Part of the John Deere Repair Manuals.
What a John Deere JD555 crawler loader should measure, from track sag to axle shaft end play, is settled by one book: the John Deere JD555 technical manual PDF, TM-1111, running 687 pages. Section 90 System Testing takes up nearly a fifth of it and works through engine, electrical, hydraulic, power train and winch diagnosis in order, while wiring diagrams trace the charging circuit and harness and hydraulic schematics map oil routing through the backhoe and test circuits. Teardown coverage runs from rollers and idler springs through the torque converter, power shift clutch, engine and winch drive, then on to loader frames, buckets and loader hydraulics. Set track sag at 7/8 to 1-1/8 inch (22 to 29 mm) and hold axle shaft end play to 0.001 to 0.005 inch (0.03 to 0.13 mm). A bearing job stalls on one missing clearance. Buy this bookmarked, text-searchable PDF once and you keep it for the life of your JD555.
