Topic: Removing cylinder head with hd studs and gasketsinch

[Sweep]

I hit it from all sides with a mallet and even tried to budge it with a few shots of a drift, nothing.  Any ideas on getting a well torqued cylinder head off?

 I'll start with the usual "are ya sure you've got all the nuts & bolts removed?". It's been a few months but if memory serves there's the 12 torque nuts, then the 4 bolts under the towers, the 4 nuts in the spark plug recesses, the 2 external bolts(fore and aft), and the removal of the cam chain tensioner.

  If this is a recent engine that you're tearing back into then it should come loose fairly easily regardless of what you torqued it to. Once certain that every nut and bolt is removed I'll grab the head by the fins and try to twist it back and forth before giving each side an upward rap with the palm of the hand.

   I've sometimes had to use a wooden drift to pop the cylinder block loose, but never had to use one on the cylinder head.

There is usually a cutout in the gasket at each end, so you can get a screwdriver in & hit it with a mallet. Always comes off.

 A very smooth screwdriver with no burrs I would hope (shudder)

I removed all of those nuts and the allen fastener.  I'll just manhandle it tomorrow.

propane torch the side of the cylinder evenly on both sides.then hit with a rubber snap on hammer with sand inside. should come off with no prying.

Good idea, I'll try it.

Then what else are they for? This is used on quite a few head gaskets.

At least put a piece of 1/4 wood under the head before you whack it.. and maybe dont GLUE your engine together..

i think there is bolts hidden under the round oil black seals?

I got all the bolts off and the head off with a strategically placed drift.  The Gasketsinch came recommended and works well but is pretty sticky for sure.

G'Day David, have a look at your workshop manual mate, it says specifically "not" to use screwdrivers, chisels etc, for fear of damaging the gasket mating surfaces. Tempting I know, but not recommended. Cheers, Terry.

Oh, I know. But being very careful, I have always managed. But if there is a glue, I would think twice. I thought a hammer was the first tool in a tool box?

I had a Harley sportster years ago (great bike too, you won't hear any anti-Harley bullshiite from me) and my favourite tool was my hammer and my impact driver! Come to think of it, nothing much has changed, ha ha!
