SEAL-WIPER 3382416 - Caterpillar

Torque Converter Inlet Relief Valve
Adjust the input rotation to 630 50 rpm.
Shift the transmission to FORWARD 1.
Use Tooling (K) to momentarily block the flow at the torque converter outlet.
The "P3" torque converter inlet pressure must be 896 82 kPa (130 12 psi).
Open the lube flow.
Record the value in Table 9.Lube Circuit Check
Shift the transmission to FORWARD 3.
Adjust the input rotation until the lube flow is 76 4 L/min (20 1 US gpm). Maintain this flow during this check.
The lubrication pressure must be 220 7 kPa (32 1 psi).
Record the value in Table 10.Contamination Control
Take an oil sample of the test bench oil supply. Oil contamination must be maximum ISO 16/13.
Record the results in Table 11.
Remove the transmission from the test bench if the test bench oil supply is within specifications.Transmission Bench Test Data Sheet
