The Hilti TE 22 is a legacy electro-pneumatic rotary hammer widely used in light to medium concrete drilling and chiseling. Effective maintenance and repair of this tool depend heavily on accurate interpretation of its parts diagram. This paper provides a detailed analysis of the Hilti TE 22 exploded-view diagram, identifies major component groups (drive train, hammering mechanism, switch assembly, and housing), and explains how technicians use the diagram for troubleshooting, ordering spare parts, and performing step-by-step repairs. The paper also discusses common failure points and presents a workflow for diagram-based repair work. The goal is to bridge the gap between theoretical part identification and hands-on servicing.
Modern technicians use:
For the TE 22, PDF manuals remain the most accessible.
A parts diagram, often referred to as an exploded view, is a technical drawing that displays every component of a machine separately but in relation to each other. Instead of a picture of the fully assembled tool, the diagram "explodes" the tool outward, visually separating the housing, motor, piston, gears, and switches. Each part is assigned a specific number, known as a "callout," which corresponds to a reference list on the side of the diagram.
Always use genuine Hilti parts for the TE 22. Aftermarket parts may seem cheaper, but they often fail faster — and the parts diagram won't match exactly.

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.

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
