Part of the John Deere Repair Manuals.
This is CTM385, the John Deere component technical manual for the Level 14 electronic fuel system on the PowerTech Plus 9.0L (6090) diesel. It covers the high-pressure common rail system end to end: theory of operation, component repair and adjustment, diagnostic trouble code procedures, and electronic fuel system tests, plus the special tools, specifications, and torque values you need to do the work right. Because this is a component manual, it applies to the 9.0L engine wherever Deere installed it - 8R and 8030-series tractors, 9000-series and STS/WTS combines, self-propelled windrowers and more. If your machine has the 6090 with electronic common rail, this is the fuel system book the dealer techs use.
