C2 crank pulley removal

Post by c.morewood »

Is this the first post on the c2?
I need to change the Crankshaft pulley on my c2 Hdi.
How do I stop the pulley moving.
With hte car in gear and someone holding the brakes on, the pulley will turn at least 1/4 turn making it difficult to put enough pressure on to release the bolt.
Any ideas would be appreciated
Thanks
Chris

Is the car in 5th? 1st Might not be sufficient to stop it moving

You can lock the flywheel, I've been told. Although I found 5th gear plus handbrake to be sufficient on my Xantia. Yes, the engine will turn almost 90 degrees but that just meant beginning the pull further back to accomodate it. The bolt is threadlocked and won't give up immediately but perservere with the pressure and it will slowly come.

there is a locking hole in the back of the egine going into the flywheel, you need to drop the flexible part of the exhaust to get a rod in it, the hole is specifically for locking the flywheel as you cant accsess the teeth, the hole is NOT for timing.

if this car has a dual mass flywheel, i have heard you are not to lock the engine by the flywheel, not sure but sounds plausable

i undid my freinds pully bolt with an air hammer gun

Thanks for all the advice.. I'll give it a go tonight. Although I might have to resort to my local garage for the air hammer gun!

Thats what this hole is for, there is a special tool (well its just a metal rod) for it on these DV engines, there is no access to the flywheel teeth unless you remove the starter.
As said already though air gun is the easiest way.

it may have worked, but surely you are still putting strain on the dual mass flywheel usueing that method, also i dont think you are ment to use the pin in the flywheel timming hole to undo the crank pully bolt

The DMF can take the torque of an engine turning at 4000 rpm, i dont think the force of the pulley bolt removal will do it any harm.
The reason its not advisable on some engines to use the flywheel locating hole to loosen the bolt is that sometimes it locates into plastic lugs which can break of if you try to use it to loosen bolts. if you can acsess the ring gear teeth then you can lock the flywheel from there no problem.

On the DV series engines (1.4 & 1.6 HDi) the hole in the engine block that goes into a hole in the flywheel to lock it is solely there to lock the flywheel to remove the bolt, It does NOT line the timing up to TDC. To set up the timing there is a seperate hole in the sprocket behind the crank pulley at the timing belt end.

ok wheeler
i stand corected, but if people are going to use the locking point in the flywheel, i would strongly advise they use a substantial rod, which would not bend whilst in the flywheel,

The hole is about 15mm diameter so its quite a thick rod & as you say it would need to be strong steel or similar.

Perhaps it would helpful if one of you experts could write a simple instruction sheet to help them avoid the potential pitfalls mentioned and post in the Handy Hints section?
