4. Unscrew the nut with the plugged hole, remove the washer; unscrew the oil pump mounting bolt and remove it together with the washer.
5. Remove the oil pump from inside the cylinder block.
Installing an oil pump
1. Install the oil pump inside the engine cylinder block so that the conical hole in its housing is opposite the threaded hole for the mounting bolt.
2. Install the copper washer, tighten the oil pump mounting bolt and the plugged nut together with the washer.
3. Measure the width of the gap between the surfaces of the threaded plug and the engine cylinder block.
4. Install a 0.05–0.10 mm thick washer to ensure adequate working clearance.
5. Install the oil pan.
6. Perform the remaining steps in the reverse order of the process of removing the oil pump.
