Hello everybody, just a heads up, this is my first post, so I hope I‘m not doing anything wrong. I recently bought a ts55 rebq in quite bad condition, however it was working, so I thought why not . Having opened it up completely, there have been some problems. It was used to cut a lot of drywall without any dust extraction, so every single part was covered in dust and I‘m still trying to remove it. If you have any tips on getting the stuff thats really caked on off I would thank you very much. I‘ve tried hot water, dish soap and even putting it in the dishwasher, however nothing has worked so far, except scratching like a maniac.
1. I want to replace the lube from the gears. Do you have any recommendations/things I need to look for when buying new lube?

2. After some research I think I broke this part, however I‘m not sure which part it is. On the drawings, It looks like it is part 721509, however I‘m not sure. Can you tell me if this is the right part or if I even broke it in the first place.
I look forward to your help and will probably keep you posted on my real first project. I hope I didn‘t miss anything, however if you need more information please ask.
