I need some help removing plunger bearings on a new Holland 268 baler. Any tips tricks or sage advice appreciated , thanks.

I have a 271, but plunger bearing removal is probably similar. Disconnect plunger rod at front of bale case, move plunger to rear of bale case. It will be obvious how to remove bearings after you get it at the end of bale case. If it is like mine, the bearing is held by a large threaded rod with hex or square head on end with a large nut that goes on the threaded portion. these two are used to adjust the bearing clearance. Take note of the adjustments before removing and try to reinstall bearings to the same adjustment. Get a manual.

A NH dealer told me back in the day that the 268 was lightly built. Therefore, pay attention to the wear in the bottom of the bale case as you may need to weld plates in there to allow for wear. My 271 has that problem. Also, the hinged plates that are at the top and bottom of the case and are moved up or down to change bale tightness may be worn or rusted and need welding up.

Good luck.

thanks for the reply. I should have been a little more clear though I already have the plunger out my problem is that I cannot get the bearings loose. they are held on with allen head bolts and I have already broken 3 hex head sockets trying to loosen them ,just wondering if there were any tricks I should be aware of. also I do have a manual that's what got me into this mess lol I was adjusting all the bearing clearances and plunger knife when I realized I had a bad bearing.

Recip. saw or blue wrench. New bolts and nuts.

no luck there either bolts are threaded in to shaft no nuts.

Try a 3/4 inch impact driver with black socket.

Weld a bolt onto the allen head, the head will bust the rust seal.

It takes a 3/16 hex bit socket or allen head, I should have worded that better in previous post. I ended up cutting the bearing race with a cut-off wheel worked great as soon as the pressure was off the inner race the allen set screw came right out. I heated that thing cherry red with the torch thinking it may have had lock-tite even or simply rusted but it would not budge until pressure was released from that inner race. thank you for the advice.
