AS REQUIRED
f. Rotate the outer wheel so the lugs lock
together, one on the inside of the rim and two
on the spacer. Raise the axle of the tractor up
or lower it down to assist the spacer in
entering the diameter of the outer wheel.
Once the outer wheel is positioned on the
spacer, pull the two tie rods through the
brackets, 1, on the outer wheel rim. Install a
flat washer and flanged nut on each of the
two tie rods and snug the nuts to hold the
assembly in place. Install the remaining tie
rods with flange nuts on the inner wheel and
through the outer wheel brackets.
NOTE: The outer wheel must be inset
(narrow tread width) thesame as the inner
wheel when installed.
NOTE: Install the wheels so that both
inner and outer treads face the same
direction.
g. Install remaining outer flanged wheel nuts, 1,
and washers, 2, onto the ends of each tie rod.
Tighten the outer wheel nuts to draw the
wheels together by gradually cross-torquing
to 300 N⋅m (220 ft. lbs.) on the outer flanged
wheels. Do not overtighten the bolts or
thread damage may result. 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.
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.
IMPORTANT: Do not lubricate the threads of
the tie rods with any type of grease, oil, or
lubricating spray.
