Cleaning Up and Painting a Link-Belt 86100: A Step-by-Step Guide to Restoring Your Excavator

[MikePhua]

Restoring an old excavator like the Link-Belt 86100 can be a rewarding project for heavy equipment owners. Not only does it extend the life of the machine, but it also enhances its aesthetics, improving both its performance and resale value. While the mechanical aspects of such a project are often the main focus, cleaning and painting the equipment can significantly boost its functionality, protect against rust, and help maintain its appearance. In this guide, we will discuss the best practices for cleaning and painting your Link-Belt 86100, detailing each step for a professional finish.
Why Clean and Paint Your Link-Belt 86100?
Cleaning and painting a heavy machine like the Link-Belt 86100 does more than just improve its looks. There are several key reasons for undertaking this restoration:

• Rust Prevention: Exposed metal parts of the excavator are prone to rusting, especially in areas with high humidity or frequent exposure to water. A good cleaning and paint job protects metal surfaces from corrosion.
  
• Improved Durability: A well-applied paint layer helps to protect the equipment from dirt, grime, chemicals, and extreme weather conditions. It also helps to preserve parts that are harder to replace, such as structural components.
  
• Resale Value: A machine that looks well-maintained and clean can command a higher resale value.
  
• Enhanced Aesthetics: Keeping the equipment looking fresh and clean boosts its overall appearance, giving the operator a sense of pride in their machine.
  

Step 1: Preparation and Safety Measures
Before beginning the cleaning and painting process, proper preparation is critical. This ensures the job is done effectively and safely. Here’s how to prepare:
Tools and Materials Needed:

• Pressure washer or hose
  
• Degreaser (preferably a biodegradable option)
  
• Scrub brushes (stiff and soft bristles)
  
• Paint scraper or wire brush
  
• Sandpaper (various grit sizes)
  
• Paint (specifically designed for heavy equipment)
  
• Masking tape and plastic sheeting
  
• Respirator mask and safety goggles
  
• Gloves
  
• Ladder or scaffolding (if necessary)
  

Safety First:
Wear protective gloves, goggles, and a respirator mask throughout the process. Heavy machinery cleaning often involves working with chemicals or inhaling particles, so proper ventilation and safety equipment are crucial.
Step 2: Cleaning the Excavator
The first step in restoring your Link-Belt 86100 is cleaning the machine thoroughly. This removes dirt, grease, and debris that could interfere with the painting process. Here’s a step-by-step guide to cleaning:
1. Wash the Exterior:
Use a pressure washer to rinse off large dirt particles and mud. If a pressure washer is not available, a hose and scrub brush will also suffice. Be sure to get into all the nooks and crannies where dirt can accumulate, such as:

• The undercarriage
  
• Around the tracks and wheels
  
• The joints and moving parts of the arms and boom
  
• The engine compartment
  

2. Apply Degreaser:
Once the machine is wet, apply a degreaser to areas that are oily or greasy. The engine compartment, hydraulic lines, and any other areas with accumulated grease should be targeted. Let the degreaser sit for a few minutes, then scrub the surfaces with a stiff-bristled brush.
3. Rinse and Dry:
After scrubbing, rinse off the degreaser and dirt thoroughly. Use a hose or pressure washer to ensure the grease is completely removed. After washing, allow the equipment to dry completely. This is important, as any residual moisture could interfere with the paint’s adhesion.
4. Scrape Off Old Paint (If Necessary):
If the equipment has peeling or chipped paint, use a paint scraper or wire brush to remove the old, damaged paint. This will provide a clean, smooth surface for the new paint to adhere to.
Step 3: Sanding the Surfaces
Sanding is an essential step in preparing the surface for painting. It helps to smooth out any imperfections and provides better adhesion for the paint. Here's how to proceed:

• Choose the Right Sandpaper: Start with coarse-grit sandpaper (around 80 grit) to remove rough patches or rust. Follow this up with finer grit sandpaper (220-320 grit) to smooth out the surface. For areas with stubborn rust, a wire brush can help remove the bulk of it before sanding.
  
• Focus on Problem Areas: Pay extra attention to areas that are prone to rusting, such as the undercarriage, hydraulic lines, and the joints where metal parts meet.
  
• Clean the Sanded Areas: After sanding, wipe down the machine with a clean cloth to remove any dust and debris from the sanding process. This ensures a smooth, clean surface for the paint.
  

Step 4: Masking and Preparing for Paint
Before you begin painting, you’ll need to mask off areas that shouldn’t be painted. This could include windows, mirrors, hydraulic hoses, and any other parts that are sensitive to paint.

• Use Masking Tape: Apply masking tape to areas such as the edges of the windows, lights, and other non-paintable areas. Be meticulous in ensuring the tape is applied straight to avoid any unwanted paint lines.
  
• Cover Sensitive Areas: Use plastic sheeting or drop cloths to cover any areas of the machine that are especially sensitive to paint, such as electrical components or the engine compartment.
  

Step 5: Painting the Link-Belt 86100
Now that the machine is prepped, it’s time to apply the paint. Choosing the right paint and applying it correctly is critical for achieving a professional finish.
1. Select the Right Paint:
Use paint that is specifically designed for heavy equipment. These paints are durable, weather-resistant, and designed to withstand the harsh conditions that machines like the Link-Belt 86100 face. Oil-based enamel paint or polyurethane-based paint is commonly used for heavy machinery restoration.
2. Apply the Paint in Layers:

• First Coat: Start by applying a thin, even coat of primer (if necessary) to ensure proper paint adhesion. After the primer dries, apply the first coat of color.
  
• Multiple Coats: Apply at least two coats of paint for optimal durability. Allow each coat to dry completely before applying the next.
  
• Use Proper Technique: Use a spray gun for even coverage, or use a roller or brush for smaller areas. Always work in a well-ventilated area and follow the paint manufacturer’s instructions.
  

3. Let the Paint Dry:
Allow the paint to dry thoroughly before using the equipment. The drying time depends on the type of paint used, so refer to the manufacturer’s guidelines.
Step 6: Finishing Touches
Once the paint has dried, inspect the machine for any areas that might need touch-ups. After ensuring that everything is properly painted, remove the masking tape and plastic sheeting.

• Polish: For a glossy, smooth finish, consider applying a clear coat of polyurethane to protect the paint and give it an extra shine.
  
• Reassemble and Test: If any parts were removed during the painting process (such as lights or mirrors), reassemble them carefully. Conduct a full inspection of the machine to ensure everything is functioning properly.
  

Conclusion
Cleaning and painting a Link-Belt 86100 is a rewarding task that can significantly enhance the machine’s appearance, performance, and lifespan. By following these steps and using the proper tools and materials, you’ll restore your excavator to its former glory. Whether you’re looking to improve its functionality, prepare it for resale, or simply give it a fresh new look, investing time and effort into the restoration process is always worthwhile. With a well-maintained machine, you can extend its useful life and keep it performing at its best for years to come.
