When a split tractor is waiting on you and planting weather won't, 594 pages of factory procedure are the difference between a weekend job and a lost week: this New Holland 1715 service manual PDF (OEM ID 40132030) covers all five compact diesels in the line, from the 1320 to the 1720. Wiring diagrams trace the charging, starting, and glow plug circuits, while hydraulic schematics map the pump, remote valve, and control valve assembly. Tractor separation alone fills nearly a third of the book, and the gear, hydrostatic, and 12 X 12 synchromesh shuttle transmissions each carry their own overhaul section. Set the hydrostatic high pressure relief valve to 3981 psi (274 bars) on the 1320/1520 and pull connecting rod caps to 36.2-39.8 lbs. ft. on the 1320/1520/1720 during your rebuild. Nothing stalls a teardown like one missing torque figure. Bookmarked for quick jumps, the PDF rides along wherever the tractor quit, field edge or shop bench.
