gleaner M2 header drive shaft LH bearing

rockyridgefarm · Sep 24, 2016

Hey all,

Got my Gleaner M2 home a couple weeks ago and was looking it over. I noticed the driveshaft didn't line up to connect the head. On further inspection, I noticed the bearing on the LH (ladder) side is out. I pulled the variable speed belt & pulley, pulled the bearing, and found that it did not have its locking collar. The bearing had spun on the shaft, ruining the shaft. I have a pair of spare combines with shafts and found they did not have locking collars, either. So, is this bearing supposed to be set screw style, but people put in collar style without the collar, or did they come from the factory this way?

Also, I'm very nervous about using the 20 foot floating cutterbar head. I've been searching for a 15 or 16 foot flex head, but they're either very expensive, or are too far away. The search continues...

They will handle a 20 foot header, dead slow in a heavy crop. Mine is much happier
with a 15 foot, sometimes that bit of increase in ground speed will help feed in a
short crop like soys or direct cut edibles. Ben

What your issue with a 20 foot header on a M2???? That is what 90% of the fellow around here ran on an M2. Soybeans anymore are pretty clean compared to the weeding one years ago and they where cut back then with a 20 foot header. The drive power to run a 20 foot header would be way less than running a corn head. The weight would be less than a six row corn head too.

I worked on my F series of combines drive a few times, have not had to mess with the M3 yet so can't help you off hand.

We can look up parts online through Agco web page, it takes some effort but you could see what is there from the factory.

My M3 handles the 20 foot great, my F3 handled a 15 foot great, you should be fine with the 20 foot. A tad slower in beans means the sickle
has time to cut better!

Agco parts book says collar not used on left side.

Thanks for the input regarding M2 with 20 foot head. 'Round here, there's a lot of 9500s running 20 foot heads. 6620SH are pretty much ALL running 15 or 16 foot heads. I kinda thought my M2 has capacity closer to a 6620SH versus a 9500. As far as I know, this is the only M2 for miles around. Most combines are Deeres or Case IHs. I'm building my own boneyard, and have 2 more M2s for parts. Don't tell my wife...

Also, I think a 300 series flex head would be better than a series 2 floating cutterbar head. Maybe I'm wrong?

As far as no locking collar, what's supposed to keep the shaft from spinning inside the inner race? This shaft is spun bad enough that I'm swapping out a shaft from one of my boneyard combines tomorrow.
