mounting surface. Reinstall drain plug. Torque to
14.0 N·m (125 in. lb.).
3. Place new fi lter in shallow pan with open end up. Fill
with new oil until oil reaches bottom of threads. Allow
2 minutes for oil to be absorbed by fi lter material.
4. Apply a thin fi lm of clean oil to rubber gasket on new

This engine uses a full pressure lubrication system which delivers oil under pressure to crankshaft, camshaft, and
connecting rod bearing surfaces. Other component areas are splash lubricated.
A high-effi ciency gerotor oil pump maintains high oil fl ow and oil pressure, even at low speeds and high operating
temperatures. A pressure relief valve limits maximum pressure of system. Closure plate must be removed to service
oil pickup, pressure relief valve, and oil pump.
