Description
Overview:
This crankshaft is a replacement engine component for the Husqvarna K650 Cut-n-Break disc cutter, supplied to restore smooth and reliable running where the original shaft is worn or damaged. Built from precision‐machined, high‐grade steel, it converts the piston's reciprocating movement into rotation to drive the clutch and blade system. Correct crankshaft geometry is critical to engine balance, sealing, and durability, especially in high‐revving two‐stroke cutters such as the K650 Cut‐n‐Break. The shaft is engineered for accurate fitment with the model's standard bearings, seals, and flywheel components, helping maintain performance and minimise vibration. Part reference 506 35 10 01 assists with identification when matching against manuals or parts diagrams for the K650 Cut‐n‐Break used on site work, kerb cutting, masonry, and general construction tasks.
