The Wacker Neuson 5100021686 is a genuine OEM Face Plate designed for the APT4T, APT4S, APT6T, APT6S, APT8T, and APT8S series towable pump units, covering standard, cold weather, surge brake, electric brake, and skid-mounted configurations. As a factory-original component, the 5100021686 is manufactured to the same exacting tolerances as the part it replaces, ensuring a direct, accurate fit across the full APT pump lineup. This Face Plate is an essential structural and functional element of the pump assembly, and sourcing a genuine OEM replacement ensures the unit continues to perform as Wacker Neuson intended. Confirm your machine's model number before ordering to ensure compatibility with your specific APT configuration.
Key Features
- Genuine OEM Construction — Manufactured by Wacker Neuson to original production specifications, ensuring correct material thickness, surface finish, and dimensional accuracy for the pump face interface.
- Direct Drop-In Replacement — Engineered to seat and secure exactly as the original, with matching bolt patterns and face geometry that align without modification to the pump housing.
- Broad APT Series Coverage — Compatible with APT4T, APT4S, APT6T, APT6S, APT8T, and APT8S models, including standard, cold weather, surge brake, electric brake, and skid-mounted variants.
- Maintains Pump Integrity — A properly fitted face plate keeps the pump assembly sealed and structurally sound; a damaged or ill-fitting plate can compromise performance and allow contaminant ingress.
- Verified Part Number — Cross-reference part number 5100021686 against your machine's serial plate or parts manual to confirm fitment before installation.
The face plate forms a critical interface on the pump assembly, providing a flat, precisely machined surface that seals and supports the pump's working components at the front of the housing. It ensures internal pressure is contained and that mating components align correctly during operation. When a face plate becomes cracked, warped, or corroded, the integrity of the pump assembly is compromised — leading to fluid loss, misalignment of internal parts, and potential pump failure in the field.
