Analyzing the Hilti TE 22 parts diagram is essential for identifying wear-prone mechanical components and understanding the tool's pneumatic hammering action. The TE 22 features a robust internal system centered around a crankshaft and piston assembly that converts motor rotation into high-impact hammer energy. Key Features of the TE 22 Parts Diagram The diagram typically categorizes parts into mechanical drive, impact, and housing groups. Notable components include: Impact Mechanism : At the heart of the hammer function are the drive piston (Item 32) , striker piston (Item 33) , and piston pin assembly (Item 34) . These parts are critical for the tool's power and are often the first to require inspection if impact energy drops. Gear Train & Drive : The bevel gear (Item 36) and bevel pinion (Item 35) facilitate the rotary motion. A crankshaft (Item 50) drives the reciprocating movement of the connecting rod (Item 47) and ram (Item 46) . Chuck & Bit Holder : The drill bit holder (Item 38) works with a locking sleeve assembly (Item 42) to secure SDS-plus bits. Sealing & Lubrication : Crucial maintenance items include multiple O-rings (Items 52, 53) and rotary shaft seals (Items 84, 85) that prevent oil leaks and maintain the internal pressure needed for hammering. Electrical Components : The electrical side includes the stator , rotor (armature) , and carbon brush assembly (Item 101) , which are vital for motor longevity. Maintenance & Service Tips Greasing : Regularly apply Hilti tool grease to the chuck and bit ends to reduce friction and heat. Service Kits : For older units like the TE 22, look for comprehensive service kits that include bearings, seals, and carbon brushes to ensure a complete overhaul. Dust Protection : Keep the dust shield on the chuck clean; a damaged sealing lip can allow grit to enter the gearbox, leading to premature gear failure.

The Hilti TE 22 Go to product viewer dialog for this item. is a classic rotary hammer known for its durability. Understanding its parts diagram is essential for maintenance and repairs, such as replacing worn O-rings or carbon brushes. Key Components of the Hilti TE 22 A typical parts diagram for the TE 22 includes several critical systems that work together to provide its signature hammer action: Piston System : Includes the drive piston (73555), striker piston (73554), and ram (70308). These parts are responsible for the electropneumatic impact mechanism that drives the drill bit into tough materials like concrete. Gearing & Drive : Features a bevel pinion (73559), bevel gear (73558), and crankshaft (70146). These translate the motor's rotational energy into the reciprocating motion needed for hammering. Chuck & Holder : The drill bit holder (74240) and locking sleeve assembly (70303) secure the SDS-plus bits during high-impact operation. Electrical System : Consists of the rotor (armature) and stator . The rotor spins within the magnetic field created by the stator to generate mechanical rotation. Seals & Maintenance : Essential O-rings (e.g., 15.08x2.62 or 17x3) prevent grease leakage and maintain the pneumatic seal required for effective hammering. How the Mechanism Works The TE 22 operates using an electropneumatic drive . Motor Rotation : The electric motor spins the rotor. Reciprocating Motion : A connecting rod (70147) and crankshaft (70146) convert this rotation into a back-and-forth stroke. Air Compression : This stroke moves a piston within a cylinder, creating a cushion of air that "throws" the striker forward. Impact : The striker hits the end of the drill bit, providing the high-energy impact necessary for drilling through masonry. Maintenance & Repair Resources If you are looking to repair your TE 22, you can find detailed schematics and service manuals on platforms like Scribd or Elektrotanya . For replacement parts, retailers like ReveR.store offer rotors, chucks, and maintenance kits. Hilti TE22 Spare Parts List | PDF | Screw - Scribd hilti te 22 parts diagram work
Mastering Your Hilti TE 22: A Complete Guide to the Parts Diagram and How It Works When you own a demolition hammer as legendary as the Hilti TE 22 , understanding its anatomy isn't just about maintenance—it’s about safety, efficiency, and extending the life of a precision tool. Whether you are a professional contractor or a serious DIY enthusiast, searching for the "Hilti TE 22 parts diagram work" indicates you want more than a simple list of components. You want to understand how each part functions within the system. In this deep-dive guide, we will break down every major assembly, explain how the electro-pneumatic mechanism operates, and show you how to use the official parts diagram for repairs and servicing. Why the Hilti TE 22 Remains an Industry Standard Before we dissect the parts diagram, it’s important to understand the tool itself. The Hilti TE 22 is a light-duty combination hammer (also known as a rotary hammer) designed for drilling anchor holes in concrete, brick, and masonry, as well as light chiseling. Unlike a standard hammer drill, the TE 22 uses an electro-pneumatic (air-cushion) mechanism. This delivers more impact energy per blow with less vibration to the user. However, to keep that mechanism working smoothly, you need to know what is inside. That is where the official parts diagram becomes your roadmap. Navigating the Hilti TE 22 Parts Diagram The official Hilti TE 22 parts diagram is typically exploded—meaning all components are drawn separately but aligned to show how they fit together. The diagram is usually divided into five key functional groups:
Housing & Handle Assembly Motor & Electrical System Pneumatic Hammering Mechanism Drivetrain & Gearbox Chuck & Tool Locking System
Let's examine each group in detail. 1. Housing & Handle Assembly – The Skeleton In the parts diagram, the housing is usually the first layer. The TE 22 features a two-piece glass-fiber reinforced polyamide housing. Understanding the Hilti TE 22 parts diagram is
Part #1 – Main Housing Half (Left/Right): These encapsulate the motor and gearbox. Look for cracks here frequently, as drops are a common cause of failure. Part #2 – Damped Auxiliary Handle: Unlike rigid handles, the TE 22 uses a vibration-damped side handle. The diagram shows rubber isolators between the clamp ring and the handle grip. Part #3 – Side Handle Clamping Ring: This steel ring tightens around the neck of the chuck. If your bit rotates while chiseling, this ring is likely loose or worn.
How this works: The housing is not just a shell. It channels cooling air over the motor and provides the structural rigidity needed to transfer impact energy from the hammer mechanism to the drill bit. 2. Motor & Electrical System – The Power Source The TE 22’s heart is a 950-watt universal motor. The parts diagram reveals several critical components:
Part #4 – Armature (complete with fan): A rotating electromagnet. The integrated fan is not a separate part; if the fan blades crack, you replace the entire armature. Part #5 – Field Winding (Stator): Fixed magnets or coils that generate the magnetic field to spin the armature. Part #6 – Carbon Brushes (Pair): These are wear items. The diagram clearly identifies the brush holder caps on the side of the motor housing. When brushes drop below 8mm, performance suffers. Part #7 – Speed Control Switch (Triac Board): A small circuit board connected to the trigger. It regulates power to the motor. Part #8 – Trigger Switch Mechanism: Includes the trigger lever and the return spring. Key Components of the Hilti TE 22 The
How this works: When you pull the trigger, the switch sends current through the brushes to the armature. The armature spins. Simultaneously, cooling air is drawn across the field windings via the fan. If the motor runs but the hammer doesn't, the problem lies downstream. 3. Pneumatic Hammering Mechanism – The "Work" in "Parts Diagram Work" This is the most critical section for anyone searching "Hilti TE 22 parts diagram work" because this is where the hammering action actually happens. The diagram shows an enclosed cylinder:
Part #9 – Piston (Drive Piston): Connected to the crankshaft via a connecting rod. It moves back and forth inside the cylinder. Part #10 – Air Cushion (Sealed volume): Not a physical part, but an integral space between the piston and the striker. The diagram will note the seals that maintain this air cushion. Part #11 – Striker (Impact Piston): A freely moving steel cylinder that transfers energy to the tool bit. Part #12 – O-rings & Sealing Rings: Multiple small rubber rings shown on the diagram. If the hammer loses power but the motor runs fine, these seals are likely worn, allowing the air cushion to leak. Part #13 – Compression Spring: Returns the striker after impact.
