1. If only the oil pump needs to be repaired, place the vehicle on a lift or inspection ditch, disconnect the wires from the battery and drain the oil from the crankcase.
2. Remove the engine mudguard, unscrew the nuts securing the front engine mounts to the cross member and slightly raise the engine with a hoist.
3. Having unscrewed the mounting bolts, remove the engine crankcase and oil pump with a suction pipe.
4. Install the oil pump on the engine in the reverse order of removal.
