Part of the Case Repair Manuals.
This is TM 5-3805-292-23, the U.S. Army field maintenance technical manual dated January 2010. It covers the M400T tracked and M400W wheeled skid steer loaders. The engine is the Iveco F5C 3.2 L turbo diesel, rated 69 hp (51 kW) net. The book also covers the hydrostatic drive, loader hydraulics, cab, ROPS and the 24 volt electrical system.
A guessed relief setting or a borrowed torque value is how a pump gets cooked or a bolt lets go. This book gives the real checkout numbers: main relief at 3,000 ± 50 psi, a 362 psi minimum charge pressure at full throttle, and intake and exhaust valve lash.
You also get troubleshooting charts, PMCS tables, chain case and track work, attachments and the electrical schematics.
