Remove the rubber grip and there are three hidden screws, undo them and the lens hood and name ring assembly remove. No need to force things..... the front lens element set wasn't designed to be forced out!
Thanks for pointing that out Nigel. I was really struggling with that part. The forcing in and out of that section also damages the thread on both the internal and external lens holder section. Never seemed right to me that Pentax would design a lens that you had to force the elements out against the threads. As soon as I removed the lens rubber and the 3 tiny screws you mentioned it came apart easily and was very easy to remove the lens section.
Hi Tomoo Thank you for sharing this video but there is a part of it where you are showing how to remove the front element that is not the correct way to remove it. The part where you are forcing the front element out by twisting it and pulling it out is not correct. Please see below message from NigelR99 and my answer to his message. I think it would be good to update the video to show the correct way to remove the from elements. I made quite a mess of the threads on my lens following your instruction to force the font section out by twisting and pulling it out.

Hi there. Thanks for sharing. Your videos are wonderful. I have the same lens to clean but even with proper rubber lens tools I can seem to be able to get the front retaining ring to unscrew. Can you let me know how you removed the front lens retaining ring ?.
Thanks for sharing the video. I managed to clean mine today but the focus is off wide open, starts focusing by f8. Tried reassembly but no luck. Either I have not screwed the centre element properly or have put the centre element the wrong around. Not sure. Any ideas?
