hobbyfarm Posted May 22 Share Posted May 22 Had a bearing go out on the discbine conditioner. It was a fight but I got it done. I applaud you guys that does this every day. I'm sure you learn tricks after awhile but still some things aren't easy. A combination of heating it dull red hot and a gear puller got it done. Harder then it looks for an amateur. 7 Quote Link to comment Share on other sites More sharing options...
brahamfireman Posted May 22 Share Posted May 22 Tips and tricks. Usually with a bearing that far gone you can remove everything but the inner race on the shaft. If there's not much of a fire danger you can torch off the inner race by blowing the slag at a 90 degree angle to the shaft. If you go slow, but quick you'll never even knick the shaft. Only need to torch off the "top", the heat will expand the remaining race parts and you can slide it right off. 3 Quote Link to comment Share on other sites More sharing options...

I'm not sure of the lineage but very much the same as Hesston. Zimmermans sold me an agco packaged bearing. Hope to keep this thing going a few more years. Im guessing it has a lot of acres through it. I've had it about 3 years. Quote Link to comment Share on other sites More sharing options...

My torch time is limited. I was kind of scared that if I mess up that piece of shaft I am trouble. Right or wrong cleaned things up with fine sand paper so the new would go on.

A little sleeve retainer always gives added confidence. Quote Link to comment Share on other sites More sharing options...

Picture of the back would confirm my thoughts 2 Quote Link to comment Share on other sites More sharing options...

Picture of the back would confirm my thoughts I just researched it, you are correct. Heston built this unit. The similarities to a New Holland 1431 is why I thought it was their design.

Our main problems were they were well used and the conditioner bearings were an issue because the rolls were out of balance from too many rocks through it. The assist roller was the worst for beat up Quote Link to comment Share on other sites More sharing options...

NH has solid sides. I prefer the NH shielding and the Heston drivetrain and cutterbar 1 Quote Link to comment Share on other sites More sharing options...
