A typical parts diagram for the TE 22 includes several critical systems that work together to provide its signature hammer action: hilti te 22 parts diagram work
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
Troubleshooting and Repair: Making a Hilti TE 22 Parts Diagram Work for You
The Hilti TE 22 rotary hammer is a legendary workhorse known for its durability in demanding masonry and demolition environments. However, even the most robust tools eventually require maintenance. Understanding how to use an exploded parts diagram
is the first step in extending the life of your equipment and performing successful DIY repairs Why You Need a Parts Diagram
A parts diagram acts as a visual roadmap of your tool’s internal anatomy. It helps you: Identify Mystery Parts:
If a small spring or washer falls out during disassembly, the diagram shows exactly where it belongs. Order Correct Replacements: Using the specific item number (e.g., item 32 for the drive piston ) ensures you don't waste money on parts that don't fit. Visualize Assembly:
It illustrates the order and orientation of complex components like the piston pin assembly bevel gears Essential Components of the Hilti TE 22 Hilti TE 22 is a legacy rotary hammer
Based on official service documents, the TE 22 consists of several critical systems that often appear in parts lists: The Hammering Mechanism: This includes the drive piston (item 32), striker piston (item 33), and the (item 46). The Gear Train: Key parts like the bevel pinion (item 35) and toothed gear
(item 37) manage the transfer of power from the motor to the bit. The Tool Holder (Chuck):
This is one of the most commonly replaced assemblies. It includes the locking sleeve Sealing System:
Crucial O-rings, such as the 15.08x2.62 (item 53) and 13.95x2.62 (item 54), prevent grease leakage and maintain the pneumatic seal required for hammering. Common Repair Scenarios Tool Not Hammering:
This is often caused by worn O-rings on the piston or striker. Consult the diagram to find the exact O-ring specifications before ordering. Bit Slippage: If the bit won't stay locked, the chuck assembly locking sleeve
may be worn. Replacing the entire chuck is a common and effective fix. Motor Running but No Movement: This typically points to a failure in the gear train or a snapped connecting rod (item 47). Professional Maintenance Tips Hilti TE22 Spare Parts List | PDF | Screw - Scribd

Chucking System: Comprises the drill bit holder (#38) and the locking sleeve assembly (#42). Common Maintenance & Repair Parts
For a tool of this age, certain parts are more prone to wear and may require replacement to keep the unit operational:
Carbon Brushes: Critical for electrical contact in the motor; sets can be found through specialized retailers like ReveR.store.
Seals & O-Rings: Maintaining the tool's internal compression requires intact O-rings on the pistons (#52, #53, #55) and rotary shaft seals (#84, #85).
Lubrication: Proper operation depends on high-quality grease and gear oil. Specific maintenance sets often include original Hilti machine oil and specialized grease for the bit shank. Troubleshooting Guide Hilti TE 22 has stopped working, check these common failure points:
Won't Turn On: Inspect the power cord (#17) for damage, the switch (#97), and the carbon brushes (#101) for excessive wear.
No Hammering Action: This often indicates a failure in the piston O-rings or the conrod assembly.
Stuck Drill Bit: A build-up of debris in the chuck or a failed locking sleeve can cause bits to jam. Regular cleaning and greasing of the bit shank can prevent this.
