6.4.6 BASIC TANDEM AND BASIC HALF-TANDEM SUSPENSIONS
After the first laden journey, before intensive use or every 6 months (See Figure 9.4.1):
- Tighten all the centre clamping bolts and axle U-bolts to the recommended torque. Tighten the nuts diagonally
(See Section 6.4.8 U-BOLT TIGHTENING TORQUE).
- Retighten all the nuts and screws on the suspension (spring shackles, rocker, equaliser bearings, spring bolts,
springs)
- Lubricate the rocker bearings and the spring bolts.
Under harsh or intensive operating conditions, maintenance should be carried out more frequently.
Every year (See Figure 9.4.2):
- Check the play between the bushings Item 2 and the rocker shafts Item 1 and, if there is excessive play, replace the
worn parts.
- Check the rocker Item 3 and the spring shackles Item 4 for wear (spring bearing surface) and replace these parts if
they are very worn.
- Check the general condition of the springs Item 5, clean them thoroughly and brush the sides of the springs to
check for cracks.
- If there is any play between the springs and the axles, check the whole of the clamping system: clamping plates
Item 8, spring alignment Item 9, brides Item 10.
Maintenance of half-tandem suspensions without rocker bars is the same as for simple tandem suspensions with
rocker.
