Planetary hub carrier 4475.305.113 ZF, aftermarket

Planetary hub carrier 4475.305.113 is an aftermarket part for the backhoe loaders with ZF axles. This part is the body of the planetary hub carrier.

The planetary hub carrier is the outer part of the final reduction (planetary gearbox) at the axle end: it carries the planet gears and the wheel studs and passes the axle shaft's torque to the wheel at reduced speed. Because it takes heavy loads and shocks, the stud holes, planet pin bores and seal faces can wear or crack over time. A damaged carrier causes oil leaks, misalignment of the planet gears and loose wheel studs. Scratches on the carrier's gasket face cause oil leaks.

Specifications

Compatibility

According to the product card, ZF 4475.305.113 is a planetary hub carrier cover; cross numbers: 130-7027. Fit is confirmed by the axle or transmission type. Other parts are in Carraro.

Fitting

For the change, remove the wheel and drain the planetary gearbox oil. Renew the gasket or O-ring between the carrier and the axle casing and tighten the bolts to the specified torque in a cross pattern. Fill the planetary with oil of the type and quantity in the service manual; after refitting the wheel, torque the nuts and check them again after a short period of work. The part comes new; before fitting, check the planet pin bores, stud holes and gasket face. After the carrier is fitted, turn the wheel by hand to confirm the planetary turns without binding, then check the oil level at the plug hole with the wheel in the position the manual specifies.
