Locking the flywheel 2012 C3 Picasso 1.6 hdi 90

I'm winding up to do a 10-year cambelt and water pump change.

Before I bought the Gates kit, I wanted to know if I could get the crankshaft pulley bolt undone.

Courtesy of youtube, I found the hole through which to insert a bolt through the gearbox casing into a hole in the flywheel to lock it. The problem is that although I could feel the bolt hitting the flywheel surface, whatever position I put the crankshaft pulley in, I could not find a hole in the flywheel. I spent over an hour trying.

In the end, I put the car into 5th, put the wheel on, dropped the wheel onto the ground, and managed to move the bolt. I assume the little bit of anticlockwise motion of the pulley before it 'bit' isn't going to do any damage?

The flywheel is the original - I've had the car from new.

So....do some original flywheels not have locking holes, or am I doing something wrong?

Photo of the hole location is attached. A rusty old bolt is in place.

Thanks in advance,

Ive not come across a DV4 or DV6 that doesn't have the hole for locking the flywheel. I know the original tool is quite a tight fit in there, i take it your bolt is a bit undersized?
I take it you are aware that this is just for locking the flywheel to loosen the crank pulley bolt & not for setting the timing?
It may be easier to get someone else to slowly turn the engine by hand while you try to wiggle it in.

Thanks for the reply.

That's the hole I'm using. Yes I know it's just to be able to loosen the pulley bolt. Most of the time I used an even smaller diameter bolt than the one in the picture. That enabled me to move the bolt from an angle to the left to an angle to the right to cover more of the flywheel at each pulley stop.

Some follow-up questions:

How many holes are there in the flywheel?

Are they aligned with the timing holes in the pulleys....in other words, if the holes are lined up for pins in crankshaft and camshaft pulleys should the flywheel also be lined up? Or are the holes in the flywheel random?

I'm guessing the custom tool is a snug fit so it doesn't droop in the entry hole and miss the flywheel hole?

Thanks again.

I dont think it aligns with the timing holes but to be honest i dont normally use it for loosening the crank bolt, thats what impact guns are for

Hi, I have a 2015 Ford Transit Connect with the T1GA / DV6 engine. Just done the first cambelt replacement but got to the point where the crank nut needs to be tightened & torqued. The 'autodoc' video & pdf suggest the crank / flywheel locking pin should be placed as per 'wheelers' diagram above. However, I also have wasted about an hour looking for a hole in the flywheel that isn't there! Do I really need to remove the starter motor to lock the flywheel?
Are these people using impact guns to remove the screws also using the same tool to torque the screws upon replacement???
