Part of the John Deere Repair Manuals.
TM-1199 covers the John Deere 8440 and 8640 four-wheel-drive tractors. The Repair sections and the Operation and Tests sections are in one volume.
This book gives the factory figures, from the 8640 cylinder head cap screw torque to the rockshaft surge relief opening pressure. It also has the tractor wiring diagram and the hydraulic circuit diagrams.
Repair runs from Section 10 to Section 95, and Operation and Tests from 220 to 290.
