Part of the John Deere Repair Manuals.
This is the Operation and Tests (Diagnosis) manual for John Deere 6200, 6300, 6400 and 6500 tractors, including the low-profile L versions, built 1994 to 2000. It is the diagnostic half of the factory library: pressure test specs, operational checks and full wiring diagrams for cab and ROPS machines. You get dynamometer and preliminary engine tests, fuel transfer pump checks (15 kPa pressure, 110 litres per hour flow), cooling system pressure testing at 50 to 70 kPa, SyncroPlus and PowrQuad transmission tests, hydraulic pump and SCV diagnostics, hydrostatic steering and brake tests, plus the diagnostic trouble codes and calibration steps for the electronic hitch control units (HCU/RCU). Component teardown lives in the separate Repair manual - this book tells you what is actually wrong first.
