391560305 / C / 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. Resample after repairs or adjustments. ** For enquiries regarding this evaluation, please contact Katrina Holmes Ph 08 9377 9563. Sample Note :
391211501 / C / The oil viscosity (V40) is lower than the specification for the reported oil. This may indicate mixed oil brand, type or grades or possible oil transferring between compartments. The fine iron is high. The PQ index is slightly high. Check the magnetic plug for excessive ferrous metal. The silicon may be leaching from the duo-cone o''ring seal. For enquiries regarding this evaluation, please contact Jim Durning Ph 08 9377 9757. Sample Note :
390921542 / C / For the reported oil hours, The fine iron and the PQ index are increasing. This oil sample appears to be dark. 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 :
390571415 / C / PQ index, iron and silicon are still 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. All other test results appear to be within acceptable limits. Continue to sample at recommended interval. ** For enquiries regarding this evaluation, please contact Katrina Holmes Ph 9377 9563.
