    Rotary Valve and Intake

    Okay I've got a tech question on the condition of my rotary valve and intake. Evidently the engine spun a bearing on the connecting rod and sent the needle bearings throughout the motor. When I pulled off the rotary valve cover and plate I noticed some deep gouges in the intake port on the case as well as the intake side as well. I need to know how I should proceed. I was told that a welder could make the repair but that sounds like a bandaid approach. I'm thinkng just to send it in to SBT and hopefully have an exchange motor sent out. Also I need a question ansewered on the drive shaft. When I pulled the drive shaft from the pump I saw this rubber seal in the end of the pump side. It looks as if it was installed wring becuase of the condition. (see Pics) I can't find this part anywhere in my manual. If someone can identify or possibly knows the part number it would be greatly appreciated. I noticed large amount of sand inside the pump housing and shafts stuffing box when the shaft was removed. Please view pics and let me know your thoughts.
