Stabilize worn track

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Using the distance between four pins, this track is 100% worn.  The idler has been kicked out to the outside.  When the tractor is off level a little bit, the track disengages out of alignment from the bottom rollers.  I can lift the front of the tractor with the bucket and spin that track and it will usually go back on.  Last time it didn't, and came off to the inside.  I finally got it back on with critical help from a neighbor with a backhoe. The track is right where it finally popped back on.  The tightness in doing that seems to have locked everything straight.  From previous topics of mine the idler is cocked out and things are welded solid. 
I'm wondering if everything is straight in this circumstance to weld an angle iron to the base below the adjuster and to the adjuster to hopefully hold it straight.  If I could get another twenty hours without losing the track again it would be wonderful.  
I'd appreciate your thoughts!  Thanks!

	Any way you look at it, its a lot of work. First cut off that rusty adjuster, and bodge something up to act as an adjuster. Then back it off as far as possible. Now here's the part that will get me flamed, by the purists: chop a link out of the chain, if you have enough room, to slacken up, that much. Be prepared for fast drive sprocket wear! Then adjust it to proper tension, again. Aint purty, aint by the book, but it likely will get you a coupla hundred more hours... One other thing, count the links, and check how many should be there, before doing any chopping, to make sure someone hasn't done it before... Edited by DiyDave - 18 Jun 2020 at 6:01pm

	Bill is right you may get more info and patch ideas for your track(s) on the Construction and other equipment forum. Just my thoughts from looking at your pictures. From your photos your tracks/undercarriage appear to be well beyond 100% worn to me. The idler brackets are almost to the ends of the track frames. When you measured across the 4 pins to make your measurement, did you first put a big pin in the sprocket and power the track in reverse to make sure the track stretched really tight? (I was taught this is done with the machine on the ground. The way it sets in your photo is too loose to measure properly; from what I was taught.) The rail height looks below spec, the sprockets are worn and the bushings appear to have a lot of external wear. The way the inside right edge of the idler is rounded off it looks like it is out of alignment. Your adjuster(s) need repair so you can try to adjust the tension which may get you by for a while. My guess is if it was setting on the ground and driven forward a bit the sag measured along the top of the track(s) will be too much, which doesn't help in keeping it on. Yes, links can be removed but the tracks must be well beyond the 100% mark to do it. It is surprising as to how much difference the length of a link can make. If the tracks aren't worn enough you won't get it back together missing a link.

	the poor ol' gal surely needs a LOT of TLC.. To get 'just 20 hrs' of seat time, it might cost you 3-4 days for a 'bodge' with no guarentees.... makes me want to ask.. is it worth it ? while I like bodgin... spend 10 hrs and 1 hr later ,the track comes off, wouldn't be nice... spending another 3-4 hrs for a 2nd bodge and get maybe anothe 2hrs and man I'd be cursing the guy in the mirror..... if you only have 20 hrs of work for it, could you maybe rent/borrow a machine ? Any chance that's an option ?

	As for welding something on to hold it straight. The idler should move backwards when it hits something, that is the purpose of the spring behind the adjuster. If you want to try welding something to hold the idler straight it should allow that rearward movement.
