1995 John Deere 325 & 345 Lawn and Garden Tractors Technical Manual (P/N TM1574)

John Deere publication TM1574 (February 1995) covers the 1995 John Deere 325 and 345 lawn and garden tractors, with the single-cylinder, air-cooled FC540V in the 325 and the V-twin, liquid-cooled FD590V in the 345. Electrical pages include April 1995 revisions.

Text search and diagram navigation: Service text is searchable, but labels in several circuit-operation diagrams are not. Embedded bookmarks cover the major sections, with some incorrect destinations. Small wiring labels require zooming. An appended component-location extract is cropped on the right; the full 325 component-location drawing is also included.

• Engine repair: Engine removal, cylinder-head and valve service, piston and connecting-rod inspection, crankshaft work, and oil-pump repair.

• Fuel and cooling: Carburetor rebuilding, fuel-pump testing and replacement, plus radiator, thermostat and water-pump service for the 345.

• Electrical diagnosis: Separate model schematics, ignition-module and pulser-coil tests, starter motor bench tests, and electric PTO clutch testing and air-gap adjustment.

• Hydrostatic transmission and brakes: Transaxle teardown, neutral creep adjustment, transmission efficiency tests, differential service, and internal wet disk brake inspection.

• Steering and hydraulics: Mechanical steering gearbox overhaul, hydraulic steering-valve service, cylinder leakage testing, and hydraulic lift control valve repair.

• Mower attachments: Deck leveling, drive-belt replacement, spindle rebuilding, and blade sharpening and balancing, supported by exploded assemblies and spindle cross-sections.

Written for experienced technicians, this manual assumes familiarity with workshop service and the test equipment specified for each procedure.

Engine, Fuel and Cooling Repair

Engine diagnosis: The 325 section includes automatic compression release checks; the 345 adds cylinder leak-down testing with the JDG472 adapter. Wear-analysis sections address pistons, rings, valves, crankshafts and connecting rods. Engine and fuel-system troubleshooting charts cover hard starting, erratic running and low power.

Carburetors and fuel pumps: The 325's plastic carburetor float is nonadjustable; the 345 has a float-level adjustment procedure. Fuel-pump coverage distinguishes the 325's vacuum-pulse pump from the 345's mechanical pump. Exploded carburetor and oil-pump views accompany the repair procedures.

Cooling-system coverage includes radiator-cap pressure testing, thermostat opening checks and water-pump disassembly, with inspection criteria for the shaft and housing.

Electrical Schematics and Fault Diagnosis

The Standard Schematic 325 and Standard Schematic 345 are supported by component-location drawings and a wire-color abbreviation chart. Model-specific circuit diagrams, including PTO Circuit Operation—PTO On, show the electrical paths for the operating condition being diagnosed.

Short-circuit and ground-circuit tests accompany diagnosis tables that connect numbered test locations with normal readings and follow-up checks. This helps a technician trace starting or PTO-engagement faults to the affected circuit before replacing components.

Wiring coverage: The 325 main wiring-harness drawing listed as page 4-13 is missing from this PDF. The 325 standard schematic and auxiliary-harness drawings are included.

Hydrostatic Transmission and Brakes

Internal repair covers the pump and motor rotating groups, swash plate, bypass valves and differential. The Transaxle Operation—Gear Power Flow drawing follows the drive path to the axle shafts.

Assembly views identify the brake shim used on early models. The transmission repair section also warns that incorrect filter-spacer orientation can cause internal transmission damage.

Steering and Hydraulic Lift

The 325 uses a recirculating-ball steering gearbox; its repair section includes input-shaft bearing preload adjustment. The 345 has hydraulic power steering, with valve disassembly, steering-cylinder leakage tests and the KML10018-3 spring installation tool identified for valve assembly.

The Hydraulic/Hydrostatic Schematic connects the transmission supply with the steering and lift circuits. Lift-valve repair distinguishes the matched spool and valve body from serviceable seals; lift-cylinder coverage provides removal and installation procedures.

Mower Deck and Chassis Repair

Attachment sections cover 38-, 44-, 48- and 54-inch mower decks. The 44-inch spindle cross-section distinguishes rear-discharge and mulching blade configurations.

The spindle procedures warn that clamping the shaft's hex end in a vise can damage it and affect blade operation. Chassis repair includes front-axle bushings, wheel bearings and removal of body panels for service access.

Specification and Reference Data

Torque tables and tolerance charts cover crankshaft end play, valve train clearance, fluid capacities, wear limits and electrical test specifications.

Follow the manual's precautions for rotating mower blades, supported machinery and pressurized hydraulic lines during service.
