Case Farmall 115A Tractor Service Manual (51696992) (October 2020)

These Farmall 105A tractors usually live in dirt, dust, and weather—feeding, mowing, hauling, running loaders all day. This service manual walks you through how to trace problems step by step so you don’t just throw parts at it. Say the tractor won’t pull right in 4WD: you’d check linkages, inspect oil, test pressures or engagement, and verify what’s actually failed before you ever order a major component.

Applications & Use Cases

• Track down hydraulic issues by following the factory sequence to isolate whether it’s the pump, valve, or cylinder before you start swapping parts.
• Chase electrical gremlins with proper wiring routes so you can trace a dead circuit, check connectors, and verify grounds instead of guessing.
• Sort out driveline complaints like vibration or noise using the step order to inspect, align, and test axles, joints, and hubs.
• Do scheduled services right by seeing how to bleed fuel or brakes, route filters and hoses correctly, and check adjustments in the right order.
• Prep for bigger tear-downs so you can isolate the real fault, plan parts, and avoid tearing into the wrong section.

FAQ

Q: Is this a searchable PDF or just page scans?

A: It’s typically a PDF you can search by word, so you can jump to systems or procedures pretty quickly.

Q: Can I print just the sections I need for the shop?

A: Yes, you can usually print individual pages or chapters, which is what I’d do so you’re not dragging a laptop through the mud.

Safety Note

Always support and block the tractor securely before working under it or pulling driveline or axle components.
