K2735-1 - Lincoln Electric Kubota Engine Cold Weather Heater Kit

Reliable Engine Performance in Extreme Cold

The Lincoln Electric K2735-1 Cold Weather Kit is a critical accessory for industrial operators working in harsh winter environments. Designed specifically for Lincoln Electric welding power sources equipped with Kubota diesel engines, this kit addresses the fundamental challenges of cold-weather internal combustion. Diesel engines rely on compression ignition, which becomes significantly more difficult as ambient temperatures drop. Cold oil thickens, increasing friction and drag on the starter, while cold cylinder walls sap the heat generated during compression. This kit provides a multi-faceted solution to ensure reliable ignition and smooth operation down to -40`F (-40`C).

The system utilizes two distinct 120V AC heating elements to prepare the engine for service. First, the Engine Block Heater warms the coolant within the engine block, transferring heat to the cylinders and head. This aids in vaporization and combustion of the fuel during cranking. Second, the Oil Pan Heater is attached directly to the oil reservoir. By maintaining the oil at a higher temperature, the heater prevents the lubricant from becoming overly viscous. This ensures that when the engine turns over, oil flows immediately to critical bearings and surfaces, significantly reducing cold-start wear and tear.

In addition to the active heating elements, the kit includes a Radiator Grill Tarp. This passive component is essential during operation in sub-zero temperatures. By restricting airflow through the radiator, the tarp allows the engine to reach and maintain its optimal operating temperature more quickly, preventing 'wet stacking' and ensuring efficient fuel combustion. For maximum performance in arctic conditions, Lincoln Electric recommends utilizing this kit in conjunction with 0W40 synthetic oil and arctic-grade diesel fuel.

Technical Specifications

The K2735-1 is engineered for seamless integration with compatible Kubota power plants found in Lincoln equipment. The heaters require a standard 120V AC power source, typically available from shore power or a secondary generator on-site. The kit comes complete with all necessary mounting hardware and cable ties, ensuring a secure and professional installation that withstands the vibration and rigors of industrial use.
