Part of the Case IH Repair Manuals.
Strip, test and put back together the Case IH Farmlift 633, 636, 737, 742 and 935 Stage IV telehandlers with factory service manual 51546954, dated 28/11/2018. It covers the NEF 4 Tier 4B engine, the powershift transmission, both axles, brakes, boom hydraulics, steering, the cab and the SCR/AdBlue aftertreatment.
Every day a telehandler sits with an amber light or a derated engine is a day of pallets and bales not moved. The fault code procedures for the ECU, TCU, UCM and ADIC, the relief pressures and the capacities are what get it back on the yard.
Print the sections you need and take them to the bench. They can get oily there, and the book on the shelf stays clean.
