How To Change Bobcat Breaker Bit? Best 268 Answer

It’s important to keep your excavator up and running as deadlines near – but there are some bad habits and behaviors that all too many owners and operators fall into that will affect their excavator’s performance and lifespan. In this Shop Talk blog post, we talk about four bad habits compact excavator owners and operators need to break.

1. Forgot the gear oil in the final drive

It’s a shame that the final drive can so easily be forgotten during maintenance, because it keeps your mini excavator moving. You should check the gear oil level in the final drive about every 100 hours. If you run out of gear oil and you keep the drive running, you will ruin the drive. Also, remember that gear oil, like any lubricant, degrades over time and with exposure to heat. You should therefore also change the transmission oil at least once a year. Otherwise, you’ll end up with a gritty mess in your planetary hub, like the failed final drive shown below. Don’t let that happen to your final drive!

2. Pins and bushings not properly lubricated

The pins and bushings of your compact excavator need to be lubricated every day of use. A good rule of thumb is to use 1-3 squirts of grease. Too little grease leads to accelerated wear because it is not sufficiently lubricated. Some people mistakenly think that if a little fat is good, a lot of fat is even better. However, using too much grease doesn’t help with lubrication – it creates a mess, attracts and traps abrasive materials (dust, sand, gravel) that can do as much damage as no grease at all, and can also heat there capture where it wants to cause an increase in wear-causing friction.

3. Never change the hydraulic fluid

Depending on the make and manufacturer of your equipment, the hydraulic fluid needs to be changed between 2,000 and 4,000 hours – be sure to follow the manufacturer’s recommendations for this. Like transmission oil, it degrades over time and at elevated operating temperatures. You should also flush the hydraulic system and refill with fresh fluid if a catastrophic failure has occurred anywhere in the hydraulic system, such as: B. with a failed pump or a failed traction motor.

4. Rare cleaning of the undercarriage

Landing gear accounts for a significant portion of your M&O costs. A simple way to help ensure the longevity of your undercarriage is to clean it. If not cleaned regularly, dirt can become tightly packed – so tight, in fact, that it can push aside seals and introduce abrasive contaminants where they can do the most damage. A good example of this can be seen in the image below where the main seal has been pushed apart by tightly packed dirt and sand.

If the undercarriage is dirty, you may not be able to identify potential problems such as uneven track wear or leaking fluids during daily inspections or walk-arounds. The more dirt that accumulates – especially when it’s heavy mud mixed with rocks or gravel – the heavier your gear becomes, which in turn increases fuel consumption.

Conclusion

If you want your mini excavator to have a long life with minimal downtime and maximum efficiency, breaking these four bad habits is a good place to start. Replace them with these positive habits: checking and changing the gear oil in the final drive, properly lubricating the pins and bushings on your excavator, changing the hydraulic fluid according to the manufacturer’s recommendations, and cleaning the undercarriage regularly. This final drive maintenance will make a big difference in the performance and life of your final drive.

hammer fat

To prevent premature tool and tool bushing wear, the tool must be adequately supplied with the correct grease. The tool must be pressed against a hard surface until it stops in the hammer. This will ensure proper grease distribution between the tool and the tool bushings.

The type of fat used is very important. NPK recommends a lithium base grease, molybdenum (molybdenum disulfide) or other surface protecting additive, EP (Extreme Pressure), NLGI #2 grease. A high dropping point grease (500°F, 260°C) is desirable.

Hydraulic breakers/hammers are essential pieces of equipment in the construction machinery industry. They are used in both building and demolition work for the construction industry. For construction, they can be used to dig holes, break up rocks, or break up the dirt to make digging a hole easier.

During demolition, the hammer/breaker can quickly break up concrete, walls, and foundations to collapse various structures. Because hammers/breakers can easily break through hard material, these types of tools are great for the mining industry.

Hammers/Hammers are commonly mounted on skid steers, mini excavators, backhoes and large excavators. These tools are great for building and tearing down. However, the most interesting thing about these hammers/breakers is how they work.

The science behind a hydraulic breaker | interrupter

Hydraulic breakers/breakers work with hydraulics, which is the reason for their name, but it’s also what sets them apart. Pascal’s law, a mechanical principle of mechanics, is the basic function of the hydraulic hammer. By applying pressure to one portion of a liquid, the pressure is transmitted to all areas of the liquid, multiplying the force.

hydraulic breakers | Breakers use hydraulic oil that cannot be compressed, with the pressure being stored in a small canister. This hydraulic system provides the power. Normal hand hammers cannot even be compared to the impact of a hydraulic hammer | interrupter.

There are two main types of hydraulic breakers | Breakers, with different valves. One type has an inner valve while the second type has an outer valve. The internal parts are mostly the same, with the necessary cylinder to provide the pressure and a piston to convert the energy into the impact action. Other similar hydraulic parts include:

Side Bars: Designed to support mounted hammer applications

Nitrogen Chamber: A low-pressure chamber for energy supply

Main Valve: The only moving part other than the piston that helps with hammering

Front Cap: Holds the hammer attachment in place during impact

Hydraulic Breaker Classes

hydraulic breakers | Demolition hammers come in different sizes/classes to suit a variety of jobs. Each has a recommended usage amount so users know which class is best for each job. While each hammer/breaker has a different gauge depending on the brand, here are some basic stats on each class so you can see their potential impact on a job:

Small class: The impact frequency with this size is between 400 and 1200 BPM at 1400 to 2175 PSI

Middle class: The stroke frequency here is 370-700 BPM at 2175 to 2610 PSI

Great Class: This size has a pounding frequency of 200 to 400 BPM at 2300 to 2610 PSI

These measurements show how many times the hammer can hit the target in one minute, along with the pressure used. It is important that the correct class hammer is used for each job. Using a hammer/breaker with too much pressure for a job that requires less can cause too much damage.

If you are in the market for a hydraulic breaker/hammer and have questions about what size is right for your project, we are always here to answer those questions via [email protected].

A hammer is mounted on the left side of the excavator

A breaker is a powerful percussion hammer attached to an excavator to demolish hard structures (rock or concrete). It is driven by the excavator’s auxiliary hydraulic system, which is equipped with a foot valve for this purpose. In addition, demolition crews use the pickaxe for jobs that are too big for jackhammers or for areas where blasting is not possible for safety or environmental reasons.

Breakers are often referred to as “hammers”, “peckers”, “hoe rams” or “hook rammers”. These terms are popular and commonly used by construction/demolition workers.[1][2] The first hydraulic hammer, hydraulic hammer HM 400, was invented in 1967 by the German company Krupp (today German company Atlas Copco) in Essen.[3]

Environmental Protection Agency (EPA) emissions regulations mandate the use of superior quality engine oil to maintain proper engine performance. An advantage of the newer oils is that they are compatible for use in older engines.

There are two characteristics to consider when choosing the right motor oil for your compact equipment: classification and viscosity grade.

Oil Classifications

Oil categories for diesel engines start with “C”. The American Petroleum Institute (API) CJ-4 category was introduced in 2006 and was intended for high-speed four-stroke diesel engines. It was developed to meet 2007 model year highway exhaust emission standards and is uniquely formulated not to compromise the durability of the new diesel engine technology.

In December 2016, API introduced a new category of heavy-duty oil engine: CK-4. The new formulations help protect engines from high heat and high stress conditions typical of non-highway applications. CK-4 oils are backward compatible with all trucks and non-road equipment that use CJ-4 oils.

Always use a premium oil that meets or exceeds API service classification CK-4 for EPA compliant engines.

viscosity adjustment

It is important to correctly match the viscosity grade of your engine oil to the outside temperatures in your working environment. Always refer to the Operation and Maintenance Manual to determine the weight of oil that is recommended under various conditions.

A 10W-30 oil is a common factory fill for many current production machines. It offers peak performance in temperatures typically ranging from zero degrees Fahrenheit to 90 degrees Fahrenheit and above. A 15W-40 weight works well from 25 degrees F to 110 degrees F and above.

Synthetic or synthetic blend oils are formulated with additives that can extend drain intervals and promote longer engine life. A 5W-40 weight synthetic oil is typically capable of providing protection in harsh conditions as low as minus 40 degrees Fahrenheit and as high as 120 degrees Fahrenheit.

Hydraulic and hydrostatic oils

Hydraulic and hydrostatic oils are tailored to the growing demands on hydraulic components and are available in different types for different applications:

High Performance – Typically a custom blend of high quality lubricants designed to provide peak flow in sub-zero temperatures while maintaining stability during periods of high temperature use.

— Typically a custom blend of high quality lubricants designed to provide peak flow in sub-zero temperatures while maintaining stability during periods of high temperature use. Synthetic – An advanced fluid technology designed to optimize cycle times and productivity and provide good cold weather fluidity for seasonal changes.

— An advanced fluid technology designed to optimize cycle times and productivity and provide good cold weather fluidity for seasonal changes. Biodegradable – Introduced to meet customer demand as federal, state and local governments set environmental project restrictions. It is biodegradable, non-toxic and formulated to reduce the potential for environmental damage.

Fat

Many machines require grease to lubricate pivot points where pins and bushings are located. The lubrication points must be lubricated at various intervals specified by the machine manufacturer. When used correctly, the right type of grease will help extend component life:

Multipurpose #2 – Designed for normal applications, it provides lubrication to prevent rust and corrosion and protects against heavy and shock loads.

— Designed for normal applications, it provides lubrication to prevent rust and corrosion and protects against heavy and impact loads. Heavy Duty – Contains molybdenum for better adhesion to all surfaces, provides water resistance, high pressure capability, cold temperature pumpability and good gasket compatibility.

— Contains molybdenum for better adhesion to all surfaces, water resistance, high pressure capability, cold temperature pumpability and good seal compatibility. High Performance — Formulated to provide high temperature performance under severe operating conditions, it is intended for lubrication points involving both sliding and rotary motion.

If your excavator tracks are too tight or too loose, you risk excessive undercarriage wear. The undercarriage carries the entire weight of the excavator. A few small adjustments can go a long way in improving device performance and your bottom line.

Ensure your undercarriage can get the job done and minimize your operating costs by making excavator chain inspections part of your regular maintenance program.

How do you tighten the crawler tracks of an excavator?

If you have the tools and a safe environment to do the job yourself, you can learn how to adjust chains on any size excavator. Always work on firm, level ground and follow all safety procedures required when performing maintenance or repairs.

In most cases, adjustments are made in four steps:

Raise the chain: turn the cab perpendicular to the undercarriage and lower the boom. Dig in the shovel and use the boom to push the side of your excavator up in the air – high enough for you to work on comfortably. Clean Track: Before beginning track adjustment of the backhoe, remove dirt and debris. This process removes anything that might affect your chain tension and makes it easier to see what you’re doing. Take Your Measurements: Measure how much your excavator chains are sagging to see what you need to do. Use a tape measure and get an accurate measurement from the lowest point of your track to the top of the running shoe. Make any necessary adjustments: You can find out how tight your excavator chains should be from your operating instructions. If yours are out of spec, you’ll need to adjust your grease levels until the chain tension meets your recommended parameters.

How do you lubricate excavator chains?

To lubricate excavator chains, remove the cover plate that shields your grease fitting and adjustment valve. If you want to increase the tension, use your grease gun and add grease. To loosen excavator chains, bleed the adjustment valve until you are happy with the results.

The Haubenschild Dairy Farm in Minnesota milks 1,500 cows three times a day. Most of the forage is grown right on the farm. Bryan Haubenschild, farm owner and operator, explains that “dairy farming is a very labor intensive job”. He says, “There’s always three people milking cows, there’s always one person feeding cows, manure alleys need clearing.” Skid steers are important tools on the farm, and it’s vital to have them on hand at all times , especially since the farm supplies up to 150 cows a day and transports milk twice a day. Skid steer loader maintenance is a must and this is where automatic lubrication shows its value. Bryan explains why in the following video:

HOW OFTEN DO YOU LUBRICATE A COMPACT BEARING? Skid steer pins, bushings, and other pivot points throughout the machine should be lubricated every 10 hours of operation, if not more often, depending on working conditions. Bryan explains that on his farm, “the skid steers are used 10 to 12 hours a day, 365 days a year, so the grease points should be greased…daily.”

HOW TO LUBRICATE A SKID STEER? Servicing the skid steer, including manual greasing, is a cumbersome and time-consuming process. Always refer to the owner’s manual for proper lubrication practices. Machine lubrication points must be thoroughly cleaned to ensure no contaminants get into the lubricant. Automatic lubrication systems save you valuable time by applying precise amounts of grease to each lubrication point at the specified time while your equipment is in operation. Bryan explains, “The working environment of our skid steer loader is an extremely dirty environment. [But there is] no risk of contaminants [getting into the grease] because [the automatic greasing system] is a closed system.” He adds that if a pin fails on the skid steer loader, the machine will be idle for half a day. But, he says, “Graco’s G-Mini automatic greaser keeps the machine running.”
