In this part of the Rover sd1 website we go deeper into the technical aspects of the Rover 6  cilinder engines. Both 2300 and 2600 engines share the same design based on a 6 cylinder inline  engine. The historical background of the engine can be read elsewhere on this website, here  mainly technical information on how to overhaul the engine, ignition timing, carburettor settings  and many other information. 

Description

The 2300/2600 engine is a water cooled unit having cast cylinder block with inline block  bores. The cylinder head is of cast aluminium alloy construction, crossflow ports, modified  hemispherical combustion chambers and valve seat inserts. Valves in the cylinder head  are set at 40° - the optimum angle for the combustion chamber. The inlet valve is  operated directly by the camshaft via an inverted bucket tappet. The exhaust valve is  activated by a cast-iron rocker from the same cam. Both valves have chromium-plated  sterns for durability. The camshaft is of cast iron and is fitted in the cyl inder head, driven by a toothed belt  from the crankshaft pulley and supported by seven bearings in a separate aluminium alloy  carrier. The pistons are of aluminum alloy with a solid skirt and have two compression  rings and a scraper ring assembly, they are connected to the connecting rods with fully  floating gudgeon pins. The crankshaft is a steel ferging with integral balance weights and  fcur main bearings. The bearings are steel backed leaded bronze with lead indium  overlay. A torsional vibration damper is incorporated in the pulley wheel on the  crankshaft nose.
