Rear Drive and Dual Wheels With Heavy Duty Hubs—Adjusting and Tightening

RXA0087611-UN-13MAR06

Drive Wheel Shown

A - Pinion Gear

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.

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

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

   NOTE: Dual hub does not have pinion gear.

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

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

   Item	Measurement	Specification
   Sleeve Bolts	Initial Torque	204 N˙m (150 lb-ft)
   Sleeve Bolts	Intermediate Torque	410 N˙m (300 lb-ft)

5. IMPORTANT: Some sleeve bolts may loosen as sleeve is tightened. Repeat star shaped torquing pattern until ALL sleeve bolts maintain the proper torque. Failure to follow procedure could result in damage to equipment and may result in personal injury.

   Drive tractor a minimum of 100 meters (110 yd) and using previously described method tighten to final torque.

   Item	Measurement	Specification
   Sleeve Bolts	Final Torque	600 N˙m (445 lb-ft)

6. Torque bolts after working 3 HOURS, 10 HOURS, and DAILY during the first week of operation.
