Hi,
I have had this haybine for two season and it has worked really nice, until this seasons end. There is a clunking/pounding noise. I put the PTO in very low RPM just to locate noise, and it sounds like the rollers are the clunking noise and there seems to be more play in the upper roller compared to the lower. Does anyone have an Idea or know what has happened. Also, are there any good/complete service manuals out there for this machine? Appreciate any advise from you experts out there!
Thanks
Bill

i purchased a 479 this summer and it sounded like the rollers were clunking, i did alot of digging into it and found the bearings were out on the wobble box for the sickle, it is amazing how sounds can travel, this may not be your problem, but just an idea, john

Bill, there have been some good suggestions here for you, but I suspect the noise you hear is coming from something else. First off, your haybine does not have gib keys, so loose sprockets are not the problem. The wobble box is certainly something to check. However, I suspect the source of the "clunking" is at the top roll rear pivot point. Let me try to explain what I mean, but I don't know if I can. As I'm sure you know, the top roll must open and close everytime a slug of hay goes thru it. That pivot point that the top roll pivots on is a 5/8" carriage bolt with 2 different bushings. It is not uncommon for one or both of those bushings(or spacers) to break and actually disappear. If the 2 rolls are close enough to tip each other, the top roll pivot point "clunks" very loudly. I hope this makes sense. Also, is there any rubber coming loose from either roll? This too will clunk. Also check the rear end of the tongue. If the hanger in there is sprung down, the pto inside the tongue will start banging on the tongue pivot pin or bolt. Hate to say it, but the 489's were the quietest machine when new, but the most noisey machine when old. Steve

Once again everyone, Thanks for all the info! I'll tell you, this has been a very good discussion board, learned alot!

Steve, to answer your question. All the roller rubber is very good! I will be looking at everything! Not too sure I understand the tongue hanger springing? I have noticed the tongue isn't level coming out of the housing, it tilts towards the machine. Is the hanger repairable or a replacement part? What's the deal with straightening it? I'll tell you this machine has been very quiet and smooth cutting and running until two weeks ago. My wife couldn't even here it running from the house, unlike my neighbors haybine, which is way farther from our house and sounds like a 7th grade marching band without sheetwork coming up the road!
Bill
Thanks again!

Bill;Disconnect your knife and wiggle the arm that drives it(the knife). If there is any movement in that arm your wobble box might be shot.I have one of the oldest 489's around and it is on it's third gear box, about 650 dollars plus labor.

Bill, if you haven't checked the bushing on the cutter bar, you probably should; very commmon cause of clunking on these machines.

i had the same sorta sound on my haybine a while back. it turned out that when my haybine had been parked some kids played with the cranks for adjusting the pressure on the rollers, they had backed one off so far that it was able to clank up and down about 2 inches, i just readjusted it and was good to go.

Check the sprokets on the end of the rolls to make sure the keys are still in them. Had the problem on 2 different 495's of the keys comming out.

Thanks Jimmy,
I will inspect that! I did notice there were either roll pins or keys as I was going back and forth by hand.

My 495 had tapered keys with a tab on the big end they have a name, but when you are 61 and 3/4 your brain locks up quit often there fore I can't remember the name. Hope this has helped you some. If you look at the sprokets one of them should be adj.to center the rolls when you tighten the chain also.

Hey Jimmy,
Gib keys is the name I think your looking for. I'm not sure of the set up on this particular haybine but sounds like the rolls may just be out of time and need to be adjusted, chains could be stretched/missing. Could be a bearing out on one end of the roller too for that matter.
I have had my 469 haybine since 1990 and have only replaced one roller bearing.

If you have a 489, there is no sprockets or gib keys in this machine. There is a gearbox with driveshafts connecting to the rollers. Check and see if maybe the hubs that the driveshafts hook to are not excessively loose. If so, that is probably where your noise is coming from when the rollers contact each other. If they are worn, I have seen the rollers try to climb on top of one another, and when they let go it will make a terrible noise. As far as a service manual see your local New Holland dealer.

Travis,
Since you mentioned it I do recall there being driveshafts to the rollers. I have not looked at one of that model in a long long time. I personally never liked the set up of that model because of all of the damage I HAVE seen on the ones I have looked at. I'm sure they have to have their good points.
