Across nearly 1,400 pages, this John Deere 1023E 1025R 1026R technical manual gives a technician everything needed to move from symptom to fix: component locations, theory of operation for each major system, step-by-step diagnostic testing, adjustment specifications, and full teardown/rebuild procedures for the engine, power train, hydraulics, steering, brakes, and electrical system.

Machine Coverage

The manual documents all three EEC variants side by side: the 1023E with its Yanmar 3TNM74 diesel engine, the 1025R with the Yanmar 3TNV80, and the 1026R EEC with the Yanmar 3TNV76 — each an in-line 3-cylinder, liquid-cooled diesel with indirect injection and a mechanical rotary injection pump. It covers the hydrostatic transmission and 2-range gear final drive, fully independent 540 rpm PTO, hydrostatic power steering, internal wet-disk brakes, and the open-center gear-pump hydraulic system shared across the model line, along with fluid capacities, torque specifications, and metric and inch fastener torque charts used throughout every repair procedure in the book.
