If there is enough slack in the tensioner side to allow you to offer up the belt to the camshaft pulley straight and then wrap it around the top of the camshaft pulley then the teeth on the belt should drop neatly into the teeth on the pulley.

{I don't know if my description makes any sense to anyone else - it barely makes sense to me  )

Edit - wrap the belt round the crank pulley and make sure the teeth on the belt and pulley have fully engaged. Make sure they stay engaged for the next bit. Pull the drive side of the belt tight and hold it with your fingers just above the centre line of the camshaft. Push the belt against the camshaft pulley and the teeth should just engage, if they don't then bend the belt slightly to make the teeth open up a little. Once the teeth have engaged then wrap the belt around the top of the camshaft pulley.

Thanks Andy.... I fully understand your explanation 

''Drive side'' being the side without the tensioner, correct?

So basically this is the way to do it without using the backed off crank method? 

I'm promised another timing belt next week 

[Andy H]

Basically yes.

Before you take the old belt off apply some pressure to the drive side to create a bit of slack.

Thanksfor all your help 

Moving the subject on...

What is a floating crank? I'm told this method cant be done with one that has a floater 

Sadly.... ive never even heard of this at college 

[Andy H]

I think they are referring to the (mostly French) engines with a floating crank pulley. They don't key them to the crank. The pulley bolt(s) are loosened when the belt is fitted then re-tightened when (if) the timing is correct.

One of the engineers at work serviced his sons French car (I was told the make but it was instantly forgetable) last year. He didn't have a good word to say about the timing procedure...........

Got you Andy. So floating crank is the crank version of fords cam sprockets. Ie the pulleys aren't keyed to the cam shaft and thus will go back on in any position?

so what's the procedure with them? Generally speaking of course? 

[Andy H]

I will ask him, I never saw the car and I think his son got rid not long after because his father said he never wanted to work on it again

[Webby the Bear]

Haha that sounds about right! Hate renaults in particular.

Ok mate thanks very much

Baby petrol fords have the same set up,cambelt pulley on crank spins freely

[Webby the Bear]

henry is that also with free spinning cam sprockets....so cam AND crank spins on smaller engine fords?

[Webby the Bear]

So basically, if you have crank pulley spinning freely and cam sprockets running freely then you 1 million percent need the lock kit.

yet, whilst having to use the lock kit I imagine its easy cos you just slap the belt on and spin the pulleys to remove the slack?

Yep,1.25 zetec lump everything spins free so locks essential

[Webby the Bear]

Cheers Henry.

So basically, fixed cam sprockets and crank pulleys. . . No lock kit required. Tippex to mark cam and crank, back crank off to allow tensioner to pull crank round and take slack out the drive side.

Any engine with floating crank, floating cams or both. . . Lock kit essential and pulleys loosened to take slack out of drive side?
