Components To Track

ChatterFix builds these as child assets under jaw crusher, so failure history and PM completions attach to the component that actually failed — not just to the machine.

How Jaw Crusher Actually Fails

The failure modes worth designing a maintenance schedule around — in rough order of what they cost when they happen.

  • A jaw plate past the site wear limit still running
  • A toggle seat nobody looked at
  • A flywheel guard off
  • Bearing heat or a leak with no history
  • Someone in the cavity on this work order

What To Measure

Recording that a PM was "done" tells you nothing next quarter. These are the readings that let you see a failure coming — and the reason ChatterFix captures measurements against the asset rather than just completions.

  • Jaw plate wear with the crusher locked out
  • Toggle seat
  • Flywheel guard
  • Bearing housing heat history and leaks
  • That the cavity was not entered

Spares Worth Stocking

The parts whose absence turns a short repair into a long outage.
