Creality K2 Plus Tray Shaft Kit (MPN 4004150039) — Replacement tray shaft for Creality K2 Plus 3D printer

The Creality K2 Plus Tray Shaft Kit is a replacement set of mechanical components intended to restore the linear movement and alignment of the build plate/tray assembly on the Creality K2 Plus 3D printer. It contains the parts needed to replace worn or damaged tray shaft elements so the tray can move smoothly and maintain correct positioning during printing. The kit is designed for repair or routine maintenance of the printer’s tray mechanism to help preserve print stability and dimensional accuracy.

Advantages

This tray shaft kit allows targeted replacement of the tray’s moving components without the need to replace larger assemblies, reducing downtime and repair cost. By restoring proper shaft geometry and bearings or bushings included in the kit, it helps eliminate play or binding in the tray motion and supports consistent bed alignment. The kit is compatible with the mechanical design of the Creality K2 Plus and is intended to fit the original mounting points and tolerances.

Suitable for

• Repairing a Creality K2 Plus with worn, bent, or seized tray shaft components
• Routine maintenance to restore smooth tray movement and reduce mechanical noise
• Replacing damaged parts after a crash or improper handling of the build plate
• Workshops and service centres that maintain Creality K2 Plus printers

When it may not be suitable

The kit is specific to the Creality K2 Plus tray mechanism and may not fit other Creality models or third‑party printers that use different tray geometries or mounting arrangements. If the printer has broader frame damage, warped structural parts, or electronics and sensor failures affecting bed leveling, replacing the tray shaft alone may not resolve printing issues.

Key specifications

• Compatibility: Creality K2 Plus build plate/tray mechanism
• Contents: tray shaft components and associated mechanical parts required for tray movement (as supplied in the kit)
• Function: restores linear motion and alignment of the build plate/tray assembly
• Application: repair and maintenance of the tray mechanism for stable printing performance

How to use

Power down the printer and follow the manufacturer’s service instructions before beginning. Remove the build plate or access covers to expose the tray shaft assembly, note original orientations and fastener locations, and then remove the old shaft components. Install the replacement shaft parts from the kit, ensuring bearings, bushings, and mounting points are seated correctly and fasteners are torqued to recommended values. After reassembly, check tray travel for smoothness and correct alignment, and perform a test print or bed leveling routine to confirm restored performance.

What to consider before purchase

• Verify that your printer model is the Creality K2 Plus and that the tray mechanism requires this specific replacement kit
• Assess the printer for additional damage (frame, electronics, sensors) that this kit will not address
• Confirm you have basic tools and mechanical skill or access to service support for replacement

Usage recommendations

Use the kit as part of preventive maintenance when tray movement shows increased friction or play. After installation, perform a full bed leveling and run a small test print to validate motion smoothness and alignment before resuming normal production.
