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.
