---Depending on how many links I have in the chain, I can't move the shaft far enough forward for the cams to sit correctly in the crook of the bars. Not sure why this is happening. The coupler is at the top of the A-frame so nothing unusual there. I may try moving the cam arm brackets forward slightly and I don't think there should be a problem with this.
The position of the frame plate depends on the depth of the frame rail. The 19 3/8" assumes a 6" depth.
The position of the frame plate also depends on the elevation of the rear end of the WD bar (determined by number of links under tension) when adjusted for normal use.
If the rear end of the bar is raised, the cam support arm needs to be shorter.
If the rear end is lowered, the arm needs to be longer.
The instructions state:
"The Measurements in figures 6, 6A, 7 & 7A are guidelines, adjustment of the cam arm length via the adjustment nut (Figure 5)
may be required after hookup in later instructions of this manual."
