Application
This pulley is developed for jeeps with 24 volt electrical systems. Originally fitted to M38, M38A1 and M170 military jeeps (1950-1966) and Hotchkiss M201 24V models (1960-1966). Fits both the L-134 flathead engine and the F-134 overhead valve engine. The double groove accommodates two narrow V-belts connecting the crankshaft to water pump and generator/alternator.
Installation notes
During installation: the pulley is secured with the crankshaft bolt and lock nut. Check alignment with water pump and generator/alternator pulley. Both grooves are designed for narrow V-belts (not for wide civilian belts). Note: some reproductions require slight adjustment of the centre bore for optimal fitting on the crankshaft.
Compatibility
PLEASE NOTE: This is the 24 volt configuration with double groove for narrow belts. NOT suitable for standard 6V MB/GPW, CJ-2A or civilian jeeps using single wide pulleys. The 24V systems (M38/M38A1/M201-24V) have a different pulley configuration than 6V vehicles. Check your electrical system (6V or 24V) before ordering.
Historical context
The 24 volt configuration was introduced by the U.S. Army on the M38 (1950) and M38A1 (1952-1966) to provide more reliable electrical performance under demanding military conditions. The Hotchkiss M201 24V was produced from 1960 for the French Army.
