just finished taking apart the mount now, the second taper bearing has some play but not as bad as this one. Definitely an issue there.

When you clean the bearings you'll notice they all have play and dont actually move that smoothly until you repack them with grease. But yeah, your tapered bearing in the video had a lot of play and looked like zero grease! Dont just grease them, pack them with as much grease as will go in. Theres a method for that I'm sure you can find on youtube. Cheers

This after a few washes with hot water and soap, removed all the grease and dirt.

After this is after a first polish.

I'm happy with this result, might do another polish (maybe...)

With whatever I've found in the kitchen cabinet, used some Bio-mex surface cleaner and a cloth.
Nothing special there really.

I was debating today about the need of replacing the bearings within the brass dec/ra gear, they are metal sealed and therefore near impossible to open up and inspect.
One of the four was almost locked, it took me a bit of force to get it going.

Now, one of them is clearly not happy...

so, I will replace all of them with some SKF bearings.

Good idea to get all new bearings. Probably would do that if I did it again. But I'm pretty sure they come un-greased so you will have to pop the seal and pack with grease. Still popping the seal is easy, you just pry it open with a small screwdriver but careful not to cut the rubber - once again, youtube has the answer. A thin bit of rubber is keeping the seal on the bearing, its not a strong seal.

This is not a rubber sealed bearing, it's metal sealed...

There’s a metal ring with a rubber trim. At least it was like that for mine. If it’s all metal. I imagine it’s unserviceable.

I have now placed my bearings order... it's not cheap when you go with SKF bearings...
