A technician reading the diagram will notice that the tolerances here are tight. If the diagram shows a "Sealing Ring" on the piston, it is a critical component; a crack here results in a loss of impact energy, rendering the "hammer" function useless.
: Features a drive piston , striker piston , and connecting rod that generate the hammering force.
Connects the crank to the piston; essential for the hammering stroke. Rotary Shaft Seals

For contractors and demolition crews, the Hilti TE 17 is more than just a tool; it is a legacy. Known for its robust "all-round" performance in chiseling and drilling, this electro-pneumatic rotary hammer earned a reputation for survivability on job sites that would destroy lesser equipment.
Finding parts for the TE 17 requires a bit of detective work. Your best sources are:
: Consists of a stator and a rotor (armature) cooled by an internal fan.
Protects the internal toothed gears and transmission.
Because the TE 17 has been discontinued for decades, finding an official diagram is not as simple as a quick Google search. Here are the best-known strategies to locate one:
Due to the age of the TE 17, try to source original, new old stock (NOS) or reputable high-quality replacements to maintain the tool’s longevity.
Steel Balls: These sit inside the chuck and lock into the grooves of the SDS bit. If these are worn, your bits may fly out during use. Lubrication and Maintenance
These are the heart of the hammer action. A common repair involves replacing O-rings or the piston itself to restore impact energy.
