Saying that, at 250Nm, thats friggin tight!

My Arm could tell you all about it, having removed it just... you can imagine how hard it is to remove, and stop crank turning!

CDX, ready for it mate, pics taken.

No possibility the crank has turned?

Stupid crap thing won't send...

Could be I really don't know anymore

Nope, nothing to signify use of a key or a keyway, apparently.

If I had access to someother publications, it could possibly confirm that the inner pulley is located on the tapered end of the crank then tightened quite a bit....

250 NM then plus 45 degress then plus 15 degrees.

As TB said, thats nipping it up quite a bit and, provided everything is clean and dry, should not cauase any movement problems....  

No explanation of where your bit metal came from though.....   :-/

Always hard from a distance, but my guess is that a) the crank has turned and 2) the slots should line up and 3) that bit of metal is the key that needs to go in the slots.

If you lined the slots up and put the outer pulley back on, would that show you where the timing was?

Right, looking into the small pulley with the teeth on... I can see where a bit of metal has broken off. I wonder if this is what holds it on the slot on the crank...

[hotel21]

With no actual experience of this engine but a number of others, that would be a fair assumption.

A machined peg internally on the pulley to mate with a cut slot on the crankshaft or vice versa.  That would also explain why the keys are not shown as a part - there are none seperately.  Would mean a replavement bottom toothed pulley.  Ron McB is breaking an engine, is he not??

The metal has broken off? Woodruff keys use a seperate 'key', not one attached to one part.  Would this then line up? If so, you need a new pulley....

I think this is the way it's going... I also have a spare engine, with Gbox off, so flywheel locking wouldn't be too hard. Thing is, it's 75 miles from me, and car

I may have to ask FIN about having his...if he still has that engine. I doubt I'll get it for tomorrow, the next day may do at a push  

[hotel21]

Must have had too much fresh air today....

There HAS to be a means to correctly locate the pulley on the crank.  Thats all its for, to locate it.  All thrust/torsion is taken up by the grip of the taper as induced by the chuffin tight bolt.

New pully required and a clean out of the broken bit in the crank taper.......

How did you hold it all together when releasing the bolt?  Undue twisting on the pulley causing it to shear the locator peg or was it fubar'ed to start with?

Agreed.  Ive not seen a crank pulley with integral key built in but I guess its possible... Unusual though.

Sadly i reckon it sheared whilst undoing the kin tight bolt :-/ That 250++ is kin tight

Locked flywheel

[Kevin Wood]

My money is on it being either a woodruf key or a lug that has broken off the pulley.

The slot machined in the end of the crankshaft - is it a constant "depth" throughout its' length from front to back or a kind of "half moon" profile?

If it's a constant depth I'd wager there was a lug on the pulley and it broke off. If not, was the bit of metal that came off a half moon profile on one edge and straight on the other?

Some pics of the two ends and the bit of metal that came out would be good.

Since the timing reference for the crank is on the pulley there will be something to positively locate it at the correct position relative to the crank.

Sounds like the only way to be sure is for Ronnie to take his pulley off and see how it compares.

Ok, so you now know why we said to fabricate a tool to lock the crank....

If you lock the flywheel you bugger the woodruff key like you have done and normaly the pulley with it....lets hope the crank is not damaged (Can somebody look to see if the woodruff key is seperate to the crank on EPC as it might be a machined part of the crank in which case your in big trouble).


You should also have set the crank to 60 deg before tdc and popped the belt off and then let the cams relax.....much safer.
