Power steering fault - not working after new gasket fitted

Hi,
Ok here goes my story;
Noticed groaning noise when turning and opened the bonet to take a look around. Noticed PAS fluid was low and found that the gasket had gone on the PAS pump. So took it all out, replaced gasket and put back together. Filled reservoir tank up, released bleed nut, turned each side until it came through. However the steering is still v heavy. I can see the reservoir tank swirling around so I don't think it's the pump. Can someone confirm the bleeding process or know of an issue that may be going on?

Thanks

I thought they were self bleeding

they are

From RAVE:

Bleed
1. Clean PAS fluid reservoir around filler cap and
fluid level indicators.
2. Remove filler cap from PAS fluid reservoir. If
necessary, fill PAS fluid reservoir to upper level
indicator with recommended fluid.
+CAPACITIES, FLUIDS AND
LUBRICANTS, Fluids.
CAUTION: Ensure no dirt is allowed to enter
the steering reservoir when the cap is
removed.
3. Start engine and run to normal operating
temperature.
4. Position container to catch fluid spillage from
steering box.
5. With engine at idle speed, and an assistant
turning the steering from lock to lock, loosen
bleed screw on top of steering box. Keep PAS
fluid reservoir topped up and allow all air to
bleed from system. When fluid from bleed
screw is free of air, tighten bleed screw.
CAUTION: Do not hold steering at full lock
for longer than 10 seconds.
6. Stop engine.
7. Clean spilled PAS fluid from steering box and
surrounding area.
CAUTION: Power steering fluid will damage
paint finished surfaces. If spilled,
immediately remove fluid and clean area
with water.
8. Check fluid level in PAS fluid reservoir and fill to
upper level mark. If fluid is aerated, wait until
fluid is free from bubbles.
9. Fit PAS fluid reservoir filler cap.

I followed Hayes manual to the word but the power steering only becomes light again when revd above 2.2k.....

that would suggest poor pump

What u suggest, start shopping for a new pump?
Don't understand how changing a gasket has now caused poor pump. I do remember the new gasket being a lil tight to slip on, wonder if it's rubbing on the inside as its a metal/rubber gasket.

Slipping belt ???

I thought it may have been the belt slipping. Think I may have got fluid on the belt which is causing it to slip, I'll have a look when I next get chance. Cheers shifty
