Replacing Disc Bearing

WNYBill · Feb 14, 2023

The disc axel is 1 3/4 (70mm), There is a bushing on the axel that is 2 3/16, the curved top bearing goes over the bushing and into a flange/casting. What hold is all together? Is there a trick to getting it all together? Thankfully it is the end bearing and I only have to remove 2 disc blades. It is a Hutch Master Offset Disc.

The big nut on the end of the disc shaft holds it all together, not sure what else you might mean by that question. Put it all together and tighten it standing on the end of a 4 foot cheater pipe on your wrench. Use it a couple hours and check it for being tight. Continue checking it periodically until it stays tight.

Now that I have everything apart, I see that is exactly how it works. My only experience was a light 6 foot 3 point disc that used a sealed bearing the bolted on.

redMN, There are 3 supports with bearings and bushings on the axel. I am hesitant driving the axel through the support to replace the broken discs and bearing. I am afraid I may not be able to drive it back through the 2 bearings and bushings. However, I am having trouble getting the support off the frame. What do you think?

Sorry, did not see your reply that is the curse of Classic View. There is a possibility that you have it all done. Do not get me wrong my experience with this type of repair is from way back when I was 20 or younger and I am 60 now and the disc was much smaller. In my opinion if the shaft drives out it will probably drive back in. Depending how clean you have it granted a lot of crud may get down in there and hinder the initial tightening. But that is taken care of by the repeated tightening checks. As far as removing the support without pictures I would have a hard time helping you.
