Mk1 Focus Tdci Timing Belt Change
Posted 08 July 2012 - 09:14 PM
1. Lift front of car onto axle stands
2. Unbolt and move water bottle out of the way.
3. Remove rocker cover.
4. Put car in gear and turn front wheel until I can side cam lock bar in.
5. Put jack under engine and remove engine mount.
6. Remove timing belt cover.
7. Remove tensioner and old timing belt.
8. Fit new belt and tensioner.
9. Remove holding pin from tensioner
10. Remove cam locking bar and turn front wheel around a few times by hand and check with lock tool fit ok after each turn.
I was reading around and remember someone saying that you don’t need to lock the crankshaft as this shouldn’t move unless forced and that the injector pump does not need to be timed to the camshaft on the TDCI but only on the TDDI, so would this be sound advice?
Just a few more questions.
1. Do I really need the car on stands or can I just jack up on one side or do I even need to jack it up at all?
2. Is it better to rotate the engine using the front wheel or using the crack pulley?
3. Do I need to take any wheels off?
Sorry for the daft questions but any info on this would be really helpful guys as I don’t want to wreck all round me due to a stupid small mistake.
Here is a picture of what my belt looks like.

You can lock the timing wheel with a drill bit but the cam sprocket has to come off to allow for timing reset and this is done using a tool that only Certain garages and Ford has access to.
The bar you mentioned is used to hold the cam sprocket still while you undo the bolt, it's like a Y shaped bar with 2 pins on it.
Up to you though and it of course depends on how proficient you are at mechanics.
Personally i'd go the garage route.

the tools for holding the camshaft steady while you slacken the bolt are pretty bog standard, there are a few variants.
as for removing the camshaft pulley, its just a puller to remove it from the taper.

I'm really lost now, seems a lot of hassle to change one single belt from injector pump to camshaft. Oh well, looks like I'm gonna end up leaving it into a garage after all. Thanks for all the info guys.
as Clive has already said really, if in doubt leave it to someone who knows. for the £200-£300 it will probably cost it could cost you dearly should it go wrong.
Also buy the time you tool up, the savings may be minimal or not at all

If you end up way out then the resulting damage will empty your wallet faster than a divorce.

lock camshaft in position
remove belt and tensioner.
remove camshaft using suitable pulley holding tool - do not rely on the locking bar as you will bend the camshaft. there is a puller for removing the pulley from the taper but there are a few out there and any comprehensive kit will include one
thats you half way there.
the camshaft pulley should be refitted but not tightened, fit the new belt and tensioner and tighten the camshaft pulley - again using a suitable tool so you are not relying on the locking bar and damaging the camshaft
ensure you can turn the engine over with a spanner!!
