CHEVY HOW TO REPAIR REBUILD THE POWER STEERING

2000 Chevrolet Camaro

Steering problem
2000 Chevy Camaro V8 Two Wheel Drive Manual 64000 miles

Hello, i bought seals kit and power steering pump filters from http://www.rockauto.com. now i want to repair/rebuild the power steering pump of my 2000 V8 camaro, how do i do that correctly? do you have instructions with pics or vidoe? what tools i will need?

they always say that repairing or rebuilding the power steering pump is not cost effective and the repaired/rebuilt power steering pump will fail and leak oil just after a week from installatoin and use.

so i want to repair my P/S pump and i want it to last.

thanks for help.

Inspection
Inspect pump ring, rotor, vanes, thrust plate, pressure plate and shaft for scoring, pitting or chatter marks. Replace worn or damaged parts

Reassembly
Lubricate new shaft seal, "O" rings and all other components with power steering fluid. Drive new seal into housing with suitable socket. Assemble shaft subassembly with components in original locations. Ensure counterbore in center of pump rotor faces pump pulley.
Install shaft subassembly. Install remaining components. Press end cover in far enough to snap retaining ring into place. Install flow control valve assembly and related components. Tighten hydraulic union to specification

Pull shaft and bearing assembly out of pump. If removing bearing from shaft, measure and record clearance (if any) between shaft shoulder and bearing inner race.

Pry shaft seal from housing.
Remove flow control fitting from pump.
Remove "O" ring, flow control valve assembly and flow control spring.
Insert small punch in access hole, and remove thrust plate retaining ring. Using a press and 5/8" piece of bar stock, press against pressure plate hub until thrust plate is removed. Remove "O" ring, pump ring, pump rotor, vanes and 2 dowel pins.
Remove pressure plate using press (if necessary). Remove "O" ring from pressure plate. Remove dowel pin from housing. Remove "O" ring from sleeve. Working from pulley side of housing, drive out sleeve with a punch.
Reassembly
Press new sleeve assembly into housing. Install new, lubricated "O" ring into groove in sleeve. Install dowel pin into housing. Install pressure plate spring. Install new, lubricated "O" ring into groove in pressure plate.
Mark spot on top of pressure plate directly over dowel pin hole in plate to help align hole with dowel pin. Install pressure plate into housing, ensuring pin engages hole in pressure plate. Install 2 pump ring dowel pins.
Install pump rotor with counterbore (larger diameter of center bore) facing pulley end of housing. Insert pump vanes into rotor slots. With identification marks on pump ring facing upward, install pump ring over dowel pins. Install new, lubricated "O" ring into housing groove.
Install thrust plate, ensuring dimples in thrust plate align with mounting holes in housing, and thrust plate holes engage pump ring dowel pins. Press thrust plate into housing far enough to install retaining ring. Install retaining ring with opening centered on mounting boss nearest access hole.
Press shaft bearing onto shaft until clearance between inner race and shoulder is same as clearance recorded during removal.

I have some questions : 1- what tool I need to remove the P/S pump pulley? And where to buy it from?

2- do I need to clean the whole P/S pump prior to assembly? What kind of cleaner I have to use?

Thanks.
