Engine Overhaul Guidelines
Engine life and performance will vary depending on
operating conditions and the level of regular engine
maintenance. Engines can be brought back to original
performance standards through proper overhaul procedure
and replacement of parts with genuine John Deere service
parts. Overhauling the engine prior to failure can avoid
costly repairs and downtime.
Consider installing a John Deere overhaul kit when:
• The engine begins to experience power loss and there
are no known engine component failures.
• The engine is hard to start due to low cranking
compression.
• The engine begins to smoke and there are no known
engine component failures.
• The engine begins to use oil. Refer to Section 04 for
acceptable oil consumption.
• The engine has high usage hours and the owner wants
to take preventive measure to avoid high-cost repairs
and costly downtime.
John Deere overhaul kits have a 1500-hour or 12-month
warranty, whichever comes first. Installation labor is
covered by warranty if an authorized John Deere dealer
installed the overhaul kit and the replacement parts.
