A Complete Guide to Loader Bushing Part Numbers and Sizing

Looking to change a Loader Bushing without using your tractor? You have many choices. You can pick aftermarket, universal, or custom bushings. Many people like plastic bushings because they are light and do not rust. Some people choose composite or alloy bushings for more strength and longer use. Some bushings use self-lubricating materials, so they are easier to care for. No matter what you choose, getting the right part number and size is important. If you want your loader, excavator bushing, or bucket pin to work well, paying attention to these things saves you time and money.


Key Takeaways

  • Pick the loader bushing material that fits your job. Steel is strong. Bronze lasts a long time. Plastic is light. Self-lubricating types are easy to care for.

  • Measure your loader bushing with a caliper or micrometer. Get the inner diameter, outer diameter, and length. This helps you get the right size.

  • Use part numbers and guides to find the right loader bushing. If standard parts do not fit, look at custom options.

  • Buy from trusted suppliers. They should have good quality control. They should answer fast and help with custom orders. This keeps your loader working well.

  • Check your bushings and pins often for wear or damage. This helps you avoid big repairs. It also makes your equipment last longer.


Loader Bushing Alternatives

When you need a new loader bushing, you have many choices. You do not have to use your tractor or only OEM parts. Let’s look at your main options. This helps you pick what is best for your loader, excavator bushing, or bucket pin.


Materials

Loader bushings can be made from different materials. Each type has its own good points:

  • Steel: DOM steel tubing is great for homemade bushings. It works well with 1018 steel pins. You can drill and tap these for grease fittings. This helps them move smoothly.

  • Bronze: Bronze bushings, like sintered bronze and graphite-impregnated bronze, last a long time. They give a smooth surface and handle heavy loads. They also do not wear out fast.

  • Plastic: Some people use plastics like Delrin. These are light and do not rust. But they can wear out faster if you use them a lot.

  • Composite and Self-Lubricating: Self-lubricating bushings use special materials like PTFE liners or solid lubricants. These bushings last much longer than regular ones. You do not need to grease them. They work well in dusty or wet places.

Tip: Self-lubricating bushings save time and money on care. They are quieter and have less friction. This helps your loader work better.


Designs

Loader bushings come in different shapes and styles:

  • Standard Cylindrical: These are the most common and easy to change.

  • Flanged: These have a lip to keep them in place. They help with side loads.

  • Split or Slotted: These are easy to put in and take out. You do not need to take apart the whole machine.

  • Lined or Coated: Some bushings have a graphite spray or manganese phosphating. This makes them slippery and stops rust.

Shanghai Fenghua (SINOTECH Machinery Co., Ltd.) uses special steps like carburizing heat treatment, manganese phosphating, and graphite spray coating. These make bushings harder and stronger. They also stop rust. You can even pick the color for a custom look.


Universal Options

Universal loader bushings fit many machines. They are easy to find and usually cost less than custom ones. Here is a quick chart:

Universal bushings are good for a quick fix or if you have many machines. You can get them from SINOTECH Machinery Co., Ltd., McMaster-Carr, or Grainger.


Custom Solutions

Sometimes, you need something special for your loader. Maybe your loader has special needs or you want it to last a long time. Custom loader bushings are the answer.

Shanghai Fenghua (SINOTECH Machinery Co., Ltd.) can make bushings just for you. You can send them a drawing or a sample. They make many sizes, from small (30mm inner diameter) to very big (300mm inner diameter). You can pick the material, surface finish, and color. Their team uses over 80 high-precision machines and checks quality. You get a bushing that fits well and lasts a long time.

Note: Custom bushings may cost more at first. But they can save you money because they last longer and stop downtime.

If you like to build things, you can make your own bushings. Use DOM steel tubing and 1018 steel pins. Drill holes for grease fittings to keep them smooth. Do not use black steel pipe because it wears out fast.

No matter what you pick, match the bushing to your loader’s needs. Think about where you use it, how much weight it holds, and how much care you want to do. The right loader bushing helps your machine run better and last longer.


Part Numbers

Identification

Finding the right loader bushing part number can feel tricky, but you can do it step by step. Start by looking at your equipment type. Is it a loader, backhoe, or maybe an excavator? Next, check the make of your machine, like Case or another brand. Pick your specific model from the list. You will see a part number, such as D31142, that matches your loader. Always check if the part number fits your model and matches the OEM details.


Here’s a simple way to identify your loader bushing part number:

  1. Choose your equipment type (Loader, Backhoe, Excavator).

  2. Find the equipment make (for example, Case).

  3. Select your loader model.

  4. Look up the loader bushing part number listed for your model.

  5. Double-check compatibility with OEM part numbers.

If you follow these steps, you will find the right part number for your loader bushing.


Cross-Reference

You might want to find an alternative to your OEM loader bushing. Cross-referencing helps you match part numbers with aftermarket or universal options. Many suppliers list bushings by part type, equipment, and compatible brands. This makes it easy to find what fits your loader, excavator bushing, or bucket pin.

Sizing


Getting the right size for your loader bushing is key if you want your machine to run smoothly. If you pick the wrong size, you might see extra wear or even damage. Let’s break down how you can measure, match, and double-check your loader bushing size—even if you don’t have the original part number.


Measuring

You can measure a loader bushing at home with a few simple tools. Grab a micrometer or a caliper. These tools help you get accurate numbers. Here’s what you need to measure:

  • Inner Diameter (ID): This is the hole in the middle of the bushing. It should fit snugly around the pin.

  • Outer Diameter (OD): This is the outside edge of the bushing. It needs to fit tightly in the loader arm or housing.

  • Length (Height): This is how tall the bushing is from one end to the other.


To get the best fit, measure each spot in a few places. Sometimes, bushings wear unevenly. Always use the smallest measurement you find. If you want a little more grip, you can subtract a tiny bit (like 0.002 inches) from your measurement. This helps the bushing stay tight.

Tip: If you use a loader bushing for heavy work, check the fit by pressing the pin into the bushing. It should slide in with a little resistance, but not be too loose.

Here’s a quick table to help you remember the steps:

Step

Matching Specs

Once you have your measurements, you need to match them to your loader’s specs. Loader bushings come in many sizes. SINOTECH Machinery Co., Ltd. supports a wide range:

  • Minimum size: Inner diameter 30mm, outer diameter 40mm, height 10mm

  • Maximum size: Inner diameter 300mm, outer diameter 350mm, height 300mm

If your loader bushing falls within these sizes, you can order a standard or custom part. Always check your loader’s manual or spec sheet. If you don’t have one, measure the pin and housing directly.

Sometimes, you may want to upgrade or replace other parts, like an excavator bushing or bucket pin, at the same time. Matching all your specs together can save you time and money.

Note: SINOTECH Machinery Co., Ltd. can make custom bushings if your size is not standard. Just send them your measurements or a sample.


Sizing Charts

Sizing charts make it easy to find the right loader bushing. You just match your measurements to the chart. Here’s a simple example:

If you use inches, you can convert millimeters by dividing by 25.4. For example, 50mm is about 1.97 inches.

Conversion Tip:
To convert millimeters to inches, use this formula:
inches = millimeters ÷ 25.4

If you want a perfect fit, always double-check your numbers. If you are not sure, ask for help from SINOTECH Machinery Co., Ltd. They offer free drawing services and can help you match your loader bushing, excavator bushing, or bucket pin to your machine.
