Side Clearances
- Measure side clearance of inner and outer gears in at least four places around each outside edge. Maximum measured values should be within specified positions.
Standard clearance: 0.030 - 0.050 mm (0.0012 - 0.0020 in)
- If clearance is less than standard, select inner and outer gear as a set so that clearance is within specifications.
Inner and outer gear: Refer to " OIL PUMP ".
- If clearance is more than standard, replace whole oil pump assembly except oil pump cover.
- Measure clearance between outer gear and oil pump housing.
Standard clearance: 0.111 - 0.181 mm (0.0044 - 0.0071 in)
Allowable limit: 0.181 mm (0.0071 in)
- If not within allowable limit, replace whole oil pump assembly except oil pump cover.
