I don't have a 350 manual or parts book, only a 1010. 1010 used a spring-loaded disk instead of the mess the 350s used. Can't you find someone that has a book if all you want is a blowup? Same setup was used from the 350 up to the 350Cs. As far as the facing goes, it's supposed to be bonded/glued to the isolator plate and is the wear surface where it contacts the flywheel and jerks around when the machine is being used. Not very durable. We threw out tons of perfectly good isolator plates because the lining had broken, or just plain fallen off. In retrospect, what a waste. But that happens sometimes when you work at a dealership. I asked my boss a few times about sending the plates out to get new linings bonded to them - but he didn't want to mess with it. If you're selling new parts and making a certain percentage, and they are warranteed from the Deere , there's little incentive to do anything else. I haven't checked lately, but if Deere insn't even selling the repair parts anymore, that's kind of alarming. Deere shows the newer unit as: "Torsional Isolator AT77319." I was just reading a report from the Department of Natural Resources in Michigan that blew me away. Relates to the John Deere "Certified Relife Program" for small crawlers. In certain places, they don't want crawlers any heavier than the 350-450 series, and found they can't buy new machines anymore (U.S. built, anyway). Seems the smalled Deere makes now is a 450 series that is much heavier than the old 450s. So, they made a deal with Deere to have their older 350 series crawlers (350 up to 400) factory updated and refurbished. Machines get repowered with newer engines, and all kinds of updated parts added. One thing I noticed is they all get the newer isolators like the 350Ds and 400s use. Price posted that Michigan is spending is something like $60,000 per machine. I almost flipped when I read it. I wish I could get the old parts that Deere is removing; wonder where they are going?
