The Hilti TE 17, while a vintage workhorse, remains a favorite for DIYers and collectors due to its legendary build quality. If you are attempting a restoration or repair, finding a reliable parts diagram is the single most important step to success. The "Hilti TE 17 Parts Diagram" Review
The parts diagram for the TE 17 is generally found within the original service manuals or through specialized vintage tool archives. Here is a breakdown of why this resource is indispensable: Exploded Views for Reassembly:
The TE 17 has a complex electropneumatic internal structure. The exploded view diagrams are essential for seeing how the piston, hammer, and strike pins align. Without this, reassembling the gear housing is nearly impossible. Precise Part Identification:
Many internal seals and O-rings look similar but have distinct tolerances. A good diagram provides the official Hilti part numbers, which is vital when scouring eBay or specialty retailers for "new old stock" (NOS) components. Lubrication Points:
Most high-quality diagrams also highlight specific lubrication zones. For a tool this old, knowing exactly where to apply fresh Hilti-grade grease—and where
to—is the difference between a working drill and a burnt-out motor. Troubleshooting Guide:
These diagrams often accompany troubleshooting charts that link specific symptoms (like "weak hammering") to specific internal parts, such as a worn-out ram or damaged compression rings. Prefeitura de Aracaju Where to Find the Diagram Service Manual Archives:
Comprehensive PDFs are often hosted on technical resource sites or municipal archive portals like the Hilti TE 17 Service Manual

Mastering the Hilti TE 17: A Complete Guide to Parts and Maintenance
The Hilti TE 17 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.
If you are looking for a Hilti TE 17 parts diagram, you likely have a tool that has stood the test of time but finally needs a little TLC. This guide breaks down the essential components and maintenance tips to keep your vintage powerhouse running. Why You Need a Parts Diagram hilti te 17 parts diagram
The TE 17 is built like a tank, but it’s an intricate machine. A schematic is vital for:
Correct Reassembly: Ensuring the striking mechanism and gears are timed correctly.
Part Identification: Pinpointing exactly which seal or carbon brush has worn out.
Oil Specifications: Understanding the sealed lubrication system. Key Components of the Hilti TE 17 1. The Carbon Brushes (Motor Assembly)
If your drill is sparking excessively or failing to start, the carbon brushes are the first place to look. These are "wear parts" designed to be replaced. Most diagrams will show them located near the rear of the motor housing. 2. The Chuck (Tool Holder)
The TE 17 uses the classic Hilti "TE-C" connection (now commonly known as SDS-Plus). The chuck assembly consists of:
Dust Shield: Prevents debris from entering the internal mechanism.
Locking Balls/Sliding Sleeve: The mechanism that holds the drill bit in place. 3. The Piston and Striking Mechanism
This is the heart of the electro-pneumatic system. The diagram will reveal a piston that compresses air to drive a "striker" against the drill bit. Over time, the O-rings on the piston can flatten, leading to a loss of hammering power. 4. The Gearbox and Lubrication
Unlike modern tools that use grease, the TE 17 famously uses a specific weight of gear oil. The parts diagram will show the fill plug and the gaskets required to keep the unit oil-tight.
Pro Tip: Never overfill the oil reservoir. It needs a small "air cushion" to function correctly. Common Maintenance Issues
Leaking Oil: Usually caused by a degraded felt seal or a worn O-ring at the chuck.
No Hammering Action: This often indicates the internal piston seals have dried out or the oil level is too low. The Hilti TE 17, while a vintage workhorse,
Loss of Power: Check the cord for frays and the brushes for wear. How to Use the Diagram for Repairs
When looking at a schematic, pay close attention to the exploded view numbers. These numbers correspond to the manufacturer's part numbers. While Hilti no longer stocks all original parts for the TE 17, many specialized vintage tool vendors and aftermarket manufacturers provide high-quality replacements for seals, brushes, and cords. Conclusion
The Hilti TE 17 isn't just a tool; it's a piece of industrial history. By using a proper parts diagram and performing regular maintenance, you can ensure this rotary hammer continues to drill through concrete for another generation.

The TE 17 is a purely mechanical machine without modern electronics, making its internal structure relatively straightforward. Motor Assembly: Includes the (stationary magnetic field) and rotor/armature (rotating component). Piston System: Features a drive piston striker piston , and a connecting rod. Transmission: bevel pinion bevel gear to translate motor power to the drill holder.
Comprised of a cast gear housing and a motor housing with an endcap. Seals & Bearings: Common wear items include (sizes like 33x3 and 8x2) and various ball bearings (e.g., 6004, 6001, 627). ReveR.store 📂 Where to Find Diagrams
Since Hilti no longer provides these directly on their modern website, you can use these resources: Instruction Manuals: Sites like ManualsLib
host the original German "Bedienungsanleitung," which often contains basic assembly illustrations. Technical Forums: Woodwork Forums
have shared scanned pages of the original 12-page brochure and exploded views included in renovation kits. Specialty Suppliers: Sites like ReveR.store Profibohrer
provide parts lists and visual references for replacement components like carbon brushes, seals, and rotors. ReveR.store 💡 Maintenance Tips Oil Capacity: The TE 17 requires 40 milliliters
of Hilti-specific oil for proper lubrication of the gear and piston system. Function Switching: Left and right housing shells – Contain pre-cast
To switch between hammer-drilling and rotation-only, you must rotate and shove the rubber-clad bajonet forward to decouple the hammering mechanism. Repair Kits:
Many vintage enthusiasts recommend buying a full "maintenance/service kit," which typically includes the necessary O-rings, bearings, and grease in one package.

The Hilti TE 17 Go to product viewer dialog for this item. is a vintage rotary hammer that pioneered the patented bajonet drill coupler, which allows for quick, tool-free bit changes. Because this model is older, its internal mechanics rely on a unique oil-lubrication system rather than standard grease, making detailed exploded diagrams essential for preventing leaks that could ruin the motor. Key Internal Components
A typical service diagram for the TE 17 includes several critical groups of parts:
Motor Assembly: Consists of a stator and a rotor (armature) cooled by an internal fan.
Pneumatic Hammering System: Features a drive piston, striker piston, and connecting rod that generate the hammering force.
Transmission & Gears: Includes toothed gears, bevel pinions, and clutch groups that manage speed and torque.
Sealing Elements: Critical O-rings and rotary shaft seals keep oil inside the gear housing and out of the motor. Common Replacement Parts

The gray, fiberglass-reinforced polyamide housing is the skeleton. Key components in this section of the parts diagram include:
Diagram insight: Look for callout #3-7 in the schematic – this identifies the integrated switch lock button, a common failure point.
Moving forward in the diagram, you encounter the mechanical transfer of power. The Gearing Group is where the high RPM of the motor is converted into the torque needed for drilling.
The schematic details the Grease Chamber, which houses the primary pinion and the main gear. For anyone attempting a repair, this section of the diagram is crucial for ordering the correct seals and gaskets. A common failure in older TE 17s is grease leakage; the parts diagram identifies the exact O-rings needed to reseal the housing, preventing the catastrophic lubrication loss that kills gears.
