LUBRICATION SYSTEM
DESCRIPTION
Briggs & Stratton Daihatsu gasoline and diesel engines use a full pressure lubrication system with an oil filter.
The gear driven oil pump draws oil from a screened oil pickup in the oil pan and pumps the oil through the oil filter.
The filtered oil flows through oil galleries in the cylinder block and is distributed to the main bearings, connecting rod
bearings, camshaft bearings and rocker arm shaft.
A pressure relief valve limits the maximum oil pressure in the system.
CHANGE OIL
Change oil and filter after first 50 hours of operation.
Thereafter, change oil every 100 hours of operation.
Change oil filter every 200 hours of operation.
Change oil and filter more often if engine is operated
in dusty or dirty conditions or if engine is operated
under heavy loads or high ambient air temperatures.
Remove oil drain plug and drain oil while engine is still
warm, Fig. 1. Check oil drain plug gasket and replace if
necessary. Install and torque drain plug to 24.8 Nm
(220 in. lbs.).
