Introduction
The Bobcat T320, like many skid steer loaders, relies on its hydraulic system for efficient movement and operation of attachments. However, hydraulic issues can sometimes arise, leading to decreased performance or even a complete operational failure. One such issue reported with the Bobcat T320 is a hydro issue, where the machine fails to perform as expected. This article will cover common causes of hydraulic issues on the T320 and possible solutions to address them.
Identifying the Problem
Hydraulic problems can manifest in several ways, such as sluggish operation, weak lifting capacity, or unresponsiveness in certain functions. When a Bobcat T320 experiences a hydro issue, the following symptoms are commonly observed:
Hydraulic issues on the Bobcat T320 can be caused by several factors, ranging from low fluid levels to more complex pump or valve failures. By following the troubleshooting steps outlined in this article, operators can identify and resolve the issue, restoring the machine’s performance. Regular maintenance, including fluid checks, filter replacements, and hose inspections, is key to preventing future hydraulic problems and ensuring the machine operates at its best.
If the problem persists after performing these checks and repairs, it’s advisable to seek professional help from a qualified technician. Addressing hydraulic issues early can prevent more costly and severe damage in the future, keeping the Bobcat T320 running efficiently for years to come.

Identifying the Problem
Hydraulic problems can manifest in several ways, such as sluggish operation, weak lifting capacity, or unresponsiveness in certain functions. When a Bobcat T320 experiences a hydro issue, the following symptoms are commonly observed:
- Slow or weak lifting of the bucket or arm
- Difficulty with hydraulic attachment operation
- Uneven or jerky movement during operation
- Complete lack of response from the hydraulics in extreme cases
- Low Hydraulic Fluid
One of the most common causes of hydraulic issues is low hydraulic fluid levels. When the fluid level drops too low, the hydraulic pump can’t generate enough pressure to move the loader’s arms, operate attachments, or perform other functions. Always ensure that the hydraulic fluid is topped off to the recommended level. Regular checks should be part of routine maintenance to avoid this issue.
- Hydraulic Pump Malfunction
The hydraulic pump is the heart of the hydraulic system, generating the necessary pressure for fluid movement. If the pump is failing or malfunctioning, it can lead to weak or no hydraulic power. Common symptoms of a bad pump include sluggish movement or complete lack of hydraulic response. A pump failure will often require professional repair or replacement.
- Clogged Hydraulic Filters
Over time, dirt, debris, and other contaminants can clog the hydraulic filters, restricting the flow of fluid and causing a drop in pressure. A clogged filter can lead to sluggish or weak hydraulic performance. Regularly replacing or cleaning the hydraulic filters is essential for maintaining optimal fluid flow and preventing issues.
- Air in the Hydraulic Lines
Air can enter the hydraulic system if there’s a leak in the hoses or fittings. This trapped air can cause erratic or inconsistent hydraulic performance, including jerky movements or a loss of pressure. Identifying and repairing the source of air leaks is crucial in resolving this issue.
- Hydraulic Hose or Fitting Leaks
A leak in any of the hydraulic hoses or fittings can cause a loss of pressure in the system. Leaks can often be identified by inspecting the hoses for signs of fluid loss, such as wet spots or discoloration. If a leak is found, the affected hose or fitting must be replaced or repaired.
- Check Hydraulic Fluid Levels
Start by inspecting the hydraulic fluid level. If it is low, add the appropriate type of fluid until it reaches the recommended level. Ensure that the machine is on level ground when checking the fluid to get an accurate reading.
- Inspect for Leaks
Check the hydraulic hoses and fittings for any signs of leaks or damage. Look for wet spots or oil stains around the hoses, fittings, or pump. If a leak is found, the affected part will need to be replaced or repaired.
- Replace Hydraulic Filters
If the filters are clogged or dirty, replace them with new filters. This is a relatively simple maintenance task that can be performed by the operator or a mechanic. Replacing the filters can improve fluid flow and restore hydraulic power.
- Bleed the System
If air is suspected in the hydraulic system, bleed the system to remove the trapped air. This process involves loosening a fitting or valve to allow air to escape. Be cautious when performing this procedure to avoid injury or further damage.
- Test the Hydraulic Pump
If the fluid levels are adequate, no leaks are found, and the filters are clean, but the issue persists, the hydraulic pump may need to be inspected. A qualified technician will be able to test the pump’s pressure and determine whether it needs repair or replacement.
- Check for Fault Codes
Many modern Bobcat machines, including the T320, are equipped with onboard diagnostic systems that can help identify the cause of the problem. Use the diagnostic tool to check for any fault codes related to the hydraulic system. This can help pinpoint issues with the pump, valves, or other components.
