TRANSMISSION DEBRIS MONITOR

Remove full flow monitor from transmission sump case.

Remove cup and screen tube from monitor. Visually

inspect screen tube for contamination and non-magnetic debris.
Inspect external surface of monitor and chip detectors for
magnetic chips and particles. If contaminants, chips, or particles
are found, investigate to determine cause and correction.

Chapter 66

Thoroughly clean screen tube and monitor with drycleaning

solvent (C-304). Clean exterior surfaces of magnets with a
clean cloth. Install screen tube with new packing, and torque.

Connect electrical harness to monitor and short across

magnets (2 places). Verify XMSN caution light illuminates for
each magnet.

Install monitor in sump case with new packing.

MAST ASSEMBLY

Inspect mast assembly for security, nicks, dents, and

scratches. Pay particular attention to the area contacted by
main rotor hub static stops.

Inspect for evidence of oil leaks at mast bearing caps.

TAIL ROTOR DRIVE SECTION

Torque check intermediate gearbox attachment bolts.

Torque check tail rotor gearbox retaining nuts.

NOTE

Intermediate gearbox 212-040-003-023 and tail rotor
gearbox 212-040-004-009 have a 300 hour/12 month
oil change interval.

Drain oil from intermediate and tail rotor gearboxes.
