John Deere 737, 757 Common Problems This Manual Covers
Engine burning oil excessively, blue smoke on startup, compression test reads low
Run a compression test on both cylinders; minimum spec is 390 kPa (57 psi) per page 13. Low readings combined with excessive oil consumption point to worn top piston rings. Pull the piston and measure ring end gap: wear limit is 0.65 mm (0.026 in.) and side clearance limit is 0.18 mm (0.007 in.) per page 17.
Manual Section: Engine DiagnosisMachine won't drive straight, pulls to one side under heavy load on slopes
Verify hydraulic oil is filled to 9.5 L (2.5 gal) capacity per page 174. Bleed the hydrostatic system to purge trapped air, then check both motion control linkages for equal neutral positions. If drift or sluggishness persists under load, inspect the hydraulic schematic and test pump flow per the Hydrostatic Power Train Diagnostics section.
Manual Section: Hydrostatic Power Train DiagnosticsDeck belt shredding repeatedly after short service life, PTO slipping under full engagement
Inspect the mule belt tensioner spring length: it should measure 166-187 mm (6.50-7.375 in.) per page 259. A sagged spring lets the belt slip and wear out fast. Check PTO clutch coil resistance with an ohmmeter: spec is 1.7-1.9 ohms per page 87. Replace the clutch if resistance is out of range or air gap is uneven across the rotor.
Manual Section: Attachments DiagnosticsCrankshaft oil seal leaking, oil pooling under machine after every mowing session
Remove the pump drive sheave, noting the nut torques to 46 N·m (34 lb-ft) per page 175 on reinstallation. Inspect the crankshaft journal for wear grooves before fitting a new seal. A grooved shaft needs a Speedy Sleeve first or the replacement seal will weep immediately. Press the new seal in flush per page 16.
Manual Section: Engine p. 16Frequently Asked Questions
What are the torque specs for the engine bolts on John Deere 737 and 757?
The engine mounting cap screws should be torqued to 40 N•m (30 lb-ft). This specification is found under the 'Repair Specifications' for the engine. p. 15
What are the replacement specifications for Engine motor (complete replacement)?
For a complete engine replacement, the models are FH680D (17.2 kW / 23 hp) or FH721D (18.6 kW / 25 hp), both Kawasaki OHV, horizontal shaft, 4 cycle, 90° V-twin engines. The engine mounting cap screws should be torqued to 40 N•m (30 lb-ft). If the engine has been rebuilt, the oil should be changed after the first 20 hours (maximum) of operation. p. 13
How do you fix john Deere 737 engine leaking oil, excessive crankcase pressure, backfires under load?
Test crankcase vacuum per ; maximum is 10.2 cm (4 in.) of water movement. Positive pressure instead of vacuum confirms worn piston rings or a failed head gasket. Verify compression in both cylinders: minimum acceptable is 390 kPa (57 psi). Torque cylinder head cap screws to 25 N·m (19 lb-ft) after any head removal.
How do you fix valve guides seizing after overheating, grass and debris packed into engine cooling fins?
Remove shrouding and blow out all grass packed around cooling fins and the oil cooler before diagnosing further. Overheating is the primary killer here. Pull the valves and measure guide ID: new spec runs 6.000-6.012 mm (0.2362-0.2367 in.) and the wear limit is 6.08 mm (0.239 in.) per page 64. Replace any guide at or beyond that limit. p. 64
