I have a 455. 2wd. industrial with back hoe and loader. The front end needs some work. I got the steering cylinders apart currently looking fr seals and a piece of 20mm hydraulic rood to replacec the one that is bent.
This post is in regard to removing the king pins in order to replace the bushings and thrust bearing, The bushings are totally worn away, I am hoping the spindle castings are not hurt too badly. The thrust bearings are completely gone. Needless to say it does not steer very well. I got the tapered pin sout without too much trouble. Lots of PB Blaster and my small pneumatic hammer pushed them right out.
The king pins are altogether a different situation. 3-4 good hits with a 5 pound sledge did not even budge the pins. This tractor has spent the last 10-15 years primarily doing commercial snow removal. There has been lots of exposure to salt and moisture. After the season it would just sit for nine months. I actually got it for free, when the guy gave up his snow removal business, and no one wanted the rusty tractor.
I am thinking i need to heat the axle and force the pin out. I have no way to get this ti a press, short of removing the whole axle. I have a 20 ton hydraulic jack. Does it make sense to put the jack under the pin to push up, and chain the axle down to the jack? Then heat the axle and try to jack the pin out? Does the pin come out the top or the bottom, or does it matter?
I cannot work on this for a few days so I am trying to think of the best way to proceed.
Any suggestions are appreciated.
