    Key for Test Results Table

  • R = Retracts more than 10 mm (3/8 in.)
  • E = Extends more than 10 mm (3/8 in.)
  • NC = No Change or less than 10 mm (3/8 in.)
  • NC/E = No Change or Extends

NOTE: When a main frame cylinder is leaking, wing-frame on same side will extend in most cases.

In some cases, after repairing main frame cylinder(s), a wing-frame cylinder leak may be discovered.
