LUBRICATION SYSTEM
Used engine oil may cause skin cancer if repeatedly left
in
contact with the skin for prolonged periods. Although this
is
unlikely
unless you handle used oil on a daily basis, it
is
still advisable to thoroughly wash your hands with soap and water
as
soon as
possible after handling used oil.
• The oil pump can
be
serviced with the engine installed
in
the frame.
• The service procedures
in
this section must
be
performed with the engine oil drained.
• When removing and installing the oil pump, use care not to allow dust or dirt to enter the engine.
• If any portion of the
oil
pump is worn beyond the specified service limits, replace the oil pump as an assembly.
• After the oil pump has been installed, check that there are
no
oil leaks.
