GPH 346 Compatible Counter Gear 14T HI0403244 HIROBO  [HI0403244]

Gearfit summary for GPH 346

The HIROBO HI0403244 counter gear is supplied as a 14-tooth replacement intended for the GPH 346 line of model helicopters. The counter gear conveys rotation from the motor pinion into the main gear train, so accurate seating and mesh are key to maintain efficient power transfer and minimise wear.

Installation notes: inspect the mating shaft and bearings before installation, ensure the gear sits square on the countershaft, and set a cautious initial gear mesh. Retain the original fixing hardware where possible and verify unobstructed rotation of the shafts after fitting.

Maintenance and tuning: replacing a worn or mismatched counter gear will affect timing and gear lash; fitting the correct 14T component returns the intended gear ratios and helps preserve consistent flight behaviour. Carry out routine inspections to spot early tooth or bearing deterioration.
