★ This repair kit is specifically developed for the early L-134 engines with chain drive — a crucial difference compared to the later gear-driven versions.
Application
This kit is exclusively suitable for vehicles with the early L-134 engine with chain-driven camshaft: Willys MB (1941-1945), Ford GPW (1941-1945), Hotchkiss M201, and early production CJ-2A (1946) before Willys switched to gear drive. Please note: this kit does NOT fit later CJ-2A, CJ-3A, CJ-3B, M38 or M38A1 with gear-driven engines.
Installation notes
Before ordering, verify that your engine actually has a chain drive by removing the timing cover. The chain-driven oil pump is not interchangeable with the later gear-driven version. During installation: ensure that the notch at the end of the oil pump engages correctly with the tooth on the distributor shaft.
Compatibility
ONLY for chain-driven L-134 engines. NOT compatible with: gear-driven L-134 engines (late CJ-2A from approx. 1947), F-134 Hurricane engines, M38 (1950-1952), M38A1, CJ-3A, CJ-3B, or later CJ-5/CJ-6. The type of drive (chain vs. gear) is decisive — not the vehicle model.
Historical context
The L-134 Go Devil engine with chain drive was used during WWII in all Willys MB and Ford GPW jeeps, as well as in early post-war production. From 1947, Willys switched to gear drive for improved reliability and ease of maintenance.
