"beat up" hardly looks broke in to me

Second that:yup
Do belive that you have many hours left on it.
And with the cost of a new in the back of your head you can fix it for some money and it still will be a good deal:IMO:exactly:IMO

So after loosening the master link bolts on both tracks and removing the trunnion arm bolts, exactly what speed do you have to get to before selecting reverse, to achieve the pictured result 
Good to see your not trying to work in a confined space :drinkup

Hey, don't laugh! We sat back and watched an apprentice and a so called journeyman lose a kitty off both of her rails when they were changing out tracks. We were having lunch up in the yard and looking down onto the grade below when they did it. None of us could believe they were actually doing what we thought, so since it was a nice clear shot down the grade ahead and they wouldn't answer the radio, we just sat back and laughed. They walked it to the end of the tracks, and as soon as the sprockets both disengaged the old set, she rolled right across the new set. That D9L rolled a good 300 feet down the grade before it dug in enough to stop. The poor apprentice in the cab almost messed his shorts since there was nothing he could do to stop. I mean really, what kind of fool undoes both tracks at the same time, especially without so much as tying it off to another machine.

Your "Workshop" brings back many old memories. Not too bad in nice weather but a real bitch when it's bad. We used to call it "field repair".....C ya........Ray

I wasn't there when they drove it off the tracks. They used a D 8 to pull the tracks farther back. This D 11 has had a new undercarriage and new engine a few years ago. I think it is approaching 18,000 hours on the clock. This machine runs 20 hours per day. The boss told me that the Z-Bar needs to be greased before we put this machine back together. Can someone please explain or show in a pic where the grease fittings are for that?:beatsme
I've never heard it called z bar before, but I assume you mean the hard bar, or equalizer bar.
If so, look on the top of the eyes at either end. There should be a plug on the top that comes out. Inside that plug, there should either be a fitting or threads for a fitting, that's where you grease. Bear in mind, it's been a few years and that was on D11Ns, but it should be the same.....or at least close.

the ends of the equalizer bar should take 80/90 weight oil not grease , you put grease it them when the seals wont hold oil.

Nice workshop.
Dont be driving machines off tracks. Bad idea.
Very easy way to change them out with the aid of a forktruck / Telehandler.
Gonna have to pull the frame to change the pivot shaft seal.

Yup Oil in the ends and grease in the middle. Should be a remote Nipple on the left side engine compartment.

There was a large bit of tounge in cheek when I made the post, I had spotted the marks where the tracks had been pulled back after she had been blocked up. BUT
I'm glad I did as the replys highlighted a point I had not considered. I've only ever once been remotely involved with changing the running gear on a dozer and that was a D8 in a workshop aged 19yrs old many years ago and the tracks were already off.
I wonder how many others had not considered brakes or lack off when driving off the end :Banghead :thumbsup
Well, not even the end, its when the track comes clear of the drive, which gives quite a way to clatter and ruin a pair of pants 'efore she stops

Hey Rob.
Dependant on the job. Changing tracks is easy if you do them one at a time with the blade and draft arms off.

How about the Ripper. Pretty good brake.

Ye, know what you mean Ross, trouble with spending so much time on machines that can slew 360, and have an arm & bucket on I tend to overlook some of the problems faced when pulling bits off other machines.
I wondered if the blade had been taken last, as the crane is still there. I expect the blade was used to raise the front for blocking?
In that scenario, stripping down, does it make much difference whether the blade or tracks come off first ? :drinkup

Yeah it looks as tho the blade was taken after the machine was blocked. We normally strip them without the blade and draft arms attached but we do have 100ton airjacks.
Well after 18'000 hrs then It will could do with a full rebuild (Dependant on work conditions)
Your looking at around $170'000-CAN for both frame's
Break this down to around $100k - $130k for parts and the rest is labour. Give or take it just depends on what crack's will be found and beleve me there will be some. If the tube is cracked then this is gonna take 4 days to repair.
I'am unsure what price for rollers, Idlers and tracks alone. I will have a gander tomorrow when I start my set's.

We did the undercarriage on one of our 10R's last year and I was told a good 400 000 went into her after we did chains, rollers, sprockets and yada yada yada.

Currently a D10R (Suncor) in for rebuild now. Quote $166'000 for the frames.
The whole rebuild is only running at about $330'000 but that is still rising.
Suncor Did supply quite a bit hardware like Tracks and roller's
Most Tar sand Customers supply hardware so I will take a walk tomorrow and see what a "Whole Nine-Yard" rebuild is running.
