Joint Sleeve & Piston Assembly (8-23) For Tcrh0800

Features

• Joint sleeve and piston assembly kit Replaces core hammer mechanism components in one service-ready kit.
• Parts-diagram referenced fitment Covers reference parts (8–23) for accurate servicing on the TCRH0800.
• Designed for TCRH0800 Intended for use where this internal hammer assembly is specified for the model.

Benefits

• Restores hammering power: Helps bring back effective impact action for concrete and masonry drilling.
• Improves smoothness and consistency: A renewed mechanism can reduce uneven blows, rattles and rough running.
• Supports longer tool life: Replacing worn internal parts helps prevent further damage to gears, bearings and the front assembly.

Extra Information

• This service kit covers the joint sleeve and piston assembly components referenced as parts (8–23) for the TCRH0800.
• Recommended if hammer action is weak, inconsistent, noisy, or if internal parts show scoring, wear or heat damage during strip-down.
• Use correct grease for rotary hammers and avoid overfilling—too much grease can cause overheating and poor performance.

Specifications

Safety

• Disconnect the tool from the power supply before any servicing, stripping, or reassembly work.
• Wear eye, ear and dust protection when testing rotary hammers and when drilling masonry.
• Handle internal parts carefully—springs and small components can release suddenly during disassembly.
• After reassembly, do a cautious no-load test first, then a light-duty test in suitable material before returning to full operation.
