Tensioner update question?

I have my 930 in for a valve adjustment and talking with Dan at the Werkshop in Melbourne, FL, he suggested I look into the update in the cam tensioner that came out in '84. Mine is a euro 82 930, and apparently has not had this update.

Searched Rennlist and here, did not find much (might be searching with the wrong words).

Any info/advice?

Thanks in advance.

Matt,

It's a chain tensioner, not cam tensioner. Try again with your search and you'll find more than you ever wanted to know about it.

My opinion is that it's a generally a good thing to convert to the externally-fed Carrera tensioners, but it's not the "no brainer" that some people will suggest. There's one big advantage to the original 930 tensioners -- they're entirely self contained. Those little external oil lines on the Carrera tensioner, though usually reliable, provide yet one more source for a leak that can be particularly bad near the turbo and hot exhaust systems of a 930. Over the years, I've had really good luck with the latest revision of the original 930 chain tensioners, (and I've seen failures of the Carrera tensioners as well) so I would say that it's not a necessity that you make the change. What I would want to do for sure, though, is make sure that your chain guide ramps are in good condition and are the newest generation. They, too, have changed over the years and the earlier ones (I think older than 82) were prone to failure and can cause a big mess. If a ramp fails, you could have a sudden and catastrophic loss. If the tensioner goes bad (the original style, in particular) they usually fade out more slowly and give you enough warning (a rattling sound at idle) so you can get them repaired before any damage occurs.

A week ago I would have said they'll be fine. Today I say replace them. I just did mine and I could squeeze the left plunger about 1/4 of the way down with my index finger. I could squeeze the right one about 1/2 the way down with very little effort. While they were still in I could push the idler pulley enough that the chain hung slack. I would at the very least inspect them but there is no doubt in my mind that it is money well spent.

Thanks for the replies. I meant "cam chain" but was in a rush which is like you said probably why nothing came up. Thanks for the great info... have some reading/thinking to do!

My comments relate only to conversion from the 930 tensioners to Carrera tensioners, not to whether the existing tensioners need replacement. Of course, if your current tensioners are bad, then you need to replace them with one type of tensioner or another. The question is: what type of tensioner do you install? Each has its advantages.

convert em and reramp while you have it opened up. snug the oil lines down good because they will leak if not. get the colors down when you order the ramps also.
