I came across this how-to-use your KriKit V-Belt Tension Gauge video on the Dayco belt site. There are plenty of other informative "belt" videos on YouTube...just search on "Dayco belt". These videos can be copied for future reference.

BTW, anyone looking to get one, they're about $20 and you want the KriKit I model (lower tension).

Thanks for sharing. This is bookmarked ...

Any decent 968 guy could show you how to use it. Mine is marked with various belt tensions, as well as it being written on the box.

So what would be the tensions using this gauge for the belts on a 993? That would be fan, alternator and A/C?

If there is an RS pulley, would there be a different specification?

Cheers,

A little tool may not be bad but,............................
Because of variants in V-angle, size, material and design, I rely on feel and lean towards keeping the tension on the lighter side to prevent overloading the bearings.
To insure grip and prevent slippage, I use a little belt-dressing sprayed on a rag and rubbed on the belt while turning the engine by hand.
Commercial belt-dressing is harmless to the material and aids in flexibility.
My personal experience is seeing it used in Industrial applications on a regular basis with good results.

Sorry about that Mike...missed your post.

From the Porsche Repair Manual

Drive Belt Tension
Old belt: 15 – 23 (cold); 20 – 28 (hot).
New belt: 23 – 35 (cold); 28 – 40 (hot).

This is KG, not LBS, correct?

I'd go by the Porsche Technical Bulletin that states...

For a "used" belt that has already been stretched from prior use:
Cold Engine: 15 kg to 23 kg tester scale units.
Warm Engine: 20 kg to 28 kg tester scale units.

The TB discusses the belt tension procedures for new and used belts as well as for the A/C belt.

I worked with the Krikit "scale" and tried to come close to the Porsche spec. When done it passed the "thumb test".

I used a Krikit gauge once on the 993 belts and found it utterly frustrating. They are automotive V-belts, not mission-critical items aboard the Space Station...

Andreas, you get "the feel" after a couple of times. I got three identical readings in a row after I got the hang of it.

That they are not, but there is a reason for bearings going. And when you read about a RLer not being able to install something as simple as a cabin air filter cover, some need all the help they can get; others use a torque wrench even if they are the last ones that need to.
