How to remove cylinder head location sleeves

<< < (2/2)

Sesman:
I did the same. I didn’t notice until I tightened the head down. The relocated with an almighty cracking noise. A real heart stopper.

Ah, OK, so they need to come out then. Why not try just heating the barrels in the oven, the liners should drop down so they are level. They would have been level when they left the factory so unless someone has been playing around in the past, they should be level now.

Thanks Nurse Julie!
Lightbulb moment!
I've already heated the barrels in the oven once to cure the Simonez paint so they must have moved then! I'll bake them again tonight, but this time I'll support the base so the sleeves are clear and can slip back down.

If they don't drop down on their own after heating, give them a whack with a plastic mallet.

Recently had the same problem, but shown how to remove the location sleeves using flush side wire cutter. If necessary shove a drill bit down to hold its shape, but in my case all came out simply levering the sleeves up with the wire cutter.

Minor damage for sure to the sleeves, but easily dressed out…
