Suspension (if fitted)
Each part of the suspension must be torqued as stipulated below: ‐
1. Service and maintenance should be carried out after the first laden journey, and
thereafter every 6 months.
2. All bolts should be tightened to the recommended torque setting in the table.
3. When tightening torque arm and centre hanger bolts with taper bushes, ensure the
torque arm or equaliser is centrally located and not contacting the hanger. Check
clearance and wear of taper bushes in centre hanger and torque arm assemblies.
4. Yearly visual inspection of spring, hangers, Saddles and clamp plates; thoroughly
clean and inspect for cracks and deformation.
5. Under harsh or intensive operating conditions, maintenance should be carried out
more frequently.
