    For anybody else that runs into this problem, i had to pry the square shaft towards the inside of the machine and lightly tap on that ring with a brass hammer to get it to seat back down then while tightening the seal plate down also gave it a slight pry to get the plate to mate with the too of the case, i tightened to 25ftlbs i dont know if thats correct but thats what they were torqued to before i removed them

    Thanks so much, Willie59! This is a very well-done post and I all appreciate all the work you put into it.

    We have a 2019 T450 that has this same problem. I thought it had been fixed under warranty but turns out the operator never took it in... so I may be doing this soon. Hopefully, the T450 will be approximately the same. Thanks again!

    Thanks for a great tutorial! I've replaced the centering blocks and spools on my 773 and put everything back together. Machine is up on blocks and when I try to start it to make final neutral adjustments it makes a grinding noise and won't start. The centering bars contact the spools and the pintle arms are tight. The service manual says back the torsion bushings off so they can spin freely, maybe that's my problem? The odd time I can get it to run for about 3-5seconds before it starts the grinding noise and stalls. Any tips you could offer would be greatly appreciated. Just a farmer trying to save some $$$.

    That's because neutral is now out of adjustment from doing the repairs. Upon start up it's trying to drive with the parking brake engaged, which locks the parking brake because it's now under tension, you have to get that parking brake released so you can make the neutral adjustments by manipulating the sticks fore or aft slightly while cranking and releasing the brake. Only other option is to remove the parking brake locking plate until you make adjustment. Myself, I've always managed to get that brake released.

    Thank you for the response. I managed to get it released and neutral adjusted properly this afternoon. Next I need to figure out why none of the lights work.

    Fantastic info willie...much appreciated. Mine does this ever-so-slightly...not enough to bother me just yet. I have a neighbor that has a New Holland skidsteer that was creeping pretty profusely, and he fixed it with a piece of mechanics wire looped around the drive handle, attached to the side window panel to hold the stick in neutral, lololololol...:D

    LoL, as they say, necessity is the mother of invention. By far, my favorite that I've ever ran across was an old Bobcat 753 C series. Gas spring on the lap bar was dead. Easy enough, simply replace the gas spring, right? Nope, this customer rigged up an elaborate bungy system to support the lap bar. At first glance I shook my head a laughed, but once I used it in working on the machine, the damn setup worked absolutely perfect, just as good as the gas spring. I was impressed by the creative ingenuity.

    Hahaha, that's exactly right; necessity being the mother of invention.
    I'll be honest...my lap bar safety didn't work when I bought it, and the guy I got it from told me it didn't right up front, as the parking brake doesn't work either. (This 843 has the parking brake pedal on the floor between the loader foot controls.)
    The lap bar issue doesn't really bother me, because my machine was evidently built for an Ethiopian guy. I'm fairly "thick", and that bar made me inhale as hard as I could, get the bar down and then exhale and I was stuck there with no wiggle room...so I decided to bungee the bar up to the ceiling and not use it at all, lol. I do use the seat belt though, when I get into situations where I need the stability... which is very seldom.
    I only use my rig around my yard mostly anyways, for lifting pallets and occasionally to grade the driveway, it's not out on many jobs and I'm the only one that runs it, so it's a little different story than having 15 guys jumping in and out of it all day.
