Important Notes

• Verify Kohler part number 25 153 24-S before ordering

• This listing is for a replacement engine O-ring, not a complete engine assembly or sealing kit

• Confirm compatibility with your specific Kohler engine model and specification number

• Verify the engine identification information before purchasing

• Do not assume compatibility with all Kohler engines or lawn and garden equipment

• Different Kohler engine configurations may require different O-ring sizes, materials, or sealing designs

• The equipment model alone may not identify the correct replacement O-ring

• Check the engine manufacturer's illustrated parts diagram for the correct replacement component

• Confirm the original O-ring's dimensions, cross-sectional thickness, and installation location

• Similar-looking O-rings may differ in size, material composition, temperature resistance, or intended application

• Verify that the replacement O-ring matches the designated engine sealing surfaces

• Confirm compatibility with the existing engine housing, mating components, and sealing groove

• Do not substitute an incorrectly sized O-ring that may prevent proper sealing

• Verify whether the application requires additional gaskets, seals, or retaining components

• Do not assume mounting hardware, lubricants, or additional sealing components are included

• Confirm whether the manufacturer requires a specific O-ring installation procedure

• Follow the engine manufacturer's recommended maintenance and sealing system repair procedures

• Replace O-rings that are cracked, cut, flattened, hardened, swollen, or otherwise unsuitable for reuse

• Do not reuse a damaged O-ring during engine component reassembly

• Shut off the engine and allow it to cool sufficiently before performing maintenance

• Remove the ignition key and secure the equipment against unintended starting

• Disconnect the spark plug wire or applicable ignition connection when instructed by the manufacturer

• Wear appropriate protective gloves and eye protection during engine repairs

• Inspect the O-ring installation groove and surrounding mating surfaces for damage or excessive wear

• Check sealing surfaces for corrosion, scratches, contamination, or remaining sealing material

• Carefully remove the existing O-ring without damaging the sealing groove or adjacent components

• Clean the designated O-ring mounting area before installing the replacement component

• Prevent dirt, debris, and foreign materials from entering internal engine passages during maintenance

• Verify that the replacement O-ring is correctly positioned within the designated sealing groove

• Do not stretch, twist, pinch, or excessively compress the O-ring during installation

• Use only manufacturer-approved lubricants or installation aids when specified

• Do not apply gasket sealant or adhesive unless specifically recommended by the engine manufacturer

• Confirm that the replacement O-ring remains properly seated during engine component reassembly

• Do not force components together if the O-ring appears misaligned or improperly positioned

• Use manufacturer-approved replacement fasteners where required

• Tighten associated mounting hardware according to the engine manufacturer's specified torque requirements

• Avoid overtightening, which may damage sealing surfaces or distort mating components

• Ensure all related engine components are securely installed before operation

• Inspect the repaired sealing location for signs of leakage after installation

• Verify proper engine operation according to manufacturer instructions after completing repairs

• A replacement O-ring may not resolve leakage caused by cracked housings, damaged sealing grooves, warped mating surfaces, or unrelated component failures

• Follow the manufacturer's maintenance and safety recommendations

• Confirm current manufacturer specifications, engine compatibility, and included quantity before ordering
