Yep, I put that kit on last winter too. I also like to put in a new shaker shaft and left cam whenever I find any slack on the left cam. It helps reduce the stress on the entire shaker system by keeping both sides in perfect time with each other. The other thing to do to increase the lifespan of the bushings is to move the shaker to the neutral position every time you shut down. Especially if the machine will be sitting for a while.
