Default need help w/PS pump leak

2009 RX350. Reservoir is empty and is leaking quite a bit at, what looks like, the pulley shaft. Serpentine belt gave out and may have whacked the shaft seal? I removed the hoses, wire harness, and 2 bolts through the pulley holes and the pump won't budge. Are there other bolts holding it on and where are they? Am I on the right track here? Is the seal replaceable if I pull the pulley or am I better off getting a new pump? I searched here and didn't find anything about ps pump leaks. Thanks all.

I looked at the picture of a new pump on Rockauto.com and it appears there are 3 bolts holding it on, not two. I think you may have missed one...

From the RX330 Repair Manual...
shouldn't differ from a RX350, hopefully this helps.

Thanks but it's different. There's no bolt going through the pulley and no bolts on each side...

My bad, the engines are completely different, but that slipped my mind when I posted...
I have an excuse, I'm a senior.
Hopefully someone who actually owns a RX350 with a Repair Manual or has been through the experience can help out.

No problem, I figured it out. For future reference:

Disconnect soft hose, regular hose clamp. The hard line is secured with a 17mm banjo bolt and one piece that holds both crush washers.

Remove 10mm bolt from bracket securing pressure/hard line

Disconnect the pressure sensor wire harness

Remove (2) 14mm bolts that are accessed between the pulley spokes that secure the pump. Then pry it back/down and out.

There is a shaft seal that got destroyed by a mangled serpentine belt. Picking up a reman pump from the parts store tomorrow, hopefully no drama putting in. Thanks again.

Great that worked out for you thus far.....
I am sure your findings will be useful for other RX350 DIY.owners.
Hopefully my RX330 will be the last vehicle I own in this lifetime, at least I have the Repair Manual to refer to.
