Product Description
Kohler 24 523 172 – CH740 Genuine OEM Long Block Assembly
The Kohler 24 523 172 is a genuine OEM CH740 long block service assembly designed for professional engine rebuilds and major internal repairs. This factory-assembled long block provides the core engine structure for Kohler Command PRO CH740 engines while allowing reuse of external components from the original engine.
Manufactured to Kohler’s original production tolerances, this long block restores proper compression, crankshaft integrity, and internal durability without replacing carburetor, ignition, charging components, or external accessories. It is ideal for commercial equipment owners or repair facilities performing complete internal engine restoration.
This is not a complete engine — it is a service long block assembly.

Replacement Fitment / Compatibility
Because this is a core block assembly, correct fitment should be verified with your equipment’s existing engine model and parts manual. A long block usually fits units originally equipped with a CH740 engine in the corresponding spec range — but confirm mounting points, PTO shaft dimensions, and accessory bolt patterns before purchase.
