★ This timing gear is designed for the Willys 134ci four-cylinder engines equipped with gear drive instead of the earlier chain drive. An essential component during engine maintenance and overhaul.
Application
This camshaft timing gear is developed for Willys jeeps with 134ci (L-134 or F-134) engine fitted with gear-driven camshaft. The transition from chain to gear drive took place from mid-1946 (engine number 44417). Note: early MB/GPW and very early CJ-2A engines (before 1946) use chain drive and require different components.
Installation notes
Check before installation whether your engine has gear or chain drive — this is a critical difference. When replacing: set timing correctly using the marked teeth on crankshaft and camshaft gears. A gear puller may be required during removal. Older fibre gears may have become brittle and break during removal.
Compatibility
ONLY for engines with gear drive (gear-driven). NOT compatible with chain drive (chain-driven) as used in early MB, GPW and early CJ-2A engines until mid-1946. The L-134 engine was supplied during some periods with both chain and gear drive — always check your engine number and original specification. F-134 engines almost always use gear drive.
Historical context
Willys-Overland switched in July 1946 from chain drive to gear drive for the L-134 camshaft. This modification brought greater reliability and simpler maintenance. Originally fibre gears were used, but modern replacements are often metal for longer service life.
