The Bobcat S185 is a popular skid steer loader known for its compact design and powerful performance. However, like any piece of machinery, it requires regular maintenance to ensure its efficiency and longevity. One of the key components that may need attention over time is the drive chain. If your 2003 Bobcat S185 is experiencing issues with its drive chains, such as slippage, excessive wear, or noise, it's essential to understand how to properly adjust or replace them. In this article, we'll cover how to adjust the drive chains on your Bobcat S185, potential causes of chain-related issues, and preventative measures to keep them running smoothly.
Understanding the Role of Drive Chains in the Bobcat S185
The drive chains on a Bobcat S185 are crucial for transmitting power from the engine to the wheels or tracks. These chains are a part of the machine's drivetrain, helping it move and perform tasks such as lifting, pushing, and digging. The chains are under significant tension during operation and must be maintained to ensure smooth, efficient movement. If the drive chains are too loose or too tight, it can cause a variety of performance issues, including reduced efficiency, premature wear, and even potential failure of the drivetrain components.
Signs of Drive Chain Issues
Before diving into the adjustment process, it's important to understand the signs that indicate your drive chains may need attention. Some common symptoms of drive chain problems include:
Adjusting the drive chains on the Bobcat S185 requires a few basic tools and a methodical approach. Here’s a step-by-step guide to help you adjust the drive chains properly:
1. Safety First
Before you start any maintenance work, always ensure that the skid steer is turned off, the key is removed, and the machine is on a level surface. If you're working on an elevated machine, make sure it's properly supported to prevent any accidents.
2. Locate the Drive Chains
The drive chains on the Bobcat S185 are typically located near the wheels or tracks. Depending on whether you have a wheeled or tracked version, the access point for the chains may vary. For the wheeled version, the chains are usually found behind the wheels, while for the tracked version, they are located near the tracks.
3. Inspect the Chains
Before attempting any adjustments, inspect the drive chains for visible signs of damage, wear, or rust. If you notice any damage, such as broken or severely worn links, it's a good idea to replace the chain instead of just adjusting it. Damaged chains can cause more serious issues down the line and could be a safety hazard.
4. Loosen the Tension
To adjust the drive chain, you'll need to loosen the tension. This is usually done by loosening the bolts on the tensioner or chain guard. Depending on the design of your Bobcat S185, you may need a wrench or socket set to loosen these bolts.
Once the bolts are loose, the tensioner can be moved to adjust the chain's tension. If the chain is too loose, it will need to be tightened; if it's too tight, it will need to be loosened.
5. Adjust the Tensioner
The Bobcat S185 is equipped with a tensioning system that allows you to adjust the chain’s tension. To tighten the chain, you can use the tensioning mechanism to shift it into a more taut position. On the other hand, if the chain is too tight, you may need to move the tensioner in the opposite direction to loosen the chain. It’s important to find the right balance, as a chain that is too tight can cause unnecessary wear on both the chain and the drivetrain components.
6. Re-tighten the Bolts
Once you've achieved the desired tension, re-tighten the bolts securing the tensioner. Make sure they are snug, but be careful not to overtighten, as this can cause damage to the bolts or the surrounding components.
7. Test the Machine
After making the adjustments, start the machine and perform a few test movements. Check for smooth operation, even movement on both sides of the machine, and listen for any unusual noises. If the problem persists, you may need to recheck the chain’s tension or inspect for other issues.
Common Problems with Bobcat S185 Drive Chains and How to Prevent Them
Even with proper adjustment, the drive chains on the Bobcat S185 can face some challenges. Below are some common issues and tips on how to prevent them.
1. Premature Wear
If the drive chains are experiencing premature wear, it could be due to several factors, such as improper tension, excessive load, or poor lubrication. To prevent this, always ensure that the chains are properly adjusted and lubricated. Periodically check the chains for wear and replace them when necessary to prevent further damage.
2. Rusting
Rust can cause chains to seize up or wear more quickly. To prevent rust, regularly clean the chains and apply a protective lubricant. If the machine is exposed to wet or salty conditions, consider using a rust-resistant lubricant to protect the chains.
3. Overloading the Machine
Consistently overloading the Bobcat S185 can place excessive stress on the drive chains, causing them to stretch or break. Be mindful of the weight limits specified by the manufacturer and avoid overloading the machine, especially when performing heavy lifting or pushing tasks.
4. Lack of Maintenance
Neglecting regular maintenance, such as cleaning the chains, checking the tension, and replacing worn-out components, can cause the drive chains to degrade faster. Establish a maintenance schedule based on the machine's usage and adhere to it to keep the drive system in top condition.
A Real-World Example: The Importance of Proper Chain Maintenance
A construction company operating a fleet of Bobcat S185 skid steer loaders found that one of their machines was experiencing inconsistent movement and excessive noise from the drive system. Upon inspection, it was discovered that the drive chains on the machine were excessively loose, causing the wheel on one side to slip and creating undue strain on the drivetrain. After tightening the chains and performing a thorough inspection, the machine returned to smooth operation. This simple maintenance task not only improved performance but also extended the life of the drive system, saving the company from costly repairs.
Conclusion
Proper maintenance of the drive chains on your Bobcat S185 is essential for ensuring smooth operation and preventing costly repairs. By understanding how to adjust the drive chains and addressing common issues like wear, rust, and overloading, you can keep your skid steer loader running at its best. Regular inspections and proper adjustments will not only improve the performance of the machine but also increase its lifespan, ultimately saving you time and money on repairs. Whether you’re using the Bobcat S185 for light landscaping or heavy construction work, maintaining the drive chains will help ensure that the machine continues to deliver optimal performance for years to come.
