OIL FILTER AND OIL PRESSURE SENSOR
Disassembly:
——To demount the oil filter by rotating the filter
counterclockwise.
——To remove the oil pressure sensor.
Assembly:
——To spread engine lubrication oil onto the oil filter
gasket and screw it up to the fitting to 12-17N.m.,
or screw the oil filter manually and screw more
3/4-1 round when the rudder gasket reaches the
cylinder.
