Timing Gears; Lubrication System - New Holland 6010 Service Manual

Engine - Engine and crankcase
Manifolds
The cross flow design aluminium intake, and cast iron exhaust manifolds are on opposite sides of the cylinder head.
This is designed to maintain balanced heat distribution within the cylinder head. The configuration of the manifolds
also ensures minimum heat transfer to the intake manifold. The intake manifold is connected through hose to air
cleaner.

Timing gears

The crankshaft timing gear is heated and press fitted on to the front of the crankshaft, to a high degree of accuracy
during manufacturing. This enables precise timing being maintained during the life of the engine. The crankshaft gear
drives the idler gear, which is attached to the front of cylinder block. The idler gear then drives the camshaft and the
injection pump via meshing helical gears
The camshaft gear is bolted to the front of the shaft and is keyed to maintain position of the gear on the camshaft.

LUBRICATION SYSTEM

Lubrication of the engine, Figure 7 & 8 is maintained by a gear type oil pump mounted in the rear of the engine block.,
forward of the flywheel on the left hand side viewing from rear side of the engine. The oil pump is driven from the rear
of the camshaft and drains oil from the engine oil sump through a tube and screen assembly
A spring loaded relief valve is integral with the oil filter and prevents over pressurization of the system. A spin on type
oil filter is mounted externally to its support housing on the left hand side of the engine. Oil flows from the filter to the
main oil gallery, which runs the length of the cylinder block, which also intersects the camshaft follower chamber.
The main gallery also supplies oil to the crankshaft main bearings, connecting rods both big and small ends and timing
gear bushes. The underside of the pistons and pins are lubricated by oil pressure jets.
Timing gears are lubricated by splashed oil from the cam follower chamber and the pressure lubricated camshaft drive
gear bushing.
