9SS25335 - Lincoln Electric Choke Bushing for Ranger 225 - S25335

Maintain OEM Performance on Lincoln Welders

Professional welders and equipment repair technicians know that the longevity of an engine-driven welder like the Lincoln Ranger 225 depends on regular maintenance of both the engine and the chassis components. The 9SS25335 Choke Control Bushing is a vital replacement part for the machine's front panel assembly. It serves as the interface between the operator's choke control knob and the internal carburetor linkage, acting as a bearing surface that reduces friction and prevents metal-on-metal wear.

When a choke bushing fails, it introduces slop into the control system. This mechanical play can prevent the choke plate in the carburetor from closing completely during starting attempts, leading to hard starts in cold weather. Conversely, if the bushing is broken and jamming the linkage, the choke may remain partially applied while welding, leading to carbon fouling of the spark plugs, increased fuel consumption, and poor engine performance. This replacement bushing is manufactured from industrial-grade polymer designed to withstand the thermal cycling and high-frequency vibration inherent to generator/welder operation.

Key Technical Benefits:

• Precision Fit: Molded to the exact diameter required for the Ranger 225 control panel cutout, ensuring a tight seal that prevents dust and moisture ingress around the control rod.
• Self-Lubricating Material: The material composition minimizes friction, allowing for smooth push-pull operation of the choke without the need for external grease which attracts dirt.
• Vibration Damping: Helps isolate the control knob from engine vibration, preventing rattle and reducing operator fatigue during adjustments.

Welders Supply provides this part to ensure your fleet remains operational. Installation is typically straightforward, requiring access to the rear of the front control panel. Once installed, the 9SS25335 restores the tactile feedback of the choke control, confirming to the operator that the choke is fully engaged or disengaged. It is an essential item to keep in your preventative maintenance kit for Lincoln engine drives.
