ZF Gearbox Nut Flange

ZF Gearbox Nut Flange

This genuine ZF slotted nut (M100 x 1.5 thread) is specifically designed to secure the output flange on ZF concrete mixer gearboxes, including the P-5300, P-6300, P-7300, and PK-7500 series. As a critical fastening component in the drum drive system, it ensures the output flange remains tightly seated under the extreme rotational loads of a concrete mixer. Replacing this nut is essential during gearbox rebuilds or when servicing the output flange seals and bearings to maintain proper torque and prevent fluid leaks or mechanical play.
