Alright everyone, progress update. Got the crawler running again, moved around, and decided its time for phase 2. Today was tear down on right side. At least I had an idea of how to do the tear down and the order.
1. I saw black grease around all the track rollers. This is indicating a tear down clean out is definitely needed. The rollers rolled fairly smoothly with no wobble. I might not need shafts. Probably going to need bushings though. I will assess when I get them tore out.

I cleaned everything off the best I could, and soaked all the roller studs, and nuts in free all for disassembly next week. Ill probably hit it with free all again through the week on and off in preperation.

The idler i noticed once I got it off was pretty wobbly. So that means I will have to tear it down and replace bearings and races most likely. Unfortunately my manual doesn't have the internals or a picture of the breakdown of the wheel section, just the support break down. So once I get it tore apart im sure I'll figure it out.

The final drives weren't looking too bad on the outside. There was only some slight wearing on the sprocket from the bolts. It doesn't appear i have any stripped pulled out bolts like the other side. The pinion cover also looks pretty good. I did however look as closely as I could and it appeared the track frame shaft had broken welds on the back side of the final drive assembly. Once I get the final tore apart I will be able to assess better. I did however notice that wonderful silicone gasket remnants that was used around it. Most likely not much oil inside the drive. I again sprayed free all around all the bolts in preparation. To tear apart.

Sorry it didn't upload right. On last post

So also, the sprocket on the right side has a huge chunk out of it. The way it looks is they cut it to get access to the pinion gear cover. Not cool. Anyway, I'll be going up to Ephrata to see Landis to see if I can get a replacement. I'm not going to use it because it would be really easy for something to get jammed in their while moving and tear it up.

Also here is a photo of the assembly off the crawler. I also got the new alternator on previously. Seems like my gauge is garbage. The wire tested with my simple bulb indicator all the way up to going in, but nothing out of the ammeter.

 

[crowsnest2002]

Also, lug nuts were a mix match of something else. My OCD might get the better of me and I'll get all the correct ones. The others are longer and nut flush with the lug.

Very neat, and mostly like mine. Mine has the flat pads, low-wide grossers. Still gets good traction. Heavy- SAE 140 gear oil- best in final drives. Track pins and bushings OK?. Sprocket teeth in first photo look a bit sharp- lots of wear if slack or worn track rides up. keep hyd oil clean and dry and brake bands adjusted fairly tight and enjoy. If sat outside, also check that no water in trans.

Eric,
looks like it mostly sat inside when not in use. Ive been replacing everything per service manual with the exception of the John deere corn head grease in the rollers. I haven't gotten to changing transmission yet. Ive been mostly consumed with trying to make sure final drives are in order so I dont break it worse lol. After the oil plug issue, it looked like it was a very long time since it had an oil change. I should do transmission next though as a side job. I have the oil already.

Idler rebuilds as track rollers. Your fight, but I doubt you need to tear down "wheel section" for more than cosmetic reasons. You are probably good at fixing the guts by now-same stuff. Enjoy!

If its same as rollers, easy peasy. (Famous last words). I think I might have left over shafts after doing the rollers on the right side but we will see. They all seemed pretty decent once I got that side flipped upside down. The only problem is im subject to the elements while working outside, and it gets dark at 5. Thanks for the tip.

Question time for anyone capable of answering. See attached wiring diagram. This has positive ground. I get that. But mine has the ground running all the way down to starter bolt at the dip stick. Should I shorten the ground, or leave it at starter? Seems like an excessive amount of wire to ground at the starter. Ive always thought shorter wires for batteries is better. (Less loss) i am probably going to redo the wires anyway, because some of them look like they got a little hot a few times.

 

[Ericp351]

Your call, regarding wire. That said- earth to starter is an excellent way. I think I put mine to a rear head bolt last head pull. Just go O or double O and send it. Ain't no rule you can't add a stubby 8 or 10 gauge to dash pannel, et cetera.

Thank you sir. Actually moving it 50 yards gave me a smidgen of motivation again to tackle that other side.

Did you have to use a special press setup to get the track pins apart? Awesome pictures and awesome project. Keep up the good work. Just to think about those engineers, machine producers never dreamed these machines would be operating in......the future!

No sir, there is a master link / pin i believe its called. A pin with holes drilled on both sides with cotter pins that go through, and the track has recesses for the cotter pin. Just crib up the crawler, start it, rotate tracks to desired break point, knock pin out. I will try to get a picture tonight for reference. Hopefully it wont be too dark when I get home.

 

[crowsnest2002]

Also, reached out to a person on ebay for an ammeter new old stock with box. They will be testing and measuring to confirm. Im thinking I might be better off with new old stock vs the plastic counterparts available out there. Plus if its tested, it might be better than the Amazon gamble from China.

 

[crowsnest2002]

Please see attached track and pin for reference.

Was looking at the photo where the wear was occurring on the rollers from track .
Please photo the other side if possible when you get there.

 

[crowsnest2002]

Ill try to maybe snap some photos again. I was out earlier working on the right side rollers this morning, but the wife is dragging me away from the project. You know how it is. I really didn't get some pics of disasse.bly of the left side. Mainly cause its grease fest and not an appropriate time to take pics. Ill take some pictures when I get to that last roller. All shafts and rollers full of black grease,and on the verge of becoming a somewhat solid mass in each roller. I only got 2 completed. So far all brass bushings have been good, and replaced 1 shaft because I thought it had a little more wear than I wanted.

 

[joeysmith]

have very little mechanic knowledge

Yea I know mechanics that wouldn't of tackled all this
Nice work an keep us posted
