below the crankshaft center line. The engine has replaceable wet cylinder liners and individual
cylinder heads with strung-in valve seat rings and replaceable valve guides.
2.2.3. Piston / Connecting rod / Crank assembly

The connecting rods are die-forged, diagonally split and can be removed through the top of the
cylinders together with the pistons. Crankshaft and connecting rods run in steel-backed lead bronze
ready-to fit type bearings.
2.2.4. Engine timing

Camshaft, oil pump and injection pump are driven by a gear train arranged at the flywheel end.
