The Husqvarna 505888001 Rear Bottom Board Shaft Kit Gx4000 is a genuine OEM replacement designed for the Soff-Cut4200 early entry saw. Sourced directly from Husqvarna, this kit delivers the exact components and dimensional specifications required to restore the rear shaft assembly on the Soff-Cut4200 to proper operating condition. DHS Equipment supplies this part to help keep your equipment running through demanding green-concrete cutting schedules.
Key Features
- Genuine OEM Shaft and Bearing Precision — manufactured to Husqvarna's dimensional tolerances for the GX4000 bottom board system, ensuring correct shaft alignment and smooth rotation under load.
- Complete Kit Format — includes all rear shaft assembly components needed for the repair, so there are no missing pieces when you open the box and begin the job.
- Confirmed Soff-Cut4200 Fitment — engineered specifically for the Soff-Cut4200 early entry saw; cross-reference part number 505888001 against your parts diagram before ordering to verify compatibility.
- Restores Blade Depth Control — a correctly functioning rear shaft assembly keeps the bottom board tracking true, which is critical for achieving the consistent shallow cuts that prevent random cracking in green concrete.
- Structural Assembly Quality — as an OEM kit, every included component meets the same material and hardness specifications as the parts originally installed at the factory, supporting the long service intervals expected from Husqvarna Soff-Cut equipment.
The rear bottom board shaft on an early entry saw transmits rotational force from the drive system to the cutting assembly while maintaining the precise blade depth that defines early-entry green concrete sawing. When the shaft or its associated components wear or become damaged, the bottom board loses stable tracking, which can result in blade deflection, uneven joint depth, and surface damage to the slab. Replacing the full kit — rather than individual components — ensures every element in the assembly works together correctly and that wear on any single piece does not compromise the repair.
