Slewing ring clearance check
The clearance between the slewing rings increases during the life of the slewing bearing because of
wear. The amount of clearance should therefore be checked regularly. The measured values should
then be compared to other measurements taken over time using an identical method.
The measurement should be taken using a centesimal comparator when the turret is stationary.
Proceed as follows:
1)
Thoroughly clean the points on which the measurement to be taken.
2)
Lift the boom up until it is at 0° and extend it completely until it reaches its maximum
extension with the turret aligned with the axis of the vehicle.
3)
Position the comparator as indicated in the diagram (Fig. 8.10, 1) measure the
Amax axial clearance;
The measured value must be less than or equal to:
Amax = 1.35 mm
4)
If the measured value is greater, contact an authorised service centre
5)
Position the comparator as indicated in the diagram (Fig. 8.10, 2) and measure the
Bmax axial clearance;
The measured value must be less than or equal to:
Bmax = 1.50 mm
6)
If the measured value is greater, contact an authorised service centre.
