My K100 has had a small oil leak from the seal behind the water pump for as long as I have had it (about 20000ks) but lately it has been getting worse. So I decided to change the seals. Ordered a kit from Motobins. Took it all apart no worries. Followed the instructions that came with the seal set when refitting. No oil leak now, but it pisses coolant out at an alarming rate. Obviously I've damaged the water seal , so I'll have to start again. No oil leak though
I have 2 questions,
firstly, what is the best way to get the old seal out. I resorted to butchery with a screwdriver and a hammer first time, but maybe there is a better way??
and more importantly, what is the best way to put the new water seal in. I tried the "draw it in with the bolt" method recommended by motobins. This didn't work. My manual recommends using a large socket and carefully tapping it in. My thoughts are that the socket method is better because it doesn't put pressure on the centre part of the seal but I'm open to suggestions.
