2.Clean the area around the individual gearbox cover plates to prevent contaminants from en­ tering the gearcase.

3.Remove the screws securing the cover plates on the blade drive gearboxes.

4.Check the level of lubricant in the gearboxes. If the lubricant is low, add SAE E.P. (Extreme Pressure) 80W-90 (API GL-5) gear lube until the oil level is up to (submerges) the horizontal shaft in the gearbox (shaft parallel to cover plate).

NOTE: In case the gearboxes are completely drained of oil, approximately 5 fl. oz. (15 cl) of oil per gearbox is required to refill the gear drive assembly.

NOTE: Since the gearboxes are connected as a unit by connector tubes, it is necessary to add oil slowly. Allow a few minutes after adding oil for the oil to flow throughout the assembly and the 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 replace if worn or damaged. Reinstall gearbox cover plates; torque screws to 24 lb·in. (3 N·m).

DS52 or DS62 Mower Deck Lubrication

There are several special lubrication requirements for the DS52 or DS62 mower deck in addition to the require­ments detailed in the Chassis and Deck Lubrication­ illustration. Lubricate the locations shown in the Gearbox, Dolly­ Wheel, and U-Joint Lubrication photo and check and maintain oil in the belt drive gearbox.

1.Check the oil level in the belt drive gearbox ev­ ery 100 hours (or sooner if a visible oil leak has developed). With the deck in the normal oper­ ating position, remove the level plug in the side of the gearcase. Add SAE E.P. (Extreme Pres­ sure) 80W-90 (API GL-5) gear lube to maintain the oil level to the plug. If the oil level is low, check the gearbox­ for any indication of an oil leak. If an oil leak is noted, the gearbox will need to be removed and rebuilt.

2.Lubricate the dolly wheel pivot every 25 hours with general purpose grease.

3.Lubricate the U-Joint in the drive shaft every 8 hours with SAE general purpose lithium or molybdenum base grease.
