FNG,the band is adjustable 2 ways, small screw with spring and j-bolt tension. try to get the t-case & trans alignment as perfect to 100% alignment as possible. you just have to play with it untill you get it. you,ll be glad you did down the road promiss . nice work your buildin a 1st class rig. glad to see it. also take the drum mounted to the yoke to your machineist and have him spin it on a lathe to turn the drum perfectly aligned and smooth. bet that is where your friction problem is. call if you need to.
