Before I get on the blower to uncle Albert.
If the crank and cams are locked properly & assuming nothings moved, do I still need to reset the cams?

And I suspect I know the answer to this, but is it a big no to use the crank locking pin to hold the crank while unlocking the pulley nut?

If nothing moves, I can't see any problems...
But, locking the crank is key to undoing the front pulley nut, as the nut is usually VERY tight.

When changing Donut's belt at Le Mans, Uncle Albert actually broke a socket...

My fear is using the crank locating pin to lock the crank and the breaking it in the crank while trying to undo the pulley bolt.

Uncle Albert often uses a BIG flat blade screwdriver, wedged into the starter ring...

Not sure what engine this is on but presuming its a Zetec is is my experiences with cam belts.

On my Silvertops I replaced the belt using first genuine Ford parts and later with a Continental belt. On both occasions it fitted with no adjustment needed to the cam pulleys.

When I replaced the belt on my Blacktop over the winter I used a genuine Ford kit. Before removing the old belt I fitted the crank pin and cam bar and the timing was spot on but I was surprised to find that it was about 1/2 a tooth out at the cam pulleys with the new belt, luckily I have verniers on this engine so adjusting is an easy 30 second job. I counted the teeth on both the original and replacement belts, it was the same. I checked several times when I fitted it and have checked again since and the timing is spot on with the crank pin and cam slots. Still mystified on this one.

On my current Blacktop install I don't have the front covers fitted so changing the cam belt does not involve removing the bottom pulley.

Yes 2.0l zetec,
now I'm confused, turned engine to tdc, fitted crank pin, remove cam cover, only ex cam has slot for tool?
And I assumed that would be in line ready for the cam tool to be inserted but its about 45deg out.

Doh!
Universal tool has arrived, doesn't fit.
Minimum gap it fits is 12.5mm between cams
Mine is 6mm.

Simply mark all the pulleys with a suitable product before you remove the old belt. After fitting new belt make sure all the marks line up exactly as before.

Worked for me several times on Golfs where there were no cam locking devices and the manufacturers timing marks were invisible unless you had the engine on a stand.

I did hear of a Zetec owner who made up a cam locking tool out of a bar that he bolted across the pulleys. Can visualise what he did but no idea if it really is possible, feasible or even worked.
