John Deere offers new Tier 4 engine conversion kit
Kit maintains engine reliability, durability and performance in high sulfur markets
Beginning in 2015, the John Deere Construction & Forestry Division will offer a retrofit kit that will enable Interim Tier 4 (IT4) machines to be sold in countries where ultra-low sulfur diesel (ULSD) fuel is not available. The kit can be used on John Deere-powered crawler dozers, wheel loaders, articulated dump trucks, motor graders, excavators, and backhoes.
“This kit will allow customers in markets worldwide to run John Deere IT4 products that deliver premium performance, uptime and durability regardless of fuel sulfur level,” said Andrew Kahler, product marketing manager, engine and driveline, John Deere Construction & Forestry.
The John Deere retrofit kit maintains engine reliability and durability by disabling or removing sulfur sensitive components and systems. It maintains engine performance utilizing software recalibration in addition to minimal hardware updates.
In contrast to other solutions, it is designed for fuel sulfur levels from 15 parts per million to well beyond 5,000 parts per million. ULSD is diesel fuel with 15 parts of sulfur per million or lower.
New John Deere equipment for export to non-ULSD countries will continue to offer lower tiered engines that meet regional emissions standards and will reliably operate with the local available fuel. The kit will be supported by the Worldwide John Deere Dealer Network.
