Part of the John Deere Repair Manuals.
This is the repair side of the John Deere 5R library: one manual covering all six 2008-2014 models - 5080R, 5090R, 5100R and the narrow 5080RN, 5090RN, 5100RN. It walks the full teardown and rebuild of the 4.5L 4045HL284 turbo engine (80, 90 or 100 hp depending on model), the PowrQuad transmission clutch packs, MFWD front axle and final drives, steering, brakes and the hydraulic system with SCVs and rockshaft. What matters is the numbers: assembly torques, valve clearances, rolling drag torque on the differential, hydraulic pressure test values, plus the JD special tool list. If you are splitting one of these tractors or pulling the head, this is the book with the specs.
