One big advantage of a clamp-style flailer is that it can be put on and taken off the crusher without having to remove the motor or bearings.  I expect that it will be much simpler and faster.

  • Installation method

    A 5/8” diameter flailer shaft should be installed in the crusher.  This will require the old 1/2”  bearing on the front of the crusher to be removed.  The front hole in the crusher then needs to be drilled out from 1/2” to 5/8” and a 5/8” shaft put in with a 5/8” mounted ball bearing.  Once the shaft with the coupling on the back is positioned correctly so that it mates with the motor coupling half with the motor bolted in place, the set screws on both bearings, front and back, may now be tightened.  The motor could be turned on briefly to break in the holes in the crusher where the 5/8” shaft passes through the front and back of the crusher’s body.

     

    • Make sure the 5/8” flailer shaft that can be seen inside the crushing chamber is clean.
    • Take the  socket-head camp screws out of the flailer.
    • On the flailer half that has the female-threaded holes at both ends for the cap screws clean the inside of the collars and put one drop of superglue on the inside arch of each of the end collars
    • Position this flailer half on the under side of the 5/8 flailer shaft equal distance from the insides of the crusher chamber (heads of bolts holding bearings are all tightened flush to the inside walls)
    • Hold this flailer half in place until the superglue sets strong enough to hold the flailer half in place
    • Position the crusher upside down with the bottom of the crusher facing upwards
    • Rotate the flailer shaft until the flails hang straight down and you can see the cap-screw holes in the collars
    • Take 4 each 1/8” x 8” straight rods and gently place one in every screw hole in the collar (these will act as guides for the second half of the flailer)
    • Slide the second half of the flailer down the guide rods until it rests on the super-glued half.
    • Remove one of the rods and, with a long arm 5/32 allen wrench with a small piece of gum on the end holding a cap-head screw, lower the cap screw into the hole and screw the cap screw in at least two turns
    • Repeat this cap screw insertion procedure for the other holes
    • Screw all the cap screws in until they almost start to tighten down. Tighten all the screws evenly in a criss cross pattern  leaving around a 1/16” gap between each joint of the collars.  Coat internal threads of female half of flailer with anti-seize lubricant along with the socket head screws before mounting to flailer shaft.  When tightening the socket head screws,turn each in it’s turn by a quarter or half turn.  If there is any chatter immediately remove socket head screw and reapply more anti-seize lubricant and start over. When the spacing looks right, do the final tightening on each cap screw as hard as you can turn the hex wrench without permanently twisting it.
