To add to my previous. In the vid (to the left) you can see that the opening in the crankcase for the sleeve is not round. This is where the sleeve drive sits and where you access the nuts. If you look carefully in the same spot you can just make out the ball on the bottom of the sleeve. The little bell cranks you can see are what drive the sleeve.

There is a lug on the side of the sleeve, a ball type joint bolts to the underside of the lug. The ball housing has studs which protrude up through the lug on the sleeve and nuts hold it. The nuts have serated edges and are locked by a serated plate between them.

The ball fitting is used on the bottom of the sleeve to allow the sleeve to rotate and rise and fall.

Maintenance question for any sleeve valve expert:

How does one remove the sleeve valve of one cylinder of the Centaurus to gain access to a piston and rings for service? The cylinder and head are easily removable and replaceable, but without complete disassembly of the engine how does one disconnect the crank from the sleeve valve and extract the sleeve valve, leaving the piston exposed?

3270 Cubic inches, that's 53,6 liters.

This is a radial engine, not rotary.
