Appart from the initial lubrication, the grove on the shaft would affect 
the life of the seal and should be smoothened out by using fine abrasive 
paper (600, 800 +) and only radial turning motion. If the groove is to 
deep, the seal should be inserted to different depth to avoid the 
groove. If that isn't possible, then the seal spring could be tightened.

HTH,
