One of my Verdes has the original oil-fed tensioner which still works well. The other one has a new-fangled mechanical tensioner.

The hydraulic tensioner does appear to be much stronger and I think it puts more tension on the timing belt. When I switched over, I used gasket sealant on the oil plug so it probably will not be that hard for me to switch back - that is, if I can find a good replacement bearing!

Bob I pressed out that different center eccentric piece on both 24v and 12v bearings no problem.

The inner bearing ring is covered by the top side of the eccentric piece on one side. To press the center piece out, one has to support the bearing at the outer ring. But by doing this, it will put pressure on the balls inside that will in turn hold the inner ring. If the center piece requires a lot of pressure before it moves then this might damage the internal of the bearing. That's why I was reluctant and thought it is not easy to do!
