Procedure

1. Open the oil drain valve and drain the crank- case oil.
2. Remove the filter by turning it counterclockwise with a filter wrench.
3. Loosen the two capscrews that secure the adapter to the engine block and remove the adapter and gasket. The low oil pressure cutoff switch is installed in a threaded hole in the filter adapter. See Figure 17. To reassemble the oil filter and adapter, perform these steps in reverse order. Install a new adapter gasket so that the two small oil holes are aligned with the oil holes in the block. This gasket should be installed dry. Coat the threads of each caps- crew with non-hardening sealer and torque to spec- ifications. Oil Base Drain the oil before removing the oil base. Always use a new gasket when replacing the oil base.
