microfractures and ultimately catastrophic engine failure.
2
Cylinder Liners
Small improvements are vital
Non-genuine cylinder liners don't include anti-polishing ringdesigned to scrape carbon deposits from the Piston so it can be burned in the next combustion stroke
Without this
carbon buildup can polish away the liner's crosshatch screws leaving excess oil in the combustion chamber and allowing combustion gases to enter the crankcase.

Piston Rings
Material and durability
Non-genuine piston rings have coatings and material hardness that may lead to delamination
Leads to
a shortened engine life cycle.
4
Piston Pins
Precision is valuable
Non-genuine piston pins failed to meet Cummins' precise dimensional standards
Leads to
a catastrophic pin joint seizure.
The combustion chamber contains hardest working components
if they fail so will your engine
5
Bearings
Key Support
Designed to support the rotation of key internal components like the crankshaft and connecting rods with minimal friction
To ensure Optimal Performance anything less than Perfection isn't going to cut it
Non-genuine connecting rod bearings were missing critical oiling grooves and could lead to improper oiling
Results in
a spun bearing and potential engine failure.
Main bearings and connecting rod bearings also fail to meet critical specifications for thickness or metallurgical composition
Results in
thermal fatigue and early failure
6
Head Gasket
Dimensions are crucial
The head gasket seals the combustion gases within the cylinders and prevents coolant or engine oil leaking into them.
If the head gasket fails you risk overheating the engine
The non-genuine head gasket failed their dimensional testing it was also missing a critical fluid passage
Results in
overheating, failure, huge repair bills.
overheating, failure, huge repair bills.
7
Injectors
Perfect synchronization
An engine's injectors really need to be in sync and produce the ideal spray pattern and pressure
Injectors create correct atomization of fuel into the power cylinder
Non-genuine injectors were found to be below specification in several areas
