Part of the New Holland Operator Manuals.
The Diesel Exhaust Fluid supply module filter hides behind a cover with its own torque value, and guessing there is how a fresh tank of AdBlue ends up on the shop floor. From the SCR system it widens out: rear PTO, three-point hitch, remote hydraulics, front axle service, and the full maintenance chart.
Coverage is the T8.320, T8.350, T8.380, T8.410 and T8.435, plus the T8.380, T8.410 and T8.435 SmartTrax, serial prefix ZHRE94001 and above, New Holland publication 48159318. It runs 728 pages as a PDF download you read on the laptop in the shop or print by the section.
One wrong part or a second teardown costs more than the book. Buy it once and it stays yours for this tractor, which matters when the weather, not the calendar, decides how long the machine can sit out of the field.
