What is an extendo cylinder on a Case backhoe loader?

It controls the telescopic stick on the rear excavator. When extending, it slides the inner part of the stick, increasing reach and digging depth. It is only found on backhoe loaders equipped with this option: check for the presence of a telescopic stick before ordering.

How do I find the reference of a cylinder?

It is usually stamped or engraved on the barrel near a mounting eye, or on the cylinder head. Clean the area before reading it. If the marking is gone, the reference can be found in the machine’s parts catalog from its serial number or, if not, by measuring center distance, stroke, and diameters.

What is another name for a cylinder?

It is also called a hydraulic cylinder, a direct translation of the English term 'cylinder' used in parts catalogs, or a linear actuator in technical documents. On job sites, many operators simply say "piston," although the piston is actually only an internal part of the cylinder.

What are the three common types of cylinders?

Three types are commonly identified. Single-acting cylinders, powered on one side, return by gravity or spring. Double-acting cylinders, powered alternately on both sides, equip nearly all functions on a Case excavator or backhoe loader, from bucket to stabilizers. Telescopic cylinders with nested stages are mainly used for long-stroke buckets.

Do I need a seal kit for a Case 580 G cylinder or a full cylinder?

For a Case 580 G backhoe loader, a seal kit is enough if the rod and barrel are in good condition and the leak is solely due to worn seals. If the rod is scored or the cylinder still leaks after repair, a complete used cylinder matching the original reference will solve the problem for good.
