Re: Front crank seal leak

Contact Rob at NeedsWings, I'm sure he will do whatever he can to remedy the situation.
NOTE: Some seals do not have the spring ( they rely on pressure difference to keep the seal against the shaft ), but most do.
Some pics of oil seals to show some of the variety of designs out there.
All seals leak a little, the leakage lubricates the friction face and keeps the seal working.
As you can see some have the spring on the lip and some do not.
A big name in seals is/was Chicago Rawhide, guess what they used in some of their seals.
They are now owned by the bearing company SKF.
