FELT DONUT BEHIND THE STEEL CRANK BALANCER

I agree that the slant 6 (and the older flat heads) were used in all sorts of non-automotive equipment. I've just never seen a small block in one. I guess I didn't hang around farm equipment much in my earlier years. I still doubt they would engineer, produce, and use a felt seal in every application for the few that would be used on a farm......and that's assuming what that one guy mentioned about Case tractors is true. My point is that with the modern seal, the felt seal does nothing but rub on the timing cover and seal. None of the other engines use them, so, why just the small blocks? I've never seen anything get wrapped around the balancer up in that area either. It's so protected by the balancer hub and the metal ring that I just can't imagine that being a problem. Maybe I've just been lucky to have never seen an issue with that. :thankyou:
