Application
Suitable for 134 ci (L-134 and F-134) engines in various vehicles. These 0.030" undersize bearings are used when the crankshaft has been ground 0.030" during overhaul to repair damaged or worn bearing surfaces.
Installation notes
Always measure the crankshaft journal surfaces with a micrometre before ordering bearings — do not rely on markings from old bearings. Check bearing clearance with plastigage. Ensure all bearing surfaces are clean and wiped dry before assembly. Note: the front upper bearing shell has an oil hole which must align with the oil passage in the block.
Compatibility
Only suitable for engines where the crankshaft has been ground 0.030" undersize. NOT usable with standard or other undersize crankshaft dimensions. For standard crankshaft size or other undersize dimensions (.010",.020",.040"), separate bearing sets are available.
Historical context
The Willys 134 ci engine was produced in two versions: the L-134 flathead 'Go Devil' (1941-1971) and the later F-134 'Hurricane' with F-head construction (1950-1971). Both engine variants use the same crankshaft bearings.
