vermeer 505 super i supposed to do this?

when baling there is a idler on the left side of the baler next to the main drive chain when the bale gets to about 2.5 ft in diameter the chain starts getting loose on the bottom and tight on top and the idler is coming up.( i thought that is where it was skipping teeth but after watching it more closely its the main drive chain that was slipping but i tightend the tensioner on it and stopped that). i first thought something was wrong with the chain and idler getting tight but i dont see noway that its not going to raise up, so i think now that its supposed to do that as the bale grows the more the tensioner goes up,then once dump the bale and close tailgate the idler goes back down. is that normal? hopefully this picture will show what im talking about.

I can't help on the issue at hand, but I'll day that your sprockets look like they've been running a stretched chain for a while. Atleast the yellow one on the right where the teeth look worn. Cheap insurance is new chain. It's much easier to replace a chain than it is a sprocket, as well as much cheaper.

I've gotta tear into our chopper that we've had for 2 years now because the previous owner never replaced any of the chains.

worn out sprocket. Maybe stretched/worn chain. Improvised spring tensioner on idler arm. Check for play in the bearing behind that worn-out sprocket. Get a pry bar on that shaft and see if there is vertical movement indicating a bearing failure. I suspect at least three of the issues above are in play. Joe
 
im not saying its not work or chain stretched, but i think the sprocket still has plenty of life in it. ill check bearing tomarrow but dont think thats a problem either.

Has there been a change made to that idler? A spring loaded idler should not be on the pull side of that chain. Look at pictures or another baler to see if that idler should be on the boton side of that chain.
 
every picture i see and my manual shows the idler to be in the correct position. its runs smooth and doesnt jump the idler just raises up as the bale grows and allows the bottom of the chain to go real slack. maybe normal but i have no idea
 
It will definitely work for a while yet, but the problem arises as the sprocket starts to wear like that, it stretches the chain and then the chain in turn wears the sprocket more. I worked at a sprocket shop for years and saw some that were even worse than you show.

Farmers would bring them in and we'd either make a new one completely, or cut the old one off the hub and weld on a new one.

I wonder if a drive roller inside baler is worn enough compared to the other drive rollers to affect the forming belts causing drive roller rpm's to become different?
 
just spoke with the guy i bought it from and he wanted me to check the number of sprocket teeth. counted them and front outer sprocket has one more tooth than its supposed to the rest are correct hope that is what is causing my problems.
 

Got my 505 I out to bale hay. Idler sprocket was slipped off the chain as pictured in other posts in these threads. I had put a short length of pipe on the threaded rod that adjusts the tension the take up some of the threads. The flat end of the tensioner rod toward the top of the baler was all the way down into the hole so that no more tension could be added by tightening the nuts. The short answer seems to be to take out a link in the chain, but for now I have removed the threaded ros and pulled the spring tight enough to slip the eye on the spring into the hole where the rod was. The sprockets don't appear to be worn much and AIRC I put at least one new sprocket on there.

Was going to bale, but there are clouds and lightening around. Will check radar, but probably will wait until tomorrow.

Well, the storms rattled and rumbled and didn't rain here. After a delay I tried the baler. Clogged the baler on the first bale, took it back to the house and applied a steel rod to the clogs, with help from wife got it going again. Baled a couple of bales.

The idler does NOT spread apart with hay in baler. I checked with it half full and full. I don't know what's going on with your baler.

If your chain is that stretched.... REPLACE IT. Period. Taking out a link doesn't help any. A stretched chain will only wear your sprockets faster. When you can get a 10' length of #60 chain for $35 (or more for better stuff) it's cheap and easy insurance that you won't wear out your sprockets, that will cost you lots of time, and money to replace them. Not to mention it could make the difference of getting the hay off before a rain or letting it get rained on.

Here's a chain that should have been replaced long ago....



But because the previous owner never did, I get to replace all of the sprockets. This one was what drove the feed rolls on our 892 chopper. Some of them are over $200 from the dealer, and unless you are a machinist like myself it'll cost you an arm and a leg to have a shop fix some of these too. One of the sprockets is 3 welded to a common hub, so to replace the middle sprocket, it's gonna take some work.

Just doesn't seem right, chain tensioner should be on the slack side, why does the chain go slack on the bottom?

Can't see how that is right.

Are you stopping the baler and then looking at it? Is a bigger bale momentum turning the shafts after you stop the baler, and that is what you are seeing?

i have some new chains and sprockets on the way supposed to be here today and got some hay to bale tomarrow hope all goes well. im pretty sure the wrong number of teeth on the one sprocket is what was causing the idler to ride up. fingers crossed.
 
baled 32 bales yesterday the idler stayed down like it was supposed to, all the problems was from somebody putting a on a sprocket with one extra tooth.
