I am still on my original units. The ones I removed when I first rebuilt it and re-installed them. Basically, I did what they tell you not to do lol. Not sure what you are doing to them that is making them fail, but it might be a good idea to figure that out first.
You mean the seals you would have just replaced due to the fact that you just finished re-doing and balancing your crank rod and just put it all back together type seals???
EDIT...Guess that wasn't the crank then, you posted that just a second before I did...lol.
