| | Posted: Wed Jan 15, 2014 8:24 pm Post subject: Gleaner K Question | I bought a Gleaner K combine with a 238 head the other day and it has a few small things to fix on it, one of the things I have no clue about is the lever that you can speed it up and down like a hydrostatic. The pulley on the left hand side controls it, the previous owner stated it will speed up but not slow down, it looks like the bearing behind the pulley might have more clearance on one side than the other, anyone ever had this problem on one and know what might be wrong?

You have two levers in the cab, next to the seat...both work up and down, as well as fore and aft. One closest to driver is the variable speed..fore and aft changes ground speed, while raising/lowering the lever raises and lowers the header. Second lever is for reel raise/lower, and reel speed, for the grain head.
A general cleaning of the variable speed pulley sheaves may clear up the problem. Belt tension is also important- check the OP manual for getting the right setting re how deep the belt rides in the pulley.
After disassembly and cleaning- check for a grease zerk. Don't get wild about greasing or the belt gets greasy and slips, but it needs some lube if it's gonna move the sheave half. BTW- cyl speed is controlled by a similar setup on the right side of the machine...same rules apply, or it doesn't move!

In the control tube that goes along the side of the combine has a set screw that will not hold some times and change the travel of the valve spool. As far as the cables go, I spray them with WD40 and that will keep them free.

Your ? about directly across..I think so..it's been decades since the K, but yes..it's called a counter shaft..same below .shaft goes from side to side thru the machine in the lower thresher housing, driving the head, pulleys/drives on each side. Typical Gleaner simplicity. Some criticize..others wish for!

Trust me..you don't want to see that happen! Well, Zombies are still worse, but I think that they infect other brands of combines. Gleaners are waaaay tooo pure.
Doug Boll- don't even think about touching this one! I'm having way too much fun supporting my brand of choice! (but I like your friendly banter- Jim)

The man that bought this combine used the grain head only, the corn head hasn't picked over 10 acres!! It has the straw spreader on the back, does it make any difference in corn at all? I wasn't sure if it was better on or off of it. I have a manual coming so hopefully i'll be more familiar after reading it.

To unlatch the lower hooks, there is a tool, normally hanging on the left side of the machine..looks like a solid bar but has a loop near one end (that is used to close the rock door), and the other end has a square hollow in it- that is used to engage the tapered pins that lock the lower hooks.
Push up/down to lock the pin behind the T slot. When you see the slot you'll see which way to go..some combines are up, others down. Do that with the header raised, to take weight/binding off the tapered pin. Lowering the head to the ground, the thresher housing should continue to lower until you can back away.

When attaching a header you need to be perfectly centered on the head and square with it. I Mark centers of the head and the thresher with tape to use as a guide. Chalk or paint stripe works as well.
