Purchase and Installation Notes
- Verify Codes: Sany 60311933 + Isuzu 898173-3420 to avoid incorrect parts
- Replacement Recommendation: Replace all 6 in a set to prevent uneven heating of pistons due to new and old nozzles
- Installation Torque: 18–22 N·m. Over-tightening may cause thread stripping; under-tightening may lead to pressure loss and oil leakage
- Fault Diagnosis: For high-temperature poor performance, piston crown burning, or cylinder scoring, first check if the cooling nozzle is clogged or broken
