Combines 324 feeding trouble

[R_O_M]

I am not familiar with the 324 grain head but on our 500 series flex head [ R62 ] we have always had some feeding problems in cereals. The problem has almost been eliminated by installing two" Posifeed rollers" [ see earlier post ] in the feeder house. We also discovered a few years ago that our main front spiral auger was running way under its specified r. p.m. since new, due to the wrong sprocket being factory fitted. We speeded that up to the high range of specified revs and that made a huge difference. The crop material was building up under the auger and spilling over the top due to the slow clearance of the crop material. Correct clearance under the auger for different crop conditions is also important. Knife slap; Check trunnion bearings, ie. the back and front bearings on the wobble box bearing housing for any movement at all. Carefully remove shims to take any slap out of these bearings. Also check the the lower pivot bearing under the wobble box bearing housing. Any movement here usually means a bearing plate replacement and maybe a bearing replacement if the bearing ball is worn. Any movement in any of these bearings creates a fair bit of knocking and banging. Installing a wobble box flywheel as shown in" HYPER MODS _ Misc Rotary Mods _ Heddy's Hyper Mods" can really smooth out the knife drive and makes a huge difference to the life of all the knife drive components. Hope this is of some help! Cheers!

Yes the tall flighting worked for us. Did many of them and have lots of flighting in the shed. First we installed the factory extended flighting for finger area than we grew that flighting to 3" then we grew it to 4" then we extended the 4" from left and right to cross a center line in finger area. The final move kept the finger area very clean but to take it one step further you can weld keystock onto flighting you added right ahead of feed chain. It would take about 10 or 12 pieces of 3_8" X 3.5" evenly welded to flow side of new flighting. One end of keystock against tube and other out toward edge of flighting. I would only add the keystock if not happy with flighting only for it may cause a bit of shelling. I would add about twice as many gussets to hold flighting as the rest of header. Most of the time the sickle slap can be removed by installing either one or two sizes smaller drive pulley. The standard one will cut at 10MPH give or take. Rolf's idea of the wobble box drive pulley flywheel weight may well work also but why don't you slow her down first. Oh and by the way if you have straw flowing around the back of auger before it gets to center you need to add channel iron stripper bar under auger in front of currant strippers. Good luck

Sorry to jump ahead of you Max. Should of hit refresh before posting. Anyway good tips. I wonder why you had wrong gear driving auger. I believe Gleaner put shallower pitch flighting on auger for Australia which would require a faster auger speed to handle the same amount of straw. 24" as compared to 30" pitch. If I remember right Rolf said you guys got front about the same time they were playing with pitch of flighting. Cheers

I would be interested in buying the flighting from you if you give me a phn I will call you tommorrow thanks

Thanks Dan. I get pretty humble when I see the level of expertise you guys have. Rolf and I have had to do almost all the experimenting on our own, until this site came along, although I admit, I started experimenting on combines [ for those not in the know they are called" Headers" in Oz] when I was about 17 and Rolf wasn't even a twinkle in my eye. Re the auger speed; it was a bit of a shock to find the auger on the R62 only running at about 2_3's reccommended speed. Speeding up made a big difference. The small drive sprocket was wrong. Our N7 had a 30 inch pitch and we always had feeding problems. We only discovered that there was a 24 inch pitch " for Australian conditions" listed in the parts book, shortly before selling it. Only a few came out here as even the agents did not seem to know of this option. We later found one in the district on an N7. The owners could not understand why everybody complained about feeding problems.Theirs fed beautifully all the time. Its interesting that the 800 series front has a 27 inch pitch flight and a larger diameter which reduces the angle at which the flight meets the cut crop. There appears to be a crtitical angle for the crop _ auger-flight angle above which the cut crop will be dragged over the top of the tube. The 800 series fronts seems to be going well out here. Regards and Cheers!

Mmmmm! M.O.M. He was meant to go to his Alzheimer's meeting's but keep's forgetting to go!!!! Just a small correction!!!! (sorry daddy!!!!!!) We only found out about the 24 inch pitch flighting after we had brought the 62 in 94 I was sitting down reading the part's book ( He was to cheap to let me have a TV for 14 years!!!!! or was it because I was really bored!!!! ) and found in the part's book that we could have order the 24 inch pitch flighting if we had known that it was available!!! even then M.O.M had to change the order during the year, as we found that we could get a 30 ft flex 500 instead of a standared ridged front, as one of our neighbors had ordered a 500 flex one all ready, and if only we had a decent dealer (are you listing AGCO!!!!!) we might have had the 24 inch flighting as well!!!!! And as for the twinkle in his eye! he might think Im a wrinkle in his Butt Now! Rolf See to tomorrow Max! Your loving Son. PS: Iv been on the net since 94, and a couple of years ago I suggested that ROM get on to net as well!( saves me from relaying information!) well I think I created a monster!!!!!!!

Forgot to mention Bill. Do not get any sparks period on the cab windows. The blue glass is very sensative to sparks. Believe me I learned that the hard way!!!!!!
