It shows in the parts book (if you have the right book, e.g. Parts Catalog PC-727). Early or late 1010 was available with a mechanical adjuster or a hydraulic adjuster. I suppose you've got the first model with the gearshift coming oout of the dashboard? The mechanical aduster is just a threaded bolt and is adjusted with a crows-foot wrench. Probably a carry over from the 440 crawler. Hydraulic adjuster assembly went through a lot of changes, so you never know for sure what you have unless you pull it apart first- regardless of serial number. As far as the grease fitting goes, a lot of people dumped the buttonhead fitting and stuck in a conventional grease fitting. Only possible problem with a conventional fitting is it's a better target for brush or rocks and can get broken a little easier. When the machine was new, Deere used buttonhead fittings on all the undercarriage (idler, adjuster, and rollers). Most new rollers are no longer greasable and ride in oil instead. On the hydraulic adjsuter, the seal on the piston can vary. First style, up to #42,000 was a leather cup. Worked pretty good and is still available as part # T11123. It utilizes a removable cap that is bolted on, but sometimes the bolt worked loose. Then Deere went to a square sided o-ring #AT13014. Far as I'm concerned, it was worthless. As soon as the adjuster cylinder gets worn, the adjuster keeps leaking down. When I worked in a Deere repair shop, standard procedure was - if we found any crawlers that had this sytle of adjuster seal - we'd pull the piston out, and machine the groove to accept the newer style seal that is used in later 350 and 450 crawlers. I don't have the parts book, but if you look up the adjuster seal for a 350C crawler, you'll find the right one. It's almost indestructible, and will usually work in highly worn cylinders.
