ENGINE - K SERIES KV6

12-3-14 DESCRIPTION AND OPERATION

Piston Rings
Each piston is fitted with two compression rings and an oil control ring. The top compression rings are chrome-plated 
steel. The 2nd compression rings are chrome-plated cast iron. The oil control rings have stainless steel top and 
bottom rails and integral expander rings.

Crankshaft, Sump and Oil Pump Components
The crankshaft and sump components are described below:

Crankshaft
The short, stiff crankshaft is supported on four main bearings, with each pair of crankpins mutually offset by 30

°

 to 

give equal firing intervals. Cast in Spheroidal Graphite (SG) iron, the crankshaft has cold rolled fillets on all journals, 
except the outer mains, for toughness and failure resistance. End-float is controlled by thrust washer halves at the top 
and bottom of the rear main bearing.

Main Bearings
Oil grooves are provided in the upper halves of all the main bearing shells to supply oil, via drillings in the crankshaft, 
to the connecting rod big-end bearings. The lower halves of the bearing shells in the bearing ladder are plain.

Sump
The cast aluminium sump is a wet-type, sealed to the lower crankcase extension using sealant applied to the sump 
flange. The sump is fixed to the lower crankcase extension using 10 bolts. A baffle plate is fitted in the lower crankcase 
extension to minimise the effects of oil slosh.

An oil pick-up with integral strainer is located in the centre of the sump oil well, as a source for the supply of engine 
lubrication oil to the oil pump. Oil is sucked up though the end of the pick–up and strained to prevent solid matter from 
entering the oil pump.

Oil Pump
The oil pump is directly driven from the crankshaft. The oil pump housing includes the oil pressure relief valve, oil filter, 
oil pressure switch and return/supply outlets for the engine oil cooler.

Oil Filter
A full-flow, disposable canister-type oil filter is attached to the oil pump housing at the front of the engine.

Oil Cooler
A liquid cooled oil cooler keeps the engine lubrication oil cool, under heavy loads and high ambient temperatures.

The oil cooler is cooled by the engine cooling system and attached to a bracket secured to the front of the sump by 
three bolts. Oil is delivered to and from the oil cooler through hoses connected to the oil pump housing. Hoses from 
the engine cooling system are connected to two pipes on the oil cooler for the supply and return of coolant.

Oil Pressure Switch
The oil pressure switch is located in a port at the outlet side of the oil filter. It detects when a safe operating pressure 
has been reached during engine starting and initiates the illumination of a warning light in the instrument pack if the 
oil pressure drops below a given value.
