Part of the New Holland Repair Manuals.
Looking for a New Holland D150 repair manual PDF you can trust? All 376 pages of this factory book (OEM #604.13.517.00) cover the D150 crawler dozer in every configuration: STD PAT PS, STD BD PS, XLT PAT PS, and LGP PAT PS. You get full hydraulic schematics for the dozer equipment circuit, wiring diagrams for the electrical system, and page after page of tightening torques. Open to the transmission section for torque converter, speed clutch, and modulating valve rebuilds, then hit the undercarriage pages for track chain tension and roller work. Torque the front bearing stop screws to 4.1 to 4.9 daNm (30.24 to 36.14 ft lb), and top the rollers and track chains with 4 L of oil. A dozer parked in the dirt earns nothing. Bookmarked and keyword-searchable; open it on any device and start wrenching.
