It was leaking because it was bad, direction had nothing to do with it.chiro972 said:...Mine was leaking but the bearing feels fine and I thought maybe the reason it was leaking was that it was installed backwards...

That's not entirely true. Yes, increased pressure on the open side will provide greater sealing ability, but a seal will work perfectly fine in neutral pressure. The garter spring provides enough pressure on the lip to maintain an effective seal in the absence of external pressure.76GMC1500 said:I say the open side goes towards the pressure, not the fluid.

griffbones said:I know for a fact that the right side crank seal goes with the open side towards the tranny oil. Besides the crankcase alternates between pressure and vacuum. Show me a manual transmission that has the open side of the lip seal outward on either the input shaft or output shaft! How about an axel seal, a primary drive or tranny seal on a H-D, how about the pinion seal on the rear end of your truck, do I need to go on?
I am fairly certain all your bikes have the seal open to the crank,when applicable! So either there is confusion,or you are the perpetrator of misinformation and backwards seals! That 76 rm125 is THEE only one I have ever seen,and it was double lipped and the right bearing got lube from the tranny! http://houseofmotorcycles.bikebandi...wSchematic.aspx?deptId=1130318&machineId=3774griffbones said:I know for a fact that the right side crank seal goes with the open side towards the tranny oil.
