Removing power steering, manual rack needed?

[dorikin]

The only part inside the rack that could be considered to be lubricated by the power steering fluid is the piston o-ring inside the power cylinder. If you are converting to manual this no longer serves any purpose and can be removed along with the valves inside the valve body. Remove this o-ring and the breather becomes redundant: there is nothing to cause internal pressure and have it affect your steering feel. The breather+fluid setup's only gain is that it might preserve that o-ring in the event that you both (a) don't remove it to begin with because (b) you want to return to power steering in the future.

Hey mate I'm going to do this to a spare steering rack I have but just wanna make sure I know which parts to remove.

"Piston O-ring inside the power cylinder" - Is this the O-ring pictured next to the Cylinder Housing?



"Valves inside Valve body" - Do I remove the Cut-off Valve and 4-way Control Valve in this diagram?



Thanks
