Help Inspecting Undercarriage - 977H

[bulletpruf]

New undercarriage shouldn't be a problem but the cost would be. I'd guess well North of $10K for a 977 and maybe as much as $20K if everything is needed and it kind of looks like that. Maybe could find some decent used tracks. In the mean time you could run it as is. Just be prepared for the tracks to come off.

That's kind of what I figured - something north of $10k. Thanks

Were popular machines check machinery trader find a dismantle parts tractor. Track pads can be rebuilt with grouser bar & a good welder. Watch video started nice & crawled on and off lowboy with no problem sure looks like a good ol' 977 not destroyed doing demo work

Thanks for that input. I really appreciate it.

I see that thing as sort of a glorified yard machine. get it moving and turning, then use it to pick up a heavy thing now and again and it is worth the $1800 move. If kept on flat ground and not in a hard push, the tracks will probably hold up. It is one sidehill away from a very bad day so I would use it how it is on flat ground.
Spud has one that he rigged up a boom on. Stuff like that.

There’s one thing running a dozer on an undercarriage as worn as the 977,and another thing running a traxcavator on those old tracks.
I would think spragging with a full bucket would rip things off very quickly on that machine

Um, what is spragging?

A full-on turn by locking one track on the brake and powering the other. AFAIK used since Year Dot when referring to steering a crawler crane.
Fortunately, bearing in mind the condition of the undercarriage on this particular 977H, the powertrain is not capable of counter-rotating the tracks. That would be a recipe for disaster.

Sorry,it’s a hard turn after locking one track up as Nige explained.
Looking at the rollers on this machine,I’d say it would be very easy for the rail to run off the roller flanges and probably snap when turning with a loaded bucket
