Wipe the components with a clean piece of lint free cloth before the fluid dries.Use CoMat 02-099 LINT-FREE CLOTH and CoMat 01-002 SOLVENT, DELETED. to clean the interfaces of these components: bracket General Services Harness (71-51-43, 05-990), low pressure oil (LPO) switch LOW OIL PRESSURE SWITCH (79-34-15, 01-010), bolts LOW OIL PRESSURE SWITCH (79-34-15, 01-020), electrical connectors and oil tubes.
SUBTASK 72-00-32-110-051 Clean the Parts
Refer to Figure.
Hold the LPO switch LOW OIL PRESSURE SWITCH (79-34-15, 01-010) on the bracket General Services Harness (71-51-43, 05-990), in the position noted on removal. Attach the switch LOW OIL PRESSURE SWITCH (79-34-15, 01-010) to the bracket General Services Harness (71-51-43, 05-990) with the bolts LOW OIL PRESSURE SWITCH (79-34-15, 01-020). Torque the bolts LOW OIL PRESSURE SWITCH (79-34-15, 01-020) to 100 lbf.in (11.3 Nm).
Connect the oil tubes to the LPO switch LOW OIL PRESSURE SWITCH (79-34-15, 01-010). Hold the unions LOW OIL PRESSURE SWITCH (79-34-15, 01-009) with an applicable wrench and torque the tube nuts to between 135 and 145 lbf.in (15.3 and 16.4 Nm).
