So for 2 weeks daily I worked on pulling the bearing carrier out of my 82 J75TLCNB. This thing would absolutely not budge after using: heat, various penetrants, pullers (home made & gear), rubber mallets, ball peen hammers, all of them at the same time... but nothing worked.:frusty: The next step was attempting to crack the bearing carrier into pieces or a stick of dynamite.
Then, I had one of my fairly dangerous "brilliant ideas":facepalm:. I thought I would try moving this from a different direction (sort of). I'm sure I'm not the first to do this but perhaps the first to document it. If its out there already, my apologies.
FAIR WARNING...THIS WAS NOT THE SAFEST DESIGN :doh: and should probably only be used after everything else has failed. In other words...as a last resort!
I got the following items:
* 2 ton bottle jack (because they are slim and short)
* small section of fairly heavy chain 2.5'
* two 3" x 5/16" threaded eye bolts
* two threaded quick links
* and a small rectangular piece of flat stock (2" x 4" x 1/2").
I screwed the castle nut flush with the end of the prop shaft and hooked the system up.
Once set up (jack piston straight in line with the prop shaft) I put mild tension on the system to take up slack in the chain. I made a few final tweaks to straighten everything (very important) and proceeded to pump the jack until it wouldn't move any more. At this point the carrier still didn't pop, but that had been my luck so far anyway so I wasn't very surprised (more amazed really).
So now the system is pretty much under almost 2 tons of load (I'm assuming because it was maxed out) and its still absolutely frozen. I then fire up the propane torch and start hitting the areas where the carrier is pressed against the walls of the housing and to my surprise....POP! The carrier moved about an 1/8"! I hit the jack with a few more pumps and out she came! VICTORY WAS MINE :first: (although short lived). See my other post about the internal retainer clip!
Now in no way am I recommending that anyone try this at home. However, I lived to tell about it, so....play at your own risk! If you do try it...please be "safe", take precautions eep: and please make sure there are no kids around! There were lots of things that could have gone terribly wrong with this setup but I am 100% certain it could be made much safer if you put some effort into it.
If you try it...MAKE SURE EVERYTHING IS LINED UP PROPERLY BEFORE YOU BEGIN WITH THE FINAL TENSION STAGE! Mainly the prop shaft and the jack piston.
Here's a diagram of my contraption as I didn't even think to take pictures at the time.
