John Deere has long been synonymous with reliability and innovation in engine design, and their 4045 Powertech range of diesel engines are no exception. There is no more reassuring sound than the smooth, distinctive song of a John Deere, whether it’s in the paddock under a tractor bonnet or running industrial machinery. The 4045T2 four-cylinder, vertical water-cooled powerhouse delivers an impressive 127.4 horsepower (93.0 kW) at 2400 RPM. But beyond raw power, the 4045T2 stands out for its cutting-edge engineering and design features and is the powerplant of choice for the Firmus Group, manufacturers of specialist vaccuum tanker semi trailers.
“For an engine of its overall size and horsepower, the John Deere really does have a better power curve,” says Firmus Group Operations Manager Matt Kinlough.
Matt is no stranger to the John Deere 4045 engine range, having serviced them in years gone by as a mechanic. He understands the wide number of applications that this long-proven design delivers.
Firmus Group builds a range of specialist vaccuum tankers for the recovery of all manner of liquids and waste, (including flammable and some dangerous liquids), with a blade vaccuum system.
These are usually semi-trailer mounted setups that can retrieve up to 20,000-plus litres of anything from fuel to mud and rely on a power system that drives both hydraulic tipping and door emptying systems as well as an industrial liquid ring-type industrial vaccuum pump.
This power is where the John Deere 4045T2 variant from Power Equipment steps up to the job.
The John Deere 4045T2 is more than just a high-output diesel engine; it is a testament to intelligent engineering and practical innovation. From its dynamically balanced crankshaft and forged-steel connecting rods to its self-adjusting fan drive and optional engine-balancer shafts, every detail has been meticulously designed to maximize performance, durability, and efficiency.
With a displacement of 4.5 liters and a bore and stroke of 106 x 127 mm, this diesel powerhouse is built for heavy-duty tasks. Its variable speed capability further enhances its adaptability, making it a go-to choice for professionals in agriculture, construction, and industrial sectors.
“The John Deere is effectively the ‘nucleus’ of our system,” explains Matt.
“Power Equipment can provide engine control systems for the John Deere 4045’s, but we designed our own to suit our tankers and their operation.”
“The trailers can be parked independently and must rely on the engine for its full operation – the John Deere’s belt setup drives both the hydraulics and the liquid-ring vaccuum.”
With Firmus Group moving from custom tanker manufacture to a focus on a set range of vaccuum tanker designs, the John Deere 4045T2 “is really the engine that caught our interest and attention for all our needs,” says Matt.
All manner of harsh environments Australia-wide
“As well as meeting power needs, the fact is our equipment gets used all over Australia in all types of conditions and climates,” he said.
“The John Deere isn’t just an easy machine to service and maintain, (including clever features like either-side filter and dipstick options), they’re designed to handle tough conditions and harsh environments so we don’t need to worry about where our equipment may be operated in terms of engine durability.”
At the core of the 4045’s durability is its dynamically balanced crankshaft, which ensures smooth operation under demanding conditions. Formed from nodular iron, the crankshaft offers enhanced toughness, making it ideal for heavy-duty use.
Complementing the robust crankshaft are forged steel connecting rods, a hallmark of superior engine construction. These rods feature a unique 45-degree design that allows for larger crankshaft connecting-rod bearings, enhancing durability and ensuring smooth performance even under high loads.
Heat dissipation is also a crucial factor in engine performance, and John Deere engineers have incorporated replaceable wet-type cylinder liners to address this challenge. These liners are precision-machined for long life and excellent heat dissipation, reducing the likelihood of overheating and contributing to the engine’s overall efficiency.
Whilst John Deere reliability is no new story, neither is the relationship between Firmus Group and Power Equipment.
“Firmus Group have a long-standing relationship with Power Equipment and they have always provided the equipment and expertise we need,” Matt says.
“Of particular note, Steve Harvey and Dean Whitford at Power Equipment have always provided fantastic support and we are grateful for their efforts.”
Like many Australian specialist industrial equipment manufacturers, Firmus Group is not one to rest on successful laurels.
They are in the process of building a new hook-lift skid-mounted vaccuum tank system which can be deployed from a body truck. This new design is also destined to sport the John Deere 4045 engine and Power Equipment is proud to continue powering this ever-successful Australian manufacturer. more!) out of a 28 litre tank.
