We have just got our new Bronze Floating Bush in.
It's a special run that works specifically with properly matched Carrillo rods.
Eliminates the flaking failures that plague the OEM babbitted floating bush, and replaces it with a monolithic bronze bush that is made with new bearing clearances suitable for its thermal expansion behavior.The use of a floating bush is actually a fine idea for a design, but the propensity of the OEM bush to flake off the babbitting material makes it fail early, and so it just isn't a reliable option in its OEM form. The monolithic bronze makes the entire bush out of suitable bush material, eliminating the surface babbitting, so that there is nothing to flake off. This keeps the basic original design, and eliminates the problems of the babbitted coating.
Cuts the cost of a crank rebuild by 1/3 less than with the Alpha roller big end bearing. It's our latest attempt to try to make things more affordable for the Bullet performance enthusiast on a budget.
