Wrenching on a Deere crawler? This 857-page John Deere 350C, 350D, 355D Technical Manual PDF (OEM TM1115) walks you through the crawler bulldozer and crawler loader, from track systems to backhoe hydraulics. You get factory wiring diagrams for the charging, lighting, and harness circuits, hydraulic schematics for the loader, dozer, winch, and backhoe, plus a full System Testing section with operational checkout procedures for the engine, power train, and electrical system. Page after page of torque tables runs from M5 hardware up to 1-1/4 inch bolts. Set axle shaft end play at 0.001 to 0.005 inch, and pressure-test the power shift clutch for leakage at 10 psi before you button it back up. No more chasing wiring faults with a multimeter and a prayer. Bookmarked with a full text layer; jump to any section or type the spec you need.

John Deere 350C, 350D, 355D Common Problems This Manual Covers
John Deere 350C engine starts fine then dies after a few minutes, restarts and stalls again
Check the return line check valve first; the ball check sticks and blocks fuel return, starving the engine. Remove the valve, clean the ball and spring, and verify free movement. Confirm the 22 gal fuel tank has fuel and inspect the fuel filter. Work through the engine troubleshooting charts starting if stalling continues.
Manual Section: Engine TroubleshootingMachine drifts to one side, steering lever pulls hard and won't disengage the clutch fully
Test the steering clutch for internal leakage before pulling anything apart. Regulate 10 psi (1 kg/cm²) of air pressure into the clutch system with the needle valve open, following the procedure on page 127. Escaping air means worn discs or piston seals. Adjust the brake bands first; if drift returns quickly, plan a clutch pack replacement.
Manual Section: Axles and Suspension System p. 127Final drive housing runs hot and leaks gear oil at the axle seal
Drain the final drive and inspect the oil for metal. Replace seals and bearings as a set, then measure axle shaft end play; the spec is 0.001 to 0.005 inch on page 121. Verify rolling torque during reassembly: 90 to 115 lb-in with new bearings, 70 to 85 lb-in with used bearings, per page 122.
Manual Section: Axles and Suspension System p. 121Engine cranks slowly or refuses to start at all on cold mornings below freezing
Load-test the battery and clean both terminals before blaming the engine. Check the glow plug circuit for continuity and verify each plug heats. If cranking is strong but starting stays hard, run a compression test; healthy diesel cylinders read 350 psi, listed on page 832. Wiring checks for the starting circuit begin on page 340.
Manual Section: Electrical System p. 340Track keeps coming loose, throwing off the sprocket, grousers worn down flat
Measure grouser height before adjusting anything: new shoes measure 1.58 in. and the wear limit is 0.75 in., shown on page 46. Check track chain pitch against the 23.03 in. new spec on page 50 to catch stretched chains. Torque track shoe bolts to 110 lb-ft (149 N-m) per page 19 after any shoe work.
Manual Section: Tracks p. 46Loader bucket lifts slowly under load and blade drops instead of staying raised
Test system relief pressure first: loader circuits should hold 2250 psi, listed on page 846; bulldozer circuits hold 1750 psi, page 844. Low readings point to a worn pump or stuck relief valve. If functions drift down with the engine off, inspect cylinder packings and control valve spools for internal leakage past the seals.
Manual Section: Main Hydraulic System p. 434Frequently Asked Questions
What are the replacement specifications for the fuel filter?
For maximum filter life, sediment and water should not be more than 0.10 per cent. The cetane number should be 40 minimum. p. 23
What is the torque specification for the track shoe cap screws?
Track shoe cap screws should be checked periodically for tightness and tightened to 110 lb-ft (149 N-m) torque. p. 19
What is the correct engine oil pressure at normal operating temperature?
With the engine at normal operating temperature and running at 2500 rpm, the oil pressure reading should be 50 ± 15 psi (345 ± 103 kPa). p. 715
What is the correct fan belt tension for the engine?
The fan belt should be adjusted to 0.75 inch (19.05 mm) deflection when 20 pounds (89 N) of force is applied halfway between the pulleys. p. 716
What is the cylinder head bolt torque specification for the engine?
The cylinder head to block cap screw torque is 95 lb-ft (129 Nm). After 30 minutes of run-in at 3/4 to full load, loosen bolts 5 to 10 degrees and retighten one at a time to 95 lb-ft. p. 286
