Hi Folks,



1st post here as ill be picking up my baby in two weeks ( black '93 with 100K. Beautiful interior too!)



Ill be looking to do the belts/ roller and waterpump asap.



Ive done my best to research the interwebs, but im coming up short on some 968 specific questions So here goes: Ive come to the conclusions that a step by step 968 specific timing belt instructional is really only available in the shop manual?



Some questions:



1.Am i better off using the factory manual on CD or improvising from the Clarks garage website?



2.Am i correct in the assumption that a tensioning tool should still be used to set initial tension prior to the hydraulic tensioner pressurizing at start-up?



3.It seems the tool i wanted cant be used (ArnnWorx) for the 968 (per website), so im left with the factory tool or the Kricket?



4.What is the most effective way to determine if the hydraulic tensioner is in good enough health to re-use, or needs to be tossed?



5.Besides the flywheel lock, tensioner and 2 thin wrenches for pulley adjsutment, what other "proprietary tools" am i leaving out





Thanks for sharing your knowledge!

ArnWorx tool works fine for the balance shaft belt. I've used it multiple times. I did not have any issue with the timing belt and hydraulic tensioner. Flash (on this site) was assembling a DIY but not sure if it's ready for prime time yet. If you need the flywheel lock and wrenches, let me know.

1) You should combine the info you find here and elsewhere, and take it step by step. A bunch of reading will save you a lot of time in the end, and perhaps some serious technical 'issues'.



2) The hydraulic tensioner is used to tension the timing belt only. It needs to be compressed SLOWLY when taken off the car. When the new belt is installed and the tensioner is doing its job, no other tools are necessary.



3) You can use the Arnnworx tool to check the balance belt's tension, but it can be done without. I do it without, there are ways to check the tension by hand, it is not THAT critical. Read up on it would be my advice.



4) No idea, mine looked ok so I reused it, although 23 years old. No problem.



5) Maybe it's a good time to check the front engine seals for leaks. Should I emphasize to read up on it? ;-)





If in doubt, ask. Many people here who know these cars inside out (I'm not one of them, but I did al this stuff very recently, and so far with success - where did I put that block of wood?).



Good luck!

Last October 15/2013, I bought a kit from Pelican Parts $386.75 that contained the Timing belt, Balaced Shaft Belt, 2 tensions rollers and 3 idle rollers. MY mechanich who does a lot of work on 944's & 968"'s as well as the older 911's said he was very impressed with the kit as is was complete I can not find the receipt at the moment to give you the part number, but I am sure if you call them up with the date of purchase and the desription of what was in the kit they would be able to give you the part number.



Went to the pelican site the part number is TB-152-293-k1-m21 $360.00 ( maybe the $686.75 was shipping)

no chance in hell i would put that kit on ANY 968. contitech belts are not the choice. they are known to stretch like rubber bands. most mechanics i know refuse to use them. over the 11 year period that i have been paying attention to the 968, every single belt failure reported on any of the websites has been contitech.



most of us now use gates exclusively. some use dayco. both of those companies were involved in the original design of the system. gates and dayco were the original belts specced. there was a brief period where conti was the porsche supplied belt, but porsche also ditched it. gates and dayco are again the OEM belts.

All the Porsche dealers here use Continental belts still. For some reason.
