Cylinders, Chuck housings, Cylinder heads
Cylinders, chuck housings and cylinder heads, along with pistons, make up the basic parts of the hammer.
Cylinder
Usage
The cylinder is the heart of the hammer itself, which is produced using special technology. It has a series of top-quality bores that are used for oil flow, tie rods passage, installation of additional elements, etc. The quality of cylinder manufacturing directly affects the hammer performance and thus the impact energy delivered by the hammer. They are very difficult to copy and mostly only originals appear on the market.
Maintenance
Possible damage to the cylinder most often occurs as a result of the piston rubbing into the cylinder. Therefore, maintenance is the same as described for pistons.
In the case of scraping, the cylinder can be grinded, if the scratches caused by scraping are removed by grinding. Then an oversized piston is also needed - the size of the piston is determined by the new cylinder size and the prescribed tolerance. Standard cylinder seals are used.
Complete failure of the cylinder calls into question the profitability of hammer repair. |

Cylinder head
Usage
The cylinder head is a kind of cylinder cover with sophisticated production technology. It is most often made with a number of additional elements such as main valves, pilot valves, etc. In some versions, the head also serves as a gas chamber. Some versions have a built-in accumulator on the head. Copying is difficult and unprofitable, mostly original cylinder heads are offered.
Maintenance
No special maintenance is specified except for general maintenance of the hammer. Damage to the cylinder head is rare, and if it occurs, it is necessary to replace it with a new head. |
Chuck housing
Usage
The chuck housing or lower hammer part is almost purely a locksmith's part. It combines tool bushes, tool retainers, pins and plugs. They are often copied and can be found as replacement parts.
Maintenance
Maintenance refers to the regular maintenance of the bushings. Chuck housings can crack and sometimes it is possible to weld them as a temporary solution. Sometimes service workshops turn the inner bore of the chuck housing, which is by no means a recommendation, because then you always have to use an oversized bushings. This intervention is done ONLY if there is no other solution with a direct agreement with the client. Replacing a chuck housing with a new one sometimes makes sense financially. |
