larger dies? for spindle - Pirate4x4.Com : 4x4 and Off-Road Forum

dharmabum · 05-30-2007, 08:06 AM

The threads on the end of the spindle of my junkyard Dana 44 are messed up by some jackass who crossthreaded the lock nut. Is it possible to get a 1 5/8"-16 die or is there any good way to clean up the threads? Its at the very end of the spindle so the nut should be past it when assembled and the rest of the spindle is in good shape so I dont really want to buy a new one as I can only find them in pairs and they are expensive (small bearing ones from 74-76 waggy). Any ideas?

Those could work, do you do it by hand or maybe put the spindle in a lathe going real slow and use them?

Personally, I would chuck the spindle up in a lathe, get everything lined up and set to the proper pitch, start in a "good" area of the threads and run it backwards to the end. Might do a pass or two like this and you should be good.

With the die, if you don't start in EXACTLY the same place cutting threads as was originally done, you will fawk up the rest of them too.

Just my $.02

You don't need a lathe to use the files.

What's the cost of a spindle vs. the price of a die that big?

I have a set of thread files, they are extremely useful. While rebuilding some of my older machine tools, I have run into large diameter threads that were screwed up several times. As long as they are a standard pitch, the thread files will always bring them back to useable. I would personaly just replace a D44 spindle, but some of the stuff I run into is not in production, or the parts are incredible expensive, so out come the files. One example is, when I disassembled my lathes head stock to reseal it, I found one of the threaded sections on the spindle completely f-ed up. Diameter was 2.25 IIRC with a thread pitch of 16, a new lathe spindle would have been in the $4k price range, and more than I spent on the machine. About 20 minutes with the 16 pitch file, and it was in good shape again. You can also restore 60* threads with a 60* triangular file and a lot of patience.

Later,
Jason
