Right ill get straight to it ..

I have 2 zetec verniers im going to use on a ford ST170 engine one fits the exhaust cam fine it has a 10mm center ...

The other one needs to be opened up to allow a M12 bolt to pass through it to allow me to fit a VCT delete kit ...

It says you can use a drill press/vice and a hand drill .. i don't think that's a good idea or going to be very accurate and surely being the part that it is this is essential ?

Im open to your views on this ?

If anyone has a lathe ect and could help me out that would be great

A Drill press would be fine, as the hole is already centred.

But, If I were doing it I'd use the lathe, as I have one, 12mm drill then ream, if you don't get any offers more local I can help out by post...

Just one thought, what advantage do the verniers give, the none ST Zetec cam pullies are infinately adjustable, are ST's pinned or keyed?

Hi Pete thanks for your reply .. i Don't mind posting it ..

Im trying to delete the Variable cam timing on the engine so i have to replace the pulley if that answers your question ?

Ryan

Just out of curiosity, why are you removing the VCT?


Personally, providing the hole isn't centering the pulley I'd just drill it. If it's centering it I'd lathe it, too easy to knock it off-centre and it's pretty critical.

I don't know these engines but most cam sprockets locate on a boss on the end of cam and the centre bolt only job is to hold the sprocket on, if this is the case just drilling out in the bench drill should be more than good enough.

Thant all for your comments help ect ..

Britishtrident - im sure your right about it locating on a boss you should be able to see what im doing on the below thread on here ..

Thant being the case maybe a bench drill should be ok ?



Im deleting the VCT as my megasquirt 2 ecu can not run it properly only on/off after a chat with bailey performance i decided to delete the VCT .. This kit is made in hte states for the focus svt engine (same engine) ..

More info on that in the above thread
