Rehlko 25 041 17-S Product Details

What Is Rehlko 25 041 17-S?

Rehlko 25 041 17-S is an OEM gasket used to seal the connection between the engine exhaust port and the applicable exhaust manifold, header or muffler assembly.

The gasket helps create the proper exhaust seal at the cylinder head and exhaust-system connection.

25 041 17-S Replaces 24 041 49-S

25 041 17-S is the current replacement for older 24 041 49-S exhaust gaskets.

If an older Kohler parts manual specifies 24 041 49-S, current parts catalogs direct replacement to 25 041 17-S.

25 041 17-S Replaces 24 041 02-S

Older engines and equipment catalogs may instead list 24 041 02-S or 24 041 02.

That older exhaust gasket has also been replaced by 25 041 17-S.

What Engines Use 25 041 17-S?

Rehlko/Kohler parts catalogs show 25 041 17-S across many engine families and specifications.

Documented applications include select:

• Command CH18 through CH25 engines
• Command PRO CH620 through CH750 engines
• Command PRO CV-series engines
• Aegis LH640 through LH755 engines
• Courage SV710 through SV-series V-Twin engines

How Many 25 041 17-S Gaskets Are Required?

Many Rehlko/Kohler V-Twin engines use two exhaust manifold gaskets because there is one exhaust connection for each cylinder.

Quantity can vary with the engine and exhaust configuration, so verify the job quantity in the exact parts diagram before ordering.

Related Rehlko Exhaust Parts

Depending on engine specification, related exhaust-system parts may include:

• 25 072 24-S – Metric Exhaust Stud
• 24 072 08-S – M6 x 1.0 x 36 mm Exhaust Stud on applicable engines
• M-841080-S – M8 x 1.25 Flange Nut
• 25 100 52-S – M8 Hex Flange Lock Nut on applicable engines
• Application-specific exhaust manifolds and mufflers

These parts are separately serviced unless a specific exhaust or muffler kit states otherwise.

When Should an Exhaust Manifold Gasket Be Replaced?

Inspect the exhaust gasket whenever the manifold, header or muffler connection is removed.

Replacement may be appropriate when the existing gasket is burned, crushed, cracked, damaged or no longer provides a proper exhaust seal.

Exhaust leakage can also result from loose or damaged mounting hardware, warped mating surfaces, cracked exhaust components or other problems, so the complete exhaust connection should be inspected during service.

Before Ordering Rehlko 25 041 17-S

• Locate the complete Rehlko/Kohler engine model and specification.
• Check the exhaust-system diagram for that exact engine.
• Confirm 25 041 17-S or older 24 041 49-S / 24 041 02-S.
• Verify the required quantity; many V-Twin applications use two.
• Inspect the exhaust studs and mounting nuts during service.
• Do not substitute another exhaust gasket based only on appearance.
