Miller Replacement Engine Kohler CH730-3342 Gas Electric Start

Get Your Rig Back Up and Running

When your engine drive goes down, money stops coming in. The Miller 291956 is the exact replacement engine you need to breathe new life into your trusted welder. This isn't a generic motor that requires hours of modification to fit; it is the specific Kohler CH730-3342 gas engine used by Miller, ensuring a drop-in installation. Whether your old engine has thrown a rod or simply reached the end of its high-hour life, swapping it out with this OEM unit is the fastest way to get back to burning rod and generating power.

This beast is built to work as hard as you do. It’s a 23.5 horsepower V-Twin Kohler Command PRO, legendary for its toughness. It features an electric start and a smart E-Choke system, meaning you won't be fighting to get it started on those freezing cold mornings—just turn the key and go. The V-Twin design runs smoother and quieter than older engines, making for a better work environment around the truck. It also handles the sudden load spikes of striking an arc or firing up a grinder without bogging down, giving you the consistent power you need for quality welds.

Don't waste time trying to retrofit a different engine or gambling on a rebuild that might not hold up. This package comes ready to mount, with the correct shaft output and mounting bolt pattern for your Miller machine. It includes the heavy-duty features you expect, like cast iron cylinder liners and a pressurized oil system with a filter, so it’s ready for another few thousand hours of abuse. Protect your investment and your reputation by sticking with genuine Miller parts that are guaranteed to perform.
