1973–1979 John Deere 2130 Tractor Technical Manual PDF (P/N TM-4272)

This technical manual for the 1973–1979 John Deere 2130 tractor is John Deere Werke Mannheim publication TM-4272. It covers cab and non-cab tractors and combines January 1979 material with individually revised pages.

• Engine repair: Cylinder-head and valve service, wet cylinder liners, pistons, connecting rods, crankshaft bearings, balancer shafts, lubrication and cooling-system repairs.
• Fuel-system procedures: Roto-Diesel injection-pump removal, installation, timing and bleeding, plus injection-nozzle cleaning, opening-pressure checks, spray-pattern assessment and leakage testing.
• Power train: Clutch adjustment, High-Low shift-unit diagnosis and overhaul, creeper transmission repair, collar-shift transmission inspection, differential adjustment and independent PTO service.
• Hydraulic diagnosis: Pressure and flow tests, radial-piston and transmission oil-pump repair, rockshaft adjustment, selective control valves, breakaway couplers and remote cylinders.
• Electrical systems: Bilux and sealed-beam wiring layouts, circuit and terminal identification, starter inspection, alternator component tests and voltage-regulator checks.
• Chassis and cab: Front-axle repair, manual and power steering, foot and hand brakes, hydraulic trailer brakes, wheels, seats, roll guards and cab equipment.

This manual is intended for experienced technicians with suitable workshop equipment and familiarity with agricultural machinery service.

Engine Repair and Roto-Diesel Fuel-System Coverage

Engine cross-sections, gear-train timing drawings and the cylinder-head tightening sequence support internal engine work. The procedures include liner protrusion checks, piston selection, bearing inspection, camshaft timing and balancer-shaft installation.

The liner instructions explain a specific assembly risk: soaking the packings and O-rings in oil can make them swell and become damaged during installation. Cooling-system coverage includes water-pump dismantling, impeller positioning and thermostat inspection.

Roto-Diesel coverage includes external service, pump timing and fuel-system bleeding. Internal pump repair and delivery/governor calibration are assigned to a specialized workshop with the required test stand; injection-nozzle testing and servicing receive separate procedures.

High-Low, Transmission and PTO Diagnosis

The power-train chapters distinguish the collar-shift transmission, High-Low shift unit and creeper transmission. A High-Low exploded view accompanies clutch and brake-pack work, while the transmission and differential procedures address shaft bearings, preload and gear backlash.

A useful diagnostic distinction connects High-Low trouble with hydraulic supply: rockshaft or remote-cylinder behavior helps separate a charge-circuit problem from a fault within the High-Low circuit. Independent PTO coverage differentiates single-speed and dual-speed arrangements and includes clutch, brake and control-valve service.

Electrical Variants and Circuit Tracing

Separate Bilux and sealed-beam sections distinguish earlier, later and cab-equipped wiring arrangements. Their diagrams and connection charts identify wires, terminals and components, helping the technician select the appropriate circuit before tracing a fault.

Starter and alternator chapters cover component inspection and electrical testing. Hydrostatic front-wheel-drive coverage is limited to related cab wiring and creeper safety-switch linkage procedures.

Hydraulic Testing, Rockshaft and Remote Equipment

Complete hydraulic oil-flow diagrams connect the transmission pump, main hydraulic pump, steering priority, High-Low unit, independent PTO and rockshaft. Diagnostic sections address slow operation, oil overheating, leakage and lift-arm settling before moving into individual component repair.

The rockshaft procedures cover load, depth and combined control adjustments. Separate sections treat spool-type and poppet-type selective control valves, their adjustments, breakaway-coupler repair and remote-cylinder rebuilding and bleeding.

Steering, Brakes and Cab Service

Manual and power-steering procedures include inspection, assembly and adjustment. Brake coverage includes valve repair, system bleeding, pedal adjustment, pressure rings, brake disks, the independent hand brake and hydraulic trailer-brake variants.

Tractor-separation and cab-tilting procedures support access to major assemblies. Additional sections cover wheel bearings, rack-and-pinion rear wheels, seats, roll-guard installation, cab glazing, ventilation and heating.

Selected Engine, Final-Drive and Hydraulic Reference Values

These figures are a small selection of the manual’s assembly and test data, with the relevant conditions retained.

Cylinder-head cap screws dipped in oil are specified at 130 Nm, alongside the prescribed tightening sequence and retightening after the specified engine run. Final-drive-to-transmission-case cap screws are specified at 120 Nm.

Hydraulic pump stand-by pressure is 155 bar (2250 psi), checked at rated engine speed with transmission oil at 50°C (120°F) using the specified test setup.

Heavy agricultural machinery and pressurized fluids require appropriate shop precautions. Relieve hydraulic pressure and securely support heavy components before carrying out repairs or applying reference values.

PDF Navigation, Readability and File Contents

Text search and diagram detail: The manual pages are scanned images without searchable manual text or PDF bookmarks. Use the scanned contents pages and section/group numbering for navigation; small wiring numbers and connector labels are readable when enlarged.

The download contains one printable English PDF with 454 pages: 422 pages of manual content, two cover pages and 30 blank or separator pages, all included in the total.
