Engine Front Cover and Oil Pump Cleaning and Inspection
Engine Front Cover Cleaning Procedure
| 1. |
Clean the engine front cover
sealing surface. |
|
Warning:
Wear safety glasses when using compressed air in
order to prevent eye injury. |
|
Caution: To
ensure proper engine lubrication, clean clogged or contaminated oil
galleries in an approved solvent and with compressed air. Failure
to clean oil galleries may cause engine damage. |
| 2. |
Clean the shown oil gallery
with solvent and compressed air. Blow compressed air from bore (2)
to bore (1). |
Engine Front Cover Visual Inspection
Inspect the engine front cover for cracks, scratches and
damage.
Oil Pump Visual Inspection and Measurement
| 1. |
Inspect the oil pump cover and
the engine front cover for flatness. |
| 2. |
Inspect the oil pump vanes,
the oil pump vane rotor, the oil pump vane rings and the oil pump
slide for localized flatting. |
| 3. |
Inspect the oil pump slide
pivot pin for firm seat. |
|
Note: Oil pump
components are installed.
|
| 4. |
Measure the oil pump axial
clearances. Use a straight edge (1) and a feeler gauge.
|
| |
4.1 |
The maximal axial clearance
between engine front cover and oil pump vane rotor should be
0.1 mm (0.004 in) . |
| |
4.2 |
The maximal axial clearance
between engine front cover and oil pump vane should be 0.09
mm (0.0035 in) . |
| |
4.3 |
The maximal axial clearance
between engine front cover and oil pump vane ring should be
0.4 mm (0.016 in) . |
| |
4.4 |
The maximal axial clearance
between engine front cover and oil pump slide should be
0.08 mm (0.0031 in) . |
| |
4.5 |
The maximal axial clearance
between engine front cover and oil pump slide seal should be
0.09 mm (0.0035 in) . |
| 5. |
Measure the oil pump radial
clearance. Use a feeler gauge (1). Measure the clearance between
oil pump vane rotor and oil pump vane (3). |
| |
The maximal clearance should be 0.05 mm (0.002
in) . |
| 6. |
Measure the clearance between
oil pump vane and oil pump slide (2). |
| |
The maximal clearance should be 0.2 mm (0.008
in) . |
