The Husqvarna 505587301 Belt Tension Arm is a genuine OEM component designed for the Soff-Cut150 and Soff-Cut150PACE early entry saws. As a direct Husqvarna OEM part, it is manufactured to the exact specifications required for correct belt engagement and tensioning on these machines. This arm installs as a direct replacement, restoring proper drive belt alignment and tension without the guesswork that comes with non-OEM alternatives. DHS Equipment supplies this part to help keep your early entry saw performing at its best.
Key Features
- OEM-Spec Tensioning Geometry — Manufactured to Husqvarna's exact pivot dimensions and arc, ensuring the arm applies the correct, consistent pressure to the drive belt throughout its travel.
- Direct OEM Replacement — Engineered to match the original mounting points on the Soff-Cut150 and Soff-Cut150PACE, allowing straightforward installation against the existing hardware.
- Confirmed Fitment — Compatible with the Soff-Cut150 and Soff-Cut150PACE early entry saws; cross-reference 505587301 against your parts diagram before ordering to confirm the correct application.
- Restored Belt Drive Performance — A correctly tensioned belt arm maintains steady blade speed and power transfer, critical for clean, accurate cuts in green concrete where blade control directly affects joint quality.
- Genuine Husqvarna Quality — Produced as an authorized OEM component, this arm meets the same material and dimensional standards as the part that left the factory, supporting long-term drivetrain integrity.
The Belt Tension Arm maintains the correct load on the drive belt that transfers power from the engine to the blade assembly. When this arm is worn, bent, or damaged, belt tension becomes inconsistent — leading to belt slip, uneven blade speed, and reduced cutting accuracy. On an early entry saw like the Soff-Cut150, where precise timing and consistent blade engagement are essential for crack-control joint work in freshly poured concrete, a failed tension arm can compromise cut quality and accelerate belt wear. Replacing this component with the correct OEM part restores the designed tension profile and protects the rest of the drive system.
