VII. SERVICE AND MAINTENANCE

Quad Pullers

Each quad puller head has four bearings equipped with grease zerks (fig. 7.35). To ensure the longest life and best performance, grease each bearing twice a day: suggested times are morning and noon.

Torque Hub ® Seal Boot

Each leg has a seal boot located between the wheel motor and Torque Hub®. Seal boot grease zerks (fig. 7.36) should be greased once every 50 hours or as needed. An over-greased 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.
