Why own a car that has less than outrageous horsepower, lots of maintenance? Well, in my experience you can go into a corner at "Oh my God, i think i'm gunna die" speeds and the car zips around them like it's a non-event. That why i have one. Who cares if it's not super fast in the straights?

I just use the automatic spring-type tensioner (no fancy P9201) on my 87 and don't worry about it. I'll probably do the belt a little before 30K since it's only $10 or so.
There was an interesting thread awhile back about the feasability of making a plastic insert to go between the timing & balance belts so if the b/s breaks, it won't get caught up in the timing belt. Then you'd just do the b/s belt less often since it costs more.

Does anyone know the pitch code, pitch, and number of teeth for the timing belts on these cars? Also, for whoever posted first about the kevlar reinforced belt, do you have the # for the mechanic who suggested this? I am very interested in figuring out if this might be a viable idea...so far the kevlar belt manufacturers I've looked into have not had 2 sided belts...

OT for 928's
Paul Jager, a 928 owner swears by this method for retentioning timing belts in 928's.

He's even made up a 928 Maintenance note book. Anyone up for making one for our 944's?

I'm getting confused.
The S2 has an automatic tensioner which needs re-tensioning - after 1500 -2000 miles??? yes or no.
Why is it you need to pay mega bucks to a garage to have the tension checked. We don't do this with generator belts we check the tension by pressing down on them with our thumb.
There are some 944 owners out there who don’t have the appropriate and expensive Porsche tool and do their belts this way (with the thumb) let’s hear from them - how satisfactory is the job - do they drive with piece of mind about their workmanship?
Why can't we do this job ourselves without expensive tools (must admit I've not had to do it yet - my son, the po, had it done prior to my purchase)
I don't think there was a re-tensioning carried out on mine after the last change.
What do I look for when I take off the covers to check out the belts????

Bruce,
The belt needs to be retensioned...thats the bottom line. As for the rest, I'll let someone else handle it.
Has anybody thought about possibly making wider pulleys to accomodate a wider belt? If necesary, pushing the balance belts out a little further. Same goes for the belt covers...

zehnd: hmm,that's interesting, it's like the twist method but without all the 'well, how hard do I twist it?' problems. I know some other 928 guy produced a $20 tensioning gauge, but it was specific to the 928, and I forget how it worked. Let me dig it up.

I use a spring balance to weigh the enormous trout I catch (dreaming again) surely it's not impossible to work something similar to pull against the belt to check the poundage.

what was the verdict on the substitute tools? is the krikit and that other one (i forget the name) just as good as the official porsche tool? how much better are the tools than the automatic tensioner?

I have used the krikit and have not had a problem for the few months that I have driven the car. At first the issue of the 9201 tensioning the belts made me hesitant about buying the car but after my neighbor who works on Ferrari's, Porsche's, and Jaguar's said that he tensions all of the belts by hand, I began to question what is so special about Porsche belts that require a $500 tool to tension them. With the krikit getting consistent results, I think it is safe to assume that if you tension the belts with an equivalent value, then the 9201 is not needed.

For those complaining about maintanance:
"Cheap, fast, reliable--pick two"
I actually need to go out in the garage and retension my belts this week using the Krikit tool. My odometer's broke, so I've been going by estimated miles per gallon * gallons bought
