★ Correct reproduction of the early timing chain cover for authentic restoration of WWII and early post-war military jeeps.
Application
Suitable for Willys MB and Ford GPW (1941-1945) with L-134 Go Devil engine with chain drive (casting 638632, up to engine serial number approx. 44417). Also applicable to early Hotchkiss M201 vehicles still fitted with chain drive. Note: later L-134 engines used gear drive and require a different type of cover.
Installation notes
Check before fitting that your engine has chain drive (not gear drive). Always replace the crankshaft gear oil seal when fitting a new cover. Ensure correct alignment with oil sump — use new gasket and correct torque for bolted connections. Camshaft thrust plunger stud must be correctly positioned.
Compatibility
Exclusively for L-134 engines with CHAIN DRIVE. Not compatible with later L-134 or F-134 engines with gear drive. Early WWII MB/GPW and first CJ-2A production up to engine serial number approx. 44417 had chain drive. Hotchkiss M201 received gear drive from production onwards in most cases — check your specific engine. The two systems are not interchangeable without major modifications.
Historical context
The Willys L-134 Go Devil was produced during WWII with chain drive for the camshaft. After the war, Willys switched to the more reliable gear drive, which marks the distinction between early and late engines.
