Key Design Features
Boost Compensation
Integrated turbo boost pressure sensor diaphragm adjusts fuel delivery for optimal combustion efficiency and reduced smoke.
Cold-Start Assist
Optional manual cold-start enrichment device (increases fuel during startup) for improved performance in extreme cold.
Fuel Control
Fuel delivery regulated via rack-and-pinion; governor maintains RPM stability.
Durability
Precision-ground plunger/barrel assembly and hardened camshaft ensure longevity (>100,000 hours).
Common Applications
Construction Machinery: Excavators (e.g., Sumitomo SH120), loaders, bulldozers
Commercial Vehicles: Isuzu ELF trucks (NKR/NPR series), bus chassis
Generators: 50-150kVA diesel generator sets
Replacement & Maintenance Guidelines
Timing Calibration
Strict alignment of engine timing marks (flywheel notch + pump pointer) required during installation.
Rack Position Reset
Rack travel must be reset after disassembly to prevent overspeeding or power loss.
Seal Replacement
Overhaul kits must include plunger O-rings, delivery valve seals, etc., to prevent leaks.
Professional Calibration
Post-repair test bench calibration essential for fuel delivery/timing accuracy (±3% cylinder balance).
Critical Notes
Fuel Requirements: Use low-sulfur diesel compliant with ISO 4113 to prevent plunger corrosion.
Counterfeit Risk: Beware of remanufactured/imitaiton pumps; purchase from authorized channels (authentic pumps have laser-etched codes).
Alternative Parts: If discontinued, consider upgraded models 101605-0290 or DENSO PE6P series (verify compatibility).
Failure Symptoms
Pump malfunction may cause:
✅ Hard starting
✅ Power loss/weak acceleration
✅ Black/white exhaust smoke
✅ Unstable idle/stalling
✅ Abnormal fuel consumption
