Terex TA40 and the Detroit Series 60 Powertrain
The Terex TA40 articulated dump truck was engineered for heavy-duty earthmoving and mining operations, boasting a payload capacity of 38 metric tons and a robust drivetrain built to endure punishing terrain. Terex, originally founded in 1933 and later acquired by various conglomerates including General Motors and Ingersoll Rand, developed the TA40 as part of its push into high-capacity off-road haulage. The truck is powered by the Detroit Diesel Series 60 engine—a 12.7-liter inline-six turbocharged diesel known for its electronic control and fuel efficiency.
The Series 60, introduced in 1987, was one of the first heavy-duty engines to feature full electronic management via the DDEC (Detroit Diesel Electronic Control) system. It became a staple in both on-highway and off-highway applications, with over 1 million units sold globally by the early 2000s.
Crank No Start Symptoms and Initial Checks
A common issue with the TA40 is a crank-no-start condition. The engine turns over normally but fails to fire. In one case, the truck would run briefly on ether, confirming that compression and mechanical timing were intact. However, the check engine light remained illuminated, and diagnostic blink codes could not be activated—likely due to the engine entering protection mode.
Initial diagnostics included: - Verifying fuse and relay integrity
- Confirming fuel availability and primer pump function
- Replacing a broken fuel pressure sender
- Testing the fuel return check valve at the cylinder head
- Bleeding fuel manually from the head
Despite these steps, the engine refused to start, suggesting a deeper issue within the electronic fuel delivery system.
Terminology Notes- DDEC: Detroit Diesel Electronic Control, the onboard computer system managing fuel injection, timing, and diagnostics.
- Fuel Pressure Sender: A sensor that reports fuel pressure to the ECU; failure can trigger protection mode.
- Check Valve: Prevents backflow in the fuel return line, maintaining pressure at the injectors.
- CAN Bus: Controller Area Network, a communication protocol linking electronic modules.
Electronic Protection Mode and Diagnostic Limitations
When the Series 60 enters engine protection mode, it disables certain functions to prevent damage. This includes diagnostic blink code activation and, in severe cases, fuel injection. The inability to retrieve fault codes complicates troubleshooting, especially in field conditions without access to a laptop or diagnostic interface.
Voltage tests on the throttle position sensor (TPS) and CAN high/low lines showed normal readings, ruling out communication failure. However, the ECU may still suppress fuel delivery if it detects critical faults—such as low fuel pressure or sensor mismatch.
Fuel Transfer Pump and Pressure Thresholds
The Series 60 requires minimal fuel pressure to initiate injection—typically around 20 psi during cranking. If the transfer pump is weak or the pressure sender misreports, the ECU may block injection. Testing fuel pressure while cranking is essential. A technician in Alberta noted that a failing transfer pump produced only 8 psi, insufficient to trigger injection. Replacing the pump restored normal starting behavior.
Field Anecdote and Practical Insight
In Queensland, a mining operator faced a similar issue with a TA40. After replacing the fuel pressure sender and bleeding the system, the truck still wouldn’t start. A visiting technician discovered that the ECU had logged a low voltage fault during cranking. The battery, though appearing charged, dropped below 10 volts under load. Installing a new battery resolved the issue. The operator later added a voltage monitor to the dash to prevent recurrence.
Recommendations for Troubleshooting TA40 No Start- Test fuel pressure during cranking with a mechanical gauge
- Verify battery voltage remains above 11 volts under load
- Replace fuel pressure sender with OEM-grade component
- Inspect wiring harness for abrasion or corrosion near the ECU
- Attempt to clear engine protection mode via diagnostic software
- Check for air intrusion in fuel lines and fittings
Preventive Measures and Long-Term Solutions- Install a fuel pressure gauge in-cab for real-time monitoring
- Use dielectric grease on sensor connectors to prevent moisture ingress
- Replace fuel filters every 250 hours or as per service schedule
- Maintain battery health with load testing every quarter
- Keep a spare pressure sender and relay kit onboard for remote sites
Conclusion
The Terex TA40, powered by the Detroit Series 60, is a formidable machine—but its reliance on electronic diagnostics and fuel pressure thresholds can complicate field repairs. A crank-no-start condition often stems from sensor faults, low voltage, or fuel delivery issues. By combining mechanical checks with electronic awareness, operators can restore function and avoid costly downtime. In remote operations, preparation and understanding of the Series 60’s behavior are as critical as the tools themselves.

Case 580D and the Lucas CAV Injection System
The Case 580D backhoe loader, produced in the early 1980s, was part of Case’s highly successful 580 series. Known for its mechanical simplicity and rugged design, the 580D featured a naturally aspirated diesel engine paired with a Lucas CAV rotary injection pump. This pump, widely used in European and North American agricultural and construction equipment, operates on a mechanical principle using a rotating distributor and cam ring to deliver fuel to each injector.
While the 580D remains a reliable workhorse, its age and mechanical fuel system mean that issues like hard starting or fuel leaks are not uncommon. One recurring problem is a crank-no-start condition, often linked to fuel delivery faults within the injection system.
Symptoms and Initial Observations
A typical crank-no-start scenario involves the engine turning over normally but failing to fire. In this case, the operator noted: - Diesel dribbling from loosened injector lines, but not the strong spray expected
- White smoke puffing from the exhaust during cranking
- No improvement with starter fluid
- A history of fuel leakage from the injection pump’s O-ring, which had recently stopped
These signs suggest insufficient fuel pressure reaching the injectors, possibly due to a failed fuel shut-off solenoid or internal pump wear.
Terminology Notes- Lucas CAV Pump: A rotary-type mechanical fuel injection pump used in older diesel engines.
- Fuel Shut-Off Solenoid: An electrically actuated valve that controls fuel flow into the injection pump.
- White Smoke: Typically indicates unburned fuel due to low compression, poor timing, or weak injection.
- Emergency Cut-Off: A manual lever or flap that shuts off fuel or air to prevent runaway or allow safe shutdown.
Diagnosing the Fuel Solenoid
The fuel solenoid receives 12 volts when the key is turned, allowing fuel to flow into the pump. A clicking sound may indicate activation, but it doesn’t guarantee proper function. Voltage drop during cranking can prevent full engagement. To test:- Use a multimeter to verify voltage remains stable during cranking
- Bypass the solenoid by removing the plunger and spring (on older models)
- Hold the solenoid open manually with a wire or jumper
In one case, manually actuating the emergency cut-off flap restored fuel flow and allowed the engine to start, confirming that the solenoid or internal linkage was the culprit.
Pump Rebuild Considerations
If the pump has been leaking for years and now fails to deliver fuel, a rebuild is likely necessary. A master rebuilder can replace worn seals, inspect the cam ring, and recalibrate the distributor head. Shipping the pump to a specialist is often more cost-effective than sourcing a new unit, especially for legacy equipment.
Operators should consider:- Replacing all seals and gaskets
- Inspecting the governor linkage and shut-off mechanism
- Bench testing the pump before reinstallation
- Using priority mail or air freight to minimize downtime
Alternative Diagnostic Strategies
A mechanic from Russia suggested isolating leaking injectors by disabling one at a time. This involves:- Loosening the high-pressure line to each injector
- Placing a steel ball in the fitting to block fuel flow
- Retightening and attempting to start
This method can identify a faulty injector that’s bleeding off pressure, though it’s more applicable to common rail systems than rotary pumps.
Anecdote from the Field
In Hawaii, a contractor had lived with a leaking pump for years, using a ball valve to stop fuel drip when parked. When the leak stopped and the engine refused to start, he suspected the shut-off solenoid had failed. After manually resetting the emergency cut-off, the engine fired up. He later contacted a pump rebuilder in South Carolina, who had trained with a fuel shop owner on the Big Island decades earlier—a reminder of how small the diesel repair world can be.
Recommendations for Case 580D Owners- Monitor fuel leaks and address them early—drips often precede failure
- Test solenoid voltage during cranking, not just at rest
- Keep a manual override method for emergency cut-off
- Consider a full pump rebuild if leaks and starting issues coincide
- Use OEM-grade filters and prime the system thoroughly after service
Conclusion
Crank-no-start conditions in older diesel equipment like the Case 580D often trace back to fuel delivery faults. The Lucas CAV pump, while durable, requires clean fuel, stable voltage, and intact seals to function properly. By combining electrical testing, manual overrides, and professional rebuilds, operators can restore reliability and extend the life of their machines. In a world of electronic diagnostics, sometimes the solution is still mechanical.

The Role of Pin Presses in Undercarriage Maintenance
Excavator track pins are critical components that link the track chain together, allowing the machine to move across terrain. Over time, these pins wear out or seize, requiring removal and replacement. A pin press is a hydraulic tool designed to push these pins out of the track links with controlled force, minimizing damage and operator fatigue. While essential for large machines, their use in mid-size excavators—especially those under 25 tons—remains a topic of debate among mechanics and contractors.
Terminology Notes - Track Pin: A cylindrical steel rod that connects track links in an excavator’s undercarriage.
- Master Pin: A removable pin used to split the track chain for maintenance.
- Pin Press: A hydraulic or mechanical device used to remove or install track pins.
- Drift: A steel punch used manually to drive out pins with a hammer.

Shop-based presses, while more powerful and stable, require transporting the machine or track chain to a facility.
One mechanic in Victoria received a quote of AUD $6,500 for a portable press—excluding the hydraulic pump. He had previously paid AUD $1,200 for a technician to travel and perform the job, highlighting the scarcity of local service providers. The high cost and limited availability push many operators to consider alternatives.
Manual Methods and Veteran Wisdom
Experienced mechanics often favor manual removal using sledges and drifts. A 28-pound hammer, combined with a custom drift holder, can remove pins effectively on machines up to 25 tons. Heating the link opposite the pin with a torch softens the metal, reducing resistance. Some operators even use liquid nitrogen to shrink pins before removal, though this method raises safety concerns.
A retired service manager in Scotland shared that he avoided presses for machines under 40 tons, preferring a big hammer and torch. He emphasized that while presses are precise, they rarely save time in field conditions. His approach was echoed by younger mechanics who learned from veterans and found manual methods faster and more adaptable.
Designing a Safer Drift Holder
One recurring suggestion is the creation of a robust drift holder that clamps to the track pad. This device would stabilize the drift, reduce operator fatigue, and improve safety by minimizing flying debris. A curved handle welded to the drift allows one person to hold it while another swings the hammer. Though simple, this innovation can transform a two-person job into a more efficient and safer process.
Commercial Press Options and Global Suppliers
While some Australian contractors prefer local suppliers, others explore international options. Companies in the U.S. and Europe offer track presses ranging from 50 to 100 tons of force. Brands like WTC Machinery and HEMS Ltd provide both shop and portable models, though shipping and support can be challenging. Italian manufacturers like Big Nozzi are praised for quality but may be difficult to source in remote regions.
Cost-Benefit Analysis and Usage Frequency
The decision to buy a pin press depends heavily on usage frequency. For contractors who split chains monthly, the investment may be justified. For occasional jobs, manual methods are more economical. One operator calculated that the cost of hiring a technician for six jobs matched the price of a press, prompting him to consider purchasing. However, others argue that the time and effort to set up the press often outweigh its benefits.
Anecdote from the Field
In Ontario, a farmer and excavating contractor shared a story of removing a pin from his 240 excavator. It took three people: one on the hammer, one holding the drift, and one heating the link. The mechanic took a sledge handle to the ribs during the process, prompting laughter and a vow to build a better drift holder. Despite the struggle, the job was completed without a press, reinforcing the value of teamwork and improvisation.
Recommendations for Mid-Size Excavator Pin Removal- Use a 28 lb sledge and a curved-handle drift for manual removal
- Heat the opposite link with a torch to ease pin movement
- Consider building a clamp-on drift holder for safety and efficiency
- Reserve portable presses for machines over 30 tons or high-volume operations
- Apply dielectric grease to connectors if using hydraulic tools in wet conditions
Conclusion
In Australia and beyond, the debate over excavator pin presses reflects a broader tension between tradition and technology. While hydraulic presses offer precision, their cost, weight, and setup time make them impractical for many field jobs. Veteran mechanics continue to rely on sledgehammers, torches, and ingenuity—proving that sometimes, the old ways still work best. For contractors weighing the investment, the key is frequency, safety, and the willingness to swing a hammer when needed.
