I have just fitted the metal type clutch side oil seal after putting in a new main bearing.
I was careful only to tap down round the edges of the metal to get it into place so as not to damage the inner area.
However, now its in it seems to be very tight against the bearing. I can not turn the bearing now using my fingers, with the crank pushed in slightly it will turn but is very stiff.
Is this normal when fitting a new one of these seals ?
