Key Features
- OEM-Specified Dimensions — Manufactured to the exact 3/8" x 1 1/2" specification required by Husqvarna, ensuring correct torque transfer between mating components without slippage or play.
- Direct Drop-In Replacement — Machined to match the original keyway geometry of the Soff-Cut4000, so this key seats flush and locks securely without any modification to the shaft or hub.
- Soff-Cut4000 Compatibility — Verified fitment for the Soff-Cut4000 early entry saw, a purpose-built green-concrete cutting machine used for early-entry joint sawing on fresh slabs.
- Positive Shaft Lock — A properly fitted key prevents relative rotation between the shaft and hub, maintaining blade alignment and consistent cutting depth — critical for early-entry green-concrete work where precision matters.
- Genuine Husqvarna OEM Quality — Produced to the same material and tolerance standards as the original, so fit and function match what came off the assembly line.
A drive key is a small but essential component that locks a rotating shaft to a hub, pulley, or blade assembly, ensuring that torque is transmitted evenly without slipping. On an early entry saw like the Soff-Cut4000, precise blade engagement directly affects cut quality and joint accuracy in freshly placed concrete — a worn or incorrectly sized key can cause blade wobble, inconsistent cut depth, or accelerated wear on the surrounding keyway. Replacing a damaged or undersized key with the correct OEM part restores the solid mechanical connection the machine depends on.
