I have to replace the front axle U joints on my Case 580SM that I use on my farm. I have a a couple of questions on doing this repair.
1. If I remove the upper and lower king pins and the tie rod end from the Planetary drive / Hub assembly can the entire assembly be removed from the axle
housing and the axle/Ujoint assembly pulled out of the back of the hub or is there a snap ring or other type of retaining clip inside the planetary drive that
must be removed before the axle/Ujoint assembly can be pulled out ?
2. I removed the 4 bolts holding the upper and lower king pins today to see if there will be a problem getting them out. I was able to rotate the upper king pin
and pry it up slightly so it looks like that one will come out fairly easy. I was not able to rotate or pry the lower king pin out of the bore although I didnt
use a lot of force yet. What is the best way to get a stuck king pin loose ? Is it OK to use some heat or is it too close to the bearings ? I thought about
cutting a small notch at the joint between the king pin flange and the housing with a 1/16 disk on a mini grinder so I can drive a small chisel in the notch to
try and break it loose.
Appreciate any other suggestions on getting a stuck king pin loose.
