Track Width Adjustment with Sliding Axle

IMPORTANT: Never select a track different from the instructions in this manual.

NOTE: If the total machine width (combination of track width and tires) is more than 2.55 m, in some countries it may be necessary to install additional warning signs.

NOTE: To adjust track width, remove wheel for better access.

With the sliding axles, the track width can be changed by sliding the axle ends in or out after having jacked up the machine. In the case of row crop tires, the track can be adjusted from 1.50-2.00 m or from 1.72-2.25 m respectively, depending on type of axle. The minimum track for flotation tires is 1.80 m.

The sliding axle ends are clamped to the axle with four fixation hex nuts (D) on each side. An additional set screw (B) on each side of the axle allows accurate adjustment of the track width in steps of 50 mm. If the set screws (B) are not fixed, stepless track adjustment is possible.

The tables on the next pages give the possible combinations. Only the settings given may be used. Always make sure that the axle ends are secured with four bolts on each end.

If the wheels are reversed, or the track width is adjusted, make sure that the machine is secured when jacked up. Always place additional support blocks under the axle.

The specified torque for the wheel nuts (M22x1.5) is 480 N·m. The nuts must be tightened in a cross pattern and checked regularly.

When the sliding axle fixation hex nuts (D) and set screws (B) are loosened, the axle ends can be slid in or out, to adjust the desired track width.

3. Tighten hex nuts (D) and lock nuts (E) evenly to 110 N·m.

4. Then tighten set screw (B) with low force.

5. Between the clamp and the block a distance (F) of at least 3 mm must remain.

The table below shows the track width adjustment for the sliding axle from 1.50 to 2.00 m. For track widths from 1.50 up to 1.75 m the wheels should be fitted to the axle ends with positive offset (convex). If the wheels are exchanged between left and right, a negative offset (concave) is achieved. If the axle ends are then slid in completely to the first adjustment hole, the track width reaches 1.80 m. From there on, the track width can be extended up to 2.00 m by sliding the axle ends out again.

NOTE: The axles have a camber of - 0.5%. For the different settings shown in the tables, take this camber into account. The track width can change slightly when loading the tank.

The table below shows the track width adjustment for the sliding axle from 1.72 to 2.25 m. For track widths from 1.72 up to 2.05 m the wheels should be fitted to the axle ends with positive offset (convex). If the wheels are exchanged between left and right, a negative offset (concave) is achieved. If the axle ends are then slid in down to the third adjustment hole (flange-flange 1948 mm), the track width reaches 2.10 m. From there on, the track width can be extended up to 2.25 m by sliding the axle ends out again.

NOTE: The track width of the tires is calculated with -0.5% camber of the wheels, as integrated in the design of the axle.

The table below shows the track width adjustment for the sliding axle (1.72 to 2.25 m) for flotation tires. With flotation tires the track width can be adjusted from 2.02 to 2.25 m only. The wheels should be fitted to the axle with negative offset (concave). If the axle ends are then slid in completely to the first adjustment hole, the track width reaches 2.02 m. From there on, the track width can be extended up to 2.25 m by sliding the axle ends out again.
