Husqvarna 505316619 Throttle Shaft and Lever

The Husqvarna 505316619 Throttle Shaft and Lever is a genuine OEM component designed for the K650, K700, and K650CutnBreak power cutters. As a direct OEM replacement, this part is manufactured to Husqvarna's exact specifications, ensuring the throttle mechanism operates with the same precision as the original. This assembly fits directly into the handle housing of compatible K-series power cutters, restoring proper throttle actuation without adaptation. DHS Equipment supplies this part to help keep your equipment running at full capacity on the jobsite.

Key Features

• Genuine OEM Throttle Precision — manufactured to Husqvarna's exact tolerances, ensuring consistent throttle travel and accurate engine response specific to K-series power cutter operation.
• Direct-Fit Replacement — engineered to seat correctly within the handle assembly of compatible power cutters, aligning with existing mounting points for a straightforward installation.
• Broad K-Series Compatibility — fits the K650, K700, and K650CutnBreak power cutters, covering a wide range of Husqvarna's professional handheld cutting lineup.
• Restored Throttle Control — a worn or damaged throttle shaft and lever can cause erratic engine speed, sluggish response, or loss of operator control; replacing this assembly restores smooth, predictable power delivery.
• Operator Safety — the throttle shaft and lever are critical to the operator's ability to manage engine speed and reduce power quickly; a fully functional assembly is essential for safe handling of a handheld power cutter.

The Throttle Shaft and Lever assembly forms the mechanical link between the operator's trigger input and the carburetor's throttle butterfly, controlling how much fuel and air the engine receives and therefore its speed and cutting power. When this assembly wears, bends, or breaks, the throttle may stick, respond inconsistently, or fail to return to idle — all of which compromise both cutting performance and safe operation. Replacing part number 505316619 with a genuine OEM unit restores the direct, responsive control that K650, K700, and K650CutnBreak power cutters are built to deliver.
