Make / Family Applications
John Deere 210C, 310A, 310B, 310C, 350D, 401D, 444D, 455D, 610B and related applications using the listed injector family

Product Overview

A worn injector can cause poor fuel atomization, hard starting, uneven idle, smoke, excessive combustion noise or reduced power. Replacing an injector that fails opening-pressure or spray-pattern testing can restore more even cylinder combustion.

Cross-reference catalogs tie this injector family to a broad range of Deere machines, including 210C, 310A/310B/310C, 350D, 401D, 444D, 455D and 610B. Deere used different injectors across engine and serial ranges, so the existing injector/reference number remains the best fitment check.

Key Features & Performance

  • Mechanical diesel injector/nozzle for older John Deere engines
  • Cross-referenced to AR89564 and related Deere injector numbers
  • Addresses poor spray/opening behavior when the original injector is worn

Technical Details

  • Component type: mechanical diesel fuel injector / nozzle assembly
  • Application: John Deere construction/industrial diesel equipment
  • Service best practice: verify opening pressure/spray and use clean fuel-system procedures

Frequently Asked Questions

Q: Will this fit every machine listed regardless of serial number?
A: No. Verify the injector number against the engine serial/parts catalog.

Q: Can worn injectors cause smoke?
A: Yes. Poor atomization or incorrect opening behavior can contribute to smoke and uneven combustion, although compression and pump timing should also be checked.

Confirm injector/reference number for the exact engine serial range.
