John Deere 3375 Skid Steer Loader Technical Manual (TM1565)

What's Covered in This Manual

This is the Technical Manual (TM1565, September 1994 printing) for the John Deere 3375 skid steer loader, covering machines from Serial No. 130001 onward, and published by John Deere's Lawn & Grounds Care Division - the same division behind John Deere's commercial grounds equipment, reflecting how this skid steer was positioned in the product line. The engine is a John Deere-badged Yanmar 3TN66 diesel, and the manual's fuel and specifications sections cover it in full, from diesel fuel specifications and storage through complete engine specifications.

Unlike manuals organized by section number, this one identifies each major section with a symbol rather than a number, with groups and pages numbered consecutively within each section - the engine, electrical, power train, hydrostatic power train, steering, brakes, and hydraulics each get their own section in that format. Every section follows the same structure where applicable: specifications, theory of operation, troubleshooting diagrams, diagnostics, tests and adjustments, and repair - giving a technician both the conceptual understanding of how a system works and the hands-on procedure for fixing it.

The hydrostatic power train section is particularly important on a skid steer like this one, since it's what drives the machine and both of its tracks or wheels independently for steering - the manual covers its theory of operation and diagnostic testing in detail alongside the separate steering and brakes sections. Combined with the hydraulics section covering the loader's lift and tilt functions, this manual gives a technician everything needed to diagnose and repair a 3375 correctly, from the engine through to the attachment-end hydraulics.
