The Gehl 7800 and 7810 skid steer loaders, renowned for their robust construction and versatility, have been integral to various industries, including construction, agriculture, and landscaping. However, operators have occasionally reported difficulties in achieving precise bucket movements, particularly when using the left-hand control lever. This article delves into the potential causes of this issue, offers diagnostic steps, and provides maintenance recommendations to enhance control precision.
Understanding the Control Mechanism
The Gehl 7800 and 7810 models are equipped with T-Bar control systems, where the left T-Bar manages drive functions, and the right T-Bar controls lift and tilt operations. Operators have noted that achieving fine, incremental bucket movements can be challenging, especially with the left-hand control. This difficulty is often attributed to the inherent design of the control system, which may not offer the same level of sensitivity as other machines, such as those from Bobcat or Caterpillar.
Potential Causes of Control Issues

1. Hydraulic System Limitations: The responsiveness of the bucket's movement is influenced by the hydraulic system's design and condition. If the hydraulic fluid is low or the system is contaminated, it can lead to sluggish or jerky movements. Regular maintenance, including checking fluid levels and replacing filters, is essential to ensure optimal performance.
   
2. Control Linkage Wear: Over time, the mechanical linkages connecting the control levers to the hydraulic valves can experience wear, resulting in play or resistance in the controls. Inspecting and lubricating these linkages can help restore smoother operation.
   
3. Operator Technique: Achieving fine control requires a delicate touch. Operators should practice gradual movements and avoid sudden inputs to maintain smooth bucket operation.
   

• Hydraulic Fluid Check: Regularly inspect the hydraulic fluid level and quality. Low or dirty fluid can impair system performance.
  
• Linkage Inspection: Periodically examine the control linkages for signs of wear or damage. Lubricate moving parts to reduce friction and improve response.
  
• Operator Training: Encourage operators to familiarize themselves with the machine's control sensitivity and practice fine movements to enhance proficiency.
  

Introduction: When a Trusted Backhoe Starts Throwing Codes
The JCB 3CX is a widely used backhoe loader known for its reliability in construction, agriculture, and utility work. But even dependable machines can develop faults—especially when electronic systems are bypassed or emissions components begin to fail. A 2014 JCB 3CX in Ireland recently presented two key issues: an immobilizer fault with code U191556 and an EGR-related fault P040000, accompanied by noticeable power loss. This article explores the meaning behind these codes, the risks of bypassing immobilizer systems, and how to address EGR-related performance problems.
Fault 1: U191556 – Invalid Key / Immobilizer Error
This fault code indicates that the machine’s electronic control unit (ECU) is rejecting the key signal. In this case, the immobilizer had previously been bypassed using a code workaround, which may have disrupted the ECU’s ability to authenticate the key properly.
Key components involved:

• Immobilizer Module: Prevents unauthorized engine start.
  
• Key Transponder: Sends a coded signal to the ECU.
  
• ECU (Engine Control Unit): Verifies key signal before allowing ignition.
  

• Bypassed immobilizer logic interfering with ECU communication.
  
• Corrupted or mismatched key transponder data.
  
• Software mismatch due to unauthorized reprogramming.
  

• Reprogram the ECU using official JCB diagnostic software.
  
• Replace or re-sync the key transponder with the immobilizer module.
  
• Avoid further bypass attempts, which may trigger additional faults or disable safety features.
  

• EGR Valve Sticking: Carbon buildup prevents proper valve movement.
  
• EGR Cooler Blockage: Restricts flow and causes overheating.
  
• Sensor Failure: Incorrect readings from EGR position or temperature sensors.
  
• Software Conflict: Mapping or tuning errors after ECU modification.
  

• Reduced throttle response.
  
• Black smoke under load.
  
• Increased fuel consumption.
  
• Engine derating (power reduction mode).
  

• Remove and clean the EGR valve and cooler.
  
• Replace faulty sensors and check wiring harness integrity.
  
• Use diagnostic software to test EGR valve actuation and flow rates.
  
• If emissions regulations allow, consider EGR delete mapping—but only with proper ECU tuning and legal compliance.
  

• Clean EGR components every 500–750 operating hours.
  
• Use low-sulfur diesel to reduce carbon buildup.
  
• Monitor fault codes regularly with a scan tool.
  
• Avoid prolonged idling, which accelerates EGR fouling.

Introduction to New Holland LX565 Antifreeze Leak Issues
The New Holland LX565 is a compact skid steer loader widely used in construction, landscaping, and agricultural applications. Like many machines with complex hydraulic and cooling systems, antifreeze leaks can occur, potentially signaling serious engine or cooling system issues. Antifreeze (coolant) leakage not only threatens machine reliability but also risks engine overheating and costly damage if left unaddressed.
This detailed guide explores common causes of antifreeze leaks on the LX565, diagnostic procedures, repair solutions, and preventive tips, enriched with real-world examples and maintenance advice to help owners keep their machines running optimally.
Common Causes of Antifreeze Leaks in New Holland LX565

• Engine Block Cracks
  Cracks in the engine block are a severe and often irreversible cause of coolant leaks. Vibrations, metal fatigue, or previous overheating can produce fine cracks that leak small amounts of antifreeze. This type of leak is challenging to repair and may require engine replacement or major machine rebuild.
  
• Damaged or Worn Seals and Gaskets
  Constant thermal cycling and age degrade gaskets (head gasket, intake manifold gasket) and seals (water pump seals, freeze plugs), allowing coolant to escape. Leaking gaskets usually lead to visible wetness around engine joints or dripping coolant under the machine.
  
• Radiator and Hose Issues
  Though less common if the radiator is intact, failing hoses, clamps, or radiator end tanks might leak antifreeze. Checking for hose cracks, loose clamps, or corrosion is essential.
  
• Water Pump Failure
  Water pump mechanical seal failure or bearing wear can cause coolant to leak near the pump housing area. Water pump issues sometimes result in overheating if the pump fails to circulate coolant properly.
  
• Overheating and Coolant Consumption
  Recurrent overheating due to antifreeze loss can worsen leaks by causing additional stress to engine parts. Monitoring engine temperature and performing timely coolant top-ups prevents severe damage.
  

• Visible puddles of green or orange antifreeze beneath the machine.
  
• Frequent need to add antifreeze to maintain coolant level.
  
• Engine temperature gauge rising above normal operating range.
  
• Steam or sweet-smelling vapor near the engine during operation.
  
• Decreased engine performance due to overheating.
  

• Visual Inspection
  Examine the engine block, radiator, hoses, water pump, and surrounding components for coolant residue or wetness.
  
• Pressure Testing Cooling System
  Applying pressure to the cooling system with a special tester identifies leaks and their exact location.
  
• Dye Testing
  Adding UV dye to the coolant and inspecting with a UV light helps pinpoint hard-to-see leaks.
  
• Check Engine Temperature Logs
  Monitoring for unusual temperature spikes or fluctuations during operation can indicate leak severity or secondary damage.
  

• Minor Seal and Gasket Replacement
  Replace worn gaskets and seals after cleaning mating surfaces to restore proper sealing.
  
• Block Crack Diagnosis and Repair
  Small cracks may sometimes be temporarily sealed with specialized chemical sealants, but this is not a guaranteed long-term fix. Welding or engine block replacement might be necessary in severe cases.
  
• Replace Water Pump or Hoses
  Change defective water pumps and hoses promptly to avoid further coolant loss and overheating.
  
• Coolant Flush and Replacement
  After repairs, flushing old coolant and filling with fresh antifreeze maintains effective cooling and corrosion protection.
  
• Use of RTV Sealants
  RTV silicone can aid in sealing joints, especially around bolts and flanges, but is not suitable as a standalone fix for major cracks.
  

• Regularly check coolant level and top off with manufacturer recommended antifreeze mix.
  
• Inspect radiator and hoses periodically for wear or damage.
  
• Maintain proper engine operating temperatures by keeping filters clean and coolant flowing.
  
• Avoid abrupt temperature changes (cold coolant on hot engines) to reduce thermal stress.
  
• Record maintenance and repairs to track machine health trends.
  

• Antifreeze/Coolant: Fluid that absorbs heat from the engine and dissipates it through the radiator, preventing freezing and overheating.
  
• Engine Block: The main structure of the engine housing cylinders and coolant passages.
  
• Water Pump: Circulates coolant through engine and radiator.
  
• Gasket: Sealing material placed between engine components to prevent fluid leakage.
  
• Radiator: Heat exchanger that cools the engine coolant.
  
• RTV Silicone: Room-temperature vulcanizing silicone sealant used for sealing joints and flanges.

Introduction: When the Basket Loses Its Balance
The Genie S45 telescopic boom lift is designed for precision and safety, with a self-leveling platform that adjusts automatically as the boom extends or retracts. But when the self-leveling function fails intermittently—requiring repeated bleeding of the hydraulic circuit—it points to a deeper issue within the closed-loop system. This article explores the causes of recurring air intrusion, the role of cylinder seals and counterbalance valves, and how a dual-cylinder repack ultimately resolved the problem.
Symptoms and Observations

• Self-leveling works after bleeding the system, but fails again within a week.
  
• Manual platform leveling functions correctly.
  
• Bleeding involves cycling the platform level function with the boom fully extended.
  
• Bleeding is performed using auxiliary power, not the engine.
  
• Cleaning and resealing counterbalance valves (CBVs) did not resolve the issue.
  

• Master Cylinder: Initiates movement based on boom extension.
  
• Slave Cylinder: Mirrors the master’s movement to level the platform.
  
• Counterbalance Valves (CBVs): Prevent uncontrolled movement and hold pressure.
  
• Hydraulic Lines: Connect master and slave cylinders in a closed loop.
  

• Worn Cylinder Packing: Seals inside the master or slave cylinder may degrade, allowing air to enter during retraction or extension.
  
• Damaged Piston Rods: Scoring or corrosion can compromise seal integrity.
  
• Loose Fittings or Cracked Lines: Even minor leaks can introduce air over time.
  
• Faulty CBVs: If valves fail to hold pressure, fluid may cavitate, drawing in air.
  

• Raise the boom until the lift cylinder deadheads.
  
• Cycle the platform level function fully up and down twice.
  
• Perform all steps using auxiliary power.
  

• Removing each cylinder from the boom assembly.
  
• Disassembling and inspecting internal seals and packing.
  
• Replacing worn components with OEM seal kits.
  
• Reinstalling and testing under full extension.
  

• Inspect cylinder seals every 1,000 hours or annually.
  
• Replace CBVs if pressure holding becomes inconsistent.
  
• Use engine power for bleeding when possible to ensure full hydraulic flow.
  
• Monitor platform angle sensors for drift or calibration errors.
  
• Keep a log of self-leveling performance to detect early signs of failure.
