Many thanks for that.il order one tommorow ( unless you have one !) from my local dealer

[annihilator]

I do but it's still attached to my spare engine

 Why do you need one?

The only time I've needed one was when I'd not tightened the crank pulley properly & it came out  ..... it confused me as to how the timing had gone so far out of timing ...... CIH  Cavalier & the dizzy drive gear had come out of mesh.

I need one because its on an omega v6. Extremely tight .broke 3 ends trying to remove it.the actual 1/2" socket square end ! .so just sliced its head off .never had one come loose on a cih thou.the steel pulley ones are usually undoable but the cast pulleys like on manta gte or carlton 2.2 are always tight.just rung dealer. No problem £7 ish next day.

.......never had one come loose on a cih thou......

I was rushing the job & I don't think I'd tightened it properly

What is the right way, tool and direction to remove this bolt? I would like to change the front oil seal.

Make a tool that sits against the water pump and bolts on the crank gear with the pulley bolts. Then just brute force with a breaker bar and off it comes. Easy enough

I can take a pic of my ghetto tool that I used for the crank bolt tomorrow.

That's exactly how I did mine. A bit of thought and a couple of extra holes in the tool will enable you to draw the pulley off easily.


I have a drawing with the dimensions if it would help.

Just done mine and the bolt was very tight. There was no way that it would come undone with a long extension scaffold pole and two people. Just ended up snapping three 1/2" ends clean off three different makes of tool. I found the easiest way was just to slice the bolt head off with a thin angle grinder cutting disc.maybee someone had had it off before and tightened it too much who knows.no signs of any loctite and shouldnt be !. Even with the amount of force required to re tighten(185lbs + 45 deg + 15 deg  angle tighten) i myself would not be happy putting this amount of force held against the waterpump even if i was replacing it. One crack/ split casing and the crank will move round suddenly. , !  Please no offence to anyone who does it this way but not for me

I assume there's enough shank left, to grip and remove?

[cam.in.head]

Yes the bolt is about 90mm long but only uses the first 20 or so mm to tighten onto. Bolt unscrews by hand once head is off

[polilara]

Thanks for comments, picks are welcome if found easily.
Yes, and the direction? Normal right hand?

[robson]

don't understand why a bolt will move by hand when the head has been cut off?
