Terex Dozers

I am thinking of buying one,and know they are getting harder and harder to find,I am looking for a 82-40 DA or a 82-50 anyone out there who has ran them have any opinions of them both good and bad ,I know the allison trannys were pretty reliable and parts for them can still be had.how do they stack up against cat machines .I would love to hear from some operators who have had some time on them .Thanks.

Those are pretty big machines, and will be hard to find. I do not have an answer for you. Someone else here will most likely. However, there is a very good site on Facebook that deals with all Euclid and Terex equipment. The group is called "Terex and Euclid Equipment". Check it out.

RZucker can give you some insight. I would like to have one too just for fun, but not planning on it the near future. There are always between four and several on Machinery Trader at any given point.

No expert here, but I have worked on a handful of 82-40s and a few 82-30s. Got to play with an 82-50 for a few hours too. The 2 stroke Detroits and Allison transmissions still have available parts, the FCB steering clutch/brake units use Allison parts too.
Undercarriage is where stuff could get tough, I haven't looked for quite a while but there may be some aftermarket parts available now.
I rented an 82-40 to push fill across a swamp once, very fast machine, it out produced an old D9G that we had been using but was too heavy when the wet sand started to get loose and sloppy.
The 82-50 would have made a great scraper pusher if it had a cush blade instead of a U blade. It was faster than the D9 too.

Have heard they were a little nose heavy. A few years ago saw a nice 82-50 with good undercarriage sell for 16K at auction. Blade cylinder creeped a little but looked like it was well maintained.

They were very popular in their day but parts could be a problem not so much for engine and transmission but track rollers were running tapered roller bearings, and had a different mounting system to everyone else, they also had a Nitrogen cylinder in their track recoil system instead of a spring which most others had, parts could be hard to find in those areas. I have done a bit of time on 82 30 & 82 40 and they performed well, biggest difference to get used to is the fact that the radiator is behind you and visibility to the rippers is probably not as good as some.
