I've got my knotter drive sprocket off my NH68 baler and also the pitman arm for the plunger. I'm replacing the bushings in both. Both of these have brass or bronze bushings at either end of the part where the shaft they ride-on goes through - so to bushings at opposite end.
I'm trying to figure out how to get these bushings out! I suppose with the knotter drive sprocket, I could drive both bushings out in the same direction and replace from either end. However, the plunger pitman arm, the tube those bushings are in is about 5 or 6 inches long. The bushings are at least 2 inches in length themselves. I think it would be difficult to drive them out in the same direction - but I suppose I could do so if necessary.
What I'm thinking is using a brass punch and going to the inside shoulder of each bushing and trying to tap them out. Not sure if this will work.
Any suggestions? Worse case, I can take them to a machine shop.
BTW - the New Holland replacement bushings are steel. I guess this is OK, but I'm concerned about the potential for galling or which is harder, the shaft the part rides-on or the bushing itself - seems to me something needs to be sacrificial, especially with a bushing. I like the brass/bronze bushings - not sure why the change to steel. Sounds like a bigger can of worms to repair down the road than a softer material like brass/bronze. Who knows - maybe by then, the industry will have come out with a superior baler to the New Holland 68 and I'll just make a change..... ;-)
Any tips or tricks are much appreciated.
Thanks!
Bill
