changing knives on promark 210

[allen t]

Hello I am trying to change the blades on a promark 210. I havr removed the locknuts on the back of the disk but I can not get the countersunk bolts on the knife side to budge. Are the bolt holes threaded and have to be screwed out or should you be able to knock them out? I would appriciate any wisdom from those who could help. Thank You

I understand the bolts are threaded also. I can not got the bolts to budge out of there holes . I was wondering if the disc holes that the knives mount to are threaded also ?

The disc does have threades in it for the bolt to screw into, the the lock nut is put on for extra safty. I have not done many of the promark knife jobs but every one I have done has been hard to get the bolts out. I am sure some one who has done a lot of these will post a easy method. In short the bolt has to screw out of the disc. Good luck.
