What the SLIDER does
Sacrificial contact pieces, sliding faces and front-end components that take abrasion directly so the assemblies behind them do not. They sit at the working end of the machine, in the dust and water coming back from the hole.
Signs it needs replacing
- Loss of original profile or thickness
- Grooving, scoring or polishing on the contact face
- Increased play in the assembly they locate
- Wear starting to appear on the parent component
Before you fit it
Replace before the piece wears through. Once the sacrificial face is gone, damage moves into the part it was fitted to protect and the repair cost changes scale.
General guidance for this class of component. Always work to the torque figures, clearances and service intervals in your machine's own manual.
