PROBLEM
Show/hide table
| The connecting rod bearings may fail on certain CP56B, CS56B, CS66B, and CS68B Vibratory Compactors. Failure may result in abnormal engine noise from crankshaft/block area and loss of oil pressure. The engine oil needs to be a higher viscosity to offer enhanced protection to the connecting rod bearings at high loads. |
