Measuring outer rotor-to-inner rotor clearance(c) Using a straight edge and a thickness gauge, measure the clearance between the rotors and pump cover. If the measurement exceeds the limit, replace either the rotors or the pump body.
Unit: mm (in.)
Measuring clearance between rotors and pump over(2) Oil Pressure Switch(a) Connect a tester (set to the ohm range) between the terminal and body of the oil pressure switch. There should be continuity. If there is no continuity, the switch is faulty and should be replaced.
Inspecting oil pressure switch(b) Insert a thin rod into the oil hole in the switch body. When the rod is then pushed in gently, there should be no continuity between the switch body and terminal. If there is continuity, the switch is faulty and should be replaced.(c) Apply an air pressure of 49 kPa {0.5 kgf/cm2} (7.2 psi) to the switch through the oil hole. If there is no continuity, the switch is normal. Simultaneously, check for air leakage. Any air leakage means that the diaphragm is broken and, therefore, the switch should be replaced.

Points to note during reassembly of oil pump KEY POINTS FOR REASSEMBLY Oil Pressure Switch(a) Install the switch using the Oil Pressure Switch Socket Wrench (MD998054).(b) Before installation, apply sealant to the threads of the switch. (Use either Hermeseal H1 or Threebond 1104).
(a) Avoid applying sealant excessively to prevent it from reaching the end of the threads.(b) Never tighten the switch to a torque exceeding specification.
