Part of the John Deere Repair Manuals.
All 525 pages of this John Deere 2155 technical manual (OEM TM4436) focus on a single goal: restoring the 2155, 2355N, 2355, 2555, 2755, 2855N, 2955, and 3155 tractors to factory condition. You get full wiring diagrams tracing every circuit from the charging system to the cab HVAC, hydraulic schematics routing the complete rockshaft and selective control valve circuits, a thorough troubleshooting section that works through electrical and mechanical faults system by system, and step-by-step procedures for the power train, Hi-Lo shift unit, FWD disk clutch, and hydrostatic steering. Pressure-test your cooling system to 50-70 kPa (7-10 psi); the intake vacuum limit for a clean air element is 6 kPa. Every hour that tractor sits costs money. Download it now, open any section in seconds using bookmarked navigation, and get the factory answer on your first look.
