Part of the John Deere Repair Manuals.
This is the John Deere Component Technical Manual CTM4687 for the AS Series and MS Series front wheel drive axles: AS-2025, AS-2035, AS-2035N, AS-2045, AS-2060, MS-2025, MS-2035, and MS-2045. Its 182 pages are a stand-alone service guide for these axles alone.
These axles are fitted to a wide range of John Deere machines, including the 6020 through 6920 series tractors and the 310G, 310SG, 315SG, 410G, and 710G. The manual walks through the steering cylinder and tie rods, planetary drive and wheel hub, knuckle housing and drive shafts, and the axle housing and differential, with removal, repair, and installation for each, plus a section on how the axle operates.
Because it is a component manual, use it alongside the machine technical manual; Triple Link Suspension is covered separately. It gives the torque values, clearances, and procedures needed to rebuild the axle correctly.
