The Knucklehead motor was faithfully replicated by Tedd Cycle, Inc. and released on January 9, 2002; along with the (Linkert carburetor-intake port) OEM-style Pan cylinder heads in three models: The 1948-'54 (plumber manifold); the 1955-'62 (O-Ring manifold); and the 1963-'65 (external oiler) style.
Our shop manual was written for existing "runners"; and for "builders" of Knuckle & Panhead motorcycles using new, replicated parts. Some topics covered in the step-by-step procedures are not in other OEM Harley manuals, or the excellent Clymer's Panhead manual. When another manual suggest, "replacing the clutch hub liner..." we show you how, and the tools and parts necessary.
Read on through the editorials section for more story on where the Replication adventure is headed. The "motorcycle buying and building public" is still asleep about Knuckleheads. They want to see some pioneers go before them and blaze a trail of standards first. However, there are people out there (like Chris Haynes) that are already building cross-modeled "bobbers" with Knucklehead frames and (early army) XA spring forks (or 1949-'59 Glide forks); fitting upswept shotgun exhaust and KH barrel mufflers. Utilizing the interchangeability of a (1936-1964) 28-year parts run, these mix-and-match possibilities allow a builder to create a unique design, while still using replicated Harley-Davidson components.

The knuckle & panhead motors of today benefit from advances in technology. Modern replica knuckle cylinder heads now have the later 1954-1965 O-ring intake manifold, that eliminates the troublesome (leaking) large-hex "plumber nuts" of 1936-1953...
