Axle breather 104988 Carraro, aftermarket

Axle breather 104988 is an aftermarket part for the backhoe loaders with Carraro axles.

The axle breather equalises the pressure difference created as the axle heats up and cools down in use. If the breather blocks, pressure builds inside the axle and oil is pushed out past the seals, after which water and dust can be drawn in. On an axle with leaking seals the breather is one of the first parts to check. It sits at the top of the axle casing and is easily clogged when working in mud. In winter a frozen breather can also cause pressure to build in the axle.

Specifications

Compatibility

Fitting

Clean around the old breather before removing it. Screw in the new one by hand and tighten it to the specified torque, taking care not to overtighten plastic-bodied breathers. After fitting, check the axle oil level and look for leaks at the seals. The breather comes new. If the axle is overfilled, oil can escape through the breather, so the axle is never filled above the level in the service manual. Fit the breather with its opening facing up and protected from mud splash. On axles with leaking seals, check the seals again after the breather is changed, and renew any seals damaged by the pressure. When washing the axle, do not aim the pressure washer directly at the breather, or water may get inside.
