Zetec Pulley Grooves Quandary
G'day LCB-ers! Especially those who have installed a Silvertop version Zetec.
In preparing to fit the smaller Denso alternator, I have fitted a Retro-Ford kit, which was specifically for the silvertop. I noted that the drive
belt, which came with the kit, has 5 ribs, which suggests that it should fit into a 5-grooved pulley.
Braving the freezing weather, I went to my lock-up, to collect a few tools, and checked the existing water-pump and crankshaft pulleys on my engine.
They have 6 grooves! I suspect that if I tried running the 5-rib belt on these pulleys, there would be a few problems? Has anyone experienced anything
similar? Are the rubber belt ribs same size for both belt versions?
I know the simple solution will be to buy a new 6-ribbed belt (which I probably will do, but...).
Work-in-Progress: Changed to Zetec + T9. Still trying!!

Its quite normal to have spare ribs on pulleys even on production cars.

Its not a problem. I had similar on my recent blacktop install. As long as the alternator pulley is mounted in line with the other pulleys it doesnt
matter as long as the belt is running parralell to the grooves. I have a 5 rib belt and i have two spre grooves on the crank pulley and one ont the
retro ford pulley.
As i said, as long as the belt is running in line it will be ok!

Agreed, my belt is 5 ribs and pulley is 6 ribs, no problem at all, rib spacing is the same.
I have a Silvertop 1.8 Zetec
Why do they call Port Harcourt "The Garden City"?...... Becauase they can't spell Stramash.

Guys thanks for your feedback, and the reassurance. All I have to do now, is to change over the alternator pulleys. Which takes some doing, dunno what
the original tightening torque was, but haven't shifted it so far.

Pulley in vice, beautiful assistant to hold alternator and long bar on bolt. Has worked for me a few times.
Failing that rattle gun instead of long bar has always worked.

I've only got a 5 rib on the Denso with a Zetec black top. Works fine. Also gives you some choice for getting the best alignment.
To clamp the pulley for removal I've wrapped an old ribbed belt around it before putting it in the vice (to protect the pulley in case of need
to re use).
