Disassembly and Assembly
NBS001PF
DISASSEMBLY
1.
Remove oil pump cover.
2.
Remove oil pump inner rotor and oil pump outer rotor from oil pump body.
3.
After removing regulator plug, remove regulator spring and regulator valve.
INSPECTION AFTER DISASSEMBLY
Oil Pump Clearance
●
Measure clearance with a feeler gauge.
Clearance between oil pump outer rotor and oil pump body
(position 1)
Tip clearance between oil pump inner rotor and oil pump outer
rotor (position 2)
●
Measure clearance with a feeler gauge and a straightedge.
Side clearance between oil pump inner rotor and oil pump body
(position 3)
Side clearance between oil pump outer rotor and oil pump body
(position4)
●
Calculate the clearance between oil pump inner rotor and oil
pump body as follows:
–
Measure the outer diameter of protruded portion of oil pump
inner rotor with a micrometer (Position 5)
–
Measure the inner diameter of oil pump body with an inside
micrometer (Position 6)
•
(Clearance) = (Oil pump body inner diameter) – (Oil pump inner
rotor outer diameter)
●
If out of the standard, replace oil pump assembly.

OIL PUMP
Regulator Valve Clearance
(Clearance) = “D1” (Valve hole diameter) – “D2” (Regulator valve
outer diameter)
●
If out of the standard, replace oil pump assembly.
CAUTION:
●
Coat regulator valve with engine oil.
●
Make sure that it falls smoothly into the regulator valve hole
by its own weight.
ASSEMBLY
Note the following, and assembly is in the reverse order of disas-
sembly.
●
Install oil pump inner rotor and oil pump outer rotor with the
punched marks on the oil pump cover side.
Standard
: 0.040 - 0.097 mm (0.0016 - 0.0038 in)
