Buhler 2335, 2425, 2290, 2375, 2360 manual AS Required

SECTION 3 - LUBRICATION AND MAINTENANCE

AS REQUIRED

i. Draw in the wheels by gradually cross-torquing the outer wheel flanged nuts, 8, to 300 N⋅m (220 ft. lbs.). Do not overtighten the bolts or thread damage may result.

IMPORTANT: Do not lubricate the threads of the tie rods with any type of grease, oil, or lubricating spray.

NOTE: Special tool BLR20025 deep well socket is available to assist in tightening the outer wheel nuts. Order the tool from SPX/OTC tool company.

j.Be sure that the spacer is entering the diameter of the inner and outer wheels evenly and without any distortion of the spacer or wheels.

k. Be sure the flanged backing nut, 3, is against the inner wheel disc. Hold the tie rod with a pipe wrench or vise grip pliers to prevent rotation during the torquing procedure. Torque the flanged backing nuts, 3, to 440 N⋅m (325 ft. lbs.). The inner tie rod flanged locknut should not need torquing. It will be drawn up tight when the backing nut is torqued.

NOTE: Special crowfoot wrench BLR20027 is available to torque the backing nuts. Order the tool from SPX/OTC tool company.

l.Install jam nuts (not shown) on top of the outer wheel nuts, 8, and torque them to 320 N⋅m (235 ft. lbs.).

m. Repeat the above procedure for the remaining three sets of duals.

n.Drive the tractor steering from lock to lock. Park the tractor and recheck the torques on the outer wheel nuts as detailed in Steps i and l.

REMINDER

All wheel mounting hardware should be re-tightened to the specified torque after the first hour of operation, then after every three hours of operation for the first day. Re-tighten to the specified torque daily until wheel hardware maintains specified torque.
