Popular Atlas Copco Hydraulic Breaker Models

Atlas Copco's hydraulic breaker range includes numerous models. Common models include:

Important: Atlas Copco parts can vary by production generation and serial number. Always verify the breaker identification plate before ordering replacement components.

What Are the Most Common Atlas Copco Hydraulic Breaker Replacement Parts?

For routine hydraulic breaker maintenance and rebuilding, frequently requested parts include:

• Hydraulic breaker piston

• Upper and lower bushings

• Diaphragm

• Accumulator components

• Seal kit

• Tool retainer

• Lock pin

• Control valve

• Charge valve

• Back head

• Front/lower hammer components

• Through bolts and fasteners

• Chisel / moil point

• Blunt tool

• O-rings and hydraulic seals

Wear depends heavily on application, lubrication, hydraulic settings and operating conditions.

Replacing worn components before secondary damage develops can help reduce repair costs and machine downtime.

How Do I Find the Correct Atlas Copco Hydraulic Hammer Part?

For accurate matching, do not order a replacement part based only on its appearance.

Provide:

Breaker Model + Serial Number + Original Part Number + Part Name + Clear Photos

For example:

SB 302 + Serial Number + 3315 3021 00 + Piston

This gives the supplier significantly more information than simply asking for an “Atlas Copco breaker piston.”

The manufacturer's own parts system also uses model and serial-number information to identify the appropriate spare-parts book, which is why serial-number confirmation is important when cross-referencing aftermarket components.
