Knowledge Corner – NT855 & XL250K

The NT855 is an inline 6-cyl, 14 L turbocharged/after-cooled diesel with the famous PT fuel system. Its replaceable wet liner and dual-valve cylinder head allow an in-field overhaul in 8 h, cutting downtime for pavers, cold planers and cold recyclers such as the XCMG XL250K. The XL250K uses full-power PTO to drive a 2.5 m milling & mixing rotor; engine rated 298 kW @ 2,100 rpm meets EU Stage II / China III emission.

Field Failure & Solution

Issue: XCMG XL250K (S/N 1103021) suffered low power & white smoke.
 Root Cause: NT855 injector 4914452 nozzle worn, fuel drip into cylinder.
 Solution: Replace with Growshine genuine 4914452, recalibrate PT pump, road-test 2 h—power restored to 298 kW, smoke ≤1.0 m⁻¹. Always use 5 µm fuel filter 3315843 to extend injector life.
