Topic: Putting Power steering on an 80' w/ 20r (Questions)

[TheCookieMonster]

so ive searched and found out a few things about this. i have manual steering right now it it sucks. so im gettin ready to go ps and have a few questions.

i found a pump and resivior off of a 2wd 3rd gen. are these pumps the same as the 4wd pumps???and are all the toyota pumps the same?

also i see people that have ps on a 20r motor. anyone have any pics of the bracket for the pump and where the pump is located on these motors??

i think thats it for now. im in the process of gathering parts to do this so any help/advise would be appriciated.

thanks guys

the 20R pumps and 22R pumps are the same

the bolt to the side of the head just below the distributor, with a bracked that extends to the front of the head

cool...i need to go check my head and hopefully have the mounting holes for the pump bracket  ...im gonna pick up a pump and reservoir for $20 after work tonite...just need to get all the brackets, pulley, lines, new box

Your 20r has a 96mm tall block so you will need a 79 to 84 lower support bracket that bolts to the front of the block and the bottom of the ps pump.
The bracket that bolts to the head behind the distributor is the same from 79 to 95.

79 to 80 pumps used bronze shaft bushings and the high pressure hose exits towards the firewall. These early pumps have a poor service record and should not be used. I replaced the front seal many times on my 80 20r thur the years.

81 to 95 pumps use roller bearings and have a great service record. The high pressure line exits towards the drivers fenderwell and are available with a high pressure idle up port for efi or without. Both pumps will work just fine.

Save a lot of work by getting a first gen 2wd or 4 wd reservoir and after drilling 3 holes in the fenderwell, bolt it on. The 2nd gen trucks use a difference reservoir that is a pain to mount to the early trucks.

2wd pumps and 4wd pumps are not the same, the 2wds have a smaller sector shaft, and a king spline that the 4wd does not have... 2wd pumps mount to the frame with 2 bolts instead of the 3 the 4wd pumps use.....


also, if you get a power steering pump from a 22r, get it with the brackets, the pumps from pre 85 will not bolt up to a bracket from an 85+ 22r

jim are you a total moron? this is asking about PUMPS and you are telling him about BOXES.  no where in his original post does he mention a box.

Thanks Marlin,  i was looking at a  85 pump today and  wondered if the internals were different because the old trusty pump thats been in my truck since 1979   is finally starting to go,  i'll swap pumps sometime this week

cookie monster,  theres a "wishbone" shaped bracket that attaches to the bottom of the pump and goes down to a bolt on the front of the block just about mid ways of the alternator,  i didnt use this wishbone for awhile  and it tweaked my pump brackets , i guess the added leverage was too much for the upper brackets

i'll try and find pic's for all the brackets

is correct

You need to get me a pic of that glen    Since I have a 76 celica head on mine I don't even have the boss on the front of the head for the idler pulley bolt.  I made a half ass L bracket that went around to the bolt that holds the lift eye on the head, but had nothing going down so the whole assembly would kink down under hard throttle and loosen the hose.  It wasn't too bad as long as I didn't tighten it too hard, but I'm in the process of making a bracket that'll bolt to the side of the head and tie in with the a/c compressor mount.

ask and you shall recieve 


the hole made by the "Y" shaped bracket is where the radiator hose goes

[kneedownnate]

Weird, I've never seen one of those that I can remember    I'll hafta take a closer look and make sure I even have the mounting bosses for that!  I was envisioning a bracket that bolted to the passenger side for some reason    That's the side I was mostly concerned about because the celica head doesn't have the boss on the front where the bolt right by the idler pulley would go, so there's nothing on that side keeping it in place. 

I made a half assed bracket that wrapped around and tied into the bolt holding the lifting hook to the head and will still be using part of it, but will need to add a piece that goes down to the top bolt holding the a/c pump bracket to the engine.
