Overview

The Kohler 24 523 155 is the genuine long block for Kohler Command PRO EFI ECV630–ECV650 vertical-shaft engines. A long block replaces the core of a worn or damaged engine while you keep the external components from your original engine, which is often the fastest way to get a mower back to work. Kohler Engines now operates under the Rehlko name; the part number is unchanged.

Frequently asked questions

Which engines does the 24 523 155 long block fit?

Kohler catalogs it as the ECV630–ECV650 long block for Command PRO EFI vertical-shaft engines. Give us your engine model, spec and serial number and we will confirm it is the correct block.

What is a long block?

A long block is the core engine assembly that replaces the worn internal section of the engine. External components such as the fuel system, electrical parts and shrouds are typically moved over from your old engine; ask us if you need a list for your spec.

Does this fit ECV730–ECV749 engines?

No. Kohler uses a different long block number for that range (for example 24 523 16 for ECV730–ECV749). Match the long block to your engine's model and spec.

Is this a genuine Kohler part?

Yes. 24 523 155 is the original Kohler/Rehlko service number, not a rebuilt or aftermarket block.

Is Kohler the same as Rehlko?

Yes. Kohler's engine business now operates as Rehlko, and Kohler part numbers such as 24 523 155 are unchanged.

Where do I find my Kohler engine model and spec number?

Look for the Kohler/Rehlko identification label on the blower housing or valve cover; it lists the model (for example ECV650), the spec number and the serial number.
