The internal "work" of the TE 22 is driven by a complex mechanical and electrical assembly. High-wear items frequently identified in parts lists include: Piston Assembly : Includes the drive piston (73555) striker piston (73554) , which generate the hammering action. Gears and Pinions : The mechanical rotation is handled by the bevel gear (73558) bevel pinion (73559) Electrical System : Standard repairs often require replacing the carbon brushes (73579) Seals and O-Rings : To maintain internal pressure and lubrication, various O-rings (70425, 70400) rotary shaft seals (70449) are critical.
