just a tish NE of central ND | Here is my take on it....... it is the same as about most any broken shaker system. Something is loose and banging around. You clearly have bushings that are shot so throw them all away and start fresh. EVERY single one of them should be replaced. Bearings need be tight as well as sieve parts to stop the banging of stuff. Your ratchet clutch under that pulley can also wear in the mounting holes and bang as the shaft rotates.
As far as alignment, it is aligned on a hex shaft with a half moon key. if the key. If that goes in the shot properly you cant have it out of time on the shaft. It needs to be centered in its stroke (centered in the slots and then tighten the bushings down tight) as to keep bushings from twisting too far to one side or the other, its very important to get that at least close to centered in the slot. Over twisting will destroy them. |
