Kohler / Rehlko engine questions
My engine says Kohler. Can you still help?
Yes. Kohler Engines is now Rehlko. Send the complete model, specification and serial number from your existing label so we can identify the engine.
Can another engine with the same horsepower replace mine?
Horsepower alone does not establish compatibility. The shaft, mounting, controls, electrical connections and equipment application must be checked.
Should I bring the machine or just the engine?
Call first with the equipment details and symptoms. We can discuss access, what to bring and scheduling before you transport the machine or loose engine.
