Need help, timing
Bruster - 14/9/24 at 10:35 AM

Hello all,

I’m new to this, while changing my timing belt on my blacktop zetec
My timing tool fell as I was trying to unbolt a stubborn bolt

A a result my timing is off..

Have I stuffed up my engine, is there any instructions to restore timing?

Engine if the car.

Thx

What timing tool are you using?

There is a Laser timing tool for the Zetec. It has 2 parts 1 slots into the rear of the camshafts to get them lined up, 2 screws into the block to place the crank.

yes, i have that tool

it was my fault for not securing properly.

is there a way to re time it?

i changed seals on cam shafts so the pulleys were loose at the time

Thanks, yes the video is good.
It’s shows the procedure but I need the procedure of how to return to timing if the engine is off timing.
At the moment if I turn the engine I believe pistons and valves collide

What moved? crank or cams?


Bruster - 14/9/24 at 02:28 PM

cams moved


Schrodinger - 14/9/24 at 02:34 PM

The strip of steel that slots into the back of the cams only fits in one way so if you turn them back they should line up and you can fit the bar back in at the correct point.
There should be a flat on each camshaft near the front of the engine that allows you to put a spanner on and turn the shaft in order to line them up.

Ideally if they're not far out so turning to 90 degrees BTC before unlocking cams is ok. Otherwise proceed with caution on the below. If you feel any resistance to turning the crank STOP (removing the spark plugs will make it easier to feel).

Unlock the cam sprockets (loosen the bolt and knock the sprockets loose on thier tapers) then turn the crank to 90 degrees before tdc or after tdc (whichever is closest). Adjust the cams to thier setting position and fit the cam tool. Turn just the crank to just before TDC (forwards or backwards but not going via BDC), fit the locking pin and turn the crank to it stop in the pin. Tighten the cam sprockets. Remove the timing tools, turn the engine 2 full turns back to the crank licking pin and recheck the cam tool fits.

2 questions before you do the above ^ ...how far out are they and did you crank it over?

Thank you guys, I followed the instructions of the last poster.
And worked.. engine is now timed and belt is in.

Woohoo… had me on the edge
