Rear Wheel Track Adjustment - New Holland T7030 Operator's Manual

REAR WHEEL TRACK ADJUSTMENT

Your tractor may be fitted with a fixed flange type or
bar type rear axle. With a fixed flange type axle rear
wheel track adjustment is effected by changing the
wheel rim relative to the centre disc, the rim and/or
the disc relative to the axle hub or by inter--changing
the rear wheels.
With bar axles, the same method of adjustment
applies but with the added advantage of being able
to move the wheel hub on the axle shaft. This
provides an infinite range of adjustment between the
narrowest and widest settings.
CAUTION
Your tractor is produced with lights that meet lighting
regulations when operating or travelling on the public
highway. If the wheel track setting is adjusted beyond
the initial factory position then you may be required
to reposition the lights or fit auxiliary lighting to
comply with legal requirements. Additionally, before
travelling on the highway, ensure that the overall
tractor width does not exceed the maximum
permitted in your country.
CAUTION
Tractor wheels are very heavy. Handle with care and
ensure, when stored, that they cannot topple and
cause injury.
NOTE: There are four different designs of centre
disc dependent upon tyre size and tractor model.
The centre discs shown are as follows:
Square centre disc -- variable track (Type 1)
Round centre disc -- variable track (Type 2)
Cast centre disc -- variable track (Type 3)
Round centre disc -- fixed track (Type 4)
NOTE: Variable track wheels (type 1, 2 and 3), are
not available on tractors with 50 Km/h transmission.
The type of centre disc installed will affect the track
setting. Identify the type of centre disc fitted to your
tractor wheels, then refer to the following table and
Figure 219 to see the wheel rim and disc positions
necessary to achieve the required track setting.
WARNING
Never operate the tractor with a loose wheel rim or
disc. Always tighten nuts to the specified torque and
at the recommended intervals.
