It aint been gettin worked hard..that things probly like new…i hadnt run a john deere in them year models but they made an make a fine machine..average to low hours kn a machine that old would probly be in the 3-6k hr range…an its hgot hours like that then the pads at the least are probly wore good id guess an the grousers are probly about flat..if it aint then its probly been replaced…in my experience runnin in chirt or anything sandy..you get about 3000hrs out of a set of pads an the chakn may need alot of work or more than likely completely replaced…once you get to rockin around the 5-7k hour range…id suspect the entire undercarriage is going to need to be completely overhauled…new sproket,rollers,idler tensioner..and chain an pads again…some more..some less..an it depends on what you run the machine in and what you are usin it for also…we had a d3 that had to be completely re worked at about 4500hrs because it was gettin worked to absolute death about 6 days a week it got dang near 3k hours out in it in a years time..thats smokin one in my experience..the sproket teeth were so worn it wouldn’t hard catch the pins..barely would move.


3,000 hours a year is flat out keeping the tracks clicking!


If my math is right that’s almost 8.5 hours a day 365 days

Your math is fine..if it was 8.5 hrs a day…that dozer got ran id say🧐10-14 hrs at least 5 days a week pushin coleche and others base materials buildin roads and an insane amount of work on the ranch i worked onin south texas an gettin run in nearly pure sand…disclaimer…i was not the one runnin it..little mexican preacher ran it an a big d7 with rippers. They built a 25 acre lake for us and it took probly 6mo to finally clear and completely re shape 135 acres or so along with stock piling i think around 400k yards of material..my memory may be failing on that..it has been quiet awhile…when the company we hired to do it won our contract they bought brand new equipment to do just our project…the amount of material they moved was stupid an they ran 3 pan scrapers for i have no idea how long everyday…i know the top of the dam was something like75 ft wide an the base all the way around was wide..i mean..i cant remember the exact number but i bet the bottom of the dam was 300ft wide… we had a 10in ductile iron main ran to the center and its origin was about a mile away where we had a 250hp well installed. I think it took them and the company that laid the liner about 18months to finally complete the job. I dont think it had a full 3k hrs..probly more like 2700..but it was an insane amount..an i saw that machine runnin more than not…i do remember when they brought it there an unloaded it..it had plastic on the seat..after it was over..i dont think it even still had the hoods on it over the motor an about all the windows was knocked out from runin in mesquite motts…i promise you..it got beat to absolute death..but i dont rekin it ever had any engine trouble. I know they had some older cat dozers they would do inframes on in the winter…they said they could get 16k hours out most of the older cats before they had to do a rebuild..i know they had a mid 90’s model d7🤔 i think..it had a little over 24k hours on it but it was on its second rebuild an ready for another.
