Installation and Big Twin Compatibility

This Colony Machine drain plug is specifically engineered for Harley-Davidson Big Twin models from 2000 and newer, including specific 2016-2018 model years. While designed for Big Twins, it's always recommended to confirm your model's OEM part number (60328-98A) to ensure perfect compatibility, especially for non-Big Twin platforms like Sportsters. For proper sealing and to prevent leaks, always use a new crush washer (sold separately) with each installation or fluid change.

Common questions

What OEM part does this Colony Machine drain plug replace?

This oversized magnetic drain plug is designed to replace Harley OEM part 60328-98A. Colony Machine's oversized version provides enhanced magnetic particle collection compared to a standard plug.

Will this drain plug fit my Sportster?

No, this specific drain plug is designed for Big Twin engines. Sportster models typically use a different drain plug, so please check your model year and part requirements before ordering.

Do I need any special gaskets or crush washers for installation?

We strongly recommend using a new crush washer (sold separately) under the drain plug for a proper, leak-free seal. Reusing old crush washers can lead to slow leaks.
