The cylinder jacket is a single-piece iron casting, its height determined
by the space required for the scavenge air receiver. Access to the
piston underside is possible from the receiver side of the engine to
allow maintenance of the piston rod gland and piston ring inspection.
On the fuel side, one door per cylinder can be opened for inspection
and to support in-engine work from outside. The tilting-pad thrust
bearing is integrated in the bedplate, the pads arranged to ensure a
safe and uniform load distribution. The thrust bearing girder consists
of only two steel cast pieces, omitting welding seams in critical corners;
the girder is clearly stiffer than in previous designs
