Help setting up MF12 baler

As I've mentioned earlier, I've got a MF12 baler. My son and I are planning to make hay this summer. Where does the time go? My son has been working on a PT10 haybine. We've got it turning and it will need a few parts.

My job has been this baler. I've been as busy this spring as a one armed paper hanger. Since we are just a couple of weeks (at most) away from decent baling weather, I guess I better get cracking on it.

I dowsed every part that I could find with a liberal coating of hy-trans oil, as OLD suggested. I left the tying mechanisms alone for now. I just can't get the plunger to budge.

I couldn't get into the baling chamber myself, so I sent my son, whose shoulders aren't as wide. He got most of the crud out and we shot a lot of oil around the edges. But we still can't get the plunger to budge.

So, here's the question. Do I need to disconnect the wear plates or anything else in order to get it to start moving initially? My guess is that the wear plates are stuck to the tracks along the sides. I just don't have a clue right now about how to get them moving. We've tried tapping along the outside with hammers to try to pop it loose. I would try heating it, if it were not for all the oil in there now.

Any advice on this one would be greatly appreciated.

Yesterday, I got a long 5x5, a sledge hammer, and pretended to be 22 again. Then over the course of the afternoon I beat the blank out of it. I got it to move! Got the plunger all the way to the fully retracted position and then was able to use the flywheel to crank it. I got it from the fully retracted position to about 2" beyond the original starting point (which I had marked), a distance on the baler of about 6". It was at this point that it got bound up again and wouldn't turn with the flywheel. This evening when it gets a little cooler I'm going to hook up a comealong and start at it again. It was encouraging to get it to move.

Another question now. I loosened the bolts on the side and also those on top and bottom of the bale chamber. Is there anything special which needs to be done when tightening them again?

By the way, I only pretended to be 22 again. This morning I discovered that I wasn't. My oldest son is almost 12. I can barely wait until he is 16.

Thank you all for your advice and encouragement. I'll keep you posted.

Christopher

I went through this (and still am) with my #3 - same baler except smaller. There are adjustment shims inside the chamber - they run along the top where those adjustment bolts stick out. When this shims rust, they get fatter. I had to use a hammer much larger than 20 pounds, and also put a HiLift jack in front of the plunger to move it towards the rear. You have to reinforce the front of the baler when you do that or else you'll bend the metal. I've used penetrating oil, grease, 90 weight oil, and I don't know what all to get mine free. Yours will be in better shape - mine sat out for nearly 40 years without turning over. I did get a good deal on it . . . .

try a come-a-long to get it tight and then hit her hard. with the top and bottom adj. bolts loose,(3--1/2" on the top and 5--1/2" on the very bottom) it should have moved..the 3/4" bolts on the side are to push it in and draw it out only.

Chris, I had the exact same thing last year with a number 10 baler, I am going to give you the straight poop! Eat your wheaties, get as many of your sons buddies as you can muster up, find a long hedge post that will protrude from the plunger out past the end of the baler and a 20 lb. sledge hammer , do you see where this is going? I also had a come along on the crank fastened to the front of the baler, and had it tight. I did everything that you have done and probably more, but it will take the force and the vibration to break it loose, once it moves you are practicly home free, mine was so bad the neighbor, said I should scrap it! After I got it loose it worked like a million dollars. I suggest if you do not have one, to get a manual so you can set the chamber back to specs. Do not be afraid to beat hell out of that plunger cause thats what its going to take to free it! Let us know how you come out. The baler is a good baler!

Does the # 12 have the adjusting bolts/with locknuts on the side of the chamber ? If so loosen these off top and bottom and you should get er' movin'. You will find it thick with rust between the runners and the chamber.

Thank you for the advice. I loosened the adjusting bolts, even took them completely out. A whole bunch of rust at the end of them. Still could not get the plunger moving. I unbolted the arm going to the plunger and used a 5x5 block to try to get it loosened. It wouldn't even wiggle.

Unless anyone knows another trick, it looks like I am going to strip the bale chamber down to break it loose. This baler sat for the better part of a decade in a shed before I bought it at an auction.

Now a new question comes up.... How hard are these machines to put back into time. I imagine that if all I mess with is the plunger, it should not be too hard.

I wonder how much fun I might have with the knotters.....

Sorry should have mentioned....you also have to loosen the nuts on the bolts top and bottom of the chamber to allow the runners to slide away from the plunger, you will see they are in elongated holes.

I don't think heat on the chamber is a good idea just yet, might warp something. You probably have the chamber body then a track or rail that the plunger rides on. The heat transfer would not be very efficient. Can you use a long steel shaft(like1"-2" dia.) and try to knock the plunger back and forth. Is the bull gear actually trtying to move the plunger or is your problem in the gear box?

The shaft out of the gear box is trying to move, it twitches a little in either direction. The shaft going to the plunger is also moving slightly, but the plunger will not move at all, not even a fraction of an inch.

There is the chamber body, a track and then a wear plate between the track and the plunger. I'm worried that I might have to strip the thing apart if I can't find an easier way to get the job done.

I have tried whacking the plunger with a 5x5 on the outlet side, and with a 2x4 on the driveshaft side. The plunger is within about 2" of the fully retracted stage of the cycle.

In addition to oiling it, this afternoon we used a hose to spray out all the remaining crud and getting under the plunger. I need to go back out and use some more oil in place of that which I sprayed off.

Thanks for the help.

Christopher
