The Wacker Neuson Backplate is a genuine OEM component designed for the GPS9700, GPS8500, and GS series portable generators as well as the PTS4V and PTS4V(I) centrifugal trash pump lines. As a direct factory replacement, this part is sourced through Wacker Neuson's authorized supply chain and carries the same specifications as the component originally installed at the factory. It is the correct choice for GPS9700, GPS8500, GS8.5V, GS9.7V, and PTS4V series equipment, covering a wide range of model configurations across the lineup.
Key Features
- Genuine OEM Construction — Manufactured to the exact dimensional and material tolerances Wacker Neuson specifies for the backplate position, ensuring structural integrity at the rear housing interface.
- Direct Drop-In Replacement — Matches the original mounting pattern and fastener layout so it installs against the existing housing without modification to surrounding components.
- Broad Model Coverage — Fits GPS9700, GPS8500, GS8.5V, and GS9.7V portable generators as well as PTS4V and PTS4V(I) centrifugal trash pumps across multiple production configurations.
- Restores Proper Housing Alignment — A worn or cracked backplate compromises the sealing and alignment of internal rotating components; replacing it promptly keeps the machine running within spec.
- Verified Part Number — Ordering by Wacker Neuson part number 5000208221 confirms you are receiving the correct backplate for your specific model variant, eliminating guesswork.
The backplate serves as a structural rear closure for the engine or pump housing, providing a rigid mounting surface that maintains the alignment of internal components such as the crankshaft, rotor, or impeller assembly. It also plays a role in containing lubricants and directing airflow or fluid pathways within the unit. When a backplate becomes cracked, warped, or otherwise damaged, it can allow contaminants to enter the housing, cause vibration from misalignment, and lead to accelerated wear of internal parts — making timely replacement essential to keeping the machine operational.
