Terex TA35 Dump Truck Overview
The Terex TA35 is a robust off-road articulated dump truck designed for heavy earthmoving and mining operations. Manufactured during the early 2000s, the TA35 was part of Terex’s legacy in producing durable and high-capacity haul trucks. Terex, originally founded in 1933, became known for its construction and mining equipment before its truck division was eventually acquired by Volvo in 2014.
The TA35 features a payload capacity of approximately 35 tons and is powered by a high-torque diesel engine paired with a ZF automatic transmission. This transmission relies on a Transmission Control Unit (TCU), an electronic module that governs gear shifting, torque converter lockup, and diagnostic feedback.
TCU Failure and Common Causes
TCU failures in the TA35 are typically caused by:

• Electrical shorts in the truck’s wiring harness
  
• Voltage spikes during battery charging or jump-starting
  
• Water intrusion due to poor sealing or exposure during maintenance
  
• Internal fuse burnout, which may be repairable if the damage is localized
  

• Inspect and replace internal fuses: Some TCUs include a small internal fuse that can be replaced if the damage is minor. These fuses are often glass-type and require magnification to inspect.
  
• Send the unit for reconditioning: Electronics specialists can often repair TCUs for a fraction of the cost of a new one, especially if only surface components are damaged.
  
• Purchase a compatible unit and reprogram it: A TCU from a similar ZF transmission (e.g., from a Case 621D loader) may be reprogrammed by ZF to match the TA35’s parameters. This option can save up to $1,000.
  
• Order a new unit directly from ZF: ZF maintains a database of transmission configurations and can supply a pre-programmed TCU tailored to the TA35.
  

• Correct firmware matching: The TCU must be programmed with the exact gear ratios, shift points, and torque converter settings for the TA35.
  
• VIN or transmission serial number: ZF uses this data to identify the correct configuration.
  
• Professional installation: Improper wiring or grounding can damage the new unit.
  
• Post-installation diagnostics: A scan tool compatible with ZF systems should be used to verify communication and clear fault codes.

Western Star 4964FX and Detroit Diesel Series 60 Overview
The 1994 Western Star 4964FX is a heavy-duty vocational truck built for long-haul and construction applications. Western Star, founded in 1967, became known for its rugged, customizable trucks tailored to owner-operators and fleet buyers alike. The 4964FX model was often equipped with the Detroit Diesel Series 60 engine, a revolutionary inline-six introduced in 1987 that became the first fully electronically controlled heavy-duty diesel engine in North America.
The Series 60 engine, particularly the DDEC III and DDEC IV variants, featured electronic fuel injection, onboard diagnostics, and a programmable ECM (Engine Control Module). These innovations improved fuel economy and emissions compliance but introduced new layers of complexity in troubleshooting.
Symptoms of a No-Start Condition
In one case involving a 1994 Western Star 4964FX, the truck would crank but not fire. The fuel system had already been bled and verified, eliminating air intrusion or fuel starvation as the cause. This pointed toward an electrical or ECM-related issue.
Key symptoms included:

• Engine cranks normally but does not start
  
• Fuel pump operational and system primed
  
• No check engine light (CEL) illumination with key on
  

• Blown ignition fuse: Often located in the battery box or under the dash
  
• Disconnected or corroded ECM power leads: Especially common in older trucks with exposed wiring
  
• Loose or damaged harness connectors: Particularly the ECM-to-battery harness
  
• Failed ignition relay: Prevents ECM from receiving switched power
  

• Check for CEL illumination with key on
  
• Use a multimeter to verify voltage at the ECM power pins
  
• Inspect all fuses related to ignition and ECM circuits
  
• Confirm ground integrity at the ECM and battery terminals
  
• Use a diagnostic reader compatible with DDEC III or IV to check for stored fault codes
  

• Power and ground
  
• Sensor inputs (e.g., coolant temp, oil pressure)
  
• Actuator outputs (e.g., injectors, Jake brake)
  

Understanding Moly Grease and Its Applications
Molybdenum disulfide (commonly called moly) is a solid lubricant additive used in greases to reduce friction and wear under extreme pressure. A 5% moly content is considered ideal for high-load, low-speed applications such as loader pins, backhoe bushings, fifth wheels, and heavy construction joints. The moly particles embed into metal surfaces, forming a protective film that resists metal-to-metal contact even when the grease is displaced.
Republic Oil’s 5% Moly #1 grease is a lithium complex formulation with a National Lubricating Grease Institute (NLGI) consistency grade of #1. This grade is softer and more pumpable than the more common NLGI #2, making it suitable for cold climates or centralized lubrication systems. However, it may not be ideal for high-temperature or high-speed bearing applications.
Product Characteristics and Packaging Observations
This grease is repackaged from bulk Shell-manufactured drums into generic white tubes or pails. While the product itself is high quality, the packaging lacks branding or protective caps, which may concern users accustomed to sealed commercial tubes. Despite minor shipping damage like flat spots on tube ends, the grease arrives well-packed and ready for use.
Key specifications include:

• Lithium complex thickener
  
• 5% molybdenum disulfide content
  
• NLGI #1 consistency
  
• Drop point of 464°F (240°C)
  
• Gray-black color typical of moly greases
  

Symptom Description
A 315 excavator owner reports that their Cat engine “flutters” — especially at higher RPMs — like a fine miss. They've already replaced the injectors, but the issue persists once the machine warms up and the hydraulics are used.  The problem impacts performance and is “just annoying” rather than completely disabling the machine.

Common Causes Discussed by Experienced Technicians

1. Fuel System Contamination
   • Dirty fuel or water in the tank can cause erratic engine behavior.
     
   • A clogged inlet screen in the transfer pump or a dirty water separator can starve the engine of clean fuel, leading to misfires or fluttering.
     
   • Sediment in the fuel tank should be drained regularly; one user admitted to only draining it seasonally (“spring and fall”), which may allow buildup.
     
2. Worn Fuel Pump (Governor Section)
   • On older 315 models (e.g., A or B series), wear in the governor portion of the injection pump is a known issue.
     
   • The suggested fix: remove and send the pump to a specialist (“injector shop”) for a rebuild.
     
3. Grounding or Electrical Issues
   • Poor or broken ground connections can cause erratic engine behavior and auto-idle problems in Cat excavators.
     
   • A dirty or improperly seated engine speed (RPM) sensor may result in faulty speed control and contribute to “flutter.”
     
4. Pilot & Hydraulic Load Influence
   • Some operators note the flutter or miss only appears under load or when hydraulics are being used, suggesting a fuel delivery / pump demand issue rather than a pure ignition or injector fault.
     
   • If hydraulic demand increases suddenly, the fuel system must keep up; any delay or drop in fuel flow can cause transient misfires.
     

• Fuel Filter & Water Separator Inspection
  Start with the basics: replace the fuel filter, empty and clean the water separator, and ensure the primary suction screen is clean.
  
• Fuel Tank Drain
  Drain out any water/sediment from the fuel tank. This is vital, especially for machines that sit or run in dusty, wet environments.
  
• Inspect the Fuel Pump
  Remove the injection pump and check the governor section for internal wear — this may require sending it to a specialist.
  
• Check Grounds & Wiring
  Verify engine ground wiring — poor ground can lead to unpredictable control issues.
  
• Engine Speed Sensor
  Clean or reseat the RPM sensor. Check its clearance and signal to controller; poor signal may destabilize engine speed under load.
  

• Rebuild or replace the injection pump if wear is confirmed.
  
• Improve fuel system filtration or install a finer secondary filter to catch contaminants.
  
• Repair or reinforce ground wiring, especially around engine and control modules.
  
• Replace or clean the RPM sensor to restore stable engine speed.
  
• Set up a more frequent maintenance schedule for draining the tank and cleaning fuel components.
  

Champion Motor Grader Background
Champion motor graders, particularly models like the 730A from the late 1980s, were built for municipal road maintenance and light construction. Known for their mechanical simplicity and robust frames, these graders often featured Cummins diesel engines such as the 6CT-8.3, paired with basic electrical systems. Champion, originally a Canadian manufacturer, was later absorbed into Volvo Construction Equipment, but many of its machines remain in service across North America.
One common feature in these graders is an electric tachometer driven by the alternator’s AC signal—a design that avoids mechanical cables and instead relies on frequency conversion.
How Alternator-Driven Tachometers Work
Electric tachometers on older machines often use the “P” terminal on the alternator to receive a pulsed AC signal. This signal is proportional to the alternator’s rotational speed, which in turn reflects engine RPM. The tachometer converts this frequency into a readable RPM value.
Key components include:

• P terminal: Located furthest from the alternator’s main output stud, it emits a “wild” AC signal.
  
• Tachometer head: Internally calibrated to interpret frequency based on pulley ratios and alternator pole count.
  
• Wiring harness: Typically includes shielded wires to prevent signal degradation.
  

• Inspecting and replacing corroded connectors: A poor connection on the main charging wire reduced voltage from 12V to 12.5V. Replacing the connector improved current flow and stabilized voltage.
  
• Using a fuse for safe testing: A 5-amp automotive fuse was inserted between the suspected tach wire and the alternator terminal to prevent damage during testing.
  
• Charging the battery before testing: Ensured accurate voltage readings and reduced load on the alternator.
  

• Use a digital multimeter to measure voltage directly at the battery and alternator output stud.
  
• Avoid relying solely on dash gauges, which may be inaccurate due to age or poor grounding.
  
• Ensure all charging wires are clean, tight, and using full conductor cross-section.
  

• Two spade connectors in a side opening
  
• Large output stud connected to starter or battery
  
• Cast body with cooling vents near the oil filter
