Combines feeder house plugging

You are back feeding the front chain. Do you have in fast speedIJ Big pulley on RH side front and little on the back. And also yes your slip clutch is probably bad. Remember to keep it greased. Rebuild kits are available. Build it to the max. Put in new 'bullets' and double spring all of them. Also check for wear on outer shells inside ridges where the bullets slip. In an emergency you can turn the bullets around and shim the springs. Keep in mind one can speed up the throat chain with 71374737 and matching belt 71368809. this really helps in some crops - It also lets one use slow speed on the sheave with increased capacity in corn. Fianlly remember to inspect the transition area at throat pivot. We have seen some deterioration here and bending. This will cause a blockage as well. IF you find a problem here you can put in the R75 parts whch are 1_4 " thick. lowering the front floor under the drive sprockets is a nice thing to do here as well. I wish NDDAN would put out a blue print on his mods which really help in this area.

Yes It is on the fast side. I will try the slip clutch,is there anything I should know when taking one apart. Thanks for the advice!

First you should get them feeding as well as posible. When you get up to speed the header will likely work better. Have you had the rear chain block down in grain rear position since having the problemIJ Check for proper tention of corn varible belt (there should be .100" gap between front sheaves). Check for proper tention of right feeder belt and be sure idler arm pivots freely. Make sure rear feed belt isn't stretched or wore enough for the idler arm to be up against or near iron that prevents violent swing up of tentioner when belt is removed. Make sure no mud in Vs of pulleys. Front slip clutch is likely the sliping one but can be caused by rear clutch slipping first. It is just as important to grease rear clutch as front clutch as tbran points out. If slip clutches have been severly shorted of grease the splines will wear and it will be to late to just bring them back to life by greasing (needs teardown or replacement). A couple things that drove me crazy tring to find why clutches were slipping to easy was bearing failing and draging very excessively and spud that supports feeder housing to pivot area was coming loose. One of these things or what tbran describes has got to be your problem because I believe you should be going at least twice if not three times as fast. Good luck

When you say double up the springs. Are you putting in an extra set or just putting one inside of the other. Have not taken it apart yet but the rebiuld kit has 8 bullets and if I understand right 8 inner and 8 outer springs. They also are telling me I need three of the kits plus a new seal kit. With the price of gas I don't want to have to go back. Thanks for your time!

Hey tbran,do you change the belt to slow speed for cornIJ

No, not unless we have the speed up lat Tilt bigger sheave, or unless we have damage to white corn or pop corn.

I mean all inner springs inside the big springs. You can use a little flat washer or lock washer for a shim in an emergency. (or to add alittle more ump, just do not get into a coil bind situation or you can break the shaft)

You might want to try a Posifeed roller, front drum of second feeder chain. Check with loewen, they may be willing to run a test with you.

30" rows or narrow rowsIJIf 30's you could put belting on the reel to push the beans better.Have you tried increasing ground speedIJIf the beans are bunching on the head,it doesn't take much to slip the feeder house clutch.

15 inch rows, and they are bunching up on the platform. Changed to small drive and now moveing at 3.5 to 4.5 mph. Did some green beans just to get the field done had half there leaves still green was still moving at 2 mph. Why it is working better on the wrong speed I don't knowIJ
