HPI Savage 21 49T Delrin Spur Gear DSAV1049T by GPM  [DSAV1049T]

Part summary

This spare main spur is made for the HPI Savage 21, a 49T unit moulded in Delrin for consistent dimensions and low friction. It serves as the primary spur gear and is designed for direct replacement in compatible Savage 21 gearboxes.

As the primary spur, the gear governs mesh with the pinion, the final drive engagement and the way power is delivered to the drivetrain. Delrin typically gives more stable friction characteristics and better dimensional control than common nylon stock gears.

Installation is straightforward for Savage 21 owners: remove the gearbox cover, check bearing alignment and shaft seating, fit the spur onto the shaft and set backlash to a correct mesh before closing the gearbox. Check pinion teeth and bearing play while you are servicing the unit.

Item supplied as a single piece, suitable for routine service or modest tuning where Delrin tolerance and machining repeatability are preferred in replacement parts.
