Main gear shaft for YD-4 platforms

This is the main gear shaft from the YD-4 standard parts set, supplied as a direct replacement for drivetrain wear or damage. It is intended for use in DP-YD4 and DP-YD4MR chassis where the original shaft needs renewing.

Functionally the shaft locates the spur gear and works with the existing gear stack and bearings. When replacing a worn shaft, check the spur gear mesh and bearing fit during reassembly to maintain drivetrain alignment and reduce play.

Installation is a straightforward swap using the existing mounting points on the gearbox assembly. Inspect surrounding components for wear at the same time, and test run at low speed after installation to confirm smooth engagement before full use.

Compatibility

  • DP-YD4
  • DP-YD4MR

Is this shaft a direct fit for DP-YD4MR?

Yes, the part is listed as compatible with DP-YD4MR and fits the standard gearbox mounting used on those chassis.

Do I need extra parts to install it?

No extra parts are required for a direct replacement, but inspect bearings and the spur gear for wear and replace as needed.

Any setup tips after fitting the new shaft?

Verify spur gear mesh, check bearing preload, and perform a low-speed test to confirm smooth drivetrain operation before full use.
