Needs to be atleast 3ft long, the tightening torque when putting it back together is pretty high.
I`m in the process of servicing a 2003 1.25 Fiesta for my lad. All was going fine until I started on the task of changing the timing belt. It hasn`t
been done and it`s over due so needs doing. I can`t undo the crank pulley bolt though. It`s stuck fast. I`ve had my breaker bar on it with no joy.
Anyone had the same problem and how did you undo it?
I can`t use the `breaker bar against the ground and turn it on the starter` method because it`s an non keyed crank pulley.
I also can`t hold the crank pulley with any tool to prevent it from turning because the pulley has no holes in it.
I`m gonna try removing the starter motor tomorrow and see if I can jam the flywheel. Alternatively I wondered about lowering the engine so the pulley
rests on a concrete block. The weight of the engine on the pulley may hold it enough to undo the bolt?
Any idea`s?
My brother in law had one (think it was a 1.4 so I dont know if its the same engine) and they couldn't shift it no matter what or how they tried apparently other people had the same issue - in the end it had to be taken off with a rattle gun.

A big hammer always worked for me but I remember a tip of threading rope through a spark plug hole to jam the engine. Did not seem a good solution to me. Also you have to make sure the piston is on compression stroke to ensure no damage to valves, maybe someone's tried this method.
Yes the old method no longer works for obvious reasons.
You will have to lock the flywheel with the proper tool that bolts into the starter mounting and use a very long breaker bar or a really butch
rrattle gun.
Put it in gear.
Put 4x2 wood in front or beind front wheel and tie down using straps or chain the wishbone.
As you turn pulley, car will want to move say frowards and over the wood but it cant go over due to straps/chain holding it down. Note. this is fine
using front axle eg land roverwhich a far stroinger than wishbone so dont blame me if anyrhing breaks or bends :p
Probably wanna be using a 3/4 in socket set, a 1/2 socket on breaker bar starts to bend in a worrying fashion.
But try rattle gun first.
You need to make a tool which holds the pulley using the three big slots in the pulley like this,

I don't have a rattle gun unfortunately. I can't make a tool as I've said because the pulley is totally smooth with no holes or slots
cut into it. Don't fancy the rope down a cylinder idea either.
I've got a couple of things to try for now. Thanks for the suggestions so far folks.
Time the engine up, get one of these , remove the starter and
timing tools, and bolt into the starter aperture engaging with the ring gear.
You should now be able to remove the crank pulley bolt with a breaker bar.
When you fit the belt and crank pulley with a new bolt, make sure that the cam sprockets can turn freely, as the crank sprocket can turn with the bolt
as it is tightened, this doesn't affect the timing in any way and is normal, but will result in a broken belt/cams if the cam sprockets are
finger tight with the cam timing bar fitted.
Also, some of the autodata instructions are suspect, especially with regard to these engines fitted to volvo's (2012 book), use the
ford
tis instructions - even they are no use for crank bolt removal without using a rattle gun (i've had several of these that wouldn't
budge with a rattle gun anyway), also i normally leave the flywheel locking tool in place for tightening the crank pulley, rather than relying on the
threads in the timing pin hole to hold the crank while tightening up as per tis instructions.

I tried getting the crank bolt of a 1.6 Zetec SE a while ago but it wouldn't budge.
Tried WD40, an impact wrench (did nothing), starter motor (socket kept falling off the bolt), butane blowtorch (not hot enough), Locked the flexplate
(snapped the 1/2" head on my 24" breaker bar).
In the end I cut the flange off the bolt with an angle grinder. It completely wrecked the pulley, but I had a spare scrap engine to replace it with.
Once I had most of the flange off I could undo it by hand. Made me laugh how easily it unscrewed after all the trouble I had.
Spent quite some time today using various methods to undo the bolt but it's stuck fast well and truly. Even a windy gun wouldn't shift it.
What a pain in the arse!
Gonna take the car to a garage to try a more powerful windy gun and if that doesn't work the angle grinder is coming out to play!
If you're not worries about destroying the pulley how about welding a bar onto it?

I replaced the timing belt on 1.6, used a flywheel lock as shown above, and 1.5m scaffold pole over a breaker bar. Was pretty tight, but came undone
What about a blow torch and heating?
That might break it free and allow you to remove it with a breaker bar.
As above, be careful with a 1/2" breaker bar/socket - they can and do shear off with little warning.
There's windy guns and there's windy guns , cheap ones are a waste of time and money. The problem with taking the car to a garage is you won't be able to drive it home.
