HPI Savage Nitro Off-Road 53T Main Spur Gear Replacement - JR-CHP-SAV-039 by Jazrider  [JR-CHP-SAV-039]

53T main spur gear: fit and installation tips

This 53-tooth spur gear is a direct-fit RC-scale replacement designed for HPI Savage Nitro Off Road Series vehicles, supplied under part code JR-CHP-SAV-039. Manufactured from POM with a black finish, the gear functions as the main gearbox spur that meshes with the pinion to transfer motor power to the drivetrain.

Installation focus: inspect each gear tooth for signs of wear, set a proper mesh with the existing pinion, and ensure the gearbox housing and bearings are clean before fitting. The item is supplied as a single spur gear intended to replace a worn or damaged main gear on compatible Savage models.

For setup, keep pinion-to-spur mesh conservative to reduce premature wear; changing pinion size or motor output should trigger a recheck of engagement. This is an RC-scale accessory intended for model vehicle use only.

Fit this JR-CHP-SAV-039 53T spur when the original main gear shows wear; perform basic mesh checks at installation and include drivetrain inspection in routine maintenance.
