I just got done doing some other work and was able to get pictures of something that used to frustrate me about working on cars.

Toyota and others use something of a sliding clamping system on certain accessories like power steering pumps, alternators, etc. This system is often used to add stability and alignment to those accessories, and makes them very easy to install, but can be a challenge to get the part out for maintenance.

The tricky part is circled here in red. It is a lug of metal that is a press-fit into the aluminum wing of the timing cover, and is pushed toward the rear of the vehicle (left in the photo) until the shoulder hits that timing cover. Then you insert the pump between it and the front wing, tighten the bolt, and the lug slides across and clamps the top of the pump.

To easily remove the pump, you back the bolt out a few threads then drive it rearward with something that can provide some impact. I used a 1/2" extension against the bolt head to get through the spokes of the pulley, and a hammer against that. Note that there is plenty of room here because my radiator is removed. This is possible with it in place but will be a lot more tricky.

You're looking for the top bolt here through the pulley.

This will open up the gap and the pump can slip out once you get the rest of the bolts and such removed.

If you don't do this, the pump will seem locked in place, despite all of the bolts being totally removed. I've really struggled with this in the past before figuring out the trick.. hopefully this helps someone.

You're 3 days late. Could have used this AWESOME tip over the weekend LOL.

I really did try to get this up sooner but even then would have missed your pulley experiment by a day.

Next time…
 
Super helpful tech I hope I never need. ;) I collect all these great tips into a separate bookmark folder for when I might need them.
 
Thanks @bloc , exactly what I came here looking for
 
I wish I saw this tip before I did mine. For me the hard part was not getting the old one out, but installing the new one.

Yeah, pushing the lug back makes more room for the new pump to go in as well.

It’s actually a little easier with the pump out of the way as you can use spacers and the bolt to press the lug back instead of hammering on it..
 
wanted to ask everyone which brand steering pump they replaced with? OEM or other
I have a Lares 13878 but the return outlet is way too small for the factory fitting

OEM of course. I think mine was around $280 plus tax at the local Lexus dealer when ordering online.
 
Bump because I referenced this thread and would have been cussing at the pump for a while. I ended up going another route though. I couldn’t get the bushing to move on mine and ended up using the lower/short PS bolt and a stack of washers on the back side. With a couple turns it shifted over and the pump came loose.

Great option.. hadn’t considered that. Thanks for posting.
 
I may try this next week. I usually gentl— OK, aggressively— attack it with a curved prybar which sort of scoops the pump out of the area. But sometimes you meet a pump with barnacle–like power.
