Hesston 5530 Baler Bouncing Problem

RedBarnFarm · Jul 7, 2015

I have a Hesston 5530 round baler and for lack a better description when running even empty is bouncing. I've attached a video link. Any ideas what the problem might be? Still making a good bale but does that bouncing the whole time.Thanks!

Rollers out of balance,..bent roller maybe?

Oops broke the video link. Here it is again.

Looks like a bent roller or roller shaft somewhere causing the chain to go slack/tight too.

Thanks guys. I will check that out when the rain lets up. Hopefully not too expensive or labor intensive, but my guess is it will be both.

We have a 5530 also. Try letting the gate down on the tension release pins(I see you had them in there) and then run it some more and see if you still get the clunking. With all of the tension off, the belts should not turn. This will eliminate the rollers as a problem. The main drive (rubber) roller will still turn as it is driven from the long chain. Make sure there is no old hay wrapped around any roller also.

Email me if you want, I maintain 3-4 of this type(5530 and 530) for some folks around here. It will be interesting to see what you find.

With tension pins in and belts not spinning there is no bounce or problem. As soon as I put tension back on the belts the bouncing starts again.

With the tension off the belts, try to turn each roller by hand,looking for bad bearings. Roller bearings are not very hard to change. Check all of your belt lacings also. Some of the rollers are kind of hard to get to with the gate down. A bad roller bearing should be making more noise than just that clunk.

Well I climbed in through the belts and turned the rollers by hand. I couldn't feel anything that seemed rough or out of place. The belt
laces all looked ok to me. Everything seemed tight fitting still and I didn't see any signs of a bearing out. The larger rubber roller at the
top was harder to check but I pushed up from underneath it and it didn't give or have any slack up and down. I am not sure if this is related
or not it might be but while baling it broke that 50 inch belt clean in two and the lower pick up chain hopped off at the same time. I
replaced the belt and put the chain back on and baled 70 bales with it since then. Not sure if that jerking/bouncing caused the belt to break
or if that was an unrelated incident.

Check and see if there is a bunch of twine wrapped around the pick up tine bars. That is real easy to see from the back with the tailgate up. Something caused that belt to break. I know they were turning even with the tension off the belts, but it is worth a look. Check all of the wooden belt idlers, there is one for the pickup drive that is kind of buried, you have to take that lower sheet metal guard off to get to it. Also check the main drive shaft bearings and the bearings at each end of the square 'starter' shaft. You may have have to use a pry bar to check for looseness. I also have one of those mechanic's stethoscopes that works well on bearings. Just be real careful with around the moving chains. I speak from experience!

I am trying to think of other things to check.

Just looked at your video again and it dawned on me that the clunk is not timed with a full revolution of the belts, it happens more with more frequency. I am slow on the uptake most days! But it is still making the spring loaded roller bounce. Are all of the big springs okay? This problem is real interesting to me because we have the same type of baler.

I'm going to go over it again here in a bit and see what I find. I will look at the big springs and see if I see anything there. You may be on to something about that belt breaking I bet I have some twine in the pick up assembly. I will look at that too and let you know what I find. Thanks!

GarryinNC · Jul 9, 2015

Also, has the long chain been lubricated? Any 'kinks in it's links'? Is the long chain riding up on the big sprocket? You will have to unbolt the side cover to see this. Check for chain wear also: can you pull the chain off of the sprockets somewhat when everything is stationary. Chain is cheap compared to the price of the sprockets. Worn chain is hard on the teeth.

RedBarnFarm · Jul 9, 2015

Looking at it right now. I did find some string in the pick up attachment to clean out so that might account for the belt issue. The large springs look good from what I can tell. The two shorter (lower) springs are fairly new, still got the paint and no rust on them. I think they were replaced right before I bought it so they have about 1000 bales on them. Going to take all the covers off and inspect the chains as you suggest. Will also take a pry bar to that square roller.

GarryinNC · Jul 9, 2015

Believe it or not, but all four of those springs are the same part number. The upper ones just have some preload on them. The upper ones are also harder to change but seem to break less frequently.

RedBarnFarm · Jul 10, 2015

Well I cleaned some string off and inspected everything again and couldn't locate anything. I took the pins out and shut the gate and turned it on and no bounce this time. I don't think it is fixed though as when it started while baling last time it seemed to do it sometimes and then stop then start again. Anyhow as soon as I opened the gate some it started bouncing. So my question to you is do you cut off the pto when dumping a bale with yours or do you leave it running?

bison · Jul 10, 2015

Could it be a PTO problem with the tractor?
Hydraulics on the PTO cutting in and out?

GarryinNC · Jul 10, 2015

Yes you definitely have to stop the PTO before dumping bale on these. Manual says so too. On the one I have without bale ramps: I stop tractor and back up a few feet with the baler still running, (this allows the bale to compress some), then Thread the twine, stop pto ,dump bale, pull up clear of bale and close the gate. I leave it running at 540 when putting twine on the bale. Start out on a new bale at less than 540 until the new roll starts spinning.

I kept starting and pausing your video and kept watching that one chain bounce in unison with the rest. Is it the result or cause of problem. Watch and pause at 11-18 secs(on the side shot)the left chain where it goes up.

bison · Jul 11, 2015

Check the chains for a bad section or one worn chain and 1 good one if there are 2 seperate chains drive the belt drive rollers, when one roller stays behind it can't catch up and either the roller has to every so often when the tension builds or the chain has to jump a tooth.
