  • Exclusively for chain-driven camshaft
  • For L-134 Go Devil flathead engine
  • 4 bolts required per engine
  • Not suitable for gear-driven engines

★ Critical engine component — note: only suitable for early L-134 engines with chain drive. Later engines with gear drive require different mounting method.

Installation notes

Important: this bolt is ONLY suitable for L-134 engines with chain-driven camshaft. Engines with gear-driven camshaft use a different mounting method. Please verify before ordering whether your engine has chain or gear drive.

Compatibility

ONLY for chain-driven camshaft. Willys MB/GPW and M201 were produced with both systems — early versions had chain drive, later models gear drive. This bolt does NOT fit gear-driven engines.

Historical context

The early L-134 Go Devil used a timing chain for camshaft drive. Later production switched to direct gear drive for improved reliability and ease of maintenance.
