This Colony timing plug is designed for Harley-Davidson engines using a 5/8-18 threaded timing hole.

The plug seals the timing inspection port and is a parkerized, flanged hex style duplicate of the original factory part. Proper sealing of the timing hole is important to prevent oil leakage while maintaining correct engine appearance on early Harley models.

Designed for Harley-Davidson models from 1931 through 1938 with a 5/8-18 thread timing hole, this plug is also commonly used as a transmission fill plug on 45 cubic inch models through 1940.

This part replaces Harley-Davidson OEM 2326-26. Manufactured in Ohio, USA by Colony. At Boomers Bike Shop, we stock small but critical hardware that fits correctly and belongs on real vintage Harley-Davidson motorcycles.

Fits Harley-Davidson Models:

All models: 1931–1938 with 5/8-18 timing hole

45 models: Transmission fill use through 1940

⚠️ Verify thread size before installation.
