I am wondering if this replacement timing belt is the wrong one. Would you say this is a square tooth or a round tooth belt?

It has characteristics of both doesn't it; it looks like they tried to make a "one size fits all." Other items I'll get from the local supplier, but not the T-belt. Going to the big 3 will prevent this identity problem. The real question is how will it perform? <img border="0" alt="[nono]" title="" src="graemlins/nono.gif" />

 

May be a dumb answer, but maybe it was for both.
Is is a Porsche brand name belt or aftermarket?

It may be an aftermarket attempt to fit both.

 

The bag it came in had two labels that matched for the desired belt. It's an aftermarket belt from Zims and is not universal - has a specific Porsche part number. A friend thinks it was a mistake, gave the belt to me, then bought a Gates/Porsche labeled belt from the dealer. Before I say which it is supposed to be, I wanted to get some opinions on which one you think it is.

 

Its doesn't quite look like it will fit the shallower square-tooth gears, so by eliminations, round? Don't like it for either!

 

Have you tried to match it against the sprocket?.

I would say square toothed.

 

In any case, it probably will fit best in a 16V engine ;-)

 

I have heard that using a belt that doesnt fit properly in the teeth of the sprocket will wear the squareness off the sprocket teeth, thus making it possible to slip a tooth sometime in the future...

 

Here's the scoop on the belt from Zims, passed on to me by Bob in the DFW928 group - Zims says, "It is a legitimate late model belt produced
only by the Flennor company, A German Co. that Zim's has used for years. The reason for the flat bottom with the groove in it is an improvement said to give dirt a place to go, lessen wear, & quieter running with less
whistle. It is strictly a late model belt, not only are the teeth deeper, but they also
have a different number of teeth."

I have heard of people mixing them up, though. If the tooth pitch is the same, then it would make for a different *length* belt.
