The most important mechanical assembly in the engine; if this is not right the engine will be sub-standard, with unpleasant vibration and a lack of real performance.
Renewing as many of the wear prone parts that make up the complete crank-con-rod-piston assembly as possible can only be beneficial.
This component and perhaps some of those listed below may be required:
Add as many items as you wish to the same shopping cart, new con-rod bolts 3LD1165400 and piston pin circlips 9345022027 for example, (as the old ones should not be reused) and still only pay just one single fixed price shipping cost.
Don't forget to order all the gaskets and seals required to complete the assembly of the engine - try this pro-workshop gasket sealant 08CRAHLG120G to complete the job like a professional.
