Put on your thinking caps. Oil leaking

[MG2936]

SKF 49927 There is much information on it on the SKF web site. A standard Nitrile seal is good for a temp of 250 degrees, the seal temp will run 30 degrees hotter then the engine temp because of friction. If your deuce is running 200 on a hot day, you are pushing the seal close to the max. The 49927 seal is good for 400 degrees. It is also twice the cost of a standard M35 seal.

Thank you to all the guys who suggested my problem may have been bad seals. It got me thinking and sure enough there are today better seals than what was designed for the M35 back in the 1960s. I installed what you might call a premium seal and the truck hasen't leaked a drop. I'm on the road again!

If the new seal is significantly better and holds up longer, the additional cost is insignificant.
