The Importance of Serial Numbers in Equipment Management
Serial numbers are more than just identification—they’re the key to accurate parts ordering, service history tracking, warranty validation, and resale documentation. For motor graders like the John Deere 570 series, locating the correct serial number can be the difference between a smooth repair and a costly delay. These numbers are tied to production batches, component revisions, and even emissions compliance, especially in Tier-regulated markets.
John Deere, founded in 1837, has produced thousands of motor graders under the 570 designation, including the 570A, B, and later G and H variants. Each model carries unique serial number placements and formatting, which can vary slightly depending on year and factory origin.
Standard Serial Number Locations on the 570 Series
Traditionally, the serial number plate on a John Deere 570 motor grader is mounted in one of the following locations:

• On the frame rail near the left rear tire
  
• On the right side of the engine block or bell housing
  
• Inside the operator’s cab near the control console
  
• On the articulation joint or pivot frame
  
• On the transmission housing near the dipstick
  

• Frame rail: The main longitudinal structural member of the grader chassis.
  
• Articulation joint: The pivot point allowing the front and rear halves of the grader to steer independently.
  
• Bell housing: The casing that surrounds the flywheel and connects the engine to the transmission.
  

• Check stamped numbers on the engine block, which often include partial serial identifiers
  
• Inspect hydraulic pump housings and valve bodies for casting codes linked to production runs
  
• Use the transmission casting number and compare it with John Deere service bulletins
  
• Look for etched or stamped numbers on the rear differential housing
  
• Reference the original purchase invoice or dealer delivery documents
  
• Contact John Deere with component serials (engine, transmission, axle) to triangulate the machine’s build date
  

• JDLink telematics systems may store serial data if previously activated
  
• Dealer service records often include serial numbers tied to past repairs
  
• Parts ordering systems can reverse-search by component serials
  
• Some dealers offer mobile scanning tools to detect etched codes under paint layers
  

• Photograph and document serial plates during initial purchase or inspection
  
• Record engine, transmission, and axle serials separately for redundancy
  
• Avoid painting over serial plates—mask them during refinishing
  
• Keep a laminated copy of serial data in the cab for quick reference
  
• Use a permanent marker or etching tool to record serials in hidden locations as backup
  
• Collaborate with dealers to register machines in service databases

What Is the Engine Brake and How Does It Work?
An engine brake, also known as an exhaust brake, is a system designed to slow down a vehicle by using the engine’s compression to generate braking force. When activated, the engine brake redirects the engine's exhaust gases, creating backpressure that helps to reduce the vehicle's speed without using traditional friction brakes.

• Compression Braking: The engine brake works by utilizing the engine’s compression stroke to slow the vehicle. It temporarily restricts the exhaust valves, causing the engine to act as a pump that resists the turning of the crankshaft.
  
• Exhaust Brake: In addition to compression braking, the exhaust brake creates additional resistance by diverting exhaust gases back into the engine’s intake. This method of braking reduces wear on the conventional braking system by supplementing it with engine-driven braking power.
  

1. Reduced Brake Wear: The engine brake helps reduce wear on traditional friction brakes, extending their lifespan and lowering maintenance costs over time.
   
2. Enhanced Safety: In heavy-duty applications, especially when descending long grades, the engine brake provides additional braking power. This increases the overall safety of the vehicle by preventing brake fade, a condition where traditional brakes lose effectiveness due to overheating.
   
3. Improved Control: The engine brake allows drivers to maintain better control of the vehicle, especially when navigating steep slopes. It can help maintain a steady speed without constantly applying the foot brake, which reduces driver fatigue.
   
4. Fuel Efficiency: By relying on engine braking, drivers use less fuel compared to constantly applying the traditional braking system. This can result in better overall fuel efficiency during long, heavy-load trips.
   

1. Loss of Braking Power
   One of the most noticeable signs that something is wrong with the engine brake is a sudden loss of braking power. When this happens, the vehicle may not slow down as expected when the engine brake is engaged. This could be caused by a variety of issues, including malfunctioning components or low fluid levels.
   Possible Causes:
   • Faulty exhaust valve or actuator
     
   • Blocked exhaust system
     
   • Leaks in the system that reduce backpressure
     
   • Low or dirty brake fluid
     
   • Electrical issues affecting the activation of the engine brake
     
   Solution: The first step in addressing a loss of braking power is to inspect the exhaust system for blockages and leaks. Check the actuator and exhaust valve to ensure they are operating properly. If needed, flush or replace brake fluid and address any electrical faults.
   
2. Noisy Operation
   Another common issue is unusual noise when the engine brake is engaged. This can be a loud, grinding, or rattling noise that is typically caused by worn or damaged components within the engine brake system.
   Possible Causes:
   • Worn exhaust brake valve
     
   • Faulty or worn compressor components
     
   • Dirty or damaged brake actuator
     
   Solution: Inspect the engine brake system, paying particular attention to the exhaust valve, compressor, and actuator components. Clean or replace any parts that are worn or damaged.
   
3. Intermittent Functionality
   If the engine brake intermittently engages or fails to engage altogether, it can be due to electrical issues or sensor malfunctions. These sensors are responsible for detecting when the engine brake should be activated based on driving conditions.
   Possible Causes:
   • Faulty sensors or wiring
     
   • Electrical system issues
     
   • Failed actuator relay
     
   Solution: Check the electrical system for any loose or damaged wires. Replace any faulty sensors or relays to ensure that the system works as intended.
   
4. Overheating
   While the engine brake system is designed to enhance braking efficiency, it can overheat if it is used excessively or if the exhaust system is not functioning correctly. Overheating can cause the engine brake to become less effective, and may even result in permanent damage to the system.
   Possible Causes:
   • Prolonged use without sufficient cooling
     
   • Blockages or restrictions in the exhaust system
     
   • Overuse of the engine brake without adequate intervals for cooling down
     
   Solution: Ensure that the exhaust system is clear and free from restrictions. Avoid excessive use of the engine brake, and allow adequate time for the system to cool down between uses.
   

1. Regular Inspections
   Conduct regular inspections of the engine brake system to check for wear and tear. Pay close attention to the exhaust valves, actuators, and compressor. Any damaged or worn components should be replaced promptly to prevent more severe issues down the line.
   
2. Clean the Exhaust System
   The exhaust system plays a key role in the engine brake’s performance. Ensure that the exhaust system is free from debris, blockages, and excessive carbon buildup. This will allow the engine brake to work efficiently and prevent unnecessary strain on the system.
   
3. Monitor Brake Fluid Levels
   The hydraulic brake system is essential for the engine brake to function properly. Regularly check the brake fluid levels and ensure that the fluid is clean. Low or dirty brake fluid can cause the engine brake to lose effectiveness.
   
4. Test the System Periodically
   It’s important to periodically test the engine brake system to ensure that it is functioning correctly. During routine maintenance, engage the engine brake and listen for any unusual noises or performance issues. If any problems are detected, address them immediately.
