Part of the John Deere Repair Manuals.
All 162 pages of this John Deere 730 Technical Manual PDF (OEM CTM4820) zero in on the front-wheel drive axles fitted to the 730, 733, 740, 745, and 750. Inside: sectional and exploded views of the planetary drive, knuckle housing, steering cylinder, and differential, backed by full torque tables and fluid capacity data. You get step-by-step reconditioning procedures for the wheel hub, bevel pinion drive shaft, and self-locking differential, plus a troubleshooting section and a theory-of-operation breakdown explaining how the front axle and differential actually work. King pin preload on the 730 and 733 runs 0.5–0.6 mm; on the 740, 745, and 750 that spec shifts to 0.7–0.8 mm, with king pin cap screws torqued to 160–200 N·m. Your axle is apart and you're staring at a pile of shims. One-click download, search by keyword, find the spec, fix the machine.
