New Holland T3.50F, T3.55F, T3.65F, T3.75F Common Problems This Manual Covers
New Holland T3.50F engine starts fine but stalls out completely after 10 to 15 minutes
Inspect the fuel delivery system and injector pump. If the engine dies after a 10 to 15 minute interval, check the fuel lines for vacuum locks or contamination. Review the troubleshooting procedures. Replace the fuel injector O-rings and bleed the air from the lines.
Manual Section: Engine TroubleshootingTrailer brake warning light stays illuminated and hydraulic release pressure reads 0 to 11 bar
Test the trailer brake hydraulic control lines for blockages. If the gauge shows a release pressure of 0-11 bar, investigate the return valve for sticking. Consult the hydraulic schematic on page 430 to trace the flow path. Clean the valve body and replace the seals to restore pressure.
Manual Section: Trailer Brake Hydraulic Control Troubleshooting p. 430Main hydraulic lift fails to operate or drops implement immediately when placed under load
Verify the main lift system pump output with a diagnostic gauge. If the reading indicates a system pressure of 0 bar, tear down the assembly and check for worn hydraulic pump seals. Replace all damaged cylinder O-rings and retest the lifting capacity to ensure it holds steady.
