What are some features of a remanufactured Kohler engine?

A:

Quick Answer

A remanufactured Kohler engine is completely disassembled, and all of the parts are carefully inspected, cleaned and measured and either replaced or refurbished, depending on the results of the inspection. All of the machined gasket surfaces are milled to proper specifications, and the cylinders are either bored and fitted with oversize pistons and rings or sleeved and fitted with standard pistons and rings.

As part of the remanufacturing process, the engine block is completely stripped down, cleaned in an acid bath and sandblasted. The cylinders are measured, and depending on the amount of wear and type of engine, either bored oversize or fitted with sleeves. Likewise, the crankshaft is cleaned, measured and machined to original specifications.

After the block and crank are refurbished, the motor is assembled. Valves, valve seats and valve guides are machined to specification or replaced. New pistons and rings are installed and new gaskets and seals are used throughout the build. When needed, governors are rebuilt or replaced and final adjustments are made to ensure a properly running, reliable engine.

A properly remanufactured engine is, in many ways, superior to a brand new engine. When an engine has been run to the point of failure, and the block and crank are still reusable, the block is a stable foundation. Engines are constantly expanding and contracting as they heat up and cool down. A new block or crank, freshly cast, could have an unseen flaw that only appears after it has been run several times. A used block has already passed this test. With a properly remanufactured engine, there is less chance of the block warping or developing a fatal crack.
