on engines in low duty cycle applications, for example, stand-by generating sets.
How to service your engine
Instructions are given in the remaining
sections of this chapter.
After servicing
• It is essential to ensure that nuts
and bolts are tightened to the torques
specifi ed in the Workshop Manual.
• When re-assembling an engine
lubricate all moving parts with engine oil.
• Renew nuts and bolts that have
been taken from high-stress locations.
In particular nuts and/or bolts from the
connecting rods should be renewed.
CAUtIon
Long periods of light or ‘no load’
running early in the engine’s life
may lead to cylinder bore glazing
and high oil consumption.
