Hirobo HI2506043 Flat Washer 6x22x1.3 mm Plastic for Helicopter General Parts  [HI2506043]

Plastic flat washer for rotorcraft assemblies

Classified as a helicopter general part, this plastic flat washer corresponds to the 6 x 22 x 1.3 mm size in the product identifier. It functions as a thin spacer that reduces bearing stress by increasing contact area between fasteners and mating surfaces.

Maintenance advice: sit the washer flat on the mating face, keep parts and fasteners free of grit, and avoid excessive torque which can deform plastic washers and change spacing. Replace when the washer no longer remains flat or retains its specified thickness.

Tuning benefit: using this 1.3 mm washer is a straightforward way to make precise clearance changes for alignment and preload adjustments, helping to tame unwanted vibration or correct minor misalignment without replacing major components.
