All part numbers are cross-referenced against OEM specs for direct matching.\u003c\/p\u003e\n\u003cp\u003ePart numbers: BM76340, AR12110, AR12111, AR12112\u003cbr\u003eFits: Cummins NT855, K19, M11 diesel engine\u003cbr\u003ePosition: PT fuel pump vibration damping assembly\u003c\/p\u003e\n\u003cp\u003eWhat you are ordering\u003cbr\u003ePrice is per vibration damper assembly. All part numbers are separate variants, please select the correct PN from variant options. These damper assemblies are not interchangeable. Different part numbers have different damping rates, inlet size and mounting dimensions. Wrong selection will cause excessive fuel pump vibration, fuel pressure fluctuation, rough running and accelerated wear of fuel pump internal components.\u003c\/p\u003e\n\u003cp\u003eSpecifications\u003cbr\u003eStructure: integrated viscous vibration damper assembly\u003cbr\u003eDamping medium: high stability viscous fluid\u003cbr\u003eHousing: high strength alloy housing\u003cbr\u003eFinish: wear-resistant \u0026amp; anti-corrosion treatment, pressure and damping tested before packing\u003cbr\u003ePacking: individual protective box, marked with part number\u003c\/p\u003e\n\u003cp\u003eWhen to replace\u003cbr\u003eVibration damper suffers viscous fluid aging, seal leakage and performance decay after long running hours. Common failure signs: obvious fuel pump vibration, fluctuating fuel pressure, engine hunting, abnormal noise from PT pump. Replace the matched damper assembly together when damping performance drops, and inspect fuel pump mounting bolts and bracket at the same time.\u003c\/p\u003e\n\u003cp\u003eFitting notes\u003cbr\u003eStrictly confirm the mounting dimension and port size before assembly. Do not install dampers of different part numbers interchangeably. Follow Cummins service manual for torque and installation procedure. If you are not sure which PN matches your engine CPL, send us engine serial number for confirmation.\u003c\/p\u003e\n\u003cp\u003eWarranty and shipping\u003cbr\u003eCovered by a 12-month warranty against manufacturing defects.
