Specification; Triumphengine Oil - Triumph TIGER Service Manual

L r.ra
Oil is collected from the sump and is drawn through a
mesh strainer into the oil pump rotor. The oil pump is
fitted with a single pumping rotor which supplies
pressurised oil to the lubrication circuit and the oil cooler.
Pressurised oil is delivered to the outside rim of the oil
filter near to where the oil pressure relief valve is fitted.
The relief valve is set to open at 75 Ib/in2 and when
returns hi h ressure it dir
o ect to the sum .

Filtered oil is then fed into the lower crankcase galle
from here is distributed around the engine:
1. Some oil is sent directly to the cylinder head via a
drilling in the upper crankcase and an external link
pipe. A low oil pressure warning light switch is
located at the crankcase end of the link pipe. Oil that
arrives at the cylinder head is fed to both cams via a
galle ry
in the cylinder head casting that delivers oil
directly to the sprocket end cam bearings. Oil is then
fed through the hollow camshafts to the other
camshaft bearings, the tappet buckets and the
valves.
2.
The remaining oil is sent directly to the remote oil
cooler (mounted beneath the radiator). Cooled oil is
returned to the main galle
crankshaft. Here it is delivered to the crankshaft main
bearings and, via drillings in the
big end bea
ri ngs.
Spray jets located in the upper crankcase, behind the
main bearing shells, lubricate the pistons and connecting
rod small ends. These jets are fed oil from the crankshaft
oil feed.
Oil is fed to the gearbox via internal oil pipes and drillings
that supply oil directly to the end of each shaft. Oil is
circulated along the gearbox shafts to exit holes that feed
directly to the bearings, gears and selectors.
On the Tiger, oil is also fed to the alternator cover to aid
cooling of the alternator. The oil is taken from the
crankshaft oil feed and directed to the cover via drillings in
the upper crankcase and through a small hole in the cover
gasket.
