gs500 barrels stuck!!!

[mark herbert]

Hi guys hope you can prove i'm not a total numpty!!
I have a gs500 motor i'm trying to strip for a 450 hybrid project, I've got the head off etc, but can't get the barrels off the cases,( pistons are free moving) are there any hidden bolts etc that hold the barrels in place that I've missed? or are they just stuck on with years of crap!!

cheers Mark.

Gasket is holding it in place.

Best to pry very carefully, away from any fins, or they will break off.

+1.


It should be just a 0.010 metal gasket holding it down unless someone coated it with gasket sealer.

In that case juts keep trying.

I used a soft blow hammer on the center of the front of the cylinder where there were no fins.


Expect to find that there will be rust and grit that will fall into the case when you get it free.

The middle 4 studs are open to the elements and always fill up with crap that ends up down in the case.
