Listed here is a NEW ZF Hurth transmission shaft seal.  This is a Genuine OEM ZF part NOT a cheap Chinese aftermarket replacement.  The part number for this seal is 0634319133 or sometimes just 634319133 and lists for about $50 new from the dealer.  According to the internet this replaces the old Hurth part number 444070 (since ZF owns Hurth) and Mercury/Mercruiser 26-811956 since they used the ZF/Hurth trannys on their platforms as well.  Please verify this since I have no way to confirm for sure.  This seal has an outside diameter of 11cm but is listed as 110mm.  The letters TC 85 110 13 and NOK are printed on the seal.  Seal does not come with original packaging.   I had two of these and the other sold along with the package.  Picture shows old wrapper to show it is an OEM seal.  Shows no sign of wear, corrosion, or dry rot.  Measurements are shown so you can confirm fitment.  Purchased from ski boat dealer inventory buy out and I have no way to confirm fitment.  The seal you see pictured is the actual seal you will receive with nothing extra.  Seal is stored in a climate controlled parts room to prevent deterioration.  If you have any questions please feel free to contact me before purchasing and I will help you to the best of my abilities.  Thank you for your interest.  Steve MMSLLC :)
