The high side of my power director didn't hold, from the side cover I could see the assembly had rust issues. Due to the rust and high price of the replacement friction plates, I got a used one that has the same number of shims in the front and rear packs. When we got the old one out, it was incredibly rusty and 2 of the friction plates are broken in 3 pieces. We got the replacement in and it's definitely tighter than the original but it doesn't feel like it quite snaps over center. I'm wondering if the center shim stack may be too thick? ------------- "Any man who thinks he can be happy and prosperous by letting the government take care of him better take a closer look at the American Indian."

Brian - how far did you tear into the used one? Did you check the rollers for flat spots and wear on the corresponding preload plates? That's the big item for not snapping over into high and staying there. Mike

I didn't really close at the rollers. The shift collar was significantly worn so I swapped the one from my old clutch. Oddly enough, that was about the only part that wasn't rusty. ------------- "Any man who thinks he can be happy and prosperous by letting the government take care of him better take a closer look at the American Indian."

You should never just replace with a used one. You had a used one. Should tear them apart and check them over. MACK |

Brian - I'm going to have Don Bradley tear into my Series IV in the next few weeks to fix this same problem. I put new rollers in the high side and discs in it back in 2006 but didn't do anything with the preload plates. It helped a little but it's not right. I'm going to make sure we take LOTS Of pictures of everything in detail once it is torn down to show these issues.

I'd appreciate any pics of the clutch you come up with. It was getting late on Saturday so we stopped for the night. We're going to investigate the shims and go from there Monday night. Don't really want to have to split it again, at least it's pretty easy to do. ------------- "Any man who thinks he can be happy and prosperous by letting the government take care of him better take a closer look at the American Indian."

| A fella on here posted a very detailed video about two months back on how to shim the power director. It was very detailed and a excellent presentation. Can anyone recall this and post a link to the video??? Ryan |

here's a video from UTube. It's for a D15, but the principles are the same

Thanks Gatz for posting my video....I was away for the weekend and didn't see the post till this morning.
Mack and Norm are correct. Start over with your shim stacks and be sure all shim stack are equal in thickness. IE dont have .035 in one center location and .025 in another.
if you buy a used clutch assembly, break it apart and measure all of your spring heights and disc thickness. if everything checks out ok you are only out a couple of hours. If not you saved yourself the hassle of putting it in the tractor and then having to split it back apart again ------------- Experience is a fancy name for past mistakes.

Knowing Mike there will be a ton of pictures, I'm counting on you to take lot's of pictures and making a nice case history on "The rebuilding of a power director"
 It might take some new parts and maybe not but knowing Mike, it will get the parts to make it right! we will have a ball making like new again! I need to get that 4020 back togather and open up that bay just for your D17.

Don, that video really helps. I guess my next step is make those measurements and see what I have. If I get it shimmed up correctly and it doesn't snap over sounds like I'll need to investigate the rollers. ------------- "Any man who thinks he can be happy and prosperous by letting the government take care of him better take a closer look at the American Indian."

Well the update is we drove the tractor around and it definitely holds like it should. Doesn't jump out of engagement, although it doesn't take much effort on the lever to go to neutral. I did tear the old clutch apart and the rollers and ramps are good. One of the friction discs is broken in 5 pieces and the lining is almost completely worn off. ------------- "Any man who thinks he can be happy and prosperous by letting the government take care of him better take a closer look at the American Indian."
