Refer to Figure.
Put the new OIL-SCAVENGE FILTER DIFFERENTIAL PRESSURE SWITCH (79-35-16, 01-007)seal ring2 off, on to the two unions OIL-SCAVENGE FILTER DIFFERENTIAL PRESSURE SWITCH (79-35-16, 01-009).
Install the unions OIL-SCAVENGE FILTER DIFFERENTIAL PRESSURE SWITCH (79-35-16, 01-009) and the seal rings OIL-SCAVENGE FILTER DIFFERENTIAL PRESSURE SWITCH (79-35-16, 01-007) to the switch OIL-SCAVENGE FILTER DIFFERENTIAL PRESSURE SWITCH (79-35-16, 01-010). Torque the unions OIL-SCAVENGE FILTER DIFFERENTIAL PRESSURE SWITCH (79-35-16, 01-009) to between 135 and 145 lbf.in (15.3 and 16.4 Nm).
Hold the SFDP OIL-SCAVENGE FILTER DIFFERENTIAL PRESSURE SWITCH (79-35-16, 01-010) on the bracket OIL-SCAVENGE FILTER DIFFERENTIAL PRESSURE SWITCH (79-35-16, 01-050) and install the bolts OIL-SCAVENGE FILTER DIFFERENTIAL PRESSURE SWITCH (79-35-16, 01-020). Torque the bolts OIL-SCAVENGE FILTER DIFFERENTIAL PRESSURE SWITCH (79-35-16, 01-020) to 40 lbfin (4.6 Nm).
Connect the oil tubes to the SFDP switch OIL-SCAVENGE FILTER DIFFERENTIAL PRESSURE SWITCH (79-35-16, 01-010). Torque the oil tube nuts to between 135 and 145 lbf.in (15.3 and 16.4 Nm).
Connect the electrical connector to the SFDP OIL-SCAVENGE FILTER DIFFERENTIAL PRESSURE SWITCH (79-35-16, 01-010).
