Replacement counter gear details

This HIROBO HI0403244 counter gear is a specified 14T spare for the GPH 346 range of model helicopters. In operation the counter gear passes torque from the motor pinion across the gear train, making correct alignment and mesh essential for efficient power transfer and reduced component wear.

Installation notes: before fitting examine the countershaft and bearings for damage, verify the gear locates squarely on the shaft, and initially set a slightly conservative mesh. Use the original retaining hardware where appropriate and confirm free, smooth rotation of the driven shafts before normal operation.

Tuning effects: changing a worn or incorrect counter gear changes timing and lash; fitting the correct 14T item restores expected gear ratios and predictable flight handling. Regular scheduled checks will reveal early tooth or bearing wear.

How does replacing the counter gear alter timing?

A worn or wrong-tooth counter gear changes the effective gear ratio and lash between pinion and main train, shifting timing. Installing the specified 14T restores the designed ratio and helps maintain the original timing characteristics.

What checks should I do after fitting HI0403244?

After fitting, confirm axial and radial play are within limits, recheck mesh at rest, run low-power functional tests and listen for abnormal noise. Reinspect after the first few flights to ensure the mesh has not shifted.
