Removal & Installation
The lubrication system is a full-flow filtration, pressure feed type. The Balance Shaft Module (BSM) is mounted below the ladder frame and chain driven by the crankshaft. The BSM consists of a non-serviceable pump, oil pressure relief valve, and a non-serviceable balance assembly. If there is a problem with the BSM, it must be replaced.
