Big end bearing problem was solved !!!

After many years with troubles of big end connecting rod bearings we solved problem with new type bearing.

New bearings are machined from solid spring bronze material on CNC machine. Phosphor bronze material has good toughness, strength, good sliding properties. One side of bearing is rounded to fit crank disc radius corner.

Bearings were tested on our Dyno tester about 1 hour in full load (about 80L of Methanol). We dismantled crankshaft and all parts look as new. No coloured on hub pins, no wear on shafts and big end conrod bores.
