Planetary hub carrier 66855 Carraro, aftermarket

Planetary hub carrier 66855 is an aftermarket part for the backhoe loaders with Carraro axles. This part is the body of the planetary hub carrier.

The planetary gearbox gives an extra reduction at the wheel, relieving the axle shaft and differential, so the hub carrier is one of the most heavily loaded parts of the axle. Carrier wear usually shows as play in the planet pin bores and an oil leak at the wheel. Changing the planetary oil regularly extends the life of the gears and carrier. When the carrier is changed, check the planet pins too.

Compatibility

According to the product card, Carraro 66855 is a planetary hub carrier cover; cross numbers: VOE11709500, CA0066855. 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.
