3.2 Power Steering Pump Removal?

I'm in the middle of a 3.2 to 3.5 swap on my 99 Passport. I've got all the accessories off the engine in the Honda except the power steering pump and the A/C pump. Everything I've read (my Haynes manual and Alldata) say the pulley is bolted to the pump, and must be removed before the pump can come out. My pulley looks pressed on, has no bolts or nuts on the front center of it, and it won't clear one bolt for the bracket. Getting a little frustrated on this one, any ideas? I know the obvious answer is to get a puller and take the pulley off, but I really don't want to do that, except as a last resort.

That sucks. What about getting the pulley back on the pump?

I have an Isuzu factory service manual for a 2001 Rodeo,which of course has the same engine as your vehicle.
The removal procedure for the PS pump in this manual does not require removal of the pulley. Looking at the
illustration in the manual, it seems to depict 2 bolts holding the pump to the bracket, and 2 bolts holding the
bracket to the engine. The removal of the AC pump does not require removal of the pulley either. The illustration
for the AC pump shows 2 bolts holding the bracket to the engine and 2 bolts holding the pump to the bracket.

http://www.myisuzuparts.com/1998/781/4/ ... parts.html shows the same illustration for the PS pump as the FSM

These are the bolt sizes shown in the illustration
10 X 100 7A
8 X 25 7B
8 X 100 29A
8 X 40 29B

Also note that on the illustration there is an earlier version pump depicted that shows the pulley is bolted on.

It's bolt #29A that's hanging me up. It won't come out of the bracket with the pulley on. I'll go out there and take another look, but hey, any excuse to make it to Autozone, right? P.S.~I have the later style pump, non-bolt-on, pressed on pulley.

the problem arises for everyone due to a lack of understanding on the bolts and how they hold the pulley.
three bolts remove pump, two short ones on right (as viewed from front of vehicle) an one long bolt (about 4 inches long ) on the lower left of pump(as viewed from front)
all three are accessed through hples in pulley. there is a fourth bolt behind pulley but not accessible through pulley. it is ti remove the braacket that the pump bolts into.

Now here is where problem occurs. The long bolt (lower left as viewed from front) screws into a metal sleeve embedded in the aluminum pump bracket. When bolt is screwed into the sleeve and tightened, it pulls the sleeve slightly out of housing forward against the back
of the pulley. when you loosen the bolt, that metal sleeve is still tight against the back of the pump making it seem a tight fit to take the pump out or put back in.
However, the solution is easy. remove the long bolt then screw it back in the same hole about half way so several threads are threaded into the back bracket. then place a socket on the bolt so socket protrudes
through the front of hole in pulley. This is so you can gently tap it with hammer to push metal sleeve back into the aluminum bracket located behind the pulley.
watch the socket for movement as you tap the socket. only needs to move 1/4 to 3/8 inch or so until pump is really easy to insert or remove. When you reinstall and tighten. it will pull back out against the pump.

the reason this works is that the bolts are flange bolts and socket pushes bolt when hit. if however, someone has replaced factory bolt with nonflange bolt, you can use short socket extension instead of socket and tap with hammer.

There has been a lot of misinformation on how to remove this pulley, hope all goes well for you and others.

Quoting an old thread, but this is very useful and works like a charm. Went in from the top, fan removal not necessary; used deep well sockets to remove the bolts and a short socket to tap the sleeve back in as indicated above. The large left side (sleeve) bolt is 14mm, the two smaller right side bolts 12mm. Awesome hack. Thanks.

Tried this and was able to get the pump loose, but I still can get the pump out. It wiggles but the back of the pully hits the 4th mentioned bolt head that holds the bracket on. Can only move it up and towards the right/driver side. Or is it that I can remove the pully after bolt is hammered back? Any suggestions? Pic below

Sorry I forgot to mention it - I removed that top bracket bolt; my pump was banging into as well. Should come right out after that.

Hello Campers!
This was most helpful solving my challenge in getting enough clearance to remove the timing cover though still a puzzle I'm sure when time to reinstall.
Thanks again for you knowledge!
