How often do you grease a hydraulic hammer?

When it comes to keeping your demolition gear in top shape and running smoothly, greasing your hydraulic breaker is your best defense! It might seem tedious, but this preventative step can save you a lot of time and money in the long haul. Let’s dive into why it’s crucial and how to grease your hydraulic hammer properly. Read on for more details!

Why Is Grease Necessary?

If you do one thing for hydraulic hammer maintenance, it should be greasing. Besides the chisel hitting the rock, the most significant wear area in construction and demolition is where the tool meets the bushings. Hydraulic hammer lubricant or chisel paste lubricates the tool bushings, retainers, and demolition tool, dispersing heat and keeping debris out of the breaker. Skipping lubrication at the correct intervals dramatically increases wear, leading to frequent and costly tool bushing and tool replacement. If you do nothing else for your hydraulic hammer, grease it regularly with the right hammer grease.

What is the right grease for my hydraulic hammer?

Chassis grease won’t properly lubricate a hydraulic hammer! It’s meant for slow speeds, low angles between smooth surfaces, without any impact. A hydraulic hammer tool moves in its bushings at 300 to 1,200 cycles per minute at sharp angles while dealing with foreign matter, high heat, and severe impact. If you’re not using Gorilla Goo™ chisel paste or a proper hammer grease designed for hydraulic hammers, you’re wasting your time. Chassis grease isn’t built for such harsh conditions.

How and how often should I grease my Hydraulic Hammer?

Every hydraulic breaker needs to be lubricated in a vertical position with the weight of the carrier pressing down on the tool. If you don’t do it this way, the chisel paste will get between the top of the demolition tool and the strike piston, causing damage.

Always lubricate thoroughly when installing a new demolition tool! Often, you’ll need an entire tube of chisel paste or hammer grease to coat the wear surfaces inside the hammer, including the tool retainer slots.

CAUTION: Keep the top cap that contacts the strike piston clear of grease to avoid compacting grease against the strike piston and causing internal damage.

Every hydraulic hammer needs greasing every two working hours. For hammers with a tool up to 3 inches in diameter, 10 to 15 pumps from a grease gun will do. For hydraulic breakers with tool diameters over 4 inches, 20 pumps are required. If you want to save time and ensure your hydraulic breaker always gets adequate lubrication, consider installing a carrier or hammer-mounted automatic greaser.

However, the best way to ensure proper lubrication is a trained operator! They should always check where the demolition tool meets the lower bushing to ensure there’s a steady coating of grease. Visual monitoring is the last line of defense against running a demolition chisel and its bushings dry.
