| Special Sampling Considerations |
| Follow up on abnormal samples |
FILTER |
WearCheck advises that filter analysis be performed with resamples on equipment that tested abnormal. Filter analysis allows the diagnostician to locate and detect major wear situations. Filter analysis can be performed on any equipment that has a replaceable filter. |
|
| Extended oil drain interval testing |
MOB 2 |
Any equipment that is undergoing extended oil drain interval testing should use MOB 2 test kits. These kits include TAN testing (or TBN testing for engines) to monitor the degradation of the oil, as well as the build up of acids in the oil. Oils with high TAN levels (or low TBN levels) generally experience oil thickening, sludging, improper oil flow, and corrosion of components. |
|
| Samples for insurance/warranty claims |
INS |
The MOB 1 and MOB 2 kits are not meant for this purpose. The insurance (INS) test kit provides a complete analysis of the oil and filter. This allows WearCheck to assess the condition of the equipment, and of the fluid prior to the failure. A report is issued, specifically aimed towards validation or invalidation of a claim. |
|
| Large Diesel Engines |
MOB 3 |
WearCheck advises using MOB 3 kits for large engines (>100 litres of oil capacity). MOB 3 kits include the most comprehensive battery of tests to monitor the oil condition, wear condition, and contamination levels of the system. |
