Power steering pump hot

Hi,

My power steering pump was getting noisy and I replaced it a couple of weeks ago.  I also changed the short, high pressure pipe that connects the pump to the line that goes all the way to the front.  I initially bought a new one from Brickwerks but foolishly stripped thread on it.  I got a local hydraulic shop make me a new one reusing the banjo connector from the one I broke.

I then went camping and as we travelled the pump was getting noisier and eventually the rack started making noise too.  The pump and fluid were getting very hot so I took the belt off and got home without PAS.  When I drained the fluid there were bits of metal in it...  I thought the rack must have had it so I bought a new one and yesterday replaced pretty much the entire steering system:

* new rack and rods
* new pump (didn't want to chance the last one)
* new lines back to front
* new filter
* filled with correct dexron ATF fluid

Most parts came from Brickwerks.

I just came back from a test drive and the pump is still getting. pretty hot.  I could barely hold my hand on it after 20 minute drive.  The fluid was getting warm too.   Is this normal?

I'm now quite suspicious of the pipe the local guys made me.  They put a restrictor in it, like the original had, but it looks a bit different from the outside (it's much shorter).  Could it be the pipe is too restricted?

My old pulley is a bit wonky, although not tragic.  I don't think that could cause overheating though.

I'm supposed to drive up to Scotland tomorrow for a weeding so it's a bit of a bummer.  Any ideas highly appreciated.  I'm going back in the shed to try and find my old pipe, which doesn't have a restrictor at all (that's why I replaced it in the first place) and try that.

Have you had front in the air and gone lock to lock to get all the air out the system?

I took my chances and started heading up north today.  Did around 3 hours driving and I'm currently camped near Leicester. 

On motorway speeds both the pump and the rack are getting pretty hot.   I can barely hold my hand on it for more than few secs.  It seems too hot for me.   It's a bit cooler when going slowly around the b roads keeping the revs down as much as possible.

If someone with PAS in their t3 could have a look at theirs after a long-ish drive and let me know how hot it feels I would really appreciate it so at least I have a vague reference.

I will be passing near Brickwerks tomorrow.  Might pop in and get a new, straight pulley just to rule that out but I'm clenching at straws.

Thanks,

Thanks.

I just had a look inside the fluid reservoir and there are fine bits of shiny metal in it... Something is grinding itself to an early death.  I'm guessing it's the pump.  I took the belt off and will have to continue without it...

I have not idea why this happened.  I replaced pretty much everything and was very careful to keep it all super clean and bleed the system properly.

The only parts I didn't replace are:
 * pulley (it is not very straight - could this be killing my pumps?)
 * pipe between reservoir and pump (had it made new 2 years ago so should be fine)

Could also be a bad batch of pumps? 

Found the Bentley diagram but it looks like petrol bracketry so it doesn't have the shim on there.

Ha. Will do vans been off the road sticking on a new turbo then the gearbox mount bushing failed. Will check asap.
