This kit delivers an exact-match replacement for the rear bottom bracket shaft assembly, ensuring the drivetrain and blade depth system return to correct operating alignment. DHS Equipment supplies this part to help keep your early entry saw performing at spec across every green-concrete application.
Key Features
- Genuine OEM Construction — Manufactured to Husqvarna's dimensional and material specifications, ensuring the shaft and bracket components seat and rotate exactly as the original assembly did.
- Complete Kit Format — Supplied as a matched assembly, so all shaft and bracket components are replaced together — eliminating the risk of mismatched wear between old and new hardware.
- Confirmed Fitment — Engineered specifically for the Soff-Cut150, Soff-Cut150E, and Soff-Cut150PACE early entry saws; cross-reference 505876201 against your parts diagram before ordering.
- Restored Blade Alignment — A correctly seated rear bottom bracket shaft maintains precise blade tracking and depth control, which is critical for clean, consistent early-entry cuts in green concrete.
- Verified Part Number — Part number this part is the Husqvarna OEM reference for this kit; use it to confirm you are ordering the correct assembly for your machine variant.
The rear bottom bracket shaft assembly supports and positions the blade-side drivetrain at the base of the Soff-Cut150 early entry saw. It keeps the blade arbor and associated rotating components in precise alignment so the saw can score green concrete at the correct depth without wandering or binding. When this shaft or its bracket components wear or become damaged, blade tracking deteriorates, cut quality suffers, and continued operation can accelerate wear on surrounding drivetrain components — making timely replacement essential to maintaining cut accuracy on the slab.
