Easy Way to Find a Leak
|
|
|
|
Suction line leaks can cause air entrainment and problems such as excessive aeration, air lock, pump cavitation, poor lubrication and premature oil degradation. While a pinhole-sized suction line leak can be hard to find, using a small amount of shaving foam sprayed over the suspected leak area can indicate the source of the problem, as the foam is drawn into the line. This method should not be used for large leaks, and care should be taken not to use too much soap, since this can cause contamination of the lube, resulting in foaming and aeration problems and poor demulsibility.

Identifying Grease Contaminants
|
|
|
From the "Wear Particle Atlas":
Large, abrasive particles in grease may be more damaging than the same particles in oil because once the grease is applied, no opportunity exists for the contaminant particles to be removed; whereas in oil, the particles may be quickly removed by filtering. The particles in a grease sample may be scrutinized by dissolving the grease with a suitable solvent and then preparing a ferrogram. A mixture of toluene and hexane is effective at dissolving many commonly available greases.
