advantages & highlights
✅ OEM-Exact Performance for Industrial Applications
Matches Cummins/Bosch calibration for timing, delivery volume, and pressure - critical for engine power and smoke control.
✅ Superior Durability in Extreme Conditions
Oil-lubricated design + cast iron housing withstands dust, vibration, and continuous duty - ideal for mining, desert, and Arctic operations.
✅ Fully Rebuildable & Field-Serviceable
Unlike sealed common-rail pumps, the P-type can be overhauled on-site - saving 60% vs. new. We supply complete rebuild kits.
✅ High Pressure for Modern Injectors
Supports upgraded nozzles (e.g., 6-hole, 0.18mm) for cleaner combustion - compatible with Tier 2/Stage IIIA retrofits.
✅ Universal Fit Across Machinery Brands
One pump fits Komatsu, CAT, SANY, XCMG, John Deere - simplifies inventory for equipment dealers.
✅ Precision Calibration Guaranteed
Every pump tested on Bosch EPS 815 bench / Delivery volume @ 1000 RPM/ Governor cut-off (2800 ± 20 RPM)
Plunger-to-barrel leakage (<0.5 mL/min)
✅ Cost-Effective Alternative

FAQ:
Q1: 4327066 used on Komatsu PC200-6 with 6D102 engine?
✅ Yes - but only if repowered with Cummins 6BT 190 HP. Original 6D102 uses Komatsu pump. Verify via engine tag: 6BT 5.9 190.
Q2: Can I use this on a 230 HP 6BT?
❌ No. 4327066 is for 160–190 HP only. For 215–230 HP, use Cummins 3550222 (higher delivery rate).
Q3: Does it require engine oil lubrication?
✅ Yes. Unlike VE pumps, the P-type has an oil inlet port (1/4" NPT) connected to engine oil gallery. Failure to connect oil feed causes rapid bearing wear.
Q4: What's included in the rebuild kit?
Our RK-4327066 Kit includes:
6 × Plunger/barrel pairs (graded) 6 × Delivery valves + springs Governor weights, springs, thrust bearing
All seals (FKM), gaskets, O-rings Calibration chart & torque specs
Q5: Can it be used with biodiesel?
✅ Yes - up to B20, with FKM seals. For B100, we offer FFKM seals (extra USD 45, MOQ 10 pcs).
Q6: Warranty and testing?
24-month warranty (new), 12-month (reman)
Every unit bench-tested (Bosch EPS 815) Batch-traceable (laser-etched code)
Q7: MOQ and lead time?
MOQ: 1 pc (new), 5 pcs (reman) / Samples: Available (DDP)
Lead Time: 5 days (stock); 15 days (custom calibration)
Q8: Do you supply installation support?
✅ Yes - included:
Timing mark diagram (TDC offset: 22°–28° BTDC)
Torque specs (flange: 45 N·m; delivery valves: 85 N·m)
