Application
Fits the vehicles listed in the product categories: Willys MB, Ford GPW, M201, CJ-3A, M38, CJ-3B. Suitable for vehicles with 8-1/2" clutch and 4-134 engine (both L-head and F-head variant). Note: this bearing does NOT fit vehicles with 9-1/4" clutch or 6-cylinder engines.
Installation notes
The bearing is mounted on the clutch carrier (part number 644366) which slides over the gearbox input shaft. For replacement, the gearbox/transfer case must be removed together. During overhaul: always replace the clutch disc, pressure plate as well and have the flywheel skimmed. Ensure correct adjustment of clutch free play (1 inch free pedal travel) after installation.
Compatibility
Note the difference between L-head (early MB/GPW/M201/CJ-2A) and F-head (late CJ-3A/CJ-3B/M38A1/CJ-5) engines — this bearing fits both variants. Do check whether your vehicle has an 8-1/2" or 9-1/4" clutch, this bearing is only for 8-1/2" system. Often sold as a set with clutch carrier and spring, but can also be replaced separately.
Historical context
The clutch release bearing was standard equipment on all WWII jeeps and post-war civilian models with 4-cylinder engine. The construction remained largely unchanged from 1941 to 1971, which explains the mutual interchangeability.
