Went to Cat yesterday and bought the frictions and steels for the brakes plus two 5 gallon pails of oil. $800

The Service brakes and park brakes are the same. Just linkage operated. Got the axle back together and in the Hoe last night. After talking to the other mechanic it turns out some of the operators wont put the tractor in low gear when coming off the mountain so they are forced to ride the brakes for several miles in steep terrain.
I forgot to take my camera to work yesterday. I'll post some pics tomorrow. These guys can tear up anything.
We have two 7.3L powerstroke diesels that are ****ed because they drove with the airfilter boot disconnected and ingested massive amounts of dust. In one of these engines you can rock the pistons in the bore and hear them click as they hit the other side of the bore.
