No Problem Dave. I have searched through different forums extensively and got a lot of great suggestions from others as well. That's why we are here.

Before you drill, you may want to try others' suggestions i.e. vibrations, shakings etc to see if you can turn it to Position I (the Acc position), if you can, then you are saving yourself $$$ and time.

The "tool" that is mentioned in the schematic will cost you about USD 90 plus shipping but forget about it. I used a wrench with good grooves and a rubber grip mat that people use to open jars. Follow the instructions then you can replace the tumbler in < 5 minutes.

Good luck.
