Expert help needed on JD 8820 T2 combine repair

Putting an upright unloading augar in the bin on the left side and also putting in a new $880 metal housing that contains the upright augar. The old housing came out fine but was very worn out. The combine had the chains jump and spread the bin sometime before we owned it but it was fixed as best as could be done. We are having trouble lining up the housing to get all the bolts in as the bottom part is wedged to the left and won't move around.

Is it ever needed to somehow adjust the turret where this piece goes into to line up the bolt holes and make it fit back together?

We have only done one of these on one other combine and it went together okay.

I also posted this on the JD page.

The horizontal turret auger needs to be timed to the fountain auger and the best way to do that is spray a paint mark through the access door on top. After the bottom is out and you lower the old auger down then index the paint mark against the housing. Note where the top of the curl is on the old auger because that is where the top of the curl needs to be on the replacement. Don't wait till the day before going to the field as even with all that observation you can still get it "out of time" due to lining up the spline. You will have to run it to know if something is not right as it will probably clunk when you run it. If it does clunk then you will have to look through the access door on top to see if it needs to be advanced a spline or the opposite.

We had to put the forklift under the horizontal unloading tube, loosen the turret bolts top and bottom, move it around, tighten it back up. It was hard work and had to drill out some holes in the sump a little to get bolts in. Looks fine now, but very much harder than it should have been!

Thanks for the advice on timing the augers. We have the full JD service book which helps out alot. The first one we ever did we just put it back together but then was talking to someone before we ran it and messed it up. Had to pull it out and make it right!

I painted a line on the bottom of the upright auger to show where the top flighting is. We will time it when we install the horizontal one. That is Sunday's job!
