If you can correct the problem by moving shims, and it is worth a try, you can do it though a plate on the side of the transmission. Yes there is two differant clutches in the one assembly. But You need, I repeat need, to get a service manual on your tractor before you start. I think that even an I&T (brand of manual) will have this information in it, and they are only $30 to $60 dollars depending on where and how many models that it covers. You can get them from several web sites like Steiner ($33.95 covers all of the D series & 160, 170, 175). You can also get them at most Farm and Homes like Tractor Supply. This board has a vast knowledge, but can't be there while you are doing the work and you will need a referance. Shop manuals are a cheap investment when you try to work on your own equipment. I've been a mechanic for over 22 years and I still use shop manuals daily.
Remember when you are moving shims it is just that, you move them from one spot to another not add or take out.

You can also buy your manuals from this site, and I suggest you do just that. To adjust your power director properly you need to have an assortment of shims in two differant styles as the inner and outer shims differ. Get a book, read up on it, I'm sure you will have more ??? before you procede.

You don't need any shims other than what's supposed to be in there already. The center stack you don't touch. On the outer stacks, you take from the loose side and add to the tight side. You should get a manual and read up on it first.

That was what I thought Mack, but my experance with the Power Director is pretty limited. That is why I say use a manual, it is a cheap investment if you are going to work on your own equipment.

No, thats not right. I just adjusted the P.D. on my D17. The center stack is not the same as the outers. They will not interchange. The manual specifically says NOT to add/remove from the center. Doing so changes the requirement of the links from the front to back. Only move shims from the outer packs as needed.

Your manual is WRONG! Overall thickness of all shims must stay the same. So what would you do if both sides were loose, you can't leave them out?

I'd like to know where you found that information in a service manual, either I&T or Allis, I don't see that statement in either of my manuals. Maybe I did mine wrong??? I got lots of snap in hi & low ranges , and no slip ??? I thought I followed procedure as I studied both books, Did I just get lucky?

If you take .010 out of front or back you musr put .010 in the middle. Front and rear shims are different than middle but front and rear can be used in middle but middle shims cannot be used in front and rear.
It is best to buy shims for middle but short shims can be used in middle. MACK

Straight from my IT manual.
"Thus, on all models, the total thickness of the shim packs is 0.205 and this total thickness must be maintained when adjusting the clutch to avoid changing clutch housing dimensions. For any thickness of shims added or removed from the three shim stacks between the housing and center plate of either clutch pack, a like thickness must be removed or added to the shim stacks between the two center plates."

You don't need any shims besides the ones already in there. Don't worry about measuring the gap, just adjust it until it has a good snap. If you already have a good snap going into low adjusting shims won't fix it.

There are 3 shim packs each low, center, and high side. Little or no oil will come out when you remove the side cover.

so to get this right any shim i pull out needs to go back in the center to move it. or if i pull one out of the center has to go back in on the low side. you just can't take a shim out and leave it out

No, you cannot just pull a shim and leave it out. If you take one out of the low side, yes it needs to go in the center, however, the shims in the center will not work anywhere else.
