Oh boy,,,,,,, NH 268 repairs

Hi!
I was not pleased with the puddle of oil on the ground underneath the baler.
It all started when we had a choice between a NH 65 and a NH 268, we chose the 65 because the 268 had a wobble in it's flywheel ('bout 1/4" front to back), and since this is my first year making hay, we thought the smaller baler would be easier for our tractor and ourselves.
BUT
When we went to bale with it, it would not tie right, I fussed with it, and got it to just hangup on the billhook, the knot would be %80 of the time good, IF I could stop the tractor in time to pry the knot loose. Mom went to go get the seller of the baler, while we kept working with a sick feeling. (you know, that sick feeling you get with a just bought baler) anyway before Mom got back the chain for the ..... the thingies that push the hay into the bale chamber, busted when the ..thingies.. were inside the bale chamber, the plunger moved forward and neatly stoped the operation with a crunch.
It was friday, and we got together with the seller on sunday, along with his friend Gary who knows alot more about balers than I do. We fixed the afore mentioned breakdown and tried to get it to tie right, but it just wouldn't. So the seller said he'd go and get the 268 and trade the 65 for the 268. He brought it to the field and the 268 baled without a hitch.
A couple weeks later (with rain and tempting sunshine and more rain) and 400+ 60lb bales later, I see this leak under the flywheel when I went to cover it up. The flywheel now can be moved back and forth which makes me think that not only will I need new seals but also a new bearing.
How hard will it be to do the repair? What problems should I look out for? What would your estimate be? And will the wobble in the flywheel make it come back real soon?
Looking at the diagram on the baler (though I don't know if it's intended for this purpose) it seems like the 90wt oil level should be below the shaft, and if so it shouldn't leak just sitting on level ground.
Any help would be appreciated.
Thanks in advance.

My 269 specifies that you use SAE 30 oil i the gear box. I have often questioned that spec though. I think the 268 and 269 are about the same.

The manual (dated 11-65) that I have for the 269 says #90wt in the gear case.

Hi!
Thanks for your replies!
We live in WV (If you got a map of WV and made a dot on the middle of the state you wouldn't be too far from our place), and the 65 baler - as far as I know- is out of my hands, I don't know what the seller would want for it now, but it's probably too long of a road trip to get here.
After we had seen the puddle of oil, my Dad had grabbed the flywheel and pulled it back and forth, BUT when I was checking it out I saw that the shear bolt didn't have the nut on it. So it would be nice if that was the only problem. I'll probably check it out later on today.
The wobble I had mentioned was when the baler was running, so I was concerned that it would wear the bearings faster, but I don't know how much of a wobble is too much.
I don't have a manual, yet. A friend that we'll be seeing in a couple of days has a manual, but if you could you tell me if the oil level plug is lower than the shaft, it would save me time, so I could get the parts in the mean time.
BTW our friend's baler dosen't have the level plug at all, he's looked where the manual shows but he can't find a thing. And he's an owner of a transmission shop! So there must have been a goof-up at the NH factory or something!
Thanks once again!

Is the shaft coming out of the gearbox wobbling? You have problems.

Does the shaft pull in & out (not wobble tho)? You might want to get it rebuilt before it wrecks - needs some washers now basically; if you wait it needs the $$$$ parts mentioned later....

With the shear pin out, does the flywheel wobble on the shaft? Some is normal, a lot means you need a new bushing between them - not a big deal, but you will have shear bolt & other issues without.

Get proper shear bolts, with locking nuts on them. A must have - regular nuts work loose (ever more so if there is any slop in the bushing) and only coause you headaches.

Don't run the baler without a nut on the shear bolt. Will bend the bolt, slop-out the holes the pin is in & from then on the bolt will not shear off smooth, it will bend before shearing. Can't get old one out; new ones won't be tight & more likely to shear....

Seeker,
1st, the oil level plug is not a plug at all but one of the back cover bolts. (this is another reason why a manual is an absolute must)
It is well below the bottom edge of the main input shaft.
2nd, I'm not sure that you really have wobble in the flywheel shaft. Because of the design and forces created by the flywheel and plunger these units have a tendency to wobble the entire unit.
I do think that u probably have a bad seal.
If you have shaft wobble that would mean that the gears in the gearbox are bad. These must be replaced as a matched set and the cost for the gears alone is in excess of a thousand dollars.
I don't know what your abilities are but, this should not be attempted by a novice mechanic. Good luck & let us know how you come out

No big deal if the flywheel moves back and forth. All that matters is does the input shaft have play in it? Steve

Well looks like you got some good answers to your question but what I want to know is where do you live because I would like to have that 65 baler that ya'll are having trouble with,I am here in east Texas maybe too far but I will keep looking. Thanks

While on your way to pick up that 65, swing by KY and I'll load up a NH Super 66 with PTO, with a broken wadboard chain, bent wadboard metal piece, cheap;-)

 shaft or flywheel moving?? in reply to Truth seeker, 07-30-2006 11:07:08  
You are going to have to find out if the flywheel is loose on the shaft or is the shaft actually loose in the front gear box bearing there.

The flywheel bore has a brass bushing in it that gets worn over time causing some play between the flywheel and shaft. Some play is no big deal.

However if your gear box input shaft is actually moving around causing oil to leak out of the gear box etc. then you have a more serious problem.

Seeker, a couple things.
First, I assume what you mean by wobble is that you can move the flywheel back and forth on the shaft that its mounted on. If this is the case some movement on this shaft is normal. If you have the shear bolt that passes through the flywheel tight it will probably take most of this movement out. If the shaft itself wobbles you've got problems you don't want to talk about.
Second, you need to determine if the leak is actually from the seal where the input shaft goes into the gear box. Check the oil level according to your manuals instruction because it may have been over filled. If so lave the plug out on level ground and let it drain down to the correct level. If this is not the case and you need to replace the seal I think you can just remove the 3 bolts in the slip clutch, remove the flywheel and the casting at the front of the gearbox to get to the seal. Be extremely careful when removing the flywheel or you may loose some toes. Use a loader or hoist. The same when re-installing.
I may have missed something here which I hope others will point out. Good luck..... .
