Bearing carrier shock tube install day. What a process and massive effort! Not for the faint of heart and you better have the right tools otherwise forget doing this.
After reading everything I could about this subject and getting lots of great advise from this forum here is what we did (Drew came over to help as you need two people to do this effectively).
1) put the shock tubes in the freezer overnight
2) Preheat your propane gas grill to 500 degrees F. Put your bearing carrier in the grill, close the top and come back 20 minutes later.
3) Have a metal pipe to carry your very hot bearing carrier to your hydraulic press. (You have already set up the press for a 24 inch space to press). You need heavy leather welding gloves to move the bearing carrier around. Remove the shock tube from the freezer. Oil the inside of the bearing carrier. Insert the shock tube and press the tube into the carrier.
If you do this quickly it will press through the first part easily. The second part of the carrier takes more time (the tube has gotten warm, but it will press through)
Make sure you have screwed the shock retaining plate into the top of the tube before you start pressing.
