1) Check body clearance of driven gear (1).
Push driven gear (2) to one side of oil pump body
(3). Using a feeler gauge, measure clearance
between driven gear (2) and body (3). If clearance
exceeds standard value, replace gear.
Clearance between driven gear and body
Standard: 0.075 – 0.15 mm (0.00295 – 0.0059 in.)
2) Check tip clearance of both drive and driven gears.
Measure radial clearance between gear tooth tip and
crescent (1). If clearance exceeds standard value,
replace gears.
Clearance between driven gear and crescent
Standard: 0.010 – 0.248 mm (0.0004 – 0.0098 in.)
Clearance between drive gear and crescent
Standard: 0.013 – 0.292 mm (0.0005 – 0.0115 in.)
3) Check side clearance of both gears.
Using a straightedge (1) and a feeler gauge,
measure side clearance between gears and pump
body.
If clearance exceeds standard value, replace gears.
Side clearance between gears and oil pump body
Standard: 0.02 – 0.05 mm (0.0008 – 0.0019 in.)
Drive gear and driven gear have some kinds of
thickness as listed.
Drive gear and driven gear thickness
If side clearance of the thickest gear is out of
specification, replace oil pump body or assembly
and stator shaft subassembly.
