VII. SERVICE AND MAINTENANCE

LUBRICATION CONTINUED

Quad Pullers

Each quad puller head has four bearings equipped with grease zerks (fig. 7.36). To ensure the longest life and best performance, grease each bearing twice a day: suggested times are morning and noon.

Male Row Choppers

Each male row chopper has two bearings equipped with grease zerks (fig. 7.37). Grease each bearing once a day.

Torque Hub ® Seal Boot

Each leg has a seal boot located between the wheel motor and Torque Hub®. Seal boot grease zerks (fig. 7.38A & 7.38B) should be greased once every 75 hours or as needed. An overgreased seal boot will leak some grease out around the seal and when heated may cause the appearance of a failed wheel motor leaking hydraulic fluid. Wipe off any excess grease after servicing.
