Maytronics Dolphin M200 rear chassis adapter - 9980013

Maytronics Dolphin M200 rear chassis adapter

The rear chassis adapter (SKU 9980013) is a structural interface component that locks onto the rear section of the Dolphin robot’s chassis, securing the drive and body assemblies in precise alignment. It works in tandem with the front chassis adapter (9980012) to form the complete chassis mounting system that keeps internal components correctly seated during operation.

Function and role in the chassis assembly

The rear chassis adapter acts as the rearmost anchor point of the robot’s frame, channelling the mechanical loads generated by the drive tracks and motor unit into the chassis in a controlled manner. Without a correctly fitted adapter, the chassis halves can flex or separate, causing misalignment of the drive train and allowing water ingress into sealed cavities.

Compatible Dolphin models

This part is confirmed as a direct-fit component for the Maytronics Dolphin M200 CLI Cart. CB and has also been identified in Dolphin DX3 parts diagrams under the same SKU, indicating cross-compatibility across those platform variants that share the DX3/M200 chassis architecture.

Symptoms that indicate replacement is needed

Look out for unusual flexing or creaking of the robot body during operation, visible cracking or deformation of the rear chassis mounting points, or the chassis halves failing to clip together securely during reassembly after a service. Any of these symptoms compromises the structural integrity of the unit and should be addressed before returning the cleaner to the pool.

Why genuine Maytronics parts matter

Genuine Maytronics parts are manufactured to the exact dimensional tolerances of the original chassis tooling. An aftermarket substitute that is even fractionally out of tolerance will introduce stress concentrations at the mounting points, accelerating wear on adjacent components including the motor housing and drive-track mounts. Using genuine parts also preserves any remaining manufacturer warranty on the robot.
