2nd project on the 535 round baler. This is the culprit that caught the baler on fire last season. The lower roller bearing came apart.so i am replacing bearings on both sides. This is my problem i cant get the locking collar pin to come out. Any idea's? I bought new punch that is the correct size and i have beat the crap out of this thing and it hasnt budged a bit. Any help would be appreciated! Thanks in advanced for any help!
