Maintenance Instructions LUBRICATION59Mower Deck Gearboxes(shown with gearbox cover removed for clarity)2. Clean the area around the individual gearboxcover plates to prevent contaminants from en-tering the gearcase.3. Remove the screws securing the cover plateson the blade drive gearboxes.4. Check the level of lubricant in the gearboxes. Ifthe lubricant is low, add SAE E.P. (ExtremePressure) 80W-90 (API GL-5) gear lube untilthe oil level is up to (submerges) the horizontalshaft in the gearbox (shaft parallel to coverplate).NOTE: In case the gearboxes are completelydrained of oil, approximately 5 fl. oz. (15 cl) of oilper gearbox is required to refill the gear driveassembly.NOTE: Since the gearboxes are connected asa unit by connector tubes, it is necessary to addoil slowly. Allow a few minutes after adding oilfor the oil to flow throughout the assembly andthe oil level to stabilize before reassembly.IMPORTANT: DO NOT overfill the deck gear-boxes. The gearbox assembly is not vented,and overfilling with oil will cause excessive pres-sure and result in oil leaks.5. Check condition of the cover gasket and replaceif worn or damaged. Reinstall gearbox coverplates; torque screws to 24 in-lb (2.7 N·m).DSD52 or DSD62 Mower Deck LubricationThere are several special lubrication requirementsfor the DSD52 or DSD62 mower deck in addition tothe requirements detailed in the Chassis and DeckLubrication illustration. Lubricate the locationsshown in the Blade Spindle Lubrication and Gear-box, Dolly Wheel, and U-Joint Lubrication photosand check and maintain oil in the belt drive gearbox.1. Lubricate the blade spindles every 25 hourswith two (2) shots of SAE general purpose lithi-um or molybdenum base grease.Blade Spindle Lubrication2. Check the oil level in the belt drive gearbox ev-ery 100 hours (or sooner if a visible oil leak hasdeveloped). With the deck in the normal oper-ating position, remove the level plug in the sideof the gearcase. Add SAE E.P. (Extreme Pres-sure) 80W-90 (API GL-5) gear lube to maintainthe oil level to the plug. If the oil level is low,check the gearbox for any indication of an oilleak. If an oil leak is noted, the gearbox willneed to be removed and rebuilt.3. Lubricate the dolly wheel pivot every 25 hourswith general purpose grease.4. Lubricate the U-Joint in the drive shaft every8 hours with SAE general purpose lithium ormolybdenum base grease.Blade DriveGearboxesTeeGearboxBladeSpindles
