Flat Washer Set 10 x 14 x 1T (5pcs) — Hirobo HI2506037  [HI2506037]

Pack of thin flat washers for rotor and gearbox

This Hirobo washer kit includes five matching 10 x 14 x 1T discs intended for general helicopter maintenance and small repairs. They serve as inexpensive consumables to control axial clearance, spread bolt head load, and prevent direct metal contact on compact rotor and gearbox assemblies.

Fitting tips: check that the bore allows free movement on the chosen fastener, press the washer flush against the mating surface, and avoid excessive torque which can warp the washer and alter clearances. For precision assemblies, add or remove washers incrementally and recheck bearing rotation and gear mesh.

Adjustment use: these thin washers work well as shims to tweak rotor spacing, correct minor endplay, or align gear faces without changing shafts or housings. Stow spare pcs in your tool kit for quick roadside fixes.
