I,ve had a go at my pump today after all the warnings about pressurising a blocked off hicas section of the pump , this is what i,ve found .

After AndyGP had mentioned about removing vanes i thought i,d best open up the pump and have a look.

The pump looks to have two seperate sections that work sepearately from each other , front section powering the steering rack and rear section for the Hicas hence why there is a split feed on top of the pump .

It,s just the rear that needs attention , on previous threads it,s been said to remove the spring and valve which i have done , i then removed the backplate exposing the Hicas oil pump .

 

The top plate just lifts off this exposing the pump gear with the vanes in

Lift this out and shake the vanes out , it,s these that pump the oil

Now just put it back together and the rear section wont pump any more

As for blocking the outlet i just used the original banjo fitting , cut it off the pipe and welded up the hole in it .

Hope this might clear up a few things for anyone removing thier Hicas .

Just as a matter of interest mate, how long did it take to complete with the engine removed (and how does this compare to when the engine is still fitted?)

Is this the same as fitting an NA pump then?

seems alot easier to fit a NA pump

Oh cant you use a TT pump and join the pipes together. Sure the kit from z center shows you what pipes.

It,s a ten minute job with engine out , might be easier to remove the pump if the engines still in bud .

The Z Centre one does give you a joiner to link the pipes together at the back of the car , i,m removing all the pipe work so doing it this way completely disables the hicas side of the pump . HTH

Probably is but you,d have to remove the TT pump to fit an NA one so if your prepared to take the TT one is out you might as well do this :wink:
