Short answer
To get the right spare part for a hydraulic breaker first time, the order needs six pieces of information: the breaker’s brand and exact model, its serial number, the part name and code where there is one, photos of the breaker’s nameplate and of the part, the main dimensions taken from the worn part, and the machine and job the breaker works on. With these the supplier identifies the part without guessing; without them every round of emails adds days of downtime. The usual mistake is not buying a part of the wrong quality but ordering the part for a different version of the same model.
The six things the order should contain
Not every part needs all six. For a model-specific set such as a seal kit, brand, model and serial number are often enough; for a bushing or pin whose name or code is unknown, photos and dimensions decide it.
- Brand and model of the breaker: as written on the nameplate, not as it is called on site. The same model name can come in silenced and open-body versions or in different generations, and their parts may not interchange.
- Serial number: it identifies the version. The manufacturer uses it to know which drawing applies.
- Part name and code: the code from the parts manual, or the one marked on the part itself, is worth more than any name, because part names change from country to country and even from workshop to workshop.
- Photos: the breaker’s nameplate, the whole part, the part next to a ruler or tape measure, and the place where it is fitted.
- Dimensions: diameters, length, groove and hole positions. Take them with a caliper on the worn part and say in the order that the part is worn.
- Machine and job: which machine carries the breaker (excavator, backhoe loader, skid steer) and what material it works in. The recommended tool type in particular depends on this.
Where are the nameplate and serial number?
On most breakers the brand, model and serial number are on a plate on the body or the housing. If the plate has been painted over, crushed or lost, check the purchase documents first; invoices and delivery notes carry the model and often the serial number.
Some manufacturers also stamp the serial number somewhere on the body; the breaker’s manual shows where. If there is no record at all, photos of the whole breaker, the tool diameter and length, and the model of the machine it is mounted on narrow down the class. That route is slower, and measuring the part itself becomes essential.
Photograph the nameplate today
On the day the breaker is delivered, photograph its nameplate and file the picture with your parts orders. When the plate is unreadable two years later, hunting for the serial number can take longer than the order itself. We covered which parts are worth keeping on the shelf in the critical spare parts stock guide.
Part names change from country to country
The same part goes by different names in different countries. Spanish-speaking markets are a good example: in Mexico spare parts are "refacciones", in many other countries "repuestos"; a bushing is a "buje" in Mexico and a "casquillo" in Spain; the seal kit is mostly searched as "kit de sellos" in Latin America and "kit de retenes" in Spain. In English too, one workshop’s "front bush" is another’s "lower bushing".
That is why the backbone of the order is not the name but the code, the photo and the dimension. The name is only a description. We collected the English, Turkish and Spanish names of the parts in the glossary.
Original or aftermarket: say so in the order
A part can be supplied as original, aftermarket or remanufactured, and the three do not mean the same price or the same life. State in the order which one you want; if you accept aftermarket, ask for material and hardness information as well.
We explained which makes sense on which part in the original, aftermarket and remanufactured parts guide. In short: where the dimension decides, aftermarket is used comfortably; where material or geometry decides, ask for documentation.
Parts to order together
Ordering together avoids a second shipment and a second stoppage. If the same part fails again within a short time, the problem may lie not in the part but at the start of the damage chain.
- The bushings when the tool is changed: a new tool running in a worn bushing soon picks up the same marks. We covered how the bushing is measured in the bushings guide.
- The retaining pins and lock with the tool: the retainer set fatigues along with the tool. Details in the retainer set guide.
- The seal kit whenever the breaker is opened: once the body is open, closing it on old seals means a second strip-down. We covered which kit is opened when in the service kit and seal kit guide.
- The cylinder’s condition when the piston is changed: the two are assessed together, otherwise the new piston suffers the same damage in the old cylinder. Details in the piston and cylinder guide.

Do and don’t
Do
- Attach a photo of the breaker’s nameplate to the order.
- Measure with a caliper and say that the part is worn.
- Order by code wherever possible and use the name only as a description.
- State clearly whether you want original, aftermarket or remanufactured.
- Put parts that should be changed together in the same order.
Don't
- Do not write the model as it is called on site; write what the nameplate says.
- Do not just ask for "the bushing for that breaker"; versions can differ.
- Do not estimate dimensions by eye or with a ruler.
- Do not compare parts of different quality on price alone.
- Do not order a third part after the same one fails twice without asking why.
