I found the power steering fluid trail the other day. My 4Matic light blinks (my mechanic says my Power Steering pump is weak and should be replaced.)

I have bought a seal kit for this Vicker 119 power steering pump - I have no manual. Any suggestions or comments on removing the pump and replacing the seals. I have been advised to carefully use a fabric pipe wrench to remove the front plate of the pump.

Thanks in advance for your thoughts.
