Fiesta Mk4 1.25L Zetec Timing Belt Renewal

3 posts in this topic

Hi all, new to the forum,

Planning on changing the timing belt on 1998 1.25L Petrol Zetec engine.

Gathering tools and info at the moment and the info i have at the moment is as follows:

Bought Draper 61262 Camshaft/ Crankshaft locking tools, (Flat bar & TDC Crankshaft pin)

currently looking for flywheel locking tool for this engine,

currently looking for camshaft sprocket counter torque holding tool

considering on buying a Haynes manual for torque specs etc

As far as i know, the crankshaft sprocket is floating as well as the camshaft pulleys, So therefore i will need a torque wrench and an angular torque gauge for the crankshaft bolt, as well as for the camshaft pulleys.

I think i will need a flywheel locking tool for when i torque up the crankshaft bolt (without TDC locating pin inserted). I think i will also need a camshaft sprocket counter torque holding tool, (am i thinking its okay to leave the camshaft locking bar in place whilst using the camshaft holding tool?)

I have air tools to remove the crankshaft bolt as I've heard that it can be tough to get off.

And once i have fitted new belt, tightened all respective pulley bolts, align the tensioner to correct tension, then i rotate engine 2 revolutions then re-insert the timing tools to check.

Any comments or tips much appreciated.

Hi, think I'm going to buy a flywheel ring gear locking tool from Laser and remove the starter motor to fit this, just received the timing tools and Haynes manual for a bit of guidance.

I don't think i will try putting the car in gear and locking the brakes, i think that would damage the clutch and drive train to be honest.

All i need now is the camshaft pulley counter torque brace and a crankshaft pulley.

Once i get the TDC lined up with the locating pin then i can lock the flywheel and apply torque when i refit the belt, and as for the top end, i think i will fabricate a 'Y' joint flat bar with M10 or M12 bolts and hold the camshaft pulleys in place against the engine bay top support with a piece of wood underneath the holding bar.

Will post once i complete the work with pictures.

Thanks for reading.

Is the crankshaft pulley bolt a left handed thread on the Zetec engine?

Many thanks, Chris
