Part of the John Deere Repair Manuals.
This 250-page John Deere 4400 Technical Manual (OEM #TM4541) covers the complete transmission, axle, hydraulic, and electrical service procedures for the 4400 and 4500 Telescopic Handlers. Inside, you get full functional schematics with part and section designations, a dedicated wiring section covering fuses, relays, and battery troubleshooting, and hydraulic pump and priority valve fault-finding charts that walk you through the boom, steering, and cylinder circuits step by step. The differential support to axle casing bolts torque to 169 N-m (124.5 lb-ft), and the crown wheel bearing locking plate calls for just 13 N-m; these are the numbers you won't find guessing on a forum. No more chasing an electrical fault with a test light and hope. Every section is bookmarked, so you jump straight from the disassembly procedure to the torque table without flipping through 250 pages by hand. Pull it up on your phone next to the boom and get the axles, brakes, and hydraulics back to spec on the first try.
