Looking for the New Holland RG140.B, RG170.B, RG200.B service manual PDF? This 803-page factory manual (OEM #75314236) walks you through every system on all three motor grader variants, from the transmission and tandem drive axles to the articulation joint and front blade. You get full electrical wiring diagrams (pp. 80-97) and hydraulic system diagrams, and a complete transmission section with pressure checks and troubleshooting charts. Inside: standard torque tables, fluid and lubricant capacities, and step-by-step removal and installation procedures for the engine, turbocharger, limited slip rear axles, brakes, and air conditioning. Torque the hub cap capscrews to 40-54 Nm, and confirm transmission filter bypass at 60 psi before you chase a shifting complaint. Your grader is down and the clock is running. Get the factory numbers, not forum guesses. Bookmarked by system tab; type a keyword, jump to the spec, and get back on the blade.
