not according to Zook

Check the belt alignment on the ps pump pulley as i pulled on mine to see if there was play but i couldnt find any, tensioner bouncing around was what gave it away and then i heard the shredding of serp belt .

there is no play on my PS pump we have checked that...more than once....
how can the tensioner bouncing let you know that the pulley on the PS pump is off when its not even the next pulley in line after the tensioner?

Oh by the way the one I took off never bounced but the one before that did...apparently they all have a little bounce in them but what is little to one might not be little to another

No help to you really but, Ive replaced the bearing in my tensioner, had a couple of belts on it (because of noisy belts), now running the orignal belt I pulled off after 2 noisy dayco belts, (one caused by cleaning engine), at no time has my tensioner jumped or had movement

yeah I know its strange.......

my less than 12 month tensioner that i took off after shredding a belt jumped......So put my old tensioner and old belt back on no jumping at all (but the nylon bush on the iner cicrle of the old tensioner has split...

so put my new tensioner on that a got in exchange for the 12month old one and that jumps a bit to

but the belts bigger that was what I was wondering whether the length of the belt is what actually makes it jump or not as I was wondering whether it could be as simple as the 5mm is enough not to keep tight tension on the tensioner

Well there was no play in mine and i noticed the tensioner bouncing wildly and then i heard the belt shred, it doesnt bounce otherwise so thats when i knew something was up - if 5mm or so of the ps pulley is visible then your pump is about to fail.

well the belt runs true........

but i'm still finding hard to understand how you know the power steering pump is failing just becasue the tensioner is bouncing? this is the bit you will have to explain to me.

are you just looking at your pulley and putting two and two together? how do you not know your tensioner hasn't just failed? just becasue it was working before doesn't mean that its just not working now

Steering was getting hard and with the bouncing came the shred, once the furthest most rib shredded off it was running as normal but you could tell by the alignment that the belt was hard up against the ps pump pulley inner lip and hard up against the fan pulley outer lip and about 10mm now of the ps pulley is visible so it is definately moving forward which indicates the shaft/bearing departing company as said in earlier posts. Either way its knackered but i am about to order a new 1 along with a t/belt kit and new serp belt from Island 4x4 and have them sent to our office in London near Heathrow and then airfreighted to our office here for 35 quid and will have them by monday at the latest.
