Technical Overview of the Delrin Main Gear

The GPM Delrin main gear is specified for HPI Savage 21 applications where material durability and consistent gear mesh are priorities. The 49-tooth geometry is chosen to promote uniform tooth contact and to minimise frictional losses in the drivetrain while preserving component life under repeated loading.

Technical Highlights

  • Formulated for HPI Savage 21 compatibility
  • Delrin construction for predictable wear characteristics
  • 49T tooth count optimised for steady engagement
  • Helps reduce shock transfer to other driveline components

What inspection points should a technician check after fitting?

Confirm concentric seating on the spur boss, verify pinion to spur mesh across the face width, and check for any lateral play that could cause accelerated tooth wear.

How does Delrin behaviour compare to nylon under load?

Delrin typically offers lower friction and more stable dimensional behaviour under heat than some nylons, which can translate to steadier mesh and longer service intervals in high-use scenarios.

Any recommended checks after the first running session?

After an initial run, re-torque fasteners, inspect tooth profiles for unusual wear, and confirm the mesh remains consistent across the gear face.
