Original JCB Extreme Performance Hammer Grease (400g) suitable for JCB - 4003/2107
Technical Specification and Compatibility
Specialized 4003/2107 hydraulic hammer grease from the Extreme Performance Hammer Grease series, manufactured by JCB. This is an advanced lubricant based on a unique aluminum complex formula. Dedicated to lubricating chisels and bushings in breakers operating under the harshest conditions. Offered in standard 400g cartridges, fitting typical grease guns.
By choosing genuine JCB workshop fluids, you ensure optimal working conditions for your machines. Original greases are tested against specific loads found in JCB attachments, guaranteeing maximum protection against wear.
Properties of JCB Extreme Performance Grease
Temperature Resistance:The aluminum-based formula remains stable even at extremely high temperatures generated by chisel friction in the bushing.
Water Resistance:The grease features exceptional resistance to water washout, making it ideal for underwater work or in rain.
EP (Extreme Pressure) Protection:Additives protect metal surfaces from seizure under extremely high unit pressures.
Adhesion:Excellent adhesion to metal prevents grease from leaking out of the tool, ensuring continuous lubrication.
Application in machinery
Attachment Type
Recommended Use
JCB Hydraulic Hammers
All series (HM, Hammermaster) - chisel and bushing lubrication.
Other Brand Hammers
Universal application in demolition breakers requiring high-temperature resistant grease.
This grease is dedicated to impact applications. For rolling bearings, other types of grease (e.g., lithium) are recommended.
Related Parts and Hardware
To apply the grease, a hand, foot, or pneumatic grease gun adapted for 400g cartridges is required. It is also worth checking if the grease nipples on the hammer are not clogged.
⚠️ Operational Warning
Using standard grease (e.g., for bearings) in a hydraulic hammer leads to it "melting" under temperature, resulting in chisel seizure and damage to guide bushings. Always use dedicated hammer paste.
Part Role in the Machine and Failure Diagnostics
Grease 4003/2107 creates a protective film between the chisel and bushing, reducing metal-to-metal friction during impact.
›Dry chisel (risk of tool breakage).
›Excessive play (bushing wear caused by lack of lubrication).
› Overheating of the lower hammer part.
› Chisel seizure in the bushing.

🔧 Expert Guide: Key Installation Tips
Frequency: Hydraulic hammers require lubrication much more often than excavator pins – typically every 2-3 hours of continuous operation.
Technique: Grease the hammer in a vertical position, pressing the chisel against the ground (so it retracts fully). This prevents grease from entering the impact chamber, which could damage piston seals.
Amount: Pump grease until fresh grease starts to flow out around the chisel.
Frequently Asked Questions (FAQ)
Can I use this grease for bearings?
This grease is optimized for high pressures and temperatures (impact), not for high-speed rotation. For wheel bearings, dedicated lithium greases are better, although in emergencies, for slow-moving pins, this grease will also work.
What is the benefit of aluminum base?
The aluminum complex thickener provides excellent water resistance and a high dropping point. The grease does not flow out of a hot tool as easily as lithium greases.
Which grease guns does it fit?
The 400g cartridge is a standard size (rigid tube), fitting most manual, pneumatic, and electric grease guns available on the market.
