Oil Filter - Mitsubishi 6M60-TL Service Manual

4. Oil filter
• This oil filter is a spin-on paper-filter
type that incorporates both a full-flow
filter and a bypass filter.
4.1 Engine oil bypass alarm switch
• If the oil filter elements clog up, this
will restrict the flow of engine oil, caus-
ing the engine to seize. To prevent this,
the oil filter is provided with the engine
oil bypass alarm switch.
• If the oil filter clogs up, the engine oil
bypass alarm switch trips in such a
way as to direct the engine oil straight
on to the oil cooler, bypassing the full-
flow and bypass filter elements. When
the switch trips, the relevant warning
lamp illuminates to alert the operator
to the clogged oil filter.
