Rear Drive Wheel - Adjusting and Tightening

causym 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.

1. Raise the tractor on level ground with rack upward on the axle.

2. Loosen (without removing) sleeve bolts (1-10) just enough to move wheel.

IMPORTANT: Do not loosen or remove the two allen head screws. Doing so could result in wheel jamming or damage.

Failure to follow proper torquing sequence may result in damage to wheel sleeves.

3. Turn pinion gear (A) to move wheel to desired position.

NOTE: Dual hub does not have pinion gear.

causym CAUTION: Avoid the possibility of personal injury. Failure to follow torquing sequence and procedure will result in damage to equipment and may result in personal injury. Wheel bolts are critical and require repeated torquing.

4. Tighten sleeve bolts in numerical order (1-10) to initial torque and then in numerical order (1-10) tighten to intermediate torque.

Specification

Sleeve Bolts -Initial Torque 204 N·m (150 lb-ft)
