Heh, heh, okay, my only excuse for mispelling yoke is I type faster than my brain thinks. And my brain is mostly scrambled. In regards to your question, Jerry, the sleeve only covers the area of the yokes seal surface that the seal rides on. For example, if the cylindrical seal surface of the yolk in 2" in length, the sleeve only covers the bottom 1/2" of the cylinder where the seal rides. In regards to this condition, I think the sleeve manufacturers have thought this out pretty well.
