★ Replica of original Ordnance part, manufactured to G-503 specifications. Fits all Willys MB and Ford GPW engines with standard L-134 engine block configuration.
Application
Willys MB (1941-1945), Ford GPW (1942-1945), early Willys CJ-2A with chain-driven L-134 engine (up to approx. 1947). Does NOT fit later gear-driven engines.
Installation notes
Mounts onto the four rear studs of the cylinder block. Always use a new gasket (WO-637237 / FM-GPW-6700). Note: the rear engine mount insulator (WO-A-6156) attaches to this plate — check alignment before final assembly. Torque studs according to TM 9-1803A figure 01-12.
Compatibility
Fits all standard MB/GPW L-134 engines. Note: this part differs per engine variant. Check that the stud configuration of your engine block matches. Not interchangeable with later CJ-3A/M38 gear-driven engines (which have different flywheel housing and rear plate).
Historical context
This plate formed part of the standardised L-134 'Go Devil' engine assembly as used in all 640,000+ Willys MB and Ford GPW jeeps produced during WW2. Ford and Willys produced identical versions (only part numbers differ) to guarantee complete interchangeability.
