THE MOMENT OF TRUE.

Not those big ones. there are 4 small  O-rings around 4 studs for oil.  They are the studs with a larger gap around them in your base gasket image

correo escocés=33832 id de usuario=109¿Por casualidad estás usando un tensor de cadena de levas ZX10

I'm thinking about getting one from a ZX10.
  
The one I have mounted now is Chinese and I'm not convinced.
 

This is the CCT roller from my '79 project.  A ZX10 CCT had been installed.  The bike did sit for many years but the concern for the heavy spring in the ZX10 tensioner is clearly shown in the Chain Pattern on the roller; similar to yours.  The asymmetry to the pattern on the roller would suggest that some slack somehow got the chain off-center, likely when it was parked for the last time.
Just pointing this out.  You can arrive at your own conclusion.
 
 
 

Christine came to me with her original chain tensioner. 



As I told you I have mounted a tensioner of Chinese origin. 

 

The base of the pusher is round unlike the original which is flat. 
 
 
It has not run for more than two hours and this is what the tensioner wheel looks like.

 

 

 

Respecto a las juntas tóricas de los espárragos del bloque del motor, tengo que cambiarlas; las que estaban montadas ya no se pueden reutilizar.



 

Mañana compraré un juego.

También tengo que recortar el orificio de drenaje de la bomba de agua en la junta de cartón; haré una muesca con un cúter.

is there a tool on this site that can convert this last last post into english at least on my computer its not in english I get the idea however it would be nice if for me anyway if it was in english
