Part of the John Deere Repair Manuals.
Need the real factory service data for your John Deere 4055 shop manual PDF? This 203-page OEM reference covers the entire 55 Series: 4055, 4255, 4455, 4555, 4755, and 4955 tractors. Inside: hydraulic schematics with full fluid routing, wiring diagrams for the Intellitrak Warning System and charging circuit, and a troubleshooting section for chasing electrical and fuel faults before pulling parts. You get complete overhaul procedures for both Perma-Clutch and Power Shift transmissions, injection pump static timing, viscous fan clutch service, and brake system work including accumulator rebuild and brake valve adjustment. Brake piston diametral clearance in the bore runs 0.003–0.007 inch; on Quad-Range models, retire Perma-Clutch discs once thickness drops below 0.110 inch (2.79 mm). Your tractor is parked and the clock is running. Search any spec by keyword, jump to any section in seconds, and bring it right to the shop floor.
