*#@! Power Steering pump disassembly!!!

[DTAYLOR]

OK, so who can tell me how to get that pulley nut off the power steering pump?

I cannot seem to find any pics of the overhaul, either.

Any help?

Thanks,

DTaylor

ps At this rate I'll have to remove a banana, or at least a half...

Pulley? My '97 is gear driven. Was the '96 different?

Or are you referring to the gear on the PS pump itself?

I mean gear.....see what happens when you get frustrated...

I used a 12-point socket...can't remember the size. But I believe that nut technically requires a SST; at least it looks like it from the way it's built. The 12 point will work though. Use a couple of wooden blocks (softwood like pine or cedar) to hold the gear in a vise. You'll want to make sure it's pretty snug in there to the point that the gear will be digging in quite a bit into the wood.

I used a gear puller (three-arm). Be sure you're holding the pump in a vise 'cuz in my case the gear popped suddenly and flew a couple of feet across the garage when it came off; would have been better if I had been able to catch it so as not to risk breaking a tooth.

Re the pics...do you have a FSM? There are pics and instructions for the rebuild in there; you really do need the manual for this if you've not done it before. Those little vanes are gonna be all over and you'll need to see how it all comes apart.

Dan,

good write up but I am doing seals in mine. I'm not sure where it was leaking by now. Maybe I'll just concern myself with the basic seals and call it a day.

I did look up the FSM page on Toyota tech, and it shows either a soft jawed vice or a two part "SST" which basically amounts to two half circle steel plates that will hold the shaft while the nut is loosened.

I put the gear in a vice, but like you I don't think it can possibly be good for the gear to tighten down on it that much.

I'm going to call the local hillbillies that run the Toyota store out here in Weatherford and try to borrow the SST or just have them loosen it for me.

Thanks,

DTaylor

You can use a vise if you allow the gear to embed itself in some soft wood. I did this with no problem. Just don't crank too strongly on the vise.

I realized that. I directed you to it because your primary question was how to remove the gear and that was specifically addressed in that thread.

As was mentioned, use wood between the jaws of the vice and the teeth on the gear. You can use an impact wrench to remove the gear if you want. You really need to at least check the tightening with a torque wrench though. Try to eyeball how far the gear is on the shaft before taking it off so you have sanity check for how far it should go back on. The shaft is tapered and it may seem like the gear is on when it isn't really seated fully.

Any difference in the depth or alignment of the gear--or any damage to it in the vice--will probably result in a harmless but annoying tapping or whirring noise until the gears wear in.
