Disassembly
Install the oil pump body in an arbor press with the cover mounting surface of the body facing down.
Use a mandrel to push the driven shaft from the lubricating oil pump body.
Inspection
Visually inspect the driven shaft bore in the lubricating oil pump body for damage.
Measure the inside diameter of the driven shaft bore.
NOTE: If the shaft bore diameter is not within specifications, the pump body must be replaced.
Measure the driven shaft outside diameter in the press fit area.
Assembly
Use gear and spacer mandrel, Part No. ST-1157, to install the driven shaft into the oil pump body as follows:
1. Lubricate the large outside diameter of the driven shaft with clean 15W-40 oil.
2. Install the large outside diameter of the driven shaft into the bore in the oil pump body.
3. Use an arbor press and the gear and spacer mandrel to push the shaft into the bore.
4. Measure the amount of shaft protrusion above the oil pump cover mounting surface.
