This Delrin drive gear is produced as an aftermarket replacement for HPI Savage, Savage X and Savage Fluorescent platforms, covering the 18-23T tooth counts indicated in the model name. It is intended for technicians and experienced hobbyists seeking a lower friction, quieter gear option for routine drivetrain servicing.
Use the DSAV1823T when a direct replacement is required or when fine tuning gear ratios inside the 18-23T range. The Delrin material provides reduced noise and a gentler engagement profile; inspect contact patterns and mating gear condition after installation to verify correct alignment and load distribution.
Workshop notes: confirm tooth count and hub orientation before fitting, set backlash to the recommended clearance using feeler or shim methods, torque fastenings to specification and perform a controlled break-in to validate smooth operation.
