Good day to all. I am in the process of replacing water pump seals on a 2005 KLR650. Fred's parts arrived quickly ... thanks Fred for your service to our community. I installed the oil seal with the closed portion facing out as per the manual. When I look at the seal from inside the case cover, it appears that the seal needs be be pushed about a millimeter or so to seat, but I can't get it to go any further. Is there supposed to be a small channel between the "shoulder" of the opening and the seal? In other words, does the seal seat higher up in the hole with some space left over? Thanks for any information. Kevin
