Bench Bleeding Carrera Tensioners
I'm preparing to do the recommended upgrade to my 76 911s with a 78 3.0L engine. I've got Wayne's book, read all the articles on the forum related to the subject and as a final re-read before diving in, I noticed an addendum to the on-line tech article. The addendum states the tensioners need to be bled by submersing in oil, pulling the keeper pin and pumping the actuator until all the air is expelled. This sounds reasonable, however having not done this I am concerned replacing the pin in order to install the tensioner may be a problem. Does anyone have experience in this Porsche recommended bench bleeding procedure that may be of assistance?

What I did was:
using a small 2qt bucket fill said bucket with 1qt oil completely submerge tensioner in oil Then- pull tensioner pin pump tensioner by hand a few times until all air bubbles stopped coming from tensioner and finally, compressed tensioner one final time with one hand while inserting pin with the other hand presto... ready to go! repeat with the other tensioner and your set! Hope this helps I'm sure others will chime in with much more eloquent directions and descriptions, but thats how I did mine~ Good Luck

Great, that answers the question regarding the reinsertion of the pin. I may try to hook up the feed tubes and draw from a reservoir of oil rather than submerging, but either way I was concerned about the pin. That issue is solved...thanks for the quick reply.

The one quart oil cans were the ideal size for this procedure. However, I think they're collector items now.

i use a pump style oil can with a short hose attached to a banjo from an old tensioner metal line. use the normal banjo bolt and pump until it firms up. as far as squeezing by hand to reinstall the pin, that would be difficult....use a vise and go slow.

I did something similar and used a large channel-locks to compress during the bleeding and to reinstall the pin. Jerry M '78 SC |
