Pete, I've been going over this stupid Behlen setup over and over, and just can't figure out how the roll pins go in these V shaped notches. I looked up the roll pins on the CaseIH site, and I have all the correct length roll pins. I painted the sections different colors to make them stand out better, I'll clean that off once I figure out what I'm doing. In the picture that has just the shaft in it, is the roll pin supposed to pin both inner and outer pieces of the V? Or is it supposed to just lock the inner piece in place? Then on the other picture with the shaft and the collar, is the roll pin only supposed to lock the outer V shaped piece? Obviously it can't be driven down to lock both pieces as the V shaped notches don't line up. But, if I can't drive that outer roll pin in all the way, it doesn't fit in that tube that goes in the housing around it. I'm having a hard time explaining it the way I want to, and I hope you understand what I mean here. I'm very grateful with your previous answers you gave me as to lining up the spools with the ports and such. Maybe I'm just dense, but I'm having a heck of a time figuring out these 2 small roll pins and 2 V grooves. Thanks again

Boy, you are taxing my memory here. I can't tell you for sure just how to assemble it. All I can say is that when it is correct, that when you turn the shaft while holding that sleeve, the v shaped device will cause the spool to move back and forth. The short pin just goes in flush into the sleeve while at the same time engaging the slots in the v, while the longer pin is driven into the shaft while extruding enough to engage the other side of the v. Also, when installed in sleeve you cannot get the shaft out until you turn it part way and drive one of those(can't recall which one) pins down in farther. Don't know if that helps you. Hey, bring it over and I will get it together for you.

One other thing, if you notice the large roll pin holding sleeve to gear shaft has a hole in center. That hole goes toward the gear motor. Also, when shimming the gear motor, don't get it too tight as it will bind when it gets warmed up. Of course, too loose allows excessive leakage. I also used to weaken that centering spring between the balls (if you have new spring) so it takes less effort to start the turning cycle.

When working at the dealer, I repaired a unit and it had a broken spring. Put in new spring and g uy was all upset because he could turn wheel with one finger before. So, I took it apart and cut off spring until I got it to take very little effort and made him happy. Worst part was he was a pretty good friend of mine also but he could be a pain to repair things for. Especially before I got to know him real well.
 
I'm gonna keep on trying... Thanks for the additional info Pete. I'd love to bring it over and meet you, but I haven't been to MN in a long time and probably won't anytime soon. I'm so glad we have guys like you that were there, that can now give us the inside story. Thanks for all your info over the years Pete!
