When rebuilding an engine check carefully the two essential pumps, coolant and oil. The finest built engines cannot survive pump failure, and after such an investment of time and money, going the extra mile to ensure that both of these essential assemblies are working to full capacity, with, if required the various wear prone components replaced, would be time and money well spent.
Oil and coolant, at the correct flow levels, are the two essential elements an engine requires. Add as many parts as you wish to the same shopping cart, new seals 9310911073 9310212321 bearings 9330600105 and dowel pins 9360316219 9953010114 for example, and still only pay the same single fixed price shipping cost. This component may have other applications within the Yamaha model range.
