Knocking noise from the power steering

[reddy]

When you turn either left or right mainly on full lock and a bit in between i am getting a loud knocking/banging noise from the front of the car from the alternator/power steering pump area any ideas,i have just had the timing belt & aux belt & water pump replaced dont know if this has caused the problem. :(

Could be the PAS pump about to shit itself & die

Sounds like the belt isn't tight enough.

[reddy]

I hope its not the pas pump,how tight does the belt have to be and does anyone no what the correct size belt is mine says 6pk1025.

[Coops]

ai sounds like a skipping belt

get someone to turn the wheel for you and watch for it skipping on the pulleys in the bay.

[MatBrown]

Should be 6pk1013.

Also check PAS fluid levels. Top it up with slick50 PAS fluid, then lock to lock the steering to remove air from PAS system. Top up.

Only a small amount of play with the AUX belt should be evident.

Mat, coops you were both spot on ive never seen a belt jump around like that before,is there any easy way to tighten the belt without striping half the car down again. :(

[MatBrown]

What you might find is the teeth have sheared at the back of the adjuster.

as above, common fault

i got round it on my old clio by taking the small triangular support bracket off the alternator and spacing the main top one from the block using washers and a long bolt, but theres only so much slack you can take in so may have to get a shorter belt

otherwise its cut down an alan key and wedge into the adjuster pully and get a sleeve/rod onto it then spanner in there too. can be done without removing much, just a bit fiddly

Thanks for all the replys problem now fixed you were right about the teeth been sheared off 3 of the 6 teeth were gone so i just kept with the slighty long belt and it now runs fine with no knocking.
