• The filter elements use elements
made of filter paper.

4.1 Engine oil bypass alarm switch

• If the full-flow oil filter elements clog
up, this will restrict the flow of engine
oil, causing various parts of the engine
to seize. To prevent this, the engine oil
bypass alarm switch is installed.
• If the full-flow oil filter clogs up, the en-
gine oil bypass alarm switch trips in
such a way as to direct the engine oil
straight on to the oil cooler, bypassing
the filter elements. When the engine
oil bypass alarm switch trips, the rele-
vant warning lamp illuminates to alert
the operator to the clogged full-flow oil
filter elements.
