Help changing outside coolant pump seal

Hey guys, can someone show me a pic of the outter waterpump seal on their wr, I have an 06 450 and changed the outter seal, the stock one, from what i can remember, came out with the flat side facing me, but the book says to put the words/numbers on the seal facing inward, i done it that way and the bike immidiately filled up the oil level with coolant, not good. Others on other forums say i put it in the correct way, but I don't think I did, obviously. can someone help me out here please....

hey mountainmax,

I do not have any pics of the seal, but I can 100% confirm that you put it in the wrong way if the flat side with numbers was facing you.

Flat side and numbers need to be facing inward, so you will be looking at the 'back' of the seal once installed.
