Installing 76x50.00B32 Wheel and Tire Assembly

IMPORTANT: Wheel, rim and components used with 76x50.00B32 tire are not warranted by John Deere. For replacement parts call Southern Wheel and Rim at 1-800-438-8856 to find nearest dealer location.

CAUTION: Avoid personal injury. Never run the engine with transmission in gear when adjusting wheels. Wheels on the ground could pull supported wheels off jackstands.

Never operate tractor with a loose rim, wheel, or hub.

IMPORTANT: Carefully follow procedure. Failure to do so could lead to wheel hub damage. Clean any paint, grease, film, rust or debris from axle shafts prior to position and installing wheel hubs and sleeves. Do NOT apply any lubricant to cap screws or threads.

1. Raise tractor on level ground and support with jackstands.

2. Install wheel and tire assembly to inner hub, using a washer on each M22 x 120 mm cap screw (A).

NOTE: Use Torque Multiplier Wrench for heavy-duty fasteners. See your John Deere Dealer.

Torque multiplier wrenches available for purchase are:

• JT05706 - Capacity - 1360 N·m (1000 lb-ft)

• D05125ST - Capacity - 2720 N·m (2000 lb-ft)

3. Tighten cap screws (A) in criss cross pattern.

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

5. Adjust tread spacing between 2302 mm (90.5 in.) minimum and 2617 mm (103 in.) maximum.

NOTE: Torque pattern is stamped on wheel hub.

6. Tighten bolts (1-10 or 1-12) in numerical order to 405 N·m (300 lb-ft).

7. Tighten bolts (1-10 or 1-12) in numerical order until bolts maintain torque.

Specification

8. Drive tractor in a "figure 8" pattern over four laps.

IMPORTANT: Insure inner hub and wheel bolts hold torque before installing outer hub and disk. This may take several drive and torque sequences.

9. Repeat drive and torque procedure a minimum of three times until all hardware holds torque.

IMPORTANT: Recheck Wheel Cap Screw Torque.

17. Check cap screw torque Every Two Hours of operation until cap screws turn less than 1/4 turn.

18. Then recheck torque Once Per Day until cap screws turn less than 1/8 turn.

19. Then recheck torque Every seven days, if cap screws move more than 1/4 turn, repeat Steps 15 and 16.

IMPORTANT: If tractor is operated with wheel sleeves loose for 4 -5 hours, it is necessary to replace sleeves.
