Part of the New Holland Repair Manuals.
A mini excavator that crawls straight on gravel but drags one track on the ramp usually has a travel motor problem, and pulling that motor without the bolt torques and the reassembly sequence turns a morning repair into a parked machine and an idle crew. This service manual is where those numbers live: 415 pages for the New Holland EC15, EC25, EC35 and EC45 crawler excavators, covering machines built around the Mitsubishi L3E, S4L, S4L-2 and S4Q2 engines.
The book is organized by system. Electrical System walks through the circuits, relays and diode block, and removal and installation of components. Hydraulic System carries troubleshooting charts and valve bank service. Operator's Platform covers the ROPS/FOPS unit, cab and heater, and Traction/Undercarriage handles the dozer blade, its cylinder and the rubber tracks.
It is a searchable PDF you download and keep. Print the page you need and let it get dirty on the bench; the file stays clean.
