Part of the John Deere Repair Manuals.
All 470 pages of this John Deere 325, 345 Technical Manual PDF (OEM TM1574 Feb-95) exist to get your Lawn and Garden Tractor running right, whether you're wrenching on the 325's FC540V engine or the 345's FD590V. Inside you'll find full electrical schematics covering power, cranking, and ignition circuits, a hydraulic lift system diagram with oil flow and pressure checks, and troubleshooting charts that walk you through both engines step by step. You also get complete torque value tables and hydrostatic transmission procedures for both models. Set your spark plug gap to 0.76 mm and torque it to 20 N·m, then check fuel pump pressure against the 6.12 kPa minimum before you chase a phantom no-start. No more flipping through a shop manual missing half the wiring. This bookmarked, searchable PDF jumps straight to whichever system you're chasing, on your laptop or your phone in the shop.

John Deere 325, 345 Common Problems This Manual Covers
John Deere 325/345 engine dies every few minutes while mowing, needs choke to restart
Test fuel pump output before condemning the carburetor. On page 27, minimum flow is 65 ml per 15 seconds (2.2 oz) at 6.12 kPa (0.90 psi) minimum pressure. Remove the pump and check for disintegrated diaphragm material; black rubber debris in the fuel bowl means the carburetor needs full disassembly and cleaning before reinstalling a new pump.
Manual Section: 325 Engine p. 27Engine cranks but won't fire, or fails to start at all on random occasions
Check battery voltage and connections first; a healthy system holds the full 12V rating listed on page 12. Clean and tighten the battery cables and starter connections. Test the Interlock Module (A2) output separately and replace it if intermittent no-start continues after charging, as issues with the interlock module can prevent cranking.
Manual Section: Electrical p. 158Oil is leaking from the right cylinder and pooling inside the muffler housing
Pull the right-side spark plug and check for wet fouling, a sign oil is bypassing into the cylinder. Inspect the valve guide clearance and piston rings for wear; oil capacity with filter runs 1.9 L (4.0 U.S. pt) on page 93, so track consumption between changes. Replace worn valve guides or piston seals and retest for leakage into the muffler.
Manual Section: 345 Engine p. 93Mower spindle keeps spinning more than 5 seconds after the PTO is disengaged
Time the spindle from PTO disengagement with a stopwatch. Inspect the PTO brake pads for glazing or wear and check spring tension on the brake arm. Replace the brake assembly if drag is insufficient, and verify blade balance isn't adding rotational inertia that extends stopping time.
Manual Section: Mower Decks Troubleshooting & DiagnosisCoolant warning light stays on the dash despite the engine running at normal temperature
Check coolant level in the overflow tank and radiator cap seal; opening pressure should read 73-103 kPa (10.5-15 psi) per page 91. Inspect the coolant temperature sending unit and its wiring connector for corrosion, since a false signal often triggers the dash light without an actual overheating condition. Bleed air from the system and retest after topping off coolant.
Manual Section: 345 Engine p. 91Frequently Asked Questions
What are the torque specifications for John Deere 325 engine mounting bolts?
For the John Deere 325 engine, the engine mounting cap screw torque is 16 N•m (144 lb-in.). The cylinder head cap screws require an initial torque of 32 N•m (24 lb-ft) and a final torque of 52 N•m (38 lb-ft) when lubricated. Connecting rod cap screws should be tightened to 20 N•m (177 lb-in.). p. 27
