5.8 Other Key Components
IMPORTANT: Before starting, safety checks on tractor and machine must be carried out with regard to:
functionality, road safety and accident prevention rules.
5.8.1 Pins & Bushes
Pins
Pins should be inspected regularly to ensure they are not worn, damaged or loose.
Ensure all pins and accompanying fasteners are tight and routinely checked following the guidance given on the
Maintenance Sheet; see Section 5.10.
Ensure that the pins have not been worn in such a way to create a step. Make sure the pin is not bent and the
head is not damaged. If in any doubt, replace.
Bushes
Figure 5.76 – New & Worn Bush Comparison
The machine should be inspected regularly to ensure the bushes are not worn. Worn bushes should be replaced
when there is excess movement. Bushes will wear oversize or oval with indication on the interior showing the oil
galleries being worn away. To prevent premature wear grease the bushes (where applicable) following the
greasing schedule; see Section 5.2.4.
5.8.2 Skids
Equipment Required
10mm allen head socket/key
17mm hex socket/spanner
Figure 5.77 – SR460/620/820 Wing Skid
McConnel machine skids are fitted to protect the machine deck fabrications from permanent damage. Premature
wear can be caused to the skids through the machine being set too low, allowing the skids to drag along the
ground causing an earlier requirement for replacement. Dragging the skids on the ground or running the skids
into solid objects can contribute to early frame failure of the machine. Replace worn skids as required. Failure to
replace skids and using the machine without will cause permanent damage to the deck fabrications.
