Cat 120E Excavator Undercarriage Parts Selection
Model Compatibility
Getting the right fit for your Cat 120E excavator undercarriage parts is the first step. You want every part to match your machine’s specs. If you skip this, you risk breakdowns and wasted money. Always check your model number and compare it with the part’s details.
Here’s what you should look for when matching parts to your Cat 120E:
Application: Think about how hard your machine works. Is it light, medium, or heavy duty? The right part depends on this.
Arrangement Type: Find out if your undercarriage frame is base, bolt-on, carbody, fixed, or oscillation. This affects which parts will fit.
Bolt-On Sprockets: These make maintenance easier and help keep everything lined up.
Track Shoe Selection: Pick the narrowest track shoe that still gives you enough grip. This helps reduce wear and keeps your machine moving smoothly.
Tip: Always double-check the part number and your machine’s serial number before you buy. Even a small mismatch can cause big problems.
Caterpillar designs Cat 120E excavator undercarriage parts for tough jobs. Here’s a quick look at the main parts you’ll need:
Part | Key Features |
|---|---|
Sprockets | Built for long life and tough conditions |
Rollers | Single and double flange options, handle extreme work |
Idlers | Made from high-strength steel for reliability |
Track Assembly | Greased or sealed chains, available in Standard or Heavy Duty |
Track Pads | Different grouser setups and mud-hole options |
Track Adjusters | Direct replacements, made for extreme working conditions |
Choosing the right parts means fewer breakdowns and better performance. You keep your excavator running strong, no matter the job site.
Size and Weight
Size and weight matter more than you might think. If you pick parts that are too heavy or too light, your excavator may not work as well. Heavier machines use more fuel. This means higher costs for you. Lighter parts might not last as long, especially on rough ground.
Let’s break down why size and weight are so important:
Heavier undercarriage parts increase fuel use. Your engine works harder, and you spend more on fuel.
The condition of your undercarriage affects how well your machine runs. Worn-out parts can slow you down and cost more in repairs.
If parts don’t line up right, you get uneven wear. This leads to more breakdowns and higher bills.
Rocks and debris can damage your undercarriage. This reduces traction and makes your excavator less stable.
Note: Always balance the weight of your undercarriage parts with the type of work you do. Heavy-duty jobs need stronger, sometimes heavier parts. Lighter jobs can use standard parts to save on fuel.
When you choose Cat 120E excavator undercarriage parts, think about both the job and the ground you work on. Mud, rocks, and slopes all change what you need. The right size and weight keep your machine safe and efficient.
You can see the importance of undercarriage parts in every job. The right choices help you avoid costly repairs and keep your excavator working longer.
Job Site and Application Factors
Terrain and Environment
Every job site is different. You might work on rocky ground one day and soft mud the next. The type of terrain changes what you need from your undercarriage. If you work in rocky areas, you want parts that can handle sharp edges and heavy impacts. Muddy or wet ground needs parts that keep mud from building up and slowing you down.
Wet conditions can speed up rust and corrosion on your undercarriage. When moisture gets into the metal, it can weaken the parts and make them wear out faster. Extreme heat or cold also affects how long your excavator undercarriage parts last. Hot weather can make rubber parts crack, while freezing temperatures can make metal brittle.
Here are some tips for matching your undercarriage to the environment:
Use sealed or lubricated track chains in wet or muddy areas. These keep water and dirt out.
Pick track shoes with wider pads for soft ground. This helps spread the weight and keeps you from sinking.
Choose narrow, heavy-duty shoes for rocky or hard ground. These give you better grip and last longer.
Look for extra-strong rollers and idlers if you work on rough terrain often.
A quick table can help you decide:
Terrain Type | |
|---|---|
Muddy/Wet | Sealed chains, wide track shoes, mud holes |
Rocky/Hard | Heavy-duty shoes, reinforced rollers |
Sandy | Standard shoes, sealed pins and bushings |
Frozen | Tough steel, anti-corrosion coatings |
Workload and Application
Think about how hard your excavator works each day. If you use your machine for light digging or landscaping, standard undercarriage parts might be enough. But if you move heavy loads or work long hours, you need stronger parts.
Ask yourself these questions:
Do you run your excavator all day, every day?
Do you lift heavy rocks or dig deep holes?
Does your job site have steep slopes or lots of debris?
If you answer yes to any of these, you should look for heavy-duty or specialized excavator undercarriage parts. These parts cost more at first, but they last longer and save you money on repairs.
Tip: Heavy-duty undercarriage parts are a smart choice for tough jobs. They handle more stress and keep your machine running when the work gets rough.
You can also mix and match. For example, use heavy-duty rollers with standard track shoes if you only need extra strength in one area. Always check your machine’s manual to see what combinations work best.
Choosing the right undercarriage for your job site and workload keeps your excavator safe and efficient. You avoid breakdowns and get more work done with less trouble.
Excavator Undercarriage Parts Quality
Material and Durability
When you check excavator undercarriage parts, look at what they are made of. You also want to know how long they will last. Not every undercarriage part is made the same way. Some use cheaper materials, but others use strong steel and special treatments. What you pick depends on how hard you use your machine. It also depends on how long you want to keep it.
Here’s a simple table to help you compare:
Quality Level | Material Grade | Typical Use Case | Durability / Lifespan |
|---|---|---|---|
Economy | Lower-grade materials | Light-duty, occasional use | Shorter lifespan, less durable |
Standard | Higher-grade materials | Medium-duty, regular use | Longer lifespan than economy parts |
Heavy-duty | Highest-grade materials | Heavy-duty, constant use | Longest lifespan, most durable |
Parts made with alloy steel last the longest. Forging and heat treatment make them even stronger. These steps help your undercarriage fight wear and last longer. This is true even in tough places. If you use your excavator every day or in rough spots, heavy-duty parts are best.
Maintenance Needs
Taking care of your excavator is important. Some undercarriage parts need more care than others. You should think about cost, downtime, and how long parts last. Think about how long you want to keep your machine. If you plan to keep it for years, buying good parts can save you money.
When you pick between OEM and aftermarket parts, remember these things:
OEM parts follow strict rules, but they can cost more and take longer to get.
Aftermarket parts are often cheaper and arrive faster, but quality can change by brand.
Some aftermarket parts have strong warranties, like 3 years or 4,000 hours.
OEM parts might mean more waiting if you need to order them, but aftermarket parts may be ready right away.
Tracks and track shoes get used a lot, so check them often. Clean your undercarriage after each job. This helps you find problems early and keeps your machine working longer. If you want less work, pick sealed or lubricated parts. These keep dirt and water out, so you do not have to fix them as much.
Tip: Always think about how long you will use your excavator before you buy parts. Spending more at first can mean fewer problems later.
