If you are pulling a allis 7000 do you remove the 1 2 3 power shift out of the transmission if you are pulling in light limited super stock. If so how is it done Thank you for the help in advance |

| Light-Limited-Super Stock to me means over 1,000 HP, so yes, that clutch must go. A coupler needs to be fabricated to connect to whichever range you want...under drive-direct drive or overdrive. Approx 20% jump between each range. |

| Always heard the 7000 was a one of a kind with the Powershift setup it had- and they were based on a 200 tractor- so the powershift can be removed , interesting |

| All original Power Director tractors that were hydraulically activated were two-speeds, direct-drive (high) and 20% under-drive (low). The model 7000 tractor had a 20% over-drive added to the concept. The whole torque housing is completely different with this new design and the PTO is fully independent and 540/1000 RPM only. Amazingly, the length of the torque tube is still 39 inches, the same as previous models (180-185-190-200). |

Hey Doc , ever do any comparison with the gears between the 180 / 200 vs the 7000 as to a retrofit ? I noticed the 7000 do not use the bushings on the pinion... ------------- When told "it's not the money,it's the principle", remember, it's always the money.. |

| You know, it's been since 1977 that I had my first maroon 7000 transmission apart. It had a bad pinion seal transferring oil one way or the other. I had my second one apart in the early 90's for reverse gear on the counter shaft having the teeth all chewed up from a heat treat issue. They have been that good !! Two 7000 transmissions in 40 plus years !! So, no I did not compare parts to the 180-200 transmissions, but I know the gears are all wider and I'm thinking the inner diameters may be larger too. The width would be the deal breaker in the end I think. |

| We are lost at the transmission. How did you build the transmission to hold up to the power? |

| I have no idea what JM hall is trying to do, but I am used to LLSS tractors running road gear, which is direct drive. If you want to go faster than that, then you are getting into the custom gear making area. A true model 7000 drive line would have room for an over-drive box right under your feet where the Power Shift clutch assembly was. Road gear in the tranny with an overdrive speed-up ahead of it. |

| Power through trans. is no problem, gears will hold. Weakest point is ring gear moving away from pinion. This can easily be fixed by a girdle around right bearing housing and reinforce out side of bearing housing. MACK |
