Timing (page 2 of 2)

To improve cooling of the pistons on the right main bearing spray jets have been fitted on the front and centre main journals.

Through two transversal grooves and suitable branches machined in the crankcase and cylinder heads the oil reaches the camshaft bearings and allows the hydraulic tappets to work.

The lubrication oil of the main and rod journals falls back into the sump.

1. Oil pump with pressure limiting valve
2. Oil sump
3. Oil filter with by-pass valve
4. Hydraulic tappet
5. Low oil pressure warning light sensor
6. Spray jets

The cylinder head lubricating oil collected in the tray of the camshaft bearings returns to the sump through two special outside connection hoses.

The lubrication system is fitted with an oil vapour recirculation system which recovers the vapours from the sump.

A warning light on the instrument cluster connected to a sensor in the rear engine cover indicates low engine oil pressure.
