Service part for GPH 346 drivetrains

The HIROBO HI0403244 is supplied as a 14T counter gear listed for use on GPH 346 model helicopters. It transmits rotation from the motor pinion into the main gear train, so accurate mesh and alignment reduce wear and support dependable power delivery.

Installation notes: check the mating shaft and bearings for play or scoring before installation, make sure the gear sits square on the countershaft, and set a cautious gear mesh before attempting full-throttle runs. Retain and reuse the original fasteners where possible and confirm smooth free spin after fitting.

Maintenance and tuning: fitting the correct 14T gear corrects intended ratios and restores expected timing. Inspect teeth and bearing surfaces periodically to detect early degradation and to keep flight behaviour consistent.

What signs indicate the counter gear needs replacing?

Look for chipped or rounded teeth, unusual backlash, or vibration that persists after checking mesh. Bearing roughness or shaft wear at the gear seat are also strong indicators to fit a new unit.

Should I renew bearings when fitting this gear?

Inspect bearings closely; if there is any roughness or endplay, replace them. Fresh bearings ensure the new HI0403244 gear runs true and will extend service life of the drivetrain.
