My other 60A is 801 combines older than this one, and it doesn't shake...

Yup but you said the PO rebuilt that one so in alot of places it isn't older it is alot younger.

I did have the belt off over the weekend, and spinning it by hand, I noticed it would spin a while, and gradually stop. No heavy spot.

You Could've said that earlier....

Sorry.

However, my 1st post does say the cylinder has an equal amount of rubber on each bar. That was kind of a if/then statement.

We might have it narrowed down to the problem now since I talked to Creston on the phone. Straw rack may need to be slowed down. The drive pulley on the back may need shims put in or taken out to slow the rack speed.

35 combines and 15 forage harvesters. mostly allis combines and equipment.WTB 2 row cornhead for a 90

Don't know if these will help.

Take the cylinder drive belt off of the cylinder pulley and see if there is a heavy spot in the cylinder if that makes sense.

Also, take the separator belt off and move the straw rack by hand, check the wooden pitman arms and make sure they are not egged out and needing replacement. Also check and make sure the wooden pivot blocks on the left side of the straw rack are tight. Those two shouldnt make a diffence in your problem but have seen them cause other issues. I might know where there are some NOS blocks that can by sent your way. Wink

The pitman arms were new this spring, and are still in great shape.

The pivot blocks on the straw rack were shot this spring (only one was still there, and it was broke) I used the old one for a pattern and made some new ones out of soft maple because that's all I had, and harvest was in less than a week. The holes are a little egged, but not too bad I don't think.

What kind of wood were the original blocks made of, as well as the wood chain guides?

An open eye is much more observant than an open mouth

you'd shake too if you was that old!

Like I said carl shaker bearings too. I had a busted bearing on the shaker shaft that caused a lot of shaking too.

Ohh absolutely!! They can make a mess of things. Especially on an axial flow. Doing a shaker overhaul on a 2588 right now at work.

Only thing that leads me towards the cylinder is Creston said with more rpm on the cylinder the more it shakes. If he leaves the belt off for the shaker, it still shakes.

What is a shaker shaft? You mean the straw rack? Which shaft? The one that the "Y"ish shaped thing rocks on?

Like I said earlier. Check the cylinder as I stated.

Mistake twist right and then left.

Maybe a new belt would fix the twisting problem. They are pretty old.

The thing I find odd is this combine shakes like no other (Maybe because it's so old, battered, and scarred), and my other 60A (Which shows a lot of evidence of being rebuilt by the PO) sits almost prefectly still at operating speed.

When I had a belt doing that I put a new belt on and the problem went away. Belt was getting old and weak.

As for the shaking, mine shakes quite a bit and it's completely rebuilt. The biggest thing is the Walker moving back and forth in the machine. No different then new combines, but when's it's side ways it's more noticeable.

Mine doesn't change with the cylinder speed at all. Only thing that changed is the hum. Check the cylinder bearings, mine on the right side were gone and wore through the housing. Another thing to try is take the belt off the cylinder and spin it. It should not stop in the same spot every time. If it does, you'll notice it rock back and forth til it stops in that spot. That means your cylinder is off balance.

one of dad's shook a lot, and the other one didn't. it never hampered it's working ability tho.
