Sigh, motor grader. How hard to change the axle and bearing?

Found this near me:

Price is right, but needs an axle and bearing replaced. I'm handy, and have some small tractor experience. The big question is about getting the parts.

I presume it will need the axle, bearing, seal. Might have to work in place if the unit can't even be moved into a shed. That would complicate things.

So, where can I get parts from a salvage/new supplier? How many hours to get it apart, and replace the bits? I wonder if the trans/diff needs to be opened?
 
That shiny new cotter pin says to me
that someone had it apart already, if it
was just bearings why didn't they put
them in to sell it? Bearings should be
readily available but I'm curious if
they found a damaged housing or shaft as
well? Allis Chalmers construction parts
can be difficult to get, likely have to
find salvage or repair what you have.
Still could be a good deal but don't pay
too much for it
 
OK, now for the REST of the story from the seller. He runs a small dirt oval race track and they've been grading it for years. All left turns. All with low tire pressure. So, it appears that the chain case housing is fretted and cracked from all that tight left turning.

So - that means it's got to be taken down to the diff flange, and figure out what's bent in there, and get it straight, then put it all back together. He didn't leave it so long that the chain box inner flange snapped, but about all it will do is load on a lowboy. He said rest of machine is running well, and very few leaks. Doubt it is worth it, but once I find out how much to rebuild the chain box(maybe both sides), I'll know a bit more.
 
He's off a bit on his weight I'd say. Maybe
25,000-30,000, but not 25-30 tons. I had a
118 Galion that was a good bit more solid
built, and with the scarifier, but minus the
engine, it weighed 29,500. Even though the
listed weight for it in all the books was
24,000. I'd say it probably wouldn't be a
hard fix, maybe time consuming though, but
that's me, and I used to do that stuff for
living. I think he should take that into
account in his price, I'd say $2500 MAX
needing a repair like that, maybe even
$2000. I could see that if it had a cracked
front axle or something like that to fix,
but that's a bit more major.

Yeah, thanks Boots, I figured the weight was goofy. He said 'make me an offer' as he just wants it to disappear. I'm sure it would leave his place for $2k. It was good to know that he was using it every Friday and Sat to grade the track when he stopped using it. He's got another grader already working, so it's just sitting there. I'm gonna go up and have a look in a few days, and see what we will see. Guessing the repair labor will surely go another $2000 or more, but then I'll have a grader that will actually grade decently. It could use a new or re-profiled blade as it's kinda curved in the middle, just more money there.

The Detroit Diesel will go forever and leak appropriately. Wish it had the turbo, but it is what it is.
 
If it were close, and I needed one again,
I'd have no qualms about buying one like
that again. My Galion had an IH 554 gas
start diesel 6 cyl in it. It was a real nice
grader, but cracked a head, and wasn't worth
trying to find another head. Mine was also
used to scrape a speedway racetrack. I sold
the engine for parts to a guy from Utah, who
came to MI to get it, but I kept the
injection pump. Scrapped the rest, got a
premium because of the thick iron in it. Got
$3000 scrap out of it about 5 years ago. Not
bad for trading an $800 real clean Oliver 77
and $1000 for it.
