Skid steers like the Bobcat 773 are critical pieces of equipment in many industries, ranging from construction to landscaping. These compact machines provide versatility, agility, and power, making them indispensable on the job site. However, like all machinery, they are subject to wear and tear, and one of the more common issues encountered is the failure of the drive chain. A broken front left side chain, as experienced by an operator, is one such problem that demands timely attention to ensure the machine's continued operation.
Understanding the Role of the Drive Chain
The drive chain in a skid steer is responsible for transmitting power from the engine to the wheels or tracks, allowing the machine to move. In models like the Bobcat 773, the front-left side chain is part of a larger system of chains, sprockets, and drive components that work in tandem to provide the necessary power to maneuver the machine. If one of these chains breaks or fails, it can lead to a loss of mobility or even cause further damage to other components if not addressed quickly.
What Happens When a Front Left Side Chain Breaks?
When the front left-side chain on a Bobcat 773 breaks, the machine may experience a reduction or complete loss of power to the wheel or track on that side. This can make the skid steer difficult or even impossible to operate until the issue is resolved. The machine may pull unevenly, making it challenging to control or maneuver, which can slow down work and pose a safety risk.
A broken chain can also indicate that other components might be under strain or at risk of failure. Over time, regular wear on the chain, lack of proper maintenance, or even improper use can contribute to the failure of key parts.
Steps to Repair a Broken Front Left Side Chain
Several factors can lead to the breakage of a drive chain in a skid steer. Some of the most common causes include:
To prevent issues like a broken front left side chain in the future, it’s essential to stay on top of maintenance. Here are some helpful tips:
One seasoned operator recalled an instance where a front-left side chain broke on a Bobcat 773 while on a critical job site. The machine had been operating for several hours under heavy load when the chain snapped, halting progress and causing delays. The operator had to perform the repair on-site, which, while possible, took longer due to the lack of proper tools and a stable work environment. This experience highlighted the importance of carrying spare parts and tools, especially when operating in remote locations.
Another operator shared a story of how consistent maintenance had helped extend the life of the chains on their machine. By sticking to a regular schedule of lubrication, tension checks, and component inspections, they were able to avoid major breakdowns and keep their Bobcat 773 running smoothly for years.
Conclusion: Timely Repair and Maintenance Are Key
A broken front-left side chain on a Bobcat 773 can be a frustrating issue, but with proper knowledge, tools, and preparation, it is entirely manageable. Regular maintenance and timely repairs are key to keeping your skid steer in top working condition. By staying vigilant and addressing issues before they escalate, operators can ensure their equipment continues to perform reliably and efficiently on the job site.

Steps to Repair a Broken Front Left Side Chain
- Safety First: Before starting any repair, ensure the machine is turned off and securely positioned. Disconnect the battery to prevent accidental starts, and engage any parking brakes if applicable.
- Lift the Skid Steer: Use a suitable lifting mechanism, such as a jack or hoist, to elevate the front end of the machine. This provides enough clearance to safely work on the drive chain and inspect any other components that may need attention.
- Remove the Old Chain: Once the machine is lifted and stabilized, you’ll need to remove the damaged front-left side chain. This process may involve removing the chain covers, disconnecting the chain from the sprockets, and taking out any additional hardware that holds the chain in place.
- Inspect Related Components: It’s essential to inspect the sprockets, bearings, and other drive components for wear. If these parts are worn out or damaged, it may be necessary to replace them before installing the new chain. Replacing just the chain without addressing other damaged components may lead to premature failure of the new chain.
- Install the New Chain: After inspecting and replacing any necessary components, install the new chain. Ensure that the chain is properly tensioned according to the manufacturer’s specifications. Over-tightening or under-tightening the chain can cause further issues down the line.
- Test the Repair: Once the new chain is installed, lower the skid steer back to the ground, reconnect the battery, and perform a test run. Check for smooth operation and listen for any unusual sounds that might indicate a problem with the repair.
Several factors can lead to the breakage of a drive chain in a skid steer. Some of the most common causes include:
- Wear and Tear: Over time, the constant movement of the chain, coupled with exposure to dirt, dust, and debris, can cause it to wear down. Chains that are not regularly lubricated can also wear more quickly.
- Improper Tension: If the chain is too loose or too tight, it can increase the risk of failure. A loose chain can slip off the sprockets, while an overly tight chain can put excessive strain on the components.
- Overloading: Using the skid steer for tasks beyond its rated capacity can put additional stress on the drive system, leading to premature chain failure.
- Improper Installation: If the chain is not properly aligned during installation, it may cause uneven wear and eventual breakage.
To prevent issues like a broken front left side chain in the future, it’s essential to stay on top of maintenance. Here are some helpful tips:
- Regular Lubrication: Ensure the drive chain is well-lubricated to reduce friction and wear. Regularly check and apply the recommended lubricant to all moving parts.
- Monitor Tension: Periodically check the chain tension and adjust as necessary to keep it within the manufacturer’s specifications.
- Inspect Components: Regularly inspect the drive components, including the chain, sprockets, bearings, and shafts. Replacing worn or damaged parts early can prevent further issues down the road.
- Follow Load Limits: Avoid overloading the skid steer to reduce strain on the chain and drive system.
