The Wacker Neuson Ax-42 Belt is a genuine OEM drive belt designed for the BFS 1318AS and BFS 2020AS self-propelled walk-behind floor saws. Sourced directly from Wacker Neuson, this belt matches the original specification installed at the factory, ensuring correct tension, grip, and load transfer right out of the box. If your saw is losing power to the blade, slipping under load, or showing visible belt wear, the is the correct OEM replacement to restore full cutting performance.
Key Features
- OEM-Matched Drive Profile — Manufactured to the exact Ax-42 cross-section and length specification, maintaining the correct tension and wrap angle on the drive pulleys for consistent power delivery.
- Direct Drop-In Replacement — Routes onto existing pulleys and tensioners without adjustment or modification, simplifying belt changes in the field.
- Fits BFS 1318AS and BFS 2020AS Floor Saws — Confirmed fitment for both the self-propelled BFS 1318AS and the BFS 2020AS walk-behind slab saws.
- Sustained Cutting Power — A correctly tensioned belt transfers full engine output to the blade drive system; a worn or slipping belt starves the blade of power and leads to uneven, labored cuts in concrete and asphalt.
- Blade Drive Safety — A compromised drive belt can slip or snap under load during a cut, creating an unpredictable loss of blade speed. Replacing the belt on schedule keeps drive power consistent and the cut controlled.
The drive belt on a walk-behind floor saw transfers power from the engine to the blade spindle, making it one of the most load-bearing components in the drivetrain. On the BFS 1318AS and BFS 2020AS, the Ax-42 belt runs under sustained tension and heat during every cut through concrete, asphalt, or masonry. Over time, belts stretch, crack, or glaze, causing slippage that robs the blade of speed and puts extra strain on the engine. Replacing the belt at the first sign of wear keeps the saw cutting cleanly and prevents secondary damage to pulleys and bearings.
