Re: JDMCG3's N/A H22 Build (Last Update: 01/23/2012)
question for you guys about oil pumps...
since the block i got is from a blown motor.. and was blown due to oiling problems. the guy i bought it from said the oil pan had a leak which lead to low oil levels. then he raced it with hardly any oil.
but i wanna know if there is a way i can test my oil pump to just make sure it doesnt have any problems going on with it..
so do any of you guys know of a way of testing it once its off the motor?
cause i know you can connect a oil pressure gauge to the oil pump when the motor is still in the car and running.. but idk of any way when the motor is disassembled
Its' easy to check an oil pump, it is mechanical, you simply use a feller gauge, if it is out of spec, replace it.
Testing and Inspection
HOUSING-TO-ROTOR AXIAL CLEARANCE
Check the housing-to-rotor axial clearance on the pump rotor. If the housing-to-rotor axial clearance exceeds the service limit, replace the set of inner and outer rotors and/or the pump housing.
Housing-to-Rotor Axial Clearance
Standard (New): 0.02-0.07 mm (0.001-0.003 inch)
Service Limit: 0.12 mm (0.005 inch)
HOUSING-TO-OUTER ROTOR RADIAL CLEARANCE
Check the housing-to-outer rotor radial clearance. If the housing-to-outer rotor radial clearance exceeds the service limit, replace the set of inner and outer rotors and/or the pump housing.
Housing-to-Outer Rotor Radial Clearance
Standard (New): 0.10-0.19 mm (0.004-0.007 inch)
Service Limit: 0.21 mm (0.008 inch)
INNER-TO-OUTER ROTOR RADIAL CLEARANCE
Check the inner-to-outer rotor radial clearance on the pump rotor. If the inner-to-outer rotor clearance exceeds the service limit, replace the inner and outer rotors.
Inner Rotor-to-Outer Rotor Radial Clearance
Standard (New): 0.02-0.16 mm (0.001-0.006 inch)
Service Limit: 0.20 mm (0.008 inch)
