★ This original NOS gear is essential for correct operation of the gear-driven L-134 engine and maintains the authenticity of your restoration.
Application
Suitable for Willys vehicles with late L-134 engine fitted with gear-driven camshaft. The transition from chain to gear drive at Willys occurred from engine serial number 44417 in July 1946. Note: not compatible with early engines (1941-1946) that used chain drive. Always verify your engine's camshaft drive type before ordering.
Installation notes
When replacing, the oil pump drive must also be checked — gear-driven engines rotate the camshaft in the opposite direction to chain-driven engines and require a different oil pump drive gear. Ensure correct timing marks during installation.
Compatibility
NOT compatible with early MB/GPW engines (1941-1945) — these use chain drive with sprocket. Not interchangeable between chain-drive and gear-drive systems without complete conversion of camshaft, crankshaft gear and oil pump.
Historical context
Willys-Overland introduced the gear-driven camshaft in the L-134 engine from mid-1946 as an improvement over the original chain drive from MB/GPW production. This system proved more reliable and became standard on later CJ and M38 vehicles.
