on the right hand the genuine part |
The fake has no seal to prevent dirty and filtered oil blending.
 |
A Seal and a fitting bypass guarantee reliable filtration with the John Deere filter.
 |
Lower spring pressure, lower spring displacement and an unspecific configuration of the spring provide a worse filtration.
 |
The genuine part has a specific John Deere spring and spring pressure.
 |
Inferior paper is more permeable to light and particles.
 |
High quality filter paper has a density, which lets no light through. This is genuine John Deere.
 |
The paper of the fake filter is not crimped folds can pool together. The subsequent filtration will be very unequal.
 |
If you press the paper you see that John Deere uses premium paper. It is pressed 150% more than the fake. This results in a stronger paper that is crimped
to support equal filtration and a higher surface.
