pins you are talking about is this where modules lock in on bottom?, remove cover on r/h side of machine, look up above doors will see bolts that hold r/h side in place have seen them get loose or fall out, then zero concave per manual, is this something that just hapened?, we made a switch where you could disconnect wiring to actuator so you could adjust by yourself, other wise it takes two people so ya can see whats going on, make life alot easier, scott.

yes pins on bottom. its like the contact point where the bolts go isnt true and just as the bolts get tight the mating surfaces meet and lift bottom of concave off of the pins. i just bought this combine 05 with 700 hrs lots of updates .you told redman to take the 07.can you tell me what other things have changed by 07.dealer said combines are all the same. going to put stiffeners on feeder floor has pro 600 gps heavy bubble up auger as well as some changes in fan drive. I paid 170 canadian with p/u header. combine in excellent cond. deal doesnt sound as good as redmans though. give me more info on helicals, cone and any other improvments. im trying to upgrade to 2010 standards if possibly.

Concaves not resting on pins is no big deal. Tape some 3/8 or 7/16 washers with duct tape on top edge of flat surface towards rotor where bolts go thru. When you tighten the bolts up this will force concave down on pins. They all do it. Not a big deal unless you realy want to get concaves zeroed as close as possible. Sometimes necesary in hard thresh conditions.
