My Saginaw conversion

[NMfjCruiser]

I couldnt wait for a kit any more, my pump (rebuilt,lasted about two years) was leaking and groaning.
Plus I thought the kit would be expensive and I like to work those things out on my own.
I needed to keep the smog pump for now so I decided to modify the Toyota power steering pump bracket.
I found that essentiall all you need to do is relocate one of the mounting holes.

I increased the flat area then welded a plug in the existing hole and re drilled the hole where it needed to be.

I then welded an extension to the back bracket so the pump could be bolted in from the back as well as the front. That's probably overkill as it was very solid with just the front bolts.

This is awesome, I think I'm going to do this. What are you doing with the pulley?

While I was at it I pulled the radiator, it had some slight seepage. A couple of years ago a "reputable" local Toyota shop did the head and I'd asked them to replace all water hose at the time. They replaced all the ones you could easily see!
So I did the rest while the radiator was out ( one hose off the water pump was ready to blow, most likely far from civilization) All new Toyota hoses now. I use German hose clamps that have rolled edges and don't cut into the hoses, I get for next to nothing at the wrecking yard (I pull them off the Mercedeses)

The Saginaw shaft is 3/4 so I just bored the Toyota pulley. Its a press fit, I have it marked and will see if it slips at all.
I could machine a key way into the Sag or just use a tack weld as some have suggested.
For better alignment I flipped the pulley front to back.
The high pressure hose screws right into the Saginaw if you get a pump from about 76 on, that when they changed to the metric fitting.
I replaced the other hoses with some quality 3/8 all purpose hose.

The pump fits quite well. I had to bend the tab on the metal vacuum lines in just a little.
The steering feel seems about the same and it's quiet as can be.

It took several days. For one because I pulled the radiator and did the hoses but also because it's been 100f here I just don't feel like working too long in that heat. Of course the engineering part of it takes time too. Figuring out how to space the pump so the belt would line up and it would be square. Knowing what I know now I could do this in an afternoon, especially if I had an extra Toyota bracket before hand. One thing I like is that if someone saw the need they could easily go back to the stock pump. I hope my power steering woes are behind me.
