Putzmeister Spare Parts SLIDING CLUTCH 479488

This sliding clutch 479488 is an original‑equivalent replacement component built for Putzmeister concrete pump transmissions. It engages and disengages drive power within the gearbox, handling frequent shifting under heavy pumping‑site working loads. Precision‑cut internal and external splines guarantee positive meshing with mating gears during operation.

Manufactured from high‑strength alloy steel, the part goes through hardening treatment for wear resistance. Heavy‑duty surface hardness stands up to repeated friction and shock loads common on concrete pumping equipment. Proper heat‑treatment reduces tooth chipping and premature failure in tough field conditions.

Every spline tooth is machined to strict dimensional tolerances. Accurate tooth geometry ensures smooth sliding movement without jamming during gear shifting. Both inner spline bore and outer drive teeth maintain consistent contact surface for reliable power transfer.

This 479488 sliding clutch fits specified Putzmeister concrete pump gearbox assemblies. It is a direct‑fit swap for the worn‑out OEM unit, no extra modification required during installation. Technicians commonly replace this component when noticing shifting difficulty or gear‑slipping symptoms.

Inspect all spline surfaces for scoring and wear before fitting. Lubricate spline areas with proper gearbox oil upon assembly. Use this genuine‑spec spare to restore transmission function and extend service life for your Putzmeister pumping unit.
