General Information


Lubricating Oil Filters

The LF9009 oil filter is used on all ISC, QSC8.3, ISL, and QSL9 with CM850 engines. This filter is a spin-on element and contains an internal venturi that provides filter bypass oil flow through a stacked disk section of the filter. Lubricating oil filters must be of the venturi style. Using a lubricating oil filter without a venturi will result in premature engine wear.
