Truck air-conditioning and cab climate: common HVAC faults

When truck air conditioning is not cooling properly, the cause can sit in the airflow side, refrigerant circuit, compressor drive or electronic controls. Weak airflow may point to a restricted cabin filter or blower problem, while warm air has several possible causes. Confirm the symptom and separate airflow, temperature-control and refrigerant-related faults before replacing parts.

A cab that blows warm air, has weak vent airflow or will not demist consistently does not immediately identify the failed component. Similar complaints can come from different parts of the HVAC system, so diagnosis should start with …

Power take-off (PTO) systems in vocational trucks

Vocational truck operating body equipment on a work site

A power take-off, or PTO, is a mechanical drive that transfers power from a truck’s transmission, engine or driveline to auxiliary equipment such as a tipper hoist, agitator, crane or vacuum pump. In many vocational trucks, a transmission-mounted PTO drives a hydraulic pump, although the arrangement depends on the transmission, equipment and intended duty.

When body equipment will not operate, the fault may sit in the PTO, its controls, the connection to the driven equipment or the …

Filtration in harsh Australian environments: protecting engines and components on construction sites

Tipper truck operating on a dusty construction site

Dust, water and contaminated fluids can cause wear long before a truck shows an obvious problem. On construction sites, contamination can reach a truck through the air intake, fuel supply, hydraulic systems and during servicing.

For tippers, agitators and other vocational trucks, effective filtration depends on using the correct filter, inspecting the surrounding system and considering the conditions the vehicle works in.
Why does filtration matter on construction sites?
Construction trucks can spend significant time on …

Sitrak truck maintenance: common wear points and how to maximise uptime

Mechanic inspecting a heavy truck from underneath in a workshop

Heavy-duty Sitrak trucks used in civil, quarry and construction work can spend their days carrying high loads, operating over rough surfaces and repeating short load, haul and tip cycles. Those conditions can place significant demands on the systems that keep the truck moving.

For workshops, effective Sitrak truck maintenance starts with knowing exactly which vehicle is being serviced. The Australian C7H and G7S ranges may cover similar heavy-duty prime mover and tipper applications, but they belong to different emissions generations …

Sitrak truck models in Australia: Which model suits which application?

The Sitrak range covers very different types of work, from urban rigid freight and concrete agitators to heavy tipper applications, linehaul, B-double and road train operations. The most useful way to compare the models is therefore by application first, then by emission standard and configuration.

The supplied Australian range data separates common models into Euro 5 and Euro 6 generations. Within those generations, the C-series models sit towards heavier prime mover and vocational work, while the G5 platforms cover rigid cargo, agitator and selected tipper configurations. Exact suitability still depends on the completed vehicle, body, axle loads …

Truck Steering and Suspension Wear: What Workshops Should Watch For

A construction truck does not need a major steering or suspension failure before something starts to feel wrong.

The steering may become less precise. A knock may develop over rough ground. One steer tyre may begin wearing differently from the other. Ride height can change, or a truck that once settled quickly after a bump may start moving around more than usual.

For trucks working between sealed roads, quarries and …

What It Takes To Support Truck And Dog Combinations On Australian Job Sites

Truck and dog combinations are a staple of day-to-day operations across Australia’s civil and construction sector. From tasks like hauling aggregates out of quarries through to moving material across sites with large, complex infrastructure setups, these are vehicles that are designed for capacity, flexibility, and endurance. Operating in some of Australia’s toughest environments means they also need a highly considered approach to maintenance, parts supply, and workshop support. When these foundations are in place, truck and dog combinations can be supported to deliver their best work in high-pressure environments day in and day out. In many operations, …

Keeping Tippers and Agitator Trucks Moving in Harsh Australian Construction Conditions

Tipper and agitator trucks are critical players in Australia’s civil and construction sector, playing an essential role in moving bulk materials and delivering concrete across job sites. These vehicles are designed in every aspect to perform under pressure, whether that’s hauling heavy loads or completing large-scale infrastructure pours. In Australia’s demanding conditions, where heavy loads, rough terrains, and constant use are the norm, keeping them operational and ready to deliver each day requires a proactive and strategic approach. In many cases, these trucks are …

Integrating Hino Trucks Into Modern Fleet Management And Telematics Systems

Like many industries across Australia, fleet operations are becoming increasingly data-driven. As a result, the ability to integrate vehicles into telematics and fleet management systems is no longer optional. It is now a critical requirement for gaining visibility, improving operational efficiency, and enabling proactive maintenance strategies that reduce risk and cost.

Hino has recognised this shift and has developed its trucks to align with modern, data-led operating environments. Integration with telematics platforms is designed to be straightforward, allowing fleet managers to access meaningful insights without unnecessary complexity. This approach ensures that Hino vehicles are not only reliable …

What Australian Operators Should Know About Hino Drivetrain And Powertrain Performance

Keeping trucks operating efficiently across Australia’s demanding conditions requires a clear understanding of drivetrain and powertrain performance. For fleet managers and operators running Hino trucks, understanding how these systems function, and what can be expected from them, has a direct impact on fuel consumption, reliability, and long-term maintenance costs. This overview provides a practical reference for Australian operators looking to better understand Hino drivetrain and powertrain performance.
