The last couple of seasons my board racks became harder and harder to swivel. I decided this off season I would investigate why. After finding only a small amount of information on the one year only board rack design, I thought I would share my findings and repairs I had to do.
The original design is flawed. The top of the board rack has 4 bolts that hold the cam to the arm, however the bottom of the board rack is connected with only 2 bolts to the other end of the cam. You will see in the pictures the bolts were badly bent and stressed ready to break off completely. The ball bearings and SS plates were badly worn also.
I replaced the two top SS plates that the ball bearing ride on and all 8 ball bearings. Also replaced the bottom cap that has the threaded knob that tightens down to lock the racks from swiveling. The cap bolt holes were worn and enlarged from the design flaws.
