Anyone know of a update to a 2188 unloader tokeep it from hitiing so hard when you push the button? I have heard of an orfice to slow the engagement. My dealer says , i think i might have heard about that once.
I broke a brand new shaft. 2nd in3 seasons.

Haven't heard of that but what about putting a flow control on the line? Then it could be "dialed in" to engage just right.

Dan, I dont know for sure on the 21xx, but yes, there is an orifice at the hose to block connection on the 1680s. I drilled mine out a bit as it was just too slow. If you bought yours used, and they have that orifice, it may have been drilled.

Look thru the parts online and see if you can find it. It will either be in the hydraulic section or the unloader section. But mine was right at the valve block, behind the hose connection. The second 1680 that we just bought this season is stock and I about dumped grass on the ground waiting for it to swing out because I am so used the drill out one being quick. But I run the short auger so far and it does not have as much power smashing up the swing system.

The hydraulic cylinder has some special pieces in it did you know. not a stock standard hydraulic cylinder
the unloading auger on our 2188 is slow, much slower than the 2388. i wanted to speed it up and always thought it was the port in the cylinder that is the problem. anyhow the port in the cylinder is very small and after looking at it and the internals i just put it back together.... rather than creating another problem. Maybe there is an orifice elsewhere, if i remember ill have a look in the parts book.

I guess i should have been clearer, i am refering too the small cylinder that starts the unloading gearbox . The shafts i am breaking is the one with the spline that goes into the vertical auger. Put a new gearbox in friaday night.
Then yesterday ,same machine , broke the chaffer rail on the left side,grrrrrrrrrrrr. I think its time to retire the ol girls ,in talks now on a different machine.. If i didnt have clovers to do i proabably wouldnt even get in a hurry to fix it.

Case IH # 327679A1 is the orifice you want. It goes in the upper port on the cylinder. It is listed on 2004 & up 2388 for that purpose....

Blury eyed and didnt read it properly.....

you might want to read this http://www.thecombineforum.com/forums/7-case-ih/62953-2188-chaffer-bolt-holes.html if you have sieve issues.
Its all fixable and is better than factory if you make it that way.

I hope you put in a new hex shaft too. If you can hear a ticking that is likely the problem. We hammered out a rail and tore bolts on the sieve hangers because the hex shaft was badly worn.
