Make sure that the drain pump hose reaches right down to the bottom of
the oil housing. Examine the oil.
NOTE!
Old oil should be entrusted to an oil disposal company in
accordance with local regulations.
Lay the pump down with the oil filler hole pointing upwards. Use two cranes
for this purpose. Secure the pump with wedges from both sides. Check that
the pump is firmly retained and cannot roll away.
Fill with new oil (see table on page 50). Use BP type HPL-D46 (SAE 10-20)
or equivalent oil. Always fit a new O-ring to the oil plug. Refit the oil plug
and raise the pump.
