Bosch 2610005307 Upper Piston Bumper

Product Description

The BOSCH 2610005307 is an OEM-authorized upper piston bumper designed to absorb impact at the top of the piston stroke in compatible Bosch rotary hammer and demolition hammer tools. This small but critical component prevents metal-to-metal contact during the hammering cycle, protecting internal mechanism components and extending tool service life. At 0.98 inches in each dimension, it is a compact part that requires precise fitment. Installation is typically performed by power tool repair technicians during preventive maintenance or after wear inspection.

This upper piston bumper is suited for use in Bosch rotary hammers and similar pneumatic-mechanism power tools where the piston assembly requires a buffer at top dead center. It is commonly replaced during service intervals when the bumper shows signs of compression set, cracking, or deformation. Proper replacement restores correct piston stroke dynamics and reduces vibration transmitted through the tool body during operation.

Installation Notes

Installation should be performed by a qualified power tool repair technician. Disconnect the tool from all power sources and remove the battery or unplug the cord before disassembly. Full disassembly of the piston mechanism is typically required to access and replace this component, so familiarity with the tool service manual is recommended. Inspect surrounding piston and cylinder components for wear before reassembly.
