Maintenance Instructions LUBRICATION314. Before removing the oil filter, clean the areaaround the filter to keep dirt and debris out ofthe engine.5. Remove the old oil filter and wipe off the filtermounting surface on the engine.6. Apply a thin coating of clean oil to the rubbergasket on the replacement oil filter.IMPORTANT: Use ONLY oil filters from the en-gine manufacturer (Kawasaki 49065-2078). Af-termarket oil filters may not seal properly and/ormay not have the correct pressure relief valvefor proper lubrication.7. Install the new oil filter on the engine. Turn thefilter clockwise until the rubber gasket contactsthe sealing surface, then tighten an additional1/2 turn.8. Close drain valve.9. Fill the crankcase with new, clean oil. Use onlycrankcase lubricants recommended by the en-gine manufacturer. Refer to Specifications inthis manual or the engine owner’s manual. Usethe recommended oil viscosity for the expectedambient temperature. Oil with the correct vis-cosity will aid starting in cold weather and as-sure proper lubrication in hot weather. Fill upto, but not above, the upper mark on the dip-stick. Crankcase capacity is 1.6 quarts (1.5 li-ters) plus 0.2 quart (0.2 liters) for the new oilfilter.IMPORTANT: Check the dipstick reading be-fore adding the last 1/2 pint of oil and fill only tothe upper mark. DO NOT overfill the crankcase(oil above upper mark) as this CAN result inengine overheating, loss of power, and possi-ble engine damage.10. Start the engine and check for oil leaks aroundthe oil filter. Stop the engine, recheck the oil lev-el, and add oil if necessary. (When the engineis first operated with a new oil filter, the oil leveldrops slightly as the filter is filled with oil.)Grease Fitting and Oil Point LubricationLubricate the grease fittings and oil points after ev-ery 25 hours of operation. Lubricate more oftenwhen operating in dusty or dirty conditions. UseSAE general purpose lithium or molybdenum basegrease for grease fittings and light machine oil (SAE10) to lubricate oil points. Lubricate the locationsshown in the Chassis and Deck LubricationPoints illustration.NOTE: PTO universal joints (on the deck and trac-tor) require routine lubrication after every 8 hoursof running time.Mower Deck Gearbox LubricationNOTE: These instructions apply to all mowerdecks with gear-driven blades. Refer to DSD52Mower Deck Lubrication in this section for theDSD52 deck with belt-driven blades.The mower deck gearboxes (tee gearbox and bladedrive gearboxes) are connected as a unitized as-sembly, and oil flows freely between them. Thegearboxes are permanently lubricated (oil filled) andsealed requiring no scheduled lubrication. Howev-er, the gearbox oil seals should be checked every25 hours for indication of an oil leak; particularlythe lower seals on the blade drive gearboxesshould be inspected, since they operate in a dirty en-vironment. If an oil leak is noted, replace the oil sealand relubricate the gearbox assembly as follows:1. Remove gearbox cover (footrest). Deck orien-tation should be in the normal operating position.Mower Deck Gearboxes(shown with gearbox cover removed for clarity)Blade DriveGearboxesTeeGearbox
