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.

John Deere 4400, 4500 Common Problems This Manual Covers
John Deere 4400 telescopic handler boom stuck or unable to extend and retract
Check hydraulic pump flow at the return line filter as detailed on page 161. Verify the flow rate reaches exactly 66 l/min. If flow is low, inspect the main relief valve and check the 115 l hydraulic tank for contamination before replacing components.
Manual Section: Hydraulic Pump Testing p. 161Seat pad safety switch fails to activate when operator sits down, completely disabling the hydraulic system
Remove the two front screws retaining the seat cushion to the frame on page 221. Lift off the cushion and cover to access the switch. Test circuit continuity. If defective, replace the switch. Verify the battery maintains its 128 Ah nominal capacity under load.
Manual Section: Operator’S Cab p. 221Front axle overheating combined with incredibly heavy steering or seized steering column during normal operation
Test the steering relief valve pressure using the procedure on page 204. Confirm the gauge reads exactly 17500 kPa. If pressure drops, inspect the priority valve. Check the front axle differential support bolts and torque them to 169 N·m as listed on page 122.
Manual Section: Hydraulic System p. 204Machine movement during engagement test due to weak holding power from the parking brake caliper
Inspect the brake circuit and verify the brake charge pressure remains between 12000 and 15000 kPa using the steps on page 206. Check the parking brake caliper mounting bolts and tighten them to 244 N¥m as specified on page 151.
Manual Section: Removal and Repair of Axles and Brakes p. 206Frequently Asked Questions
How to troubleshoot weak hydraulics on John Deere 4400 with 430 loader?
To troubleshoot weak hydraulics, first check for low pump flow or low hydraulic oil level. For the 4400 model, the hydraulic pump flow should be 66 l/min (17 gpm) at 2200 engine rpm. If the flow is low, the pump may need repair or replacement, or the hydraulic tank may need to be filled to the correct level. p. 199
What is the minimum engine speed at torque converter stall for the 4400 and 4500 Telescopic Handlers?
The minimum engine speed at torque converter stall for the 4400 and 4500 Telescopic Handlers is specified as 2050 rpm. This information is found in the basic information section of the transmission specifications. p. 19
What is the specified torque for the gearbox mounting screws?
The gearbox mounting screws should be tightened to a torque of 98 N¥m (72 lb-ft). This torque setting is provided in the torque settings section for gearbox removal and replacement. p. 36
What is the torque specification for the parking brake caliper mounting bolts?
The mounting bolts (C) for the parking brake caliper should be tightened to 244 N¥m (180 lb-ft). This torque setting is crucial for ensuring the proper installation and function of the parking brake caliper. p. 151
What is the open circuit voltage for a 100% charged battery?
A fully charged battery should exhibit a stabilized open circuit voltage of 12.6 Volts or More, which corresponds to a 100% charge. This measurement is used to determine the state of charge of the battery. p. 226
