Timing Belt Tensioner 944.105.172.03 is currently unavailable from Porsche.
My friends have a 968 Cab that has been sitting at the dealer for a month, because the dealer tech says this part must be replaced.
The reason they took the car in was a coolant leak and a noise from the front of the engine (I did not have a chance to see or hear the car).
What do you guys do these days when new tensioners aren't available? Is there anybody who rebuilds the old ones?
Thanks!

You might try calling DC Auto, or some other used parts places. If not, it may be time to get creative. These tensioners aren't very complicated. A good machine shop should be able to correct what ever is wrong with the one you have.

I had to refresh my memory about it; the 968 uses a hydraulic tensioner that is unlike anything that came before it on 944s. Now that said, what about using a tensioner from an S2? I think the basic architecture of the engines is the same but I don't know enough of the important details to opine on whether the mounting holes are available on the 968 motor. The upside is that there are S2 tensioners readily available, even if they're somewhat pricey.
Any chance you can get PorKen to whip something up for you?![Wink](https://rennlist.com/forums/images/smilies/wink.gif)

Try reaching out to Karl Poeltl at Racers Edge ... he and his bunch of SP3 misfits probably have a good stash of spare parts as they
all race 968's
One of them might have what you need , surely between the three of them they've blown up a few engines and have leftover parts.

I've cleaned and reused them without ill effects on many cars including the 968. You just have to recompress them slowly and avoid pushing crud past the seal..

Is this tensioner built like the 928 tensioner, with bi-metal plates in an oil filled cylinder? Are the seals available somewhere (Porsche doesn't offer them)

it is a hydraulic tensioner with a spring and oil pressure inside. they are not rebuildable as stock.
they dont really seem to go bad all that often but they are hard to find.
i was going to use this setup on a converted 944 engine and spent a lot of time looking for alternative tensioners; i recall some Audi and Toyota units looked like they might be adaptable with some fab parts.

I was told today that the .03 part has been superceded to an 04 part, after calling the dealership after seeing a post on FB about them being re-introduced. Apparently they're in testing phase now.
Add that part number to the PN/s I entered weekly for two years into the Classic Parts Feedback form, along with the early dash.... and there are now early dashed again.

I have a used tensioner if you still need or a complete setup for someone who wants to convert to a hydraulic setup.

Porsche usually can give you a date by which they expect to have a part back in stock, if they indeed plan to make it available. Exception is that if the part has been kicked to the Classic program, there's no commitment to ever making it. For regular parts, they have been pretty good over the past couple of years at sticking to the dates.
A good, used part from a reputable dismantler might get your friend back on the road sooner, with minimal risk.
