| Can someone list all the seal numbers and quantities I'll need to reseal the PD. I need to put another spring in the torque limiter and want to reseal the PD while its apart. |

Go to the AGCO parts book for that tractor, and order ALL parts with the description of O-Ring, or Seal. Should be page 158. Do NOT order item 70267399, SLEEVE, Seal, unless you really really need it, very costly, and unlikely to be needed. ------------- Still in use: HD7 WC C CA WD 2-WD45 WD45LP WD45D D14 3-D17 D17LP 2-D19D D19LP 190XTD 190XTLP 720 D21 220 7020 7030 7040 7045 3-7060 Projects: 3-U UC 2-G 2-B 2-C CA 7-WC RC WDLP WF D14 D21 210 7045 N7 |

| I looked them up at lunch,glad you said something about the sleeve cause I was going to order it. This will be my first time tearing into a PD so I'm hoping it goes smoothly. |

Word of advice if this is your first one, you need to use generous amounts of hydraulic fluid when assembling the clutch pistons, AND a couple of feeler gauges, to "slip" the piston seals in the housing. They are very easy to damage if you aren't careful. If you tear one even a tiny bit, replace it. ------------- Still in use: HD7 WC C CA WD 2-WD45 WD45LP WD45D D14 3-D17 D17LP 2-D19D D19LP 190XTD 190XTLP 720 D21 220 7020 7030 7040 7045 3-7060 Projects: 3-U UC 2-G 2-B 2-C CA 7-WC RC WDLP WF D14 D21 210 7045 N7 |

| One part number for a "seal kit" gets you every single seal. |

| Thanks for the info. So does the kit also include that sleeve deal? Any idea on price? |

You will have a few extra seals in kit. Sleeve does not come in kit. Why do you need another wrong in torque liminator? MACK |

| There isn't a seal kit for the 100 series tractors. Just order the individual parts for them. I usually replace the three steel sealing rings in the 7000 and 8000 series along with the seal kit. |

I think a new torque limiter will slip some at the very first until it burnishes itself in....... key words "I think". ------------- -- --- .... .- -- -- .- -.. / .-- .- ... / .- / -- ..- .-. -.. . .-. .. -. --. / -.-. .... .. .-.. -.. / .-. .- .--. .. ... - Wink I am a Russian Bot |

Are you still running the old pressure plate setup, or has it been upgraded to the beleville washer ------------- Still in use: HD7 WC C CA WD 2-WD45 WD45LP WD45D D14 3-D17 D17LP 2-D19D D19LP 190XTD 190XTLP 720 D21 220 7020 7030 7040 7045 3-7060 Projects: 3-U UC 2-G 2-B 2-C CA 7-WC RC WDLP WF D14 D21 210 7045 N7 |

I'm getting my 7040 PD ready to put the beefed up tq limiter back together. My plan is to use the new hd 6 pad disc, the new pressure plate, and a new belleville washer, and add the old belleville too along with some CAT 5P8245 flat washers (.125") under the stands to keep the bellville (.160") washers from going over center. This is not going to be a dedicated puller, but will be hooked to a sled most of the time. I really don't want to bolt it in solid, so to speak. I plan to make a clutch aligning too to center it, since it probably won't slip enough to center it. I won't be pulling this in road gear lol! ------------- 210 "too hot to farm" puller, part of the "insane pumpkin posse".

We are going to drill and tap the flywheel surface for six 1/2" allen headed bolts, and turn down the heads thinner, so they will fit in the 6 round holes in the slots of the disc. ------------- 210 "too hot to farm" puller, part of the "insane pumpkin posse".

Good to know, I just always assumed the ones I have split had already been upgraded. ------------- Still in use: HD7 WC C CA WD 2-WD45 WD45LP WD45D D14 3-D17 D17LP 2-D19D D19LP 190XTD 190XTLP 720 D21 220 7020 7030 7040 7045 3-7060 Projects: 3-U UC 2-G 2-B 2-C CA 7-WC RC WDLP WF D14 D21 210 7045 N7 |
