Gleaner K Issue

[njooshka]

I am running a Gleaner K for corn. As I was finishing up the other night, I heard a loud squeal and shut everything down. I have cleaned out inside the rock hopper and the raddle cover. The cylinder now spins freely, and everything seems to run fine except the raddle doesn't move at all. All of the chains and belts are moving so I am at a loss as to why the raddle is just sitting there. Being in WV, there aren't a lot of mentors for someone doing row crops. The manual is less than helpful and I cannot find a single helpful video.

There's a slip clutch on it. Left side.

I know it's been years, but I'm thinking it's on the right side.
 

[Bob Bancroft]

What is the rock hopper you're referencing?
 

[rrlund]

Ya, right side. I don't know what I was thinking.

My experiences are F and bigger, but typically the K was mostly built the same.....

I had a chain jump off and lock up and mess up a sprocket now and then, the sprocket would then spin on the shaft.so it looked like things were being driven, but the shaft itself was still.

The slip clutch on the right side can get weak, then you barely hear it ratcheting over on itself, slipping.

A neighbor had a shaft break in half in the middle of the machine; so it looked like things were turning but only half of the shaft was, other side wasnt. Need to look at both sides of each shaft......

The clean grain slip clutch back side of the spring was held to the shaft with a roll pin. The roll pin broke, so the spring could move back to the bearing, making the spring very weak. The slip clutch slipped constantly, had to take everything off the shaft to realize what the issue was, it looked normal because the spring was covering the hole/ busted roll pin. I dont know if the raddle slip clutch is built the same.

You got something like this going on, an odd thing.....

With the machine completely off, can you or have someone else turn the right hand pulley by hand, and can more slowly inspect what is and isnt turning, what is and isnt making noise. If you have a stalk chopper on it that belt makes it easy to spin by hand slowly.

If the slip clutch driving the raddle is not ratcheting, then the inner part is loose on the drive shaft or the spring tension is gone keeping the Jaws apart.

I agree with Paul 100 percent. Turn machine by hand. DO NOT INSPECT WITH MACHINE RUNNING.

I am probably calling it the wrong thing. It is a spring loaded door under the combine that is supposed to open when it gets filled with rocks
 

[Bob Bancroft]

There is no storage there for rocks! Any stone bigger than a pebble which doesn't shatter should pop the door open. I've had tough conditions pop the door open.

The raddle slip clutch on my L3 has become pretty weak. I hated to do something aggressive (add washers until it never gives a problem) The last half of harvest, as my luck that leads to bigger problems on a big raddle like that - broken bits all over.....

Need to pull that apart and look over for next season.

Im sure I will remember to do that in time. *

Thank you all for the suggestions. I have located the right slip clutch. I can turn the raddle manually. From what I am reading, I can at least temporarily fix this by adding washers under the nut to compress the spring a bit more. I am going to try that and then see if I can find a replacement for next year.

Possible cause of the rattle chain stopping is that it is too loose. Will follow the sprocket around and catch. But like others have said, probably slip clutch problems now. Had no problem with my K but a couple of F series's have had to have the chain adjusted.

I have inspected the mechanism and the shaft is spinning freely in the jaws. It seems a locking pin has broken. I am sure that it could be easily fixed, but I cannot get the cap screw off because when I turn the wrench, it just spins the whole shaft. I have tried vice grips on the other end, but there is not enough shaft to get good purchase. Any tricks would be greatly appreciated. Do I need to weld a nut on the other end of the shaft?
