. other models. Any information about the pumps and pulleys that will work with the brackets and application I am engaged in would be greatly appreciated.
 
I purchased the Steeroids power R&P kit, but am holding for a pump. I thought I could use a 67-68 pump with the corresponding bracketry. I now have two pumps, one partial 6 cyl '67 bracket, one pump with brackets for a '67-'68, and no way to mount them. My block doesn't have enough bosses for the rear bracket, the one that the long pivot bolt screws into. Unles someone can give me some inspiration on how to proceed, I believe we need to wait to find a set of '65-'66 brackets and pumps. If you look elsewhere, you'll find a Sticky on the pumps.

As best as I can tell, the early '65s and back used an Eaton pump. That's the kind with the round external reservoir. The '65-'66 used a Ford pump. '67 until who knows when used a Thompson pump. The TP has many part #s, depending on how the filler tube and hose connections are positioned. The pumps are the same, but the reservoir cans are different. I don't know at this point if a Thompson pum can be fitted/mounted using '65-'66 brackets.

Bottom line, I think you and I are in the same boat, we need to locate some '65-'66 brackets, because the blocks will not accept the later brackets. I sent you pics of what the left side of my block looks like.
 
I don't believe we are as limted as you suspect. At least I hope not. I'll share with you what I think I've learned thus far. I still have a quite a way to go before I'll know for sure what can and needs to be done. I was able to acquire some brackets from Stranger53 "Randy" that he noted were off a '68 Stang with a 200. That said he pointed out that some of the bracket parts may have been from a Maverick. The cast piece that mounts to the two diagonal holes on the block seems to bolt up fine as does the larger plate bracket that shares the timing chain cover bolts. The large Aluminum pump bracket is still a big ? for me. I need to acquire a pump to see better how it all will fit together. Stranger53 explained that since we don't need to worry about AC or engine clearance with our 200's he thought we could use any Ford style pump. He believes the bolt pattern on the front of the pumps to be all the same. He also thought that any 1965-1969 model will have the correct male fitting size on the back. With that, I still plan to get a pump for a Mustang so I know the angle and direction of the fittings is less likely to cause a problem. I have a hardware mounting kit coming from NPD for the 200 '68 PS pump. I hope this will give me the correct hardware I need to get the brackets mounted to the block and a pump mounted to the brackets.
 
BIGREDRASA If you go to the Drivetrain, Wheels, Suspension & Brakes forum you will see a post by me towards the bottom of the list. There were some great photo's provided to me here. From the photo you sent me, I do not see a problem with you block's mounting point. It's the same as mine. Now if you have brackets for a 250 six, they will not work. I have been there already. In fact I have a nice set off a '77 Maverick if you know anyone that needs them.
 
Saw X21's pics. Great help. Looks like he used a spacer under the cast triangular rear piece. I have a pump with the bracket that cradles it, but the adjustment bolt hole doesn't match the slot in the front piece.

I have two pumps. One has the middle bracket and pulley. One doesn't. When I get rid of my latest respiratory infection, I'll go out and try taking some measuremements. Whe n I can figure out what's what, I'll be selling one of the pumps.

I couldn't tell if that was a spacer he added or if it was some kind of rubber bushing to maybe absorb vibration. When my PS pump hardware kit from NPD shows up I'll see if I lean anything about that. I won't be back it this until the weekend. I don't have the PC skills to post pics on the forum but if you send me you email address I can take pics with my phone and email them to you if I learn anything that might be helpful.

Maybe we'll find out one of your pumps will work for me. Do you have two PS pump pulleys for a 200 six or just one?

I will have to check back with Strange53 soon but from what I gether from his experience with installing the MPB integrated PS box system, I am leaning more towards the Steeroids Rack & Pinion.
 
I only have one pulley. From what I have gathered, it's best to get the largest pulley diameter, since the stock pump tends to overboost the R&P kits. Just based on my contacts with Steeroids, I think I'll be well pleased.
 
Curses, foiled again. My one pulley is bent. I'll need to shop for one. Chrome is kinda expensive (he says as he totals what he has already spent).

One big point of caution. Many have posted about the excess volume/pressure of the stock pumps overboosting the R&Ps. I've read various "solutions," except one of the easiest. Make sure you get a pulley with the largest diameter possible, such as 6 1/4". A smaller pulley, such as the 5 1/4", will spin the pump faster, and lead to more overboosting.
 
The Mazda RX8, as well as many other cars, uses an electric power steering pump.


Seems like that would be a whole lot easier...
 
Sorry to hear about your dissapointment with the Pulley. I would have thought that the PS steering was kind of a generic design and therefore would dictate only one pulley diameter. Your suggestion that we need to look at the dia. of the pulley so we can chose one of the largest dia. suggests there were a variety of diameters used. Do you know which cars/models used the larger dia. pulleys?
 
I'm still checking. I know many had 5 1/4" pulleys, and somewhere I saw/heard/read about a 6 1/4". The bent one I have is 5 1/4". Part of the prob has been trying to also purchase the proper mounting bracket. I know a welder who will make my current mounting bracket worik with the adjustment bracket. When a hammer won't do, the "Blue Wrench" will.

Kits for installing and removing the pulleys sell for as little as $11.99 + S&H, to $70 @ O'Reilly's. Nice thing about the O'Reilley's, you just return it for a refund when done. I'm going to see if I can figure out a DIY tool, courtesy of my local Fastenall Store.
 
I would be cautious about trying to adopt an electric power steering pump from a Jap car or a Chevy. These pumps are typically high voltage and can over load your charging system. In addition, they have been known to put a draw on electronic ignition systems adopted to cars that did not have them from the mfr. I would suggest Lithium Ion batteries dedicated to the electric power steering duck taped to the bottom of the fuel tank as a dedicated power source for the electric PS pump. This approach will no doubt save some HP as you want have the crank driving a PS pump.
 
Hey y'all let us know when and where you find a pulley for the stock power steering pump. Mine has a wobble in it, too. Mine is a 4 7/8", thanks.

I see no problem utilizing an electric power steering pump.

And I know plenty about 'lectricity and how to make all that stuff work...

If it draws a lot, you just need a bigger alternator. I would be extremely surprised to find one of these pumps ran @ anything higher than 12v, so I am not sure what you mean by "high voltage"
 
My neighbor is a professional Ford mechanic and he once spent a week in the hospital after being shocked by a elect. power steering pump on a '78 Fiesta with a supercharged 4 cyl. Seems the PS pump runs at 2,500 volts off the coil and is hooked to the MAP sensor so as to provide extra boost when above 10,000 feet sea level.

Clearly, you are high.
 
I've just spent a few minutes surfing for more anecdotal stories of electro-hydraulic power steering system problems/hazards. Couldn't find any. :?
