SELF-LOADING BALE WRAPPER
SPRINTER 1500
- The jack must be placed next to the bolts (2) which fix the axle (1) to the bottom frame
(3), see Figure 40. Recommended jacking points are indicated by an arrow. The jack has
to match the bale wrapper's kerb weight.
Check the running axle bearings for play

By rotating the wheel slowly in two directions, check if the movement is smooth and the wheel
rotates without excessive resistance or jamming.

Move the wheel to rotate very quickly to check for unnatural sounds from the bearing.

Grip the wheel's upper and lower end to try to feel if there is play.
- You can use a lever placed under the wheel, with its other end resting on the ground.

Repeat the procedure for the other wheel.
A damaged or missing hub cap will let dirt and moisture penetrate the hub, resulting in much
faster wear of bearings and hub seals. Bearing service life depends on the conditions the bale
wrapper is operated in, load, vehicle speed and lubrication conditions.
If play is perceptible, the bearings must be adjusted. Unnatural sounds from the bearing can be signs of
excessive wear, contamination or damage. In such case, the bearing, together with the sealing rings, must
be replaced with new ones or cleaned and lubricated again. Check the condition of the hub cap and
replace it if necessary. The bearing play check can only be carried out when the bale wrapper is connected
to the tractor. Ensure there is no load on the machine.
Checking the running axle bearings for play:

after riding the first 1,000 km,

before any intensive use of the bale wrapper,

every 6 months of use or after riding 25,000 km.
Before starting work, read the instructions manual of the jack and follow the manufacturer’s
guidelines. The jack must stand stable on the ground and against the running axle. Make sure that
the bale wrapper does not roll during the check for play in the running axle bearings.
7.6.2 Removing play in the running axle bearings
Preparatory activities

Follow the procedure in Section 7.5.1 to prepare the tractor and the bale wrapper for adjustment
Removing play in the running axle bearings

Remove the hub cap (1), see Figure 41

Remove the locking pin (3) which secures the castle nut (2).

Tighten the castle nut to remove play.
- The wheel should turn with slight resistance.

Loosen the nut by at least 1/3 turn to line up the nearest groove of the nut with the hole in the
running axle stud. The wheel should turn without any excessive resistance
- The nut must not be over-tightened. Too strong tightening is not recommended due to
the worse bearing operation.
