The Bobcat S220 skid steer is a popular model known for its compact size, strong lifting capacity, and versatility in various construction, landscaping, and agricultural applications. However, like all machinery, the S220 can experience technical issues that impact its performance. One common issue reported by users is the bucket tilt function leaking down, which can reduce productivity and even cause operational hazards if not addressed. This article explores the causes of bucket tilt leaks, how to troubleshoot the issue, and effective solutions to restore proper function.
Overview of the Bobcat S220 Skid Steer
Bobcat is a renowned manufacturer of skid steer loaders and compact equipment. The Bobcat S220, introduced as part of the company’s S-series, features a 74 horsepower engine and an operating capacity of 2,200 lbs, making it suitable for a wide range of tasks. The S220 is equipped with advanced hydraulic systems, which allow it to operate various attachments, including the bucket tilt, with ease. However, hydraulic issues like leaking bucket tilt can arise over time.
The bucket tilt function on a skid steer is part of the overall hydraulic system that controls the tilting motion of the bucket, allowing the operator to dump materials or adjust the bucket's angle during work. When this system fails or begins to leak, it can cause significant problems with the loader's operation.
Understanding Hydraulic Systems and Bucket Tilt
Hydraulic systems use pressurized fluid to transfer force, enabling machinery to perform tasks like lifting, tilting, and pushing. The Bobcat S220 utilizes a hydraulic pump to supply pressure to cylinders connected to various attachments, including the bucket tilt. These hydraulic cylinders are responsible for lifting and tilting the bucket during operation.
The bucket tilt system consists of a hydraulic cylinder, hoses, and control valves. The cylinder controls the motion of the bucket, while the hoses and valves ensure that hydraulic fluid flows to the appropriate areas, either lifting or tilting the bucket.
When a bucket tilt leaks down, it typically indicates a failure within one or more of these components, causing the hydraulic fluid to lose pressure, resulting in the bucket’s descent.
Common Causes of Bucket Tilt Leaks
There are several common reasons why the bucket tilt may leak down on the Bobcat S220, including:
To effectively troubleshoot and resolve the issue of a leaking bucket tilt, a methodical diagnostic approach is necessary. The following steps can help pinpoint the cause of the problem:
Once the source of the bucket tilt leak is identified, the following solutions can help fix the issue:
To prevent future bucket tilt leaks on the Bobcat S220, regular maintenance is essential. Here are a few preventive steps:
The Bobcat S220 skid steer’s bucket tilt system is a crucial component for various lifting and dumping tasks. However, like all hydraulic systems, it is prone to leaks and malfunctions due to wear, contamination, or faulty components. By diagnosing the source of the leak, taking appropriate action to repair or replace damaged parts, and performing regular maintenance, operators can extend the lifespan of the bucket tilt system and maintain the machine’s overall performance. Proper care and attention will ensure that the Bobcat S220 continues to perform at its best on every job.

Common Causes of Bucket Tilt Leaks
There are several common reasons why the bucket tilt may leak down on the Bobcat S220, including:
- Worn or Damaged Hydraulic Seals
Hydraulic seals prevent fluid from leaking out of cylinders, valves, and hoses. Over time, these seals can wear down or become damaged due to the constant pressure and movement in the hydraulic system. If the seals around the bucket tilt hydraulic cylinder are damaged, hydraulic fluid will leak, causing the bucket to gradually lower.
- Faulty or Leaking Hydraulic Cylinder
A damaged or worn-out hydraulic cylinder can result in the slow or sudden release of hydraulic fluid. This could cause the bucket to tilt or drop unexpectedly, making the system unreliable.
- Contaminated Hydraulic Fluid
Contaminants like dirt, debris, or moisture in the hydraulic fluid can affect the efficiency of the entire hydraulic system. Contaminated fluid can cause wear on seals, valves, and cylinders, contributing to leaks. Regular fluid maintenance is essential to keeping the hydraulic system in optimal condition.
- Air in the Hydraulic System
Air can enter the hydraulic system through loose connections, worn seals, or improper fluid filling. When air becomes trapped in the system, it can cause fluctuations in hydraulic pressure, which can lead to the bucket tilting or sinking over time.
- Faulty Control Valve
The control valve directs hydraulic fluid to the appropriate components, including the bucket tilt. If the valve is malfunctioning or leaking, it can result in poor pressure regulation and cause the bucket tilt to leak down.
To effectively troubleshoot and resolve the issue of a leaking bucket tilt, a methodical diagnostic approach is necessary. The following steps can help pinpoint the cause of the problem:
- Check Hydraulic Fluid Levels
Ensure that the hydraulic fluid is at the correct level. Low fluid levels can cause irregular pressure in the system, leading to leaks or insufficient performance. If the fluid level is low, top it off and check for any signs of leakage around the system.
- Inspect the Hydraulic Cylinder for Leaks
Check the hydraulic cylinder for any visible signs of fluid leakage. Leaking fluid around the seals or cylinder barrel is a strong indicator that the cylinder needs repair or replacement. If the cylinder is intact, check the connection points to ensure there are no loose fittings.
- Examine the Hydraulic Hoses and Fittings
Inspect the hoses and fittings connected to the bucket tilt hydraulic system for leaks or damage. Hoses can wear out or get pinched, leading to fluid loss. Ensure all connections are tight, and there are no visible cracks or wear in the hoses.
- Look for Contaminants in the Hydraulic Fluid
Check the hydraulic fluid for signs of contamination. If the fluid appears cloudy, dirty, or has visible particles, it is crucial to replace it with fresh fluid and clean the system. Contaminated fluid can lead to more serious issues within the hydraulic components.
- Test the Control Valve
The control valve should be tested to ensure it is directing fluid properly to the bucket tilt system. If the valve is not functioning correctly, it may need to be replaced or repaired.
Once the source of the bucket tilt leak is identified, the following solutions can help fix the issue:
- Replace Worn Hydraulic Seals
If the seals are worn or damaged, replace them with new, high-quality seals. Be sure to follow the manufacturer’s instructions for seal replacement to ensure a proper fit and prevent future leaks.
- Repair or Replace the Hydraulic Cylinder
If the hydraulic cylinder is leaking or damaged, it may need to be either repaired or replaced. In many cases, the cylinder can be rebuilt by replacing seals and other internal components, but if the damage is extensive, a full replacement may be required.
- Flush and Replace Contaminated Hydraulic Fluid
If the fluid is contaminated, it is essential to flush the hydraulic system thoroughly and replace the old fluid with clean, high-quality hydraulic oil. Be sure to clean any filters and replace them if necessary.
- Bleed the Hydraulic System
If air is trapped in the hydraulic system, it must be bled out. This can be done by loosening a bleed valve on the system, allowing trapped air to escape. Be sure to top off the fluid afterward to ensure proper pressure.
- Repair or Replace the Control Valve
If the control valve is leaking or malfunctioning, it may need to be repaired or replaced. Consult the manufacturer’s manual for specific instructions on diagnosing and fixing control valve issues.
To prevent future bucket tilt leaks on the Bobcat S220, regular maintenance is essential. Here are a few preventive steps:
- Check fluid levels regularly to ensure the system is properly lubricated and pressurized.
- Inspect hydraulic hoses and cylinders for wear, cracks, or damage.
- Use clean, high-quality hydraulic fluid and change it at recommended intervals.
- Clean and replace filters to prevent contaminants from damaging the system.
- Tighten all hydraulic fittings to prevent leaks from loose connections.
