  • Page 47: Section 8: Lubrication System

    SECTION 8: LUBRICATION SYSTEM DESCRIPTION The Generac GTH/GTV-760/990 OHVI V-twins use a full pressure lubri- cation system with an oil filter. The gerotor type oil pump draws oil from a screened oil pickup in the sump and pumps oil through the oil filter. The filtered oil flows through an oil gallery in the sump and is distributed to the main bearings, connecting rod bearings and camshaft bearings.
  • Page 48 SECTION 8: LUBRICATION SYSTEM CHANGING THE ENGINE OIL AND FILTER RECOMMENDED OIL TYPE: Using the proper type and weight of oil in the crankcase is extremely important. Check the oil before each use and change the oil regularly (see Figures 1-1 through 1-5). Failure to use the correct oil, or using dirty oil, can cause premature engine wear and failure.
  • Page 49 SECTION 8: LUBRICATION SYSTEM OIL COOLER All GTH/GTV-760/990 V-Twin engines are equipped with an oil cooler, PUMP BODY which is mounted on the blower housing. Forced air from the flywheel fan flows through the oil cooler fins dissipating heat from the engine oil (see Figure 8-5) .
