Axle shaft assembly, right S06/44137 Hidromek, aftermarket

Axle shaft assembly, right S06/44137 is an aftermarket part for the Hidromek backhoe loaders. According to the product card, this is the right-hand shaft.

The axle shaft carries torque from the differential to the planetary gearbox at the wheel. On steered axles the shaft is split at the knuckle by a universal or constant-velocity joint. Shock loads, sudden grip after wheelspin and overloading can twist the shaft, wear its splines or break it. A broken shaft cuts drive to the wheel and causes further damage in the gearbox.

Specifications

Compatibility

According to the product card, S06/44137 (S06/44081) is the right-hand axle shaft assembly of Hidromek backhoe loaders; the left-hand counterpart is S06/44136. Other parts are in Axle shafts, propshafts and U-joints.

Fitting

For the change, remove the wheel and planetary gearbox and drain the axle oil. Slide the new shaft carefully into place with its splines lubricated with clean axle oil, using a protective sleeve so the splines do not damage the seal lips. Renew the seals and O-rings and top up the axle oil to level. The shaft comes new; check its splines and bearing surfaces before fitting. Also inspect the other shaft in the axle and the universal joint for wear. When the axle shaft is changed, check the splines of the differential side gear and the planetary sun gear too. Shafts on the two sides of an axle may differ in length, so lay the new one beside the old one to compare. Change the axle oil and inspect the metal on the drain plug.
