How do i set timing on Ford Focus 2.0 TDCI 2005 ?

Assuming the crank hasn't been moved you might need to turn it to top dead centre on cylinder one *before* fitting the head. (Pistons at each end at their highest points).
The timing mark on each cam is a 'dot' on the face of the cog. There will also be marked links on the chain itself that should be lined up with those dots. If you can't see the dots try looking at the back of the cog as it might have been fitted the wrong way round.
Some of the TDCi engines have lock pin holes fitted to each cog to trap it at top dead centre. You can use these as an extra reference method. (See Photo). The drill bits show the lock pin locations.

Set the crank to 0 degrees according to the timing marks on the damper, look on the cam pulley for a mark and line it up with the mark on the head. Put the belt on WITHOUT moving the cam or the crank.

ok did you follow the ignition timing and firing order set up correctly
did you turn either the crank or cam shaft/s with out the chain
did you do a compression test to check for bent valves

Timing chain or belt? Almost all timing gears have a dot that face each other when the timing marks are lined up. If you are not carful you can damage the valves while rotating the crank and came to the lined up position. However in a perfect world the top gear can be removed when it is lined up, and reinstalled with the chain or belt in place, it will be tight but you should not need to force it. good luck

If you havn't got the belt off yet mark the belt to the cam gear & crank gear & balance shaft if it has one with liquid paper. remove belt, transfer marks to new belt, refit new belt so all marks align & it can't be wrong.

Here is the trick. Align marks. Put the timing belt on the crank shaft pulley first, and after on the overhead cam pulley. Release tensioner and rotate the crank shaft till the timing belt makes two full circles. Try to align marks, you will be at least one tooth off. Align the crank shaft on the mark, and find out how many teeth you are off at the cam shaft pulley. Count the teeth. Remove the timing belt from cam shaft pulley only. Move cam shaft pulley in reverse according to the number of teeth you counted. Make sure the crank shaft pulley is on the mark. Mount the belt at cam shaft pulley.Rotate the belt two circles and check the marks. Repeate this procedure til after releasing the tensioner, and rotating the timing belt two full circles, the mars will be align.

There are no marks on this one. There is a special tool set to align camshafts ($900). The best you can do is to bring #1 cyl to TDC compression with both cam(valve) covers off. #5 cyl should have lobes at equal opening, exhaust just closing and intake just opening.. #1 cyl cam lobes should each be diametrically opposed to the positions of #5. If cams need to be moved, there is no registration of gear onto cam. Just loosen bolt holding gear and move cam. Retighten bolt. Roll thru 2 crank revolutions and check cam timing again.Simple.

crank shaft mark is a 8mm bolt in flywheel through bellhousing and cams is the flat on the on the end of the cam that has to be horizontial with the head

timing belts should be replace at 60,000 miles. ithe focus is a belt

please helpme i need timing marks for ford focus 2000 16 valvs
