Accessories: TEAC TZ-612 Hub Adapters - Cleanup.

With all my purchases, TEAC X-2000M, TEAC A-3440 and OLIMP MPK-005S-1, I also bought TEAC TZ-612 hub adapters. These hub adapters were always very hard to work with at the beginning, as because of their age, opening and closing was difficult and some amount of force was required. Pushing the adapters in and out became risky for the reel table locking system.
Below I am trying to explain a short and simple cleaning procedure in order to restore the hub functionality as it should be.

In the image below you can see the three screws that must be opened in order to completely dismantle the adapter:

Then, the hub can be completely separated in all the pieces:

Now, if you look closely in the pictures below, you can see some PVC dust accumulated in time as a consequence of regular operation (friction between parts) and also some dry lubrication grease:

I have used isopropyl alcohol to clean all the parts.
All the parts were assembled together at the end, the result is a hub operating normally, no more force to close it or open it.
