2.3.2.1.1 REMOVING AND INSTALLING THE TORSION BAR SPRINGS
The number of torsion bar springs installed in the truck depends on the version of the cabin. When the cabin
is retrofitted to a different cabin version, the number of torsion bar springs must be changed, otherwise the
cabin will be too difficult to open or close too easily.
- Remove the electrical system cover.
- Dismantle the contactor support assembly and pull it aside until the spring pack is accessible.
- Open the cabin until the weight is full removed from the torsion bar springs (all springs are flat).
- Fix the overhead guard in this position with the aid of a crane and a sling.
- Remove the clamping plates on the right and left of the spring pack.
- Install the correct number of torsion bar springs.
- Install the correct fishplates and correct number of washers.
- Fasten fishplates at the left and right of the spring pack.
- Release the cabin from the crane.
- A fine adjustment of the spring pack can be done with the adjusting screw on the tensioning lever on the
right-hand side of the cabin. Measure distance A for the adjustment.
NOTE: Distance A is measured vertically from the rear edge of the lever to the inner edge of the roof
bracket.
Lever adjustment:
Cab Model Distance A
1 40 mm
2 40 mm
3 35 mm
4 35 mm
5 25 mm
NOTE: The cabin should be able to be opened and closed without too much effort.
