use a tensioning tool that is the only way to do a yb cambelt.

i must be getting confused then cause I can’t work that out??? If I put to TDC two pistons are BDC and thus forces acting on cam, cutting the belt could cause the cam to move

locking the cam will prevent this
in my mind the tensioner is only once fitted??
am I missing something?
who cares about the cams moving just use a spanner to turn them back. Using a tensioner is the only way to set the cambelt tension.

i care because if you get it wrong I’ve written off a Ł30k car!
if you don’t lock the cams the cam will move and then how do you know what position it should be in? Tensioner does nothing but tension the belt when fitted it has nothing to do with timing

Why are you arguing with the experts if you don't feel confident just get a professional to replace your cam belt., The only special tool you really need is the puller for the crank pulley

You are, so to clarify you don't need a locking tool.
What Mark and grcossie have referred to is a tensioning tool, this is to ensure the belt is at the correct tension, as this is a manual process.
I would also advise you renew the tensioner, which is just as important as the belt itself.

From the scribes (assuming standard pulleys) else just mark them, as Mark says (no pun intended) so long as everything is correct when the belt is fitted.

i think I’m going to get ford to do it! Doesn’t make any sense to me how it can be aligned without a cam lock tool!
I would advise you use a specialist the people at your Ford dealer probably won't have ever seen a cosowrth in their workshop
i agree but I cannot find a garage I can trust, my local garage don’t want to do it due to the value of the car etc and they prefer to do mot, servicing and brakes etc they tend to not do bigger jobs anymore
there is a local specialist but I know so many people who have been to them with complaints that I won’t go to them.
id do it myself but I’m not satisfied I fully understand it. As in my mind you should lock the cams and count the teeth to make sure the correct teeth line up on old and new (on the belt that is)

Take a trip up the motorway to see Mark at MA Developments...job jobbed
Yeah and some after they found all amount of issues with it. And it will prob rattle afterwards cos most mechanics who don't know will time it up as a pinto.....see that so many times.
Most respected tuners will charge half that and do it properly.

If you can’t see the cams have moved a circa of 15dg you shouldn’t be working on engines.
the correct way to tension a belt is to turn the engine backwards.

ok....well I took the old one off with the engine on its marks and basicly followed the manual.. just without the tention tool...then rotated it manually a few times and did the 90 deg test...?

Ł530!! And you can guarantee if you took it to a main Ford dealer the mechanic who does it will never have done any work on a Cosworth engine!!!! I see that you have now found James at Autodynamic who has a vast knowledge of all things Cosworth related. Maybe he will also be able to help you with sorting out or removing that strange cooling system your car has got.
