Saddlebum is correct! When you screw a steel fastener into an Aluminum Case, the expansion/contraction of the steel is different than the Aluminum. I personally use a touch of Anti-Seize on the threads of the bolt to insure that the bolt can be removed later on. I believe that the cartridge filter is of a much better quality than a "Spin On" filter. Out of all of the Maintenance items on our Ventures, this filter will punish you the most if you get "Heavy Handed" during the install. FWIW, I have had really good luck drilling the head off of the bolt, removing the canister, and vice gripping the remaining remnant of the bolt out. Here again, if you get careless with the drill bit, (I always center drill the pilot hole first) you will not only destroy the bolt head, but also the canister as well. But there are NO special tools needed using this method. My brother is an electrical genius, but you can't let that boy tighten ANYTHING on a mechanical assembly! He has the "Paws" of a bear, and unless you NEVER want that fastener to come off again, I usually do the final assembly work, and leave the "Heavy Lifting" to him! Just sayin'.
