Plunger pin on JD 24 T

draftx · Apr 5, 2016

Trying to get the plunger pin out to put new bushings on it. Anyone ever removed one before. I have a punch thru the side of the chamber trying to drive it out but its not budging. Trying not to pull the whole plunger out the back if I can help it.

With the retaining bolt removed can you rotate (a fraction of a turn) the pin while adding TIME and "loosen juice"?

If I was attempting to replace pitman bushings in PH I'd elect to remove PH from baler as that task only takes 5 to maybe 10 minutes. If pin is that difficult to remove baler operator must have been overlooking regular greasing of the grease fitting or grease fitting is plugged.

On my New Holland 68, I pulled the plunger and replaced the pitman bushing. The original was brass, the new one is some kind of steel.

To get the bushing out, I used a hacksaw blade and cut a groove down the axis of the bushing such that it would collapse inward just enough to fall out. There were two bushings - one on each side of the plunger. A friend of mine pressed in the new bushings - cant remember the tonnage, but it groaned putting in the bushings.

Once done - I was AMAZED at how tight the pitman was. The old 68 is a noisy baler in the first place, but there is no more plunger slap from the pitman anymore.

Pull the plunger, free-up and sharpen the knife and do any other maintenance you may need while it's out.

24T - IMHO is a very good baler. I worked behind one years ago stacking on a wagon. Can't say I ever saw it mis-tie a bale. The most impressive thing was the absolute bricks it would crank out - all day long.

Good luck,
Bill

Bill,
How tight was it? I just got mine (NH 68) back together (new bushings and pin) and can rotate the connecting arm (pitman) back and forth on the pin but barely. It is very tight. Am a little nervous about putting it back together this tight.
Did you just go for it and let it wear in?
Thanks,
Mark

I ran one for real the first time last week. Took a little bit to get everything tuned in and all the pieces polished up but it hasn't missed a single bale in 400+ probably closer to 450. Bales stack like Legos.
