Combines rear feeder chain

the safest and long run most economical cure is to replace the ca550 chain with 557. I assssume you have a r50 with 550 chain. We have found a 557 chain that has the 3_8 bolt holes and is a nice upgrade to a slightly stronger chain.(approx 210 bucks for both sides) Your slats will need to be reused and as you replace them make sure you do not torque the slats by using a air gun with out making sure the slats are square to the chain. The natural righty-tighty will cause one side to lead the other unless care is taken to prevent this occurance. The plant had a production run problem with this several yrs ago.. due to the nature of the beast the left side is the one slack rightIJ See posts below on stripper brackets and feeding and etc.

I have better luck installing the chain with bolts loose, rolling it over a few times by hand, and then tightening them. After lots of trouble when I first bought the combine, I have found that being fussy at installation time pays off in the end. Tom in MN

I knew I was fogetting something, it's a '92 R-52, tbran I read the other posting are you saying the slates are too tightIJ that I should loosen them and then retighten themIJ [ it's the ladder side that droops] also I plan to do the Hyper upgrades this winter I assume this is best done with the rotor out correctIJ This web site is a big help to me since our local dealer went broke AGCO doesn't seem too concerned that we now have to drive 50_60 miles some even a lot more for parts. so this site is a big help if I sound simple will I'm not, I just like to have all the info. I think I need before I start a project so it's done right the first time! thanks again for all the help so far you guys are great! take care and be safe!

RUN 3 2001 MACHINES,HAD THAT PROMBlEM WITH 2 OF THEM DOING THE SAME THING. THE FRONT FEED CHAIN WOUlD JUMP OFF All THREE DRIVE SPROCKETS,IT HAPPEND TO THE ONE 8 OR 9 TIMES AND THE OTHER MAYBE 5 TIMES. NEVER SEEMED TO HAPPEN IN ANY ONE CONDITION SOMETIMES IT WOUlD BE lIGHT STRAW AND OTHER TIMES IT MIGHT BE HEAVY SRAW, NEVER COUlD UNDERSTAND IT.

What model of Gleaner do you have IJ I had a lot of trouble with the rear chain jumping on my C62. Problem turned out to be worn cylinder bars. Sounds like your combine is new though.

R65 with 95 acres wheat through it. It plugged on left side where there may still be some returning even though helical kit is installed. It did a super job in threshing the (hard thresh) wheat but we did have some plugging in the feederhouse.

Its just the nature of the beast in tough straw. I tried everything to keep chains from jumping. You have to learn to live with it you want to run a gleaner.

That is such a load of crap "you just have to live with it if you want to run a gleaner." There is obviously something wrong with the way it is being fed into the machine and any machine with an uneven feed whether it be a gleaner or not will jump chains.

Sorry about getting so upset about comments like that. Every machine fresh out of the box has their own problems. I was just at a field demo last week and arrived there just in time to see a fire being put out on the wonderful 8010 IH machine. Was not impressed with the vintage "760 Massey" return system that they have on them if you guys know what I am talking about. Back to the question now why the chain is jumping. Make sure that you have the optimum feed into it starting at the header. Do not know what you are running for a head. Make sure that the auger is adusted back and that the fingers are adjusted so they are just clearing the bottom of the platform. Next thing that I have found out about the 3rd helical extention is that it is not for all conditions. Have had trouble with jumping of the left side of rear chain because of it. Had straw rap around the sprocket in that spot and cause the chain to jump. I removed it and problem solved and gained .3 to .5 miles an hour on the same day and field. Do not ask me why, had this problem on a 62 and a 72. I don't mean to be stepping on anyones toes but this is what I have found in some conditions. This was in 65 bushel wheat with a lot of straw.

I was told this year that you should take out the stripper bar ( the one in front of the rear shaft ) when cutting wheat. This was after I had plugged really bad several times, bent the bar, made a new one, bent the new bar, broke the chain, straighten the new bar put back in with new chain and bent it again. Then was told you should take it out for wheat. I have been running the R series since 1990 and never knew you should take out that stripper bar. Of course I don't know when they started to put it in either. Just my 2 cents worth Kurt
