Cummins recalls Macks with ISL G natural gas engines

| Monday, October 26, 2015

More than 3,000 Mack trucks with Cummins Westport ISL G natural gas-powered engines have been recalled due to an issue with the oil supply line, according to a National Highway Traffic Safety Administration safety recall report.

Exclusive to Mack trucks with the ISL G engine, the turbocharger oil supply line may come into contact with the turbocharger inlet elbow, the OEM clear air intake clamp, or the air fuel control tube, resulting in an oil leak. Oil leaks close to the engine exhaust manifold increase the risk of a fire, according to the report.

Back in June, Cummins Westport received customer reports of the equipment defect and began an investigation that lasted through September. On Friday, Sept. 23, Cummins Westport stopped shipments of the engines. Two days later, shipments of the engine with improvements to the defect began.

Owners of affected Mack tracks will be notified no later than Nov. 30 as the recall is expected to begin Nov. 20. Drivers can call Cummins Westport at 800-343-7357. Cummins Westport’s number for this recall is C1673.
