Carrera Tensioners
I installed this upgrade on my 77S during a complete engine rebuild. To my surprise when I started the engine it sounded like it had collapsed tensioners. (believe me I know what that sounds like). I followed the installation instructions that Wayne wrote some time ago. Now I found a addition to a tech paper I think from Pelican that you must "bleed" the tensioner
before installing like we use to do with the old style tensioners. I made several phone calls to tech support including one today and no one mentioned this important installation requirement. SO BE WARNED, BLEED THEM BEFORE INSTALLING. I now have to pull them off and bleed them. A fairly big job. |

try disconecting the extra oil lines to the tensioners and "power bleed" them with a pump style oil can and spare bango fitting, you know the stlye oil cans that us old guys use.

I saw the tech article on this website while researching before I ordered mine. I'm happy I did or I would have had the same problem. Submerged mine in an oil bath and pumped out all the air before installing. Messy but effective.

Thanks for the input. I pressurized the engine with oil up to 30 PSI before ever cranking it. If there is air in the tensioner piston, there is no way to get it out since it is a closed system and the oil input is at the high point of the cylinder casting. I guess the only way these work without bleeding is if they still have oil in them from the factory. Mine sat around a few years before I installed them.
