Found a loose bearing on the front axle of our CAT70. Went to tighten the nut and found that someone has been into this before. The nut is very loose on the shaft threads. Decided to pull the stub and see what we can do...
Removed the 1" bolt and 5/8" bolt from the axle tube. Cleaned up all the grime from around the stub shaft and from the slit in the bottom of the axle tube. Knocked a couple of punches into the slit at the bottom of the tube to try to spread it open a bit. Put a couple more chisels between the axle stub shoulder and the axle tube.
Have been tapping on the axle tube and going at the axle stub shoulder with the air hammer to no avail.
Then cut a piece of tube to fit over the axle stub, a bit bigger than the shoulder, to bear against the end of the axle tube. Made a plate for the end and carefully threaded the axle nut back on. We have the nut fairly snug but don't want to over do it because the threads aren't the greatest (the whole reason for this operation!)
Any other ideas?
