Features
- 010" undersize bearing set for reground crankshaft
- Complete with front, centre and rear bearing shells
- Suitable for L-134 and F-134 engines
- Both timing chain and gear drive
- High quality precision bearing shells
★ Essential component when overhauling the 134 ci engine. The 0.010" undersize bearings compensate for the standard first grinding step when the crankshaft is reconditioned.
Installation notes
Clean all bearing surfaces thoroughly — no dirt or oil behind the bearing shell. Lubricate bearings with assembly lube before fitting. Main bearing cap torque: 65-75 lb-ft. Check crankshaft rotation at each tightening stage — the crankshaft must turn smoothly without binding. Keep bolts and threads clean and dry for correct torque reading.
Compatibility
Main bearing sizes are not linked to connecting rod bearing sizes — these may differ independently. Crankshafts are ground in standard steps of 0.010". Always check existing bearings (often marked on reverse) or ask the machine shop for the grinding size. Available in multiple sizes: standard,.010,.020,.030,.040 undersize.
Historical context
The 134 ci engine powered both WWII jeeps (MB/GPW, 1941-1945) and later civilian and military models. The robust construction with balanced crankshaft and precision bearing shells ensured reliability in the harshest conditions.
