I have to say to all you doom merchants ,sometimes you have to work with what you've got, Chrisgixer I did use the locks but you have to take them off to put the timing setting plate on!

I have a busted pulley miles from any decent stockist what can you do!

Anyway I concur with the advice to start at the top cam and belt marks and work down, making sure the timing is spot on at the top on these late V6's. There is also less to undo and remove compared to early ones, i.e. electric throttle and air pump changes.

Very happy to get it done, if it blows I'll be sure to let you all know!

Yes, I know.

But you did say, you moved the cams manually, which might imply, no locks. I envisaged an incomplete locking kit, as there's no reason to move the cams by hand normally.

Thing is, as you most likely know, its all got to be done again to replace that roller.

Hence acquire the correct kit. If that means re assembling as is, with no other car available, then that's what you have to do. I guess?

But whatever, you need the correct kit.

[chrisgixer]

Glad your sorted though.

[frenchtony]

Hi Chris, it was the correct kit, but yes thanks for the advice all sorted now, or maybe for now!

Sorry yes, something sheared..? Apologies I've not understood, what broke?

That pulley centre has been rotated the wrong way to apply the tension. If the engine is used as photographed the belt tension will rotate the centre anti-clockwise which will loosen the centre bolt.

The arrow shows the direction the centre should be turned to apply the tension.

It was the lower pulley so photo posted above.

that was how it was already assembled on the backplate? Surely it won't move now it's been torqued up? Now you've got me worried, how can you tell it's the wrong way?

thanks

.... how can you tell it's the wrong way?

thanks

The pulley is eccentric part of the bearing centre is sat around the 1 o'clock, if it'd been tensioned as per the arrow on the front, it would be more like 11 o'clock

Sorry. I don't want you to lose sleep but if it saves you from bending a set of valves then OOF will keep another Omega on the road a little longer.

Hi Andy
I'm not sure what is wrong, sorry to be a bit dim but I did follow the dvd guide? Can you please treat me like an idiot and give me step by step?

thanks

[symes]

in your last picture--the arrow on pulley is roughly at 1 o clock position---should be at 11 o clock position---if left as per photo--chance it go loose

It will be fine, provided it doesn't come loose.

But ideally, the eccentric should be adjusted in the direction of the arrow, because, if it does come loose the belt travelling in a clockwise direction will keep some tension on the eccentric and hence the nut, so its less likely to come loose all its tension.

As it is, the tension on the belt is trying to undo the eccentric, and hence the nut.

[frenchtony]

so its an odds issue, do I take it apart again for this in the morning or do I take a chance, I only changed the belt as a precaution as its new to me done 80K and nothing in the service book, guess its a couple of hours work. Would you do it if it were your's

[Broomies Mate]

The general consensus is that the belt is good for 80-100k miles.  It's the bearings which fail well before that.  If a jobs worth doing...................

Yes. No question.

The way the eccentric tensioner tends to tighten the centre fixing bolt is quite clever. Unfortunately it will tend to loosen yours.
