D7 48A thoughts / opinions

sprockets look decent and they are segmental---measure the rail height at its thinness spot--looked a little worn--idler is worn but may get the 100 hours out of it.---on the power shift pull the filter and cut it open and look for metal particles---if you do buy use the Cat spec TO4 transmission oil

Track looks quite loose, check to see if there is any adjustment left to tighten them.

Hi mog5858, if the job you have lined up will come close to paying for the D7E it's worth a try. Don't be afraid of the powershift transmission, they are actually easier to rebuild than a direct drive. The first photo shows that the tracks are/were S.A.L.T.(Sealed And Lubricated Tracks) which means the tracks have a master link so the tracks can be removed by un-bolting the master link instead of having to press out a master pin. The tracks might have had a "dry" turn but they are still a plus. Overall the tractor looks good from the pics.
Beware: Once you get used to operating a powershift 'dozer you will be spoiled and will no longer be satisfied with a direct drive. I repeat, don't be afraid of the powershift transmission if you are capable of doing your own repairs. The trans and torque converter are not difficult to rebuild, just get a service manual and you will be amazed at how easy it is. :cool2:

I am working on getting a D7E back and running after sitting for 29 years. They are very well built machines! Did you speak with the owner? Ask him about the history of the dozer, this may help you make a decision. I would meet him in the morning and do a cold start. Run it for awhile and see how everything works when it warms up. You can do a lot of work with a D7 in 100 hours. Plus and more importantly, you might very find it enjoyable to own and operate! Best of Luck!
