OIL PUMP OVERHAUL



These procedures are performed with the oil pump removed from the engine.

Except 1829cc Engine
  1. Check the rotor radial clearance on both the inner and outer rotors. Clearance is 0.05-0.15mm.
  2.  
  3. Using a wire gauge, check body-to-rotor clearance of both rotors. Clearance is 0.10-0.18mm new, with 0.20mm as the service limit.
  4.  
  5. Using a feeler gauge and a straight edge, check the rotor end-play between the rotor face and the gasket surface, gasket installed. End-play should be 0.025-0.100mm new, with a service limit of 0.152mm.
  6.  
  7. If the rotors should require replacement, inner and outer rotors on both upper and lower halves are installed with the punch marks aligned adjacent to one another.
  8.  
  9. To install, reverse the removal procedures.
  10.  

1829cc Engine
  1. Check the rotor radial clearance on both the inner and outer rotors. Clearance is 0.152-0.203mm.
  2.  
  3. Using a feeler gauge, check body-to-rotor clearance of both rotors. Clearance is 0.10-0.18mm new, with 0.200mm as the service limit.
  4.  
  5. Using a feeler gauge and a straight edge, check the rotor end-play between the rotor face and the gasket surface, gasket installed. End play should be 0.025-0.100mm new, with a service limit of 0.152mm.
  6.  
  7. If the rotors should require replacement, inner and outer rotors on both upper and lower halves are installed with the punch marks aligned adjacent to one another.
  8.  
  9. Using petroleum jelly, pack the pump cavity and reassemble it.
  10.  
  11. To install, reverse the removal procedures.
