Application
Specific to the earliest Willys MB slat grill jeeps, chassis numbers MB100001 to approximately MB125809 (November 1941 – March 1942). Later slat grill jeeps and standard MB/GPW models used a different version with vent connection.
Installation notes
Attachment to engine block with gasket. Note: this early-type has no connection for breather hose and no generator clearance – please verify this is the correct version for your chassis number.
Compatibility
ONLY suitable for earliest slat grill MB (approximately MB100001-125000). NOT compatible with later MB, GPW, or CJ models requiring a larger oil filler tube with vent connection. The funnel-type cap is push-on, not twist-off.
Historical context
The very first Willys MB slat grill jeeps had a simpler oil filling system with a small funnel-type tube without venting. This was soon replaced by a larger version with vent connection for improved crankcase ventilation.
