What are the Common Case 1840 Problems?
While the Case 1840 has a reputation for durability, it’s essential to acknowledge that, like any machinery, it can encounter occasional issues. Nevertheless, staying informed about potential hiccups that Case 1840 may develop remains crucial.
1. Starting Problem
The skid steer starting problem is one of the frustrating ones. Possible causes include a clogged fuel system, incorrect voltage in the battery, and loose connections. Also, if the fluid level is poor, your Case 1840 skid steer will not start.
- Clogged Fuel System
The carburetor is an essential component of the fuel system. It balances the fuel and air ratio in the engine. Ignition will only happen properly if the ratio is balanced.
Outside airflow fails to enter the system when there is a blockage in the fuel system. As a result, oil won’t participate in the ignition process and the engine.
Inspect the whole fuel system. Make sure no clog or blockage is there. Also, the fluid level must meet the manufacturer’s recommended level.
- Loose Connections
Loose or corroded connection cables are another common reason for Case 1840 starting problems. Your skid steer may not get enough juice from the battery and fail to start. Moreover, you can experience unreliable or erratic performance from your skid steer.
Fortunately, the solution is straightforward.
All you need to do is check the cable for loose connections, and if you find any, ensure well-tightening.
- Low Voltage in the Battery
The starting problem is evident if the battery is weak or dead. In fact, the battery can’t charge because of a bad alternator.
In such a case, it is essential to check the alternator condition. Replace it if needed.
On the other hand, if the alternator is not the culprit, ensure proper battery charging. Also, maintaining the correct voltage is essential.
2. Hydraulic Problem
Hydraulic powers the skid steer arms. This means that Case 1840 hydraulics generate the necessary pressure to lift a load. However, loss of power in the arms is a common issue for every utility tractor. If your Case 1840 fails to lift a load efficiently, be sure there is something wrong with the hydraulics.
A leak in the main feed line is the primary culprit. The hydraulics fail to maintain proper pressure when a leak appears in the line. Thus, Case 1840 can’t lift the load or arm.
The following steps will help you sort out the problem.
- Step 01: Check the fluid level of the hydraulic. Top the fluid if the level is low.
- Step 02: Look for a hydraulic fluid leak by removing the floor pan. Replace the main feed line if it is blown. Avoid replacing as the leak may reappear due to the fluid pressure.
- Step 03: Examine the cylinder bushings to know if they are cracked or worn. Bad bushing may leave damage or scratches on the cylinder rod. In this case, replacing the damaged bushing is the best solution. Call a professional mechanic to handle the task since it is complicated.
3. Stubborn Parking Brake
This minor problem in Case 1840 will surely annoy you. Sometimes, you must put much effort into releasing the parking brake.
The pin brake system is responsible for the issue. Generally, the pin disconnects when there is tension on it from the gear. If the pin fails to disconnect, a stubborn parking brake error appears.
The solution to the issue still needs to be fixed. The error is an outcome of the skid steer design. According to the Case 1840 users, they drive the utility tractor back and forth. Fortunately, it helps them to release the parking brake since the pin comes free by relieving the tension.
4. Drive Chain
Driving any skid steer is prohibited and is no exception for Case 1840. Otherwise, the drive chain of your Case 1840 can get stretched. Moreover, driving on hard surfaces can also cause chain stretching.
A stretched drive chain is the prime reason for the utility tractor’s loss of power and sluggish movement. At the same time, you will face difficulty in driving the Case 1840 on slopes or bumps. Overall, your machine’s performance will be hindered.
Solve the problem by following the below steps.
- Step 01: Access the drive chain by unbolting the chain case cover. You will find the cover on the side of the skid steer between the wheels.
- Step 02: Place a pan beneath the cover, as the chain case is usually filled with oil. The pan will help you catch the oil.
- Step 03: Check the tension of the chain. If it is loose, adjust the tension.
- Step 04: Also, look for damage in the chain. Replacing the chain will be best if it is severely damaged. Moreover, the chain case catches a lot of dust and debris. Clean them as much as possible.
5. Engine Problem
Although a few customers complained that they experienced engine problems, being aware will help you prevent errors easily.
If the Case 1840 engine delivers poor performance over time, consider checking the engine thoroughly. Here are the steps to follow.
- Step 01: Check and ensure no clog in the fuel system. Inspect the fuel filter, fuel lines, and fuel tank for dust and debris.
- Step 02: Examine the glow plugs for dirt or damage. Replace the defective glow plugs without fail.
- Step 03: Engine problem may appear for stretched, worn, or loose throttle cable. When the throttle cable is loose, you will notice poor acceleration. Replace or adjust the cable stretched or damaged cable.
6. Electrical Issues
The Case 1840 owner faced a perplexing electrical issue with their machine. The engine started when the safety bar was up but randomly shut off. Such erratic behavior must cause frustration on your job site.
A potential culprit is a malfunctioning fuel shut-off solenoid, which, if faulty, leads to sporadic shutdowns.
- Step 01: The seat switch wire can entangle the hydraulic levers beneath the seat. This simulated an “open switch” condition, disrupting the engine’s operation.
- Step 02: After addressing this wire problem and resolving the other issues, the tractor will run flawlessly for prolonged hours
