Stuck Cool Head

[JohnnyRed]

I have a Pro Design Cool head on my banshee that I cannot get off. I removed all of the nuts off the studs, disconnected the water lines and removed the lid. I removed all of the stud o-rings. Is there something I'm missing? I've never torn down a banshee and I don't want to damage anything. This bike did overheat badly when the water pump failed so that might be the problem. If so what should I do.

If you have enough room to double nut each stud, remove them, and see if maybe it's just jammed up on a stud that somehow got tweaked.

try using a rubber mallet and lightly tap the head in an upward motion. make sure to tap all the way around the head and not in just one spot.

Might also try using piece of wood/dowel to get at upward angle and tap. Try some PB Blaster or simular. Don't get to aggresive with the hammer. If there is an area overhanging cyls that is good place to tap upwards. Just keep working at it. Removing stud should be last resort , break one or strip hole you have more work. JMHO , your results may vary.

Thanks guys, I will just keep working at it. I wasn't sure if I was missing something. I am wondering if the head warped with the heat and is stuck against the studs. I might just have to try the stud removal to see if that works.

put the spark plugs back in and kick it over, if you can. that puts a lot of pressure on the domes. that should do the trick...or compressed air, which probably won't be as much as the motor turning over. if you can't do that, then try the mallet and pry in the middle, between the cylinders, just don't ding the hose nippler

^^^^^^^^^^^^^^That's a good idea.

 

Do the PD heads have copper washers? I've had the washers smash onto the stud before and not let the head come up,

i think the top half of the head shell is already off......the stud o-rings are supposed to be between the 2 half's...

x2 on the whole stud thing they tend to bend like mine it was a pain to take them off but use a rubber mallet and tap it off

Gotcha. That makes sense since he said he'd already removed the o-rings.

i attached a visegrip to a slide hammer put junk spark plugs back in, clamp visegrip to one spark plug... bing, bang, boom, works every time just go slow with light taps since its alloy and work back and forth between plugs.
