Last time I drove the D17, it has been getting increasingly noisy in the left final drive. When it started chirping (drive is full of lube), I figured it was time to fix it. I don't have one of those dandy little tools that pulls the pin, seems like it's made by one of the guys witht the the show in Hutchinson, so I improvised. A 3/8 bolt welded to the head of the pin, a nut, washer, and a deep well socket pulled it right out.

The bad news is the drum is cracked down to the hub. Getting the old one off is no problem. I'll just cut it most of the way to the shaft and crack it the rest of the way with a blunt chisel. I don't see any snap rings or set screws so I'm guessing they are just pressed on? Any suggestions for installing the replacement? I'm thinking I'll clean the replacement and set it in the oven for a 1/2 hr on 300 degrees so it heats evenly, less likely to crack, and it should drive on fairly easily.

That's what I did on my 45 diesel when I changed out the brake drum. I heated the drum up first, and then I also had a piece of pipe cut nice and true and long enough that just fit over the axle. It slid on easy at first but as I worked it down and the axle heated up from the heat transfer, I had to use the piece of pipe to get it the rest of the way down.

Thats the way my nephew and I did are D 17. Its good to have someone else around to grab the drum and slide it on when you get it hot.
