This ensures that wear products and lubricaing oil contaminants are thoroughly mixed with the lubricant and that the heavier wear particles have not settled out.
Once a proper sampling point and method is chosen for a particular component, oil samples from that component should always be taken from the same point with the same method. The following sampling points are recommended:
