5. Refit the transmission oil feed pipe, ensuring the
upper end of the pipe is fully seated in the
transmission spray bar.

As a precaution, before fitting the oil pump to the
crankcase ensure the pump internal surfaces have been
'wetted' with clean engine oil. The pump may fail to
pick-up oil from the sump if the surfaces have not been
'wetted'. This will cause the engine to run without
engine oil pressure and will lead to severe engine
damage.
