Clutch plate kit 149306 Carraro, aftermarket

Clutch plate kit 149306 is an aftermarket part for the backhoe loaders with Carraro axles. This kit contains the plates of a transmission clutch pack.

In Powershift and shuttle transmissions the clutch packs are made of friction plates stacked alternately with steel counter plates, and when a hydraulic piston squeezes the pack the gear or direction engages. Worn plates cause clutch slip, late gear changes, overheated transmission oil and a burning smell. The life of a clutch pack depends on the cleanliness of the transmission oil and on the operator stopping the machine before changing direction.

Fitting

Soak new friction plates in clean transmission oil before fitting. Stack the plates in their original order and check the pack clearance against the service manual. After assembly, fill the transmission with the specified oil and test the gear changes under light load. The plates come new and are stored in their packaging in a dry, clean place. Before fitting, check that they are flat, their teeth free of burrs and the friction surface undamaged. Inspect the clutch piston, return springs and the slots in the clutch drum the plates slide in, since stepped slots stop the plates moving freely and make the clutch drag. After the repair, measure the transmission pressures to the service manual.
