Lab No / Eval / Comment
391560306 / B / The oil viscosity (V40) is lower than the specification for the reported oil, possibly mixed oils, oil transferring or incorrect oil type/grade reported. Iron is increasing.Check magnetic plug for abnormal ferrous material, if not already done.The silicon may be leaching from the duo-cone o''ring seal.Check wheel bearing deflection is within specifications.All other test results appear to be acceptable. Continue to sample at recommended interval. ** For enquiries regarding this evaluation, please contact Katrina Holmes Ph 08 9377 9563. Sample Note :
391240811 / B / The iron concentration is slightly high, but rate is improving.Check the magnetic plug for excessive ferrous metal.The silicon may be additive/grease/compound related.The oil viscosity (V40) and add-pack do not match the reported oil, please confirm oil in use in compartment. All other test results appear normal. For enquiries regarding this evaluation, please contact Ross Gilmore Ph 08 9377 9506. Sample Note :
390921540 / C / For the reported oil hours,The fine iron and the PQ index are increasing.Check the magnetic plug for excessive ferrous metal.The silicon may be additive/grease/oil seal compound related. The oil viscosity (V40) is lower than the specification for the reported oil.This may indicate mixed oil brand, type or grades.For enquiries regarding this evaluation, please contact Ross Gilmore Ph 08 9377 9506. Sample Note :
390571416 / C / Iron is slightly elevated.Check magnetic plug for abnormal ferrous material, if not already done.The silicon may be leaching from the duo-cone o''ring seal.Check wheel bearing deflection is within specifications.The oil viscosity (V40) is lower than the specification for the reported oil, possibly mixed oils or incorrect oil type grade reported.** For enquiries regarding this evaluation, please contact Katrina Holmes Ph 9377 9563
