This guide will teach you how to change excavator buckets and remove and change excavator bucket teeth to make the most of your earthmoving machinery. 

Excavators and mini excavators are versatile equipment, suiting projects across multiple industries, from construction and mining to maintenance and materials handling. The bucket and teeth styles you choose will play pivotal roles in project efficiency and vary depending on the nature of the job. The correct bucket and bucket tooth type can reduce downtime, enhance productivity, increase cost efficiency and expedite a project.

How to Change Excavator Buckets

Like any well-used components, excavator buckets wear out over time. If you do not replace a worn bucket, you risk exposing and damaging your excavator&#;s shank. To prolong your excavator&#;s life, you must practice preventive maintenance, including changing worn-out buckets with new ones.

The bucket style you choose will also impact job efficiency. You might need to change buckets quickly on the job, as specific bucket styles are better suited to particular tasks. Knowing how to change your excavator bucket quickly will help keep your machinery in excellent condition and boost productivity.

Follow these steps to change your excavator bucket:

1. Level your buckets: Place your old and new buckets side-by-side on a level surface. 
2. Remove the bucket&#;s lynchpins: Use a screwdriver to remove the lynchpins from your current excavator bucket.
3. Detach the bucket: Lift the boom arm up and away from the excavator bucket until it is no longer attached.
4. Align the new bucket: Reduce your excavator&#;s throttle speed to its lowest setting. Maneuver your boom arm to align the excavator&#;s dipper links above the new bucket&#;s ears.
5. Lower the boom arm: Lower the boom arm and maneuver the dipper to line up with the new bucket&#;s lynchpin holes.
6. Slide the pins into place: Slide the rear lynchpin into place. Be careful to avoid placing your fingers in the lynchpin holes.
7. Lift the new bucket: Carefully lift the bucket into the air once you have the rear lynchpin inserted. The rear lynchpin should snap into place.
8. Retract the ram: Retract the excavator&#;s ram to insert the front lynchpin.
9. Move the bucket: Move the dipper around, rotating the bucket to ensure the bucket is secure and has a full range of motion. 

How to Remove Excavator Bucket Teeth

Like buckets, bucket teeth also wear down over time. Periodically replacing bucket teeth is crucial to avoid damaging their adapters. Learn how to replace teeth on an excavator bucket in a few easy steps below.

1. Select a Suitable Bucket Tooth Type

The first step is identifying excavator bucket teeth that are appropriate. Each bucket tooth type has a purpose suited to particular excavation jobs. The different teeth varieties include the following:

• Chisel tooth: A chisel tooth is an earthmoving tooth with a high stacking surface. These teeth allow you to expertly excavate large quantities of soil, sand and gravel.
• Tiger tooth: Tiger teeth come in single or &#;twin&#; teeth. Both a single and twin tiger tooth can easily penetrate frost, rock and hard soil during digging and trenching projects. However, a twin tiger tooth has a longer shelf life due to its additional penetration surface.
• Rock tooth: A rock tooth is a steel chisel tooth that penetrates and moves rock, iron ore, stone or hard ground.  

2. Identify the Correct Pin Installation Style

Next, identify your excavator&#;s bucket tooth-pin installation style and gather your tools or removal device kit. There are two primary pin installation styles for excavators:

• Top pin: A top pin installation style refers to an excavator bucket with a vertical or top-to-bottom tooth pin. 
• Side pin: A side pin installation style features a horizontal or left-to-right pin and requires a longer tool to disassemble. 

3. Locate Your Factory Bucket Tooth Size

Choosing the correct bucket tooth size is crucial. You can identify the style and size of your factory bucket teeth by locating the part number on the tooth&#;s surface, interior wall or pocket edge. You can also measure the pin, retainer or tooth pocket size to identify tooth size.

4. Replace the Teeth on Your Excavator Bucket

Once you have the correct tooth size and your assembly toolkit ready to go, follow these steps to replace your excavator&#;s teeth:

1. Stabilize the excavator bucket on a flat surface.
2. Knock out the existing roll or keener pins with a pin removal device.
3. Use a brush to remove debris or stains from the excavator&#;s shank adapter.
4. Place the new tooth over the bucket&#;s adapter.
5. Hammer the new roll pin into the adapter&#;s pinhole opening until it is secure.

How to Change Buckets on a Mini Excavator

Mini excavators are compatible with several bucket styles, making them suitable for various projects across multiple industries, including construction, farming, landscaping and maintenance. If you are familiar with changing excavator buckets, you will be pleased to know changing the bucket on a mini excavator is a similar process, regardless of the bucket type:

1. Remove bucket safety pins: First, set your bucket next to the new bucket on a level surface. Lift the retainer ring and slide it out to remove the safety pin from your bucket.
2. Detach the bucket from the excavator: Once you have removed the safety pin, lift the boom arm away from the bucket to loosen the lynchpin. Remove the lynchpin to detach the bucket from the excavator.
3. Align the dipper with the bucket: Reduce your excavator&#;s throttle speed and align the dipper links above the new bucket&#;s ears.
4. Pick up your new bucket: Slowly pick up the new bucket and maneuver it so that the pinholes align.
5. Replace the lynchpin: Slide the new lynchpin into place after aligning the bucket&#;s pinholes. Once the lynchpin is in place, secure it with the safety pin.

As time goes by, machines and equipment have evolved into something more useful to humans. The excavator and excavator buckets are definitely among the most needed equipment in the construction arena these days. With these tools, people will never have to use their bare hands just to excavate a certain area. There are different types of excavator buckets that are being used today. Among them are:

Digging Bucket &#; Majority of excavator buckets are mainly used for digging in a channel which reflects the features of its design. Whether it is for excavating rock, frost, or loam, buckets usually follow the form-to-function rule. Digging buckets for mushy as well as soft soils do not have long teeth, and they are often blunt. As for frost or rock, the bucket&#;s teeth are typically long and pointed to have a better application of leverage and force for prying. The width of the bucket also varies. In hard soil or ground, a bucket which is narrow applies a more concentrated force to penetrate the ground. It also has a short cutting edge.

Another feature of this excavator bucket is the space between the tooth tips as well as the stick bucket pin boss. This distance is known as the tip radius, and is normally shorter in digging buckets which are used for the excavation of hard ground. Because of the short distance it has, it may provide a better mechanical leverage for filling and curling the bucket. A digging bucket which is well-designed will use these features to make for an efficient as well as durable device.

Rock Bucket &#; This type of bucket is a variant of the aforementioned digging bucket, except it has a few modifications in its design for a unique application. When it comes to extreme ripping as well as prying rock, this requires a structure which is robust and heavily built. The excavator bucket must have long and sharp teeth mounted on a V-shaped or straight cutting edge. The excavator bucket must have enough strength to focus power for prying as well as ripping rock loose, at the same time, preserving its structural integrity. Typically, these buckets are narrower and have shorter tip radii as compared to common digging buckets which are used in softer media or materials.

There are so many factors that you need to consider when selecting the correct excavator bucket and these are:

The excavator bucket&#;s proposed purpose &#; know if it is for backfilling, clearing, digging or clearing

The density as well as composition of the soil &#; know if it is loam, clay, or rock?

The make of the machine &#; know how much it weighs and how much power does it have.

The width of the bucket &#; know the guarding, the radius, and the tip
