The Wacker Neuson 5100021658 Front Engine Mount Kit is a genuine OEM component designed for the APT6T, APT6S, APT8T, and APT8S series self-priming trash pumps. This kit delivers a direct, drop-in fit across the full APT pump lineup, including surge brake, electric brake, cold weather, and skid-mounted configurations. As a genuine Wacker Neuson part, the 5100021658 is manufactured to the same standards as the original, ensuring correct geometry, hardware sizing, and mounting interface for your specific machine. Confirm your model number before ordering to ensure compatibility with your pump configuration.
Key Features
- Genuine OEM Isolation and Damping: — Engineered to the original mount specification, delivering the correct load-bearing stiffness and vibration isolation for APT pump engines — not a generic approximation.
- Complete Kit: — Supplied as a complete front engine mount kit, so you have everything needed for the repair in a single part number — no sourcing individual hardware separately.
- Broad APT Series Coverage: — Fits APT6T, APT6S, APT8T, and APT8S configurations, including surge brake, electric brake, cold weather, and skid-mounted variants.
- Engine Stability and Pump Alignment: — A correctly functioning engine mount holds the engine in proper alignment with the pump drive, preventing premature wear on the impeller, drive coupling, and frame — a worn or collapsed mount accelerates damage throughout the drivetrain.
- Verified Part Number: — Cross-reference part number 5100021658 against your machine's serial number and model designation to confirm the correct fit for your APT configuration.
The front engine mount kit secures the engine to the pump frame and absorbs the vibration and torque loads generated during operation. By isolating engine movement, the mount protects surrounding components — including the pump housing, drive coupling, and frame welds — from stress and fatigue cracking. When an engine mount collapses or deteriorates, the engine shifts out of alignment, causing excessive vibration, accelerated wear on drivetrain components, and potential structural damage to the pump assembly.
