Part of the Case Repair Manuals.
The 521D is Case's compact wheel loader, and when the hydraulics quit or it will not start after a wet day the machine sits idle. This is the real factory service manual, part 6-40745, 1,018 pages covering the diesel engine, fuel, electrical, steering, power train, brakes, hydraulics and mounted equipment, plus full electrical and hydraulic schematic foldouts. Whether you are chasing a total loss of bucket control, a no start after water, or an articulation lock that will not work, it is here in factory order with the capacities and torque values to work to.
