Hi all
It has been a long time since I posted on here. Lots of life changes and the 928 pretty much sat with very little use.
I am in the middle of a timing belt replacement. Last one was about six years and 1000 miles ago (shameful I know) with a pk tensioner.
Is it advisable to replace the hydraulic audi tensioner or just retract and pin it?
thanks
John

I replaced mine after 7 years and 50,000 miles. Mostly because Roger said it's so cheap why wouldn't you?

Why touch anything with those sort of run hour numbers unless something is obviously wrong?
Just try to spin the motor on a reasonable schedule- say a few minutes every month or two to help keep the belt pliable. Also important to keep seals and bearing surfaces oiled and especially the ac compressor seal face

My daily driver is a VW that uses that hydraulic tensioner. My recollection is that the service manual calls for it to be replaced when you do the timing belt. Now my recollection may be shaped by the fact that I always bought a new one because my timing belt changes were at 70k intervals. Not expensive, particularly on the Porsche scale, so I would just get another.

Thanks for the quick replies. I found a gates tensioner for a good price so I will likely order it.
After looking at the belt I would be inclined to just leave it but since it has been over six years and I have another belt, and the covers are off I might as well change it.
thanks again

Recommend contacting Roger or Ken (info@liftbars.com) to see what they say about your current bracket. Ken's made some modifications/improvements over the years and they might recommend yours for an upgrade. You can see his core and upgrade cost here: http://liftbars.com/prices.htm#pktsup.

With that low of mileage none of the Audi parts should need replacement.
Updates to the brackets were to fit a larger range of engines. Hardware improvement include through-bolt and nuts instead of the Audi supplied bolts. (You can get a updated hardware pack from Roger. Older brackets can be drilled to update them.)

^ Agree, just measure the extension before you take anything apart. There have been cases of the pistons being overextended.

Just 1000 miles...
My only question would be how stored? Climate controlled? Or subject to extreme temp variations (20 below winters and/or 100 degree summers).
If not subjected to extreme climate, a good belt should still be good.
Not good enough for another 50k miles over 20 years, but....

Stored in a garage but not heated so yes there were wide temperature variations. I will replace the belt since I already have one.
thanks everyone for the comments

It just has a range that it can operate in. See link.

Your belt will be fine. Really as long as your belt is tracking well, there are no odd noises, rollers are good, water pump bearing is good and if the tensioner is operating and not overextended just drive it!
Belts don't just snap, they get snapped or damaged by something else busted in the system.
But like Billu said above, there is always a but.......
