ISXe5 in the groove at Nolan’s

Posted: April 3, 2013 in Heavy Duty Trucks

Cummins looks set for a greater presence in the Nolan’s Interstate Transport fleet with the release of the ISXe5 engine.

Nolan’s has been part of Cummins’ official field test program for the ISXe5, operating two Kenworths with the new 15-litre engine that uses SCR technology for emissions reduction.

One test engine is in a K200 rated at 600 hp/1850 lb ft, while the other is in a T409SAR rated at 550 hp/1850 lb ft.

“Our preference for our fleet now is SCR and we have the storage infrastructure in place to handle the requirement for AdBlue (urea),” says Nolan’s director Adrian (‘Flea’) Nolan.

Nolan’s has a 10,000-litre AdBlue tank capacity in Melbourne and 15,000-litre capacity at its headquarters at Gatton, 90 km west of Brisbane.

The T409SAR is equipped with a 220-litre AdBlue tank and a diesel capacity of 1420 litres, while the K200 also carries 220 litres of AdBlue but has a higher diesel capacity of 1500 litres.

A highly successful family company, Nolan’s specialises in refrigerated transport, operating over 130 trucks and 200 trailers. The linehaul segment of the fleet comprises 75 prime movers on single trailer, B-double and roadtrain operations.

The company’s base at Gatton is in the Lockyer Valley, a region that encompasses some of the richest farming land in Australia from where Nolan’s hauls produce to markets and supermarkets in Brisbane, Sydney, Melbourne and Adelaide.

As a national carrier, Nolan’s also services customers from much further afield than the Lockyer Valley as a vital link in the supply chain.

Nolan’s first Cummins ISXe5 went into service in June 2012, and the second followed several months later. The highest-kilometre unit, in the K200, had done over 130,000 km at the beginning of February while the other had clocked just over 100,000 km.

“We’ve had no issues…both engines are proving very reliable,” says Flea Nolan. “Apart from a couple of software changes as part of the field test program, the engines basically haven’t been touched.”

He says the fuel economy of the ISXe5 is a “big bonus” compared with the consumption of the EGR engines in the fleet.

Pulling a single trailer, the T409SAR is averaging 2.1 km/litre, while the K200 on B-doubles – it is also doing some roadtrain doubles work – is running at 1.78 km/litre (figures don’t include AdBlue consumption).

The K200 is fitted with Eaton’s automated UltraShift transmission which Nolan says is very well matched to the ISXe5. Cummins has, in fact, worked closely with Eaton on development of the shift software for this transmission.

As part of the field test program, Nolan’s oil drain intervals for the ISXe5 are 40,000 km compared with 20,000 km for the EGR engines. “The field test requirement is that we carry out oil sampling every week and 40,000 km is looking good,” says Flea Nolan.

Cummins’ guidelines for the ISXe5 stipulate the use of CI-4 specification oil for the 40,000 km drain intervals, while the use of CJ-4 oil reduces the drain intervals to 32,000 km.

Preventive maintenance is a key focus at Nolan’s because of the sensitivity of the freight. “This is a select game (refrigerated transport) and our maintenance has to be spot on,” says Flea Nolan.

The company recently installed a roller brake tester/shaker at its Gatton workshop facility and all trucks are put over it at scheduled service to meet NHVAS (National Heavy Vehicle Accreditation Scheme/TruckSafe standards.

Nolan’s employs 28 mechanics as well as four refrigeration technicians, three boiler makers and an apprentice who looks after panel repairs.

With Cummins’ service support heavily influencing Nolan’s, the company has had over 100 ISX/Signature engines since 1999.

While Cummins’ presence in the fleet has reduced in recent times, the performance of the two ISXe5 field test engines certainly looks set to influence future truck purchases.

Ron Runge, who has piloted trucks for Nolan’s for 30 years and has been driving one of the field test engines since new, doesn’t hesitate to describe the ISXe5 as the “engine of the future”.
