★ Precision component for the iconic L-134 Go Devil engine. Correct offset and oil squirt hole positioning are crucial for reliable operation and optimal lubrication.
Application
For Willys L-134 Go Devil engines. Connecting rods for cylinders 1 and 3 share the same part number (WO-640071) but differ in offset from the connecting rods for cylinders 2 and 4 (WO-640072). Suitable for engines with both chain and gear drive.
Installation notes
Note: the short side of the offset must face towards the nearest main bearing. The oil squirt hole must be fitted on the passenger side (away from camshaft). Connecting rod caps are numbered and must not be interchanged. During overhaul: check for bending, twisting and have machined if necessary by an engine specialist.
Compatibility
NOT interchangeable with connecting rods for cylinders 2 and 4 due to differences in offset. Different versions exist with 7/16" or 3/8" bolts depending on year of manufacture. Ford GPW engines sometimes used connecting rods with integral bolts (cast as one piece with the connecting rod). For gear drive engines: verify that bolt heads have sufficient clearance relative to camshaft lobes.
Historical context
The L-134 Go Devil engine powered the famous WWII jeeps and used two different connecting rod types due to the offset construction of the crankshaft. Part number WO-640071 replaced the earlier WO-639999 from May 1944 with a strengthened version.
