CAUTION: Avoid personal injury. Never run the engine with transmission in gear and rear wheels off the ground. MFWD wheels could pull rear wheels off support. Disengage MFWD and put transmission in NEUTRAL to rotate axle. Never operate tractor with a loose rim, wheel, or hub.

IMPORTANT: Carefully follow procedure. Failure to do so could lead to wheel hub damage.

Tractors are equipped with 12 bolt heavy-duty wheels or 10 bolt hubs. Numbers indicating proper torquing sequence are cast into wheel hub.

Clean any paint, grease, film, rust or debris from axle shafts prior to positioning and installing wheel hubs and sleeves. DO NOT apply any lubricant to cap screws or threads.

  1. Raise the tractor on level ground and support tractor with jack stands. If equipped, rotate wheel with rack upward on the axle.

  2. Loosen (without removing) sleeve bolts just enough to move wheel. if equipped, turn pinion gear (D) to move wheel to desired position
