Application
This oil seal fits Willys L-134 'Go Devil' engines with chain-driven camshaft as used in early Willys MB (1941-1945), Ford GPW (1941-1945), Hotchkiss M201, and early CJ-2A models (1946-early 1947) before the change to gear drive.
Installation notes
Installation is done from the inside into the timing chain cover. First remove the crankshaft pulley and old seal carefully without damaging the cover. Press the new seal in with the lip facing inward. Check before installation that the crankshaft has no sharp edges or grooves that could damage the new seal.
Compatibility
NOTE: This seal is ONLY suitable for engines with chain-driven camshaft. Later CJ-2A (from late 1947), CJ-3A, CJ-3B, M38 and M38A1 have a gear-driven camshaft and use a different timing chain cover with different seal specifications. Check before ordering whether your engine has chain or gear drive.
Historical context
The early L-134 'Go Devil' engines in WWII-production Willys MB and Ford GPW used chain drive for the camshaft. After the war, Willys gradually switched to the more reliable gear drive, making this seal specific to early production vehicles and restorations.
