Wacker Neuson 5100079388 Motor Loncin G420FA-BQ CE

The Wacker Neuson Motor Loncin G420FA-BQ CE is a genuine OEM power unit designed for the BFS1350c floor saw. Sourced directly through Wacker Neuson's authorized parts channel, this motor matches the original specification exactly — ensuring correct output, proper mounting alignment, and full compatibility with the BFS1350c drivetrain. When your floor saw is down, fitting the right motor matters: the is the direct OEM replacement, so you're not guessing on fitment or performance.

Key Features

• OEM-Matched Power Output — Loncin G420FA-BQ CE engine meets the exact displacement and output spec the BFS1350c was engineered around, so blade speed and cutting performance are restored to original levels.
• Direct-Mount Replacement — Bolt pattern, shaft dimensions, and mounting configuration mirror the original installation, allowing a straightforward swap without fabrication or adaptation.
• Confirmed BFS1350c Fitment — Verified for the Wacker Neuson BFS1350c floor saw; always cross-reference your machine number against part number 5100079388 before ordering.
• CE-Certified Compliance — The CE designation confirms this motor meets applicable European conformity standards, supporting regulatory compliance for worksites where certified equipment is required.
• Restored Cutting Reliability — A worn or seized motor causes loss of blade torque, inconsistent cut depth, and unplanned stoppages; replacing it with the correct OEM unit brings the machine back to full operational capacity.

The Loncin G420FA-BQ is a four-stroke gasoline engine that serves as the primary power source for the BFS1350c floor saw, driving the blade spindle through the machine's transmission to deliver the torque needed for concrete and asphalt cutting. When the motor runs correctly, blade speed stays consistent and cutting depth remains controllable; when it begins to fail — through wear, seizure, or loss of compression — the saw loses power progressively, cutting performance deteriorates, and the machine will eventually stop running altogether. Replacing the motor with the correct OEM unit restores the power curve the saw was designed to operate on.
