McCanna, ND | I asked the case mechanic about this last winter while we were going over my 120 series. He doesn't recall ever doing a set on the self leveling sieves. Unless they are knocking or in tough shape I wouldn't worry about it to much.
It seems like the bearings on the connecting rod that drives the sieves go out more often. Have heard of some going at 1500 hours. Also check the roller at the back right corner of the sieve frame. They wear flat spots in them and will give an appearance of having major issues | |
