Slew cylinder barrel 1346044C1 Case, aftermarket

Slew cylinder barrel 1346044C1 is an aftermarket part for the Case backhoe loaders.

In a cylinder repair the barrel is one of the most expensive and most stressed parts: its bore works constantly under pressure against the piston seal, while the outside is exposed to stones and knocks. Dirty oil leaves lengthwise score marks in the bore, which make the cylinder leak past at one position and the load slowly sink. In a dented or bent barrel the piston jams and the seals tear. With a new barrel, a seal kit and, if needed, a new piston and gland, the cylinder is brought back close to factory condition. After the repair, run the cylinder through its full stroke and check it for external and internal leaks. Score marks in the bore often start with a worn wiper seal in the gland: dust and sand that get inside scratch the barrel along with the piston seal. That is why the wiper is always renewed during the repair. Choose the barrel by part number and compare it with the old one.

Specifications

Compatibility

The barrel belongs to the slew cylinder that swings the backhoe; the photo shows its threaded end. Other parts are in JCB hydraulic cylinders.

Fitting

Watch the cylinder and its joints for leaks during the first hours of work after the repair. On first start, move the cylinder slowly and check the gland and pipe joints for leaks, then run it through its full stroke several times at normal speed.
