The John Deere 4045D and 6068T are proven PowerTech diesel engines powering a wide range of John Deere construction, forestry, and agricultural equipment worldwide. When injectors fail on these engines, you'll experience rough running, misfires, excessive smoke, hard starts, and reduced power output — symptoms that directly impact machine productivity and operating costs. This 4-piece brand-new aftermarket injector set covers part numbers SE500830 and SE500831, fitting the 4045D and 6068T engines across loaders, crawlers, excavators, forklifts, harvesters, bulldozers, dozers, loggers, and bundlers.
