Part of the John Deere Repair Manuals.
All 581 pages of this John Deere AMT600, AMT622, and AMT626 Technical Manual (OEM #TM1363) zero in on your 1991 Material Transporter: power train teardowns, electrical diagnosis, steering and brake service, and full hydraulic procedures. Inside: wiring schematics for the starting and charging systems, plus hydraulic schematics with complete circuit routing for the lift and drive assemblies. You get a dense troubleshooting section with model-specific diagnostic paths for each variant, backed by exploded views and step-by-step rebuild procedures for the transaxle, drive axles, and pulley assemblies. Confirm brake pedal freeplay at 18–22 mm (0.70–0.87 in.); the AMT600 engine rates at 6.3 kW (8.5 hp) versus 7.5 kW (10 hp) on the AMT622/626. Your machine is down. Keyword search and bookmarked sections get you to the right spec without digging through 581 pages cold.
