haven't had a chance to have a proper look at the pulleys and cam on mine, but whats the easiest way to find top dead centre?

How accurate do you need to be ?

mega jolt trigger wheel accurate

What you need is a positive stop just before TDC , remove the porcelain and electrode from an old plug and replace with a bolt (being carefull not to damge the thread). Then simply turn the engine by hand till it stops on the `stopper` , mark the front pully , turn the engine in the opposite direction till it stops again , and mark the pully again . Exact TDC is smack bang in between the two marks - super accurate , and costs precisely nothing to do .

Oh , and to remove the gubbins from a plug - just cut around the plug , where it is swaged together , and simply tap out the porcelain .

cool! sounds easy enough
I'll have to see if i've got any old plugs laying about i don't think i have...
doesn't the pulley or the cams not normally have it marked? I normally avoid doing anything with engines. it usually doesn't wrork

There will be a TDC mark on the front pulley - great for a timing light , but no good for `static` timing as there will be a significant dwell period around TDC , where a few degree's of crank movement has no effect on piston movement .

would the mark on the pully be near enough for fixing the trigger wheel, and then use the advance on MJ to fine tune it?

I did mine [Zetec] with a dial gauge on No1, as I had one kicking about. Same principle as Claire's method..

Ooo - I wonder if TDC is in the same place on a 2.0 as a 1.8? I set the puley on the 1.8 and never checked on the 2.0. Seems to work Ok though.

Another job to do!
