Oil Filter Assembly
The oil filter assembly, with a replaceable element, is mounted remote to the engine. It is attached to a mounting
bracket fitted to the left of the radiator and the filter is mounted on two rubber mounts to reduce vibration.
Two re-inforced flexible hoses, feed and return, are fitted between the filter assembly and the crankcase mounted
adaptor plate. The hose connections are of the push fit type and sealed with an “O” ring seal. The filter hose
connections are secured by a locking plate bolted to the filter body. The sump hose connections are secured to the
crankcase adaptor with a securing bracket. This bracket is attached with a stud and nut.
A by-pass valve is located internally in the lower end of the filter body. This allows the oil to by-pass the filter if the
filter element becomes blocked
A second valve is screwed into the filter body. It is connected to a rigid pipe on the sump by a flexible hose secured
by two hose clips. The rigid pipe has a banjo fitting on the sump connection. When the filter is removed, the valve
opens allowing oil in the housing to drain to the sump.
The oil pressure switch screws into the base of the filter body.
