Problem:
Reports indicate that some 8T-9815 Pressure Switch Assemblies (low oil pressure) have been found to be loose. This can result in an oil leak. The 8T-9815 Pressure Switch Assembly is part of the attachment 7N-1896 Oil Pressure And Water Temperature Contactor Group. The illustration shows the location of the 8T-9815 Pressure Switch Assembly.
Solution:
Periodically check to be sure the 8T-9815 Pressure Switch Assembly is secure. The pressure switch should be tightened to a torque of 22.5 ± 2.5 N·m ±200 ( 22 in lb). A 9/16-inch crowfoot wrench may be required to tighten the pressure switch in the adapter.
