When it comes to maintaining and repairing construction equipment like the Komatsu PC120 excavator, one aspect that often gets overlooked is the windshield. A cracked or damaged windshield can severely impair visibility and safety, making timely replacement a crucial task. In this article, we will delve into the process of replacing the windshield on a Komatsu PC120 excavator, discuss common challenges, and provide practical advice to ensure that the replacement is done correctly.
Why Replace the Windshield on the Komatsu PC120 Excavator?
The windshield of any excavator serves more than just an aesthetic purpose—it is a vital component that ensures safety and protection. For a machine like the Komatsu PC120, which operates in rough environments and faces debris from construction sites, the windshield can take a lot of damage over time. Cracks, chips, or full breakage not only compromise visibility but also increase the risk of injury to the operator.
Replacing the windshield promptly can save time and money by preventing further damage to other parts of the excavator. Furthermore, keeping the windshield in top condition ensures that the operator can work safely, reducing the likelihood of accidents that could arise from poor visibility.
Steps for Replacing the Windshield on a PC120 Excavator
Replacing the windshield on a Komatsu PC120 may seem daunting, but with the right tools and a clear step-by-step guide, it can be done effectively. Below is a simplified approach to replacing the windshield:
1. Gather the Necessary Tools and Materials
Before starting the replacement process, make sure you have all the tools and materials you’ll need, including:
The first step in replacing the windshield is to remove the damaged one. This involves carefully detaching the frame or glass from the excavator’s cab. The windshield may be held in place by a combination of bolts, screws, and adhesive.
Once the old windshield has been removed, you’ll need to clean the area where the new windshield will be installed. Use a vacuum cleaner to remove any debris, dirt, or broken glass. It's also a good idea to scrape away any remaining old adhesive.
Now that the area is clean and prepped, it’s time to install the new windshield.
After the windshield is installed, it’s important to allow the adhesive or sealant to cure and set for the recommended amount of time. This ensures that the windshield is properly sealed and can withstand the harsh conditions of construction sites.
After the adhesive has set, test the windshield for any movement or gaps. Make sure it is securely attached to the frame and that there are no air leaks or water infiltration.
While replacing a windshield on a Komatsu PC120 is not a complicated process, it does come with some challenges. Here are a few common issues that might arise, along with solutions:
1. Difficulty Removing the Old Windshield
Sometimes, old adhesive can be difficult to remove, especially if it has hardened over time. If you find it difficult to scrape off the adhesive, consider using a heat gun to soften the material. Be careful not to overheat the area and damage the frame.
2. Misalignment of the New Windshield
If the new windshield is misaligned during installation, it could cause issues with visibility or may not fit properly. Take your time to ensure the windshield is aligned correctly before securing it. If needed, have a second person assist with positioning the windshield.
3. Incorrect Adhesive
Using the wrong type of adhesive can lead to issues with the windshield’s seal and security. Always use an adhesive that is specifically designed for windshield installation. Using the correct product will ensure the windshield remains secure in all conditions.
Conclusion
Replacing the windshield on a Komatsu PC120 excavator is an essential part of maintaining the safety and functionality of the machine. By following the proper steps for removal, cleaning, and installation, you can ensure that your new windshield is securely in place and provides the operator with clear visibility.
Regular maintenance and timely replacement of components like the windshield will help prolong the life of your excavator and reduce the likelihood of more expensive repairs down the line. As with all maintenance tasks, it’s important to take your time, use the right tools, and adhere to safety precautions.

Replacing the windshield on a Komatsu PC120 may seem daunting, but with the right tools and a clear step-by-step guide, it can be done effectively. Below is a simplified approach to replacing the windshield:
1. Gather the Necessary Tools and Materials
Before starting the replacement process, make sure you have all the tools and materials you’ll need, including:
- Replacement windshield (make sure it’s specifically for the PC120 model)
- Wrenches and screwdrivers
- Sealant or adhesive
- A scraper for old adhesive
- Safety gloves and goggles
- A vacuum cleaner to clean any debris
The first step in replacing the windshield is to remove the damaged one. This involves carefully detaching the frame or glass from the excavator’s cab. The windshield may be held in place by a combination of bolts, screws, and adhesive.
- Start by removing any screws or bolts that are securing the windshield.
- Use a scraper to gently lift and remove the adhesive or sealant that has bonded the windshield to the frame.
- If the windshield is cracked or broken, make sure to wear gloves and handle the glass carefully to avoid injury.
- Once the adhesive is loosened and the bolts removed, carefully remove the windshield from its frame.
Once the old windshield has been removed, you’ll need to clean the area where the new windshield will be installed. Use a vacuum cleaner to remove any debris, dirt, or broken glass. It's also a good idea to scrape away any remaining old adhesive.
- Clean the frame thoroughly to ensure a smooth and secure fit for the new windshield.
- If there is any corrosion or damage to the frame, it’s important to address that now. Repairing any minor damage before proceeding with the installation will help ensure the new windshield sits properly.
Now that the area is clean and prepped, it’s time to install the new windshield.
- Apply a thin layer of sealant or adhesive around the edges of the frame where the windshield will rest. Be careful not to use too much, as excess adhesive can spill out and create a mess.
- Position the new windshield carefully, ensuring that it aligns properly with the frame and the mounting points.
- Press the windshield gently into place, allowing the adhesive to bond and the windshield to secure itself in place.
- Once the windshield is properly positioned, replace any bolts or screws that hold the windshield in place. Tighten them to ensure the windshield is firmly secured.
After the windshield is installed, it’s important to allow the adhesive or sealant to cure and set for the recommended amount of time. This ensures that the windshield is properly sealed and can withstand the harsh conditions of construction sites.
- Most adhesives require about 24 hours to fully set, but refer to the manufacturer’s instructions for the specific curing time.
- During this time, avoid operating the excavator or putting any pressure on the windshield.
After the adhesive has set, test the windshield for any movement or gaps. Make sure it is securely attached to the frame and that there are no air leaks or water infiltration.
- Check for proper visibility from the operator's seat to ensure that the windshield does not obstruct their view.
- If necessary, clean the new windshield with appropriate cleaning agents to remove any smudges or fingerprints.
