Hilti Te 17 Parts Diagram 【UHD】

When your trusted drill finally needs maintenance, finding an accurate is your first step toward a successful repair. This comprehensive guide breaks down the anatomy of the TE 17, explains its core mechanical systems, and provides step-by-step instructions for sourcing parts and rebuilding your tool. Why You Need a Hilti TE 17 Parts Diagram

The diagram shows the chuck in an exploded “stacked” order. When reassembling, the balls must seat into specific detents. Missing a single ball means bits will not lock.

The Hilti TE 17 is a legendary rotary hammer drill known for its durability and "pumping" pneumatic action. Even though it is a vintage tool, many professionals and DIY enthusiasts continue to maintain these machines because of their robust build quality. Finding a clear Hilti TE 17 parts diagram is the first step in successful maintenance or repair.

The is a legendary piece of engineering. As the world’s first electro-pneumatic rotary hammer drill, it revolutionized the construction industry when it debuted in the 1960s. Even decades later, these "red tools" are still found in workshops and on jobsites, prized for their durability and classic mechanical design.

Often sold in sets, these are high-wear items that frequently need replacement to keep the motor running. hilti te 17 parts diagram

Note how the drive gear on the armature meshes with the large gear on the crankshaft. When reassembling, these parts must line up precisely according to the diagram layout to avoid snapping teeth upon startup. Tips for Sourcing Replacement Parts

Need help finding a specific part number? If you can provide the or year of manufacture from your tool, I can help you find a more specific, exploded view diagram.

Officially, Hilti does not publish these diagrams publicly. They have historically been reserved for their own authorized service centers and often shared only by request. That said, there are a few crucial internal systems that owners frequently need to understand.

Pro tip : If the tool sparks excessively at the brushes, examine the commutator. If grooved more than 0.5mm, replace the entire armature. When your trusted drill finally needs maintenance, finding

Fits the TE 17 for secure bit retention.

| Part Category | Specific Part | Description & Common Issues | | :--- | :--- | :--- | | | Chuck (Bit Holder) | The component that holds the drill bit. The TE 17 exists in two versions: older models with a "twist-type" chuck (insert bit and twist), and newer versions with a "pull-back" chuck. This part is prone to wear and frequently needs replacement. | | | Bayonet Assembly | The interlocking mechanism connecting the chuck to the tool's body. This can be a complex area to disassemble, and owners have noted that it does not use a standard circlip like other brands, making replacement tricky. | | Motor & Drive | Armature | The rotating part of the electric motor. In the TE 17, the armature rode on a porous, oil-impregnated bearing (an "oilite bushing"), which is a known wear point that can cause the armature to rub against the stationary field windings. | | | Carbon Brushes | These transfer electricity to the spinning armature. They are a standard wear item that should be checked and replaced periodically when worn down (typically below 5mm). | | | Field | The stationary part of the motor that provides the magnetic field. It can be damaged if the armature fails. | | Lubrication System | Gear Housing | The sealed compartment for the gear train. | | | Gear Oil | The TE 17 does not use grease but requires a specific amount of gear oil to lubricate its internal components. Owners recommend using about 30-50cc of a light-bodied gear oil and replacing it every few years of use. | | | Fill Cap | A cap on top of the gear housing. A black cap indicates the model lacks a safety slip clutch, while a red cap indicates the presence of one. | | Electrical & Controls | Trigger Switch | The on/off switch. This is an electrical component that can fail over time and is a common issue. | | | Power Cord | The external power cable. It should be regularly inspected for cuts or damage and replaced if necessary to prevent electrical hazards. | | Housing & Mechanical | Hammering Mechanism Coupling | A "rubber-clad, studded bayonet" between the drill bit and motor housing. Rotating and sliding this ring forward disengages the hammering action for rotation-only drilling; pulling it back locks rotation and hammering together. The TE 17 does not have a dedicated hammer-only mode. |

The shows a very tight tolerance between the drive piston and impact piston – that air gap is a safety feature. If you incorrectly reassemble the tool without the O-ring or with the wrong piston orientation, the tool can lock up at full speed, shattering the barrel.
