Part of the New Holland Repair Manuals.
This 837-page New Holland LS180.B, LS185.B, LS190.B Repair Manual (OEM #604_13_552_01) covers every skid steer system, from the primary hydraulic power circuit to the working arm and boom. You get complete wiring diagrams with pinout charts, hydraulic schematics for the primary, secondary, and high-flow systems, and a full section of error codes and troubleshooting steps for chasing down electrical faults. Engine, transmission, axles, and final drive procedures are all laid out step by step, alongside exploded views for parts identification. Set the right hand hydraulic pump's shoe-to-piston free travel at 0.13 mm, and torque the hydrostatic pump housing bolts to 91-111 Nm before startup. No more chasing a hydraulic leak with guesswork and a torque wrench you're not sure about. Bookmarked by section so you can jump straight from Distribution Systems to Power Train, this PDF opens on your laptop, tablet, or phone right on the shop floor.
