    Gotta say Chris one heck of a Parade piece. Its nice that it lives on! Kudos for putting a new heart in it! The kids must go wild over it, yea dads too I bet. Nice conversation piece at a show. Just needs a trailer for the folks to ride on. I'll wager the local farmers have you on speed dial! Anyhow I love a smooth ride at my age and my old Buick LeSaber has those nice tall side walls. Makes you feel like your still on the couch at home.
    I was wondering are yours made to be high flotation if you reduce the air pressure?

    Ready for the big reveal, we will soon see what mechanical mayhem has been going on inside.
    Excessive play in both sprocket hubs and when I look inside through the filler hole the big reduction gear moves the same amount as the sprocket hub. Plenty of sparkles in the oil when I drained both final drives but no chunks of metal so fingers crossed
    More pics to follow at weekend

    Safest way for DIY removal is OxAxe the coils until all tension is gone, then take it apart

    Both sides pulled down today, top pinions are ok which is a relief. Has had previous surgery prior to my ownership. The smaller intermediate gear and matching bull gear are complete toast. Both sides require new main bearings and seals.
    Not as bad as it could have been !

    Looks like that bearing sat in a water puddle for awhile. Reminds me I need to give my 977L a Spring oil covering engine heating run back and forth. That machine needs rails/tracks soo bad I'm afraid to turn it.
    Keep up the great work on the disassembly pictures!

    One missed point is it did not grenade, had the teeth sheared could have destroyed a lot more

    Looks like someone has been in here with the welder before. Hub and bull gear will make a good table

    Most likely welded inside the last bearing race to make removal easier.

    Not much to to report, awaiting some bearings and seals that were not available in stock. Have had a bit of luck though, the place where the hub came from had a bull gear hiding in the store room so had that also. Saved a lot of searching !
    Soon be ready for another visit from “The Firm” to get it all built up correctly.
    Cheers Chris.

    Clean casings, and some bits in the freezer. One of the new bearings mounted on the hub too, small amount of progress but heading in the right direction I hope.
    Cheers Chris.

    A visit from The Firm today and some fair progress, just need some sprocket segments. Seem to be thin on the ground here, 3 - 5 week wait from one supplier.

    Final drives filled with oil, transmission magnetic screen cleaned out, filter swapped and transmission filled with oil too.
    On to removing the studs now, welded some hefty nuts onto the studs and got at them with the inch drive impact gun.
    Feels like I am heading in the right direction now
    Thanks must go to @tctractors for all the work, advice and help so far, cheers Tony
    Chris.

    Excellent pictures Chris! The resolution is the best I've seen. Looks like the machines sat in some pretty damp places. Petty flaky corrosion. Too bad it's such an excellent machine. All the nice extras on that one. I'm still Jealous!
    Best of Luck

    Thanks Shawn, yes I agree with you about the corrosion, I guess working most of its life in forestry and lack of cleaning / maintenance has taken its toll.
