22R Power Steering
22RE Power Steering
Converting 22R to Power Steering
Adding Toyota OEM Power Steering
Just throwing this out there incase someone finds it in a search.
As far as I know most Toyota's in the 80's with the 20R or 22R didn't come with power steering. LAME! However, its easy to add, though I'm surprised I've never found any information on it!
I have a 1987 Standard Cab, shortbed Pickup (IFS) with the Carbureted 22R motor.
I would imagine this would work on the 20R (depending if theres the same mounts for the Power Steering pump on the 20R head). And ofcourse the 22RE this works fine, well its my understanding most if not all 22RE's came with Power steering? PLEASE someone correct my assumption if its wrong. =)
I got an almost complete Power Steering setup off of a 1988 pickup with the 22RE.
1. Power Steering Box. 'PS Box'
2. Power Steering Pump. 'PS Pump'
The Air Valve on the PS Pump is used on the 22RE, the two vaccum lines hook into the EFI intake. However us folks with the 22R don't have this. Apparently the lines are to regulate how much support your steering gets depending upon how the engine is performing. I read somewhere when I was researching this that at highway speeds this valve makes the Power Steering less efficient and at low speeds it increases the power output.
I tried to find a bolt to plug the hole but gave up and just used two vaccumn caps (get them for a buck or two at a parts store) to cap the connections.
3. Power Steering Resevoir. *Picture Below*
4. High Pressure line from the PS Pump to the PS Box.
5. Line from the resevoir to the PS Pump.
6. Line from PS Box to the Resevoir (return line).
7. IFS Pitman Arm.
8. PS Pump and idler Pulley BRACKET (important).
9. LINE COOLER (mounts behind grill, infront of radiator).
The bracket mounts to the front of the head and to the side of the head. It has a idler pulley (used for tightening the belt).
What I didn't get and needed:
NUMBER 2 (No. 2) Crankshaft Pulley.
4 OEM bolts for the pulley.
$80 for the pulley and bolts from the dealership. I couldn't find the right bolts at any speciality bolt shop or any parts store or even in my bin of toyota bolts and misc parts I have going! .. They're only $0.86 from the dealer so just get em when you order the pulley!
The FSM refers to the pulley as the "No.2 Crankshaft Pulley" .. important when you tell the Dealership, it took them awhile to find it in the computer but I didn't let them give up! Though the guy was getting frustrated, hehe.
The pulley bolts to the existing crankshaft pulley, which has two pulleys. This third bolt on is needed to run the PS Pump.
The following pictures aren't very good at showing all the components but you may find them helpful as a reference. I had no idea where the resevoir went but if you look closely in your own truck you'll find the fender has indents where it fits.
This is to show how the lines hook to the PS Box. The FSM doesn't have a good picture, but the lines really only fit one way.
Installation is a breeze.
I had to remove the clutch fan to get to the crankshaft pulley to install the second pulley. Maybe you can fit a wrench around the fan, I didnt want to try. Besides with the fan out everything is easier to get to.
Drill 3 holes in the fender for the Resevoir. I got the bolts and washers from Home Depot to mount that. Like said earlier, there are indents in the fender where it fits.
My PS Box came with the pitman arm still on it, if you have to replace the arm you will need a pitman arm puller (get it at a tool supply store). Take the old Steering box off, put the new one on (no hoses connected).
Install PS Pump in the bracket (4 bolts, two infront, two in back) You dont need to remove the PS pump pulley, its a tight fit but the bolts will fit in there.
Hook up the hoses. The ends use a 17mm wrench.
Fill the resevoir with fluid (fill completely). Manually move the steering wheel completely to the left, then to the right. Repeat a few times. Fill the resevoir up again, keep doing this until the resevoir stops draining.
Start the truck, left right right left right left, fill as needed.
To fix the steering wheel so it sits level. you can pull the cover and undo the 19mm nut, pull the wheel out and move it a few teeth, fit it back on, tighten the bolt, replace the cover..done.
