MASSEY FERGUSON 410 Operators Instruction Book page 79

Front track adjustment (four-wheel drive)
NOTE: The following instruction are for wheels that
have a detachable rim and disc.
The different track widths are obtained by altering
the position of the rim in relation to the disc or by
reversing the wheels .
If the wheels are reversed, they must be transferred
to the opposite side of the tractor so as to maintain
the correct tire tread direction.
Adjustment is as follows:
1. Select the required track setting. See Fig. 116
opposite.
2. Slightly slacken either the wheel to axle, or the
rim to disc nuts, or both according to the requirements.
3. Using a jack, raise the front wheels just clear of
the ground and support on an axle stand.
4. Remove the rim from the disc, or the complete
wheel, or both and reassemble them with the rim
and disc in their new positions.
5. Oil the bolts or studs threads before fittings the
nuts, then tighten to a torque of:
Disc to axle hub
Rim to disc
IMPORTANT: At the smaller track setting, a foul
condition may occur between the tire and the tractor
or loader, if fitted, when the wheels are turned to the
full lock position.
To avoid this condition you must check by turning
the wheels to full lock, swinging the axle onto both
bump stops both sides, and adjusting the steering
stops as necessary.
Steering stop adjustment
1. Place the jack under the engine sump and raise
the tractor enough to allow the axle to swing from
one stop to the other.
2. Turn the front wheels to full lock and check that
the inside edge of the tire does not foul the tractor.
3. Carry out the same check on the other lock.
4. If necessary, adjust the steering stops (1, Fig 117)
on both sides so that a foul condition will not occur.
Tighten the lock-nuts (2) after adjustment.
CAUTION: Recheck the nut and bolt
tighteness after 10 hours(2 hours if on
loader work) re-tighten twice more at
10-hour intervals. This protects against
the loosening that occurs from assemblies settling
down.
