Installing shims in the Level 10
If the carrier is not pushed all the way down into the power tube, the shims will get caught up in the threads where the power tube tip screws in. To prevent this, push the carrier all the way down (can use a pen or pencil), then with the power tube facing up, put in the shims. Make sure the shims are all the way down on the carrier (past the threads). Keep the power tube pointed up and install the power tube tip.
Removing Carriers Part II
Well, I didn't have a dental pick around so I used an old tent stake. The cheap metal ones that come with a two man tent and bend if you try to actually put them in the ground. They worked perfectly for pulling out the carrier.
Now if only I had a couple of scuba tanks to break the O-rings in on... I have gone through my 90-4500 twice now during this installation and just as I'm getting close, phhhhhhffffff.... Out of air again. Oh well, guess I'll be waiting until tomorrow to find out if I got it right this time...
Thanks for the help.
