5A-120 Automatic Transmission/Transaxle: 

Oil Pump Inspection

S6JB0B5106034

• Measure inside diameter of oil pump body bushing.

If inside diameter exceeds limit, replace oil pump 
body.

Oil pump body bushing inside diameter limit
38.188 mm (1.504 in.)

• Measure inside diameter of stator shaft assembly 

bushing.
If inside diameter exceeds limit, replace stator shaft 
assembly.

Stator shaft assembly bushing inside diameter 
limit
Torque converter side: 21.577 mm (0.850 in.)
Output shaft side: 32.08 mm (1.263 in.)

• Check oil pump body clearance of driven gear.

Push driven gear (1) to one side of oil pump body (2).
Using a feeler gauge, measure clearance between 
driven gear (1) and oil pump body (2).
If clearance exceeds standard value, replace oil pump 
assembly.

Clearance between driven gear and oil pump body
Standard: 0.10 – 0.17 mm (0.004 – 0.007 in.)

• Check tip clearance of driven gear.

Measure radial clearance between driven and drive 
gears tooth tip.
If clearance exceeds standard value, replace oil pump 
assembly.

Tip clearance between driven gear and drive gear
Standard: 0.07 – 0.15 mm (0.003 – 0.006 in.)

• Check side clearance of both gears.

Using a straightedge (1) and a feeler gauge, measure 
side clearance between gears and oil pump body.
If clearance exceeds standard value, replace oil pump 
assembly.

Side clearance between gears and oil pump body
Standard: 0.02 – 0.05 mm (0.0008 – 0.002 in.)
