Help.. Bent Woodruff Key.. Z22Se

Essentially the bolt for the crank pulley is off, but the damn crank pulley won't come off.. worryingly it also spins freely without whilst slightly off.. it's off about 10mm but can't for the life of me get the nadtard thing any further off..
Tried leverage tried to remove the timing cover but obviously can't...
Any advice or ideas as starting to loose all hope.. ðŸ™

you need to pull the crank pulley off, then remove the oil pump/timing cover, remove the chains and replace the woodruff key.
Brute force is required to remove the crank pulley.

Is there a set approach for pulley removal? I've only really tried leverage so far, there really doesn't seem to be enough space to physically pull it off..
Otherwise it's looks like engine physically out.. 😟

Therefore I would have thought it must be near to point of sliding off....

Almost wobble it side to side and it will come off.

another option is to clean out the M8 threads on the crank pulley and use three M8 bolts to force the pulley off

Only issue with using the bolts on the pulley would be that I'd be screwing against the timing cover as I haven't enough space to get anything substantial behind.. suppose maybe I could use a thin offcut of metal..

the bolts hit the oil seal raised section, ideally you should use some sort of flat thin metal to protect the alloy casing

I had a collection of rather large pry bars that didn't do the job.. got a monster crowbar and it slowly levered itself off..
Only remaining issue is that the remnants of the old Woodruff key appear to be bent / holding on the lower gears, but nothing a little chizling won't sort..
Anyone have a crank pulley knocking about?

I sold all my engine spares to member - evocarlos, which included two brand new crank pulleys, send him a message on here

Next issue, because I'm an absolute donkey I realised I've taken the chain off without the engine ( or bottom Woodruff key) facing tdc...
I can reassemble the chain, the cam sprocket on fit in 1 location? And the just crank by hand to check all marks line through?
Or have I fubard it? 😲

If you haven't turned it then you'll be able to put the chain back on.
If you have or aren't sure then put the pistons at the midway point and then turn the cams to the correct marks and then turn the crank to its mark and fit the chain.
The marks on the chain will take ages to line up if you just fit it and turn. (Hundreds of turns iirc)

Nope, I haven't turned it all..
Just taken chain straight off...
Woodruff key (which I think is TDC) is pointing to 3'o'clock.
On the basis that the cam' crank can only go in 1 place, and I can see the 'dot' on the bottom timing gear - Sounds like I will be ok then..

I would just reset the timing as if you were replacing the timing chains, it's quicker and then you know it's 100%

So to get it correct in my head.. rotate cams so they point in the correct place?
How would I rotate the bottom crank of the engine, screw the big big bolt back in and crank it over?
Get Woodruff key facing tdc..
I could rotate the cams separately, but surely to get them exactly correct then I would be going on links of the chains?
Getting out of my comfort zone slightly, but how could I ensure the cams are correctly positioned?
When I replaced the chain originally it was almost replace like for like and just checking the marks aligned..

For the crank take the spark plugs out if you haven't already and as you say use the crank pulley bolt to turn.

You don’t want to turn the cams and clash a valve with a piston. Here’s what I would do:
1). Check current position of pistons by checking position of crank with pulls and timing marks.
2). Confirm position by removing spark plugs and looking down each hole.
3). If still unsure, cut 4 pieces of wooden dowel the same length and drop them into each plug hole to rest on the pistons. This will show positions visually.
4). Rotate crank to get all pistons level - ensuring the highest go down and not up first to protect valves.
5). Rotate cams into no1 Tdc position - marks on cam sprockets will show this.
6). Rotate crank to no1 tdc, either by timing marks or dowels.
To rotate the crank, use a spanner on the crank bolt.

Make sure you get the crank in a position with all pistons mid stroke first before rotating cams....

I understand some of that, but can't quite get my head round all of it..
Can I cause damage if the timing is out turning bits by hand?.. i.e adjusting crank and cam position?
