Case 1835B Skid Steer Loader: Troubleshooting and Maintenance Insights

[MikePhua]

The Case 1835B skid steer loader, produced from the mid-1980s to the early 1990s, remains a reliable workhorse for various applications, including construction, landscaping, and agriculture. However, like any aging equipment, it is prone to certain mechanical issues. This article delves into common problems faced by 1835B owners, offering insights into potential causes and solutions.
Engine and Electrical System Challenges
One prevalent issue with the Case 1835B is starting difficulties, particularly with diesel models. Users have reported that the starter solenoid often fails to receive adequate power due to undersized wiring and excessive connections. This voltage drop can prevent the solenoid from activating, leading to starting problems.
Additionally, the engine's fuel system can be a source of concern. For instance, some owners have experienced white smoke emissions and power loss after a short period of operation. In one case, after rebuilding the injector pump and installing new injectors, the machine ran well initially but soon began emitting white smoke and losing power.
Hydraulic System Failures
Hydraulic issues are another common problem with the 1835B. Sudden loss of hydraulic function, such as the inability to raise the bucket or operate the lift arms, has been reported. In many instances, this failure is attributed to a broken shaft within the hydraulic pump, often caused by a pump failure that locks up and breaks the shaft.
Another hydraulic concern involves the auxiliary hydraulics not functioning properly. For example, when attempting to operate a broom attachment, the auxiliary hydraulics failed to activate, despite the main functions working correctly.
Drive System Issues
The drive system of the 1835B can also present challenges. Some users have noted that the left drive motor stalls under load, while the right side operates normally. This issue is often due to air trapped in the hydraulic lines or a faulty drive motor. Ensuring proper bleeding of the hydraulic system and inspecting the drive motor for wear can help resolve this problem.
Maintenance Tips and Recommendations
To maintain the Case 1835B in optimal condition, consider the following maintenance practices:

• Electrical System: Regularly inspect and clean battery terminals, replace worn wiring, and ensure all connections are secure to prevent starting issues.
  
• Fuel System: Monitor for signs of white smoke or power loss, which may indicate injector pump or fuel system problems. Address these promptly to avoid engine damage.
  
• Hydraulic System: Check hydraulic fluid levels regularly and inspect for leaks. Replace worn or damaged components to maintain hydraulic performance.
  
• Drive System: Bleed the hydraulic system to remove air pockets and inspect drive motors for wear. Regular maintenance can prevent drive-related issues.
  

By adhering to these maintenance practices, owners can extend the lifespan of their Case 1835B skid steer loader and ensure reliable performance for years to come.
