Yeah, the lifter idea really doesn't make sense when you think about it. It was probably my misunderstanding of the context from a private conversation I was having with someone on the subject. Putting my newly-rebuilt engine on a dyno is probably a good idea, and it would be interesting to see if I left a few hp on the table as a result of the cam timing not being optimal for the mods I did. I ended up pretty close to the middle of the adjustment, and repeated the procedure twice and got the same result both times, and the engine seems to run strong, so I'm probably not miles off, but a dyno run sounds fun and interesting.

Hi all



Well got gates belts, but local porsche dealer not interested in ordering tool, couldn't believe it, dealt with them through the trade for over 10 years.



Few specialists in uk to try, if not i am in Florida in June, I will try and get one then.



Thanks

You mean they weren't interested in ordering P-9201 to tension the belts?!



You can find them on eBay from time to time, or ArnnWorx has an alternative that I've used with success.

Holy cow. Tell them you'll order it yourself, if you have no other service option. But it will remain your property. I wonder what position PCNA would take on such a thing?

the only reason i can think for them not wanting to order it is that it would be at least one less service job they would get.

Well tool sorted I think.



It should arrive soon, just repairing hatch trims, keep breaking free and then I will start cambelt.



Wish me luck

Hi all



Well i have started work on car, slow as working outside and weather been poor, got flywheel tool, still got to install it, but can some one advise me.

The balance belt seems awfully loose and looks like you have two adjusters, one at the bottom and one in the middle, the middle one is not touching the belt, this cant be right can it?



Also how do the remove the coil pack which seems attached to the top engine pulley?



Took screws out, seems still tight.



Thanks

Thanks,big help.



Looks like balance belt is a bit loose as the clearance is a lot more than a credit card for the idler tensioner.



Cheers

there should not be clearance there. the drawing in the manual is deceiving. if you look closely though, you will see that it should deflect that belt up to 1mm.

I think he's talking about the clearance between the idler and the balance shaft gear, Flash, as the video shows a credit card being used to set that. On the top, the idler should deflect the belt upward a maxiumum of 1mm.

Hi All



Well the weather eventually allowed me to attempt to change the belts, which are now on.



However can anyone in 968 world help with a couple of questions?



Firstly are you safe using the old circlip that holds the tensioner bracket in place?



Secondly all time marks line up apart from the top balance shaft shaft mark, its out by half a tooth ref the belt too much clockwise, so no matter which way i turn it will still be out by a tooth.



Any advice? Or it may be how it is !!!!!!!!!!!!!!!!!!!!!!.



Thanks

To evaluate I would need 3 straight on pictures. One of the top balance shaft sprocket, one of the bottom balance shaft sprocket and one of the timing belt drive sprocket.

I think it is only by luck that all the timing marks will line up perfectly (crank at flywheel, cam at cam cover, and both bal. belts with there respective markers on the front covers. If I line up either the crank of the cam, the others are always a little off the mark. But, half a tooth seems further off than I'd expect. But, on your car, with the length of the individual belts, it may be as good as it gets. Pictures as mentioned above would be a great aid to seeing if anything is amiss, or just the way it is going to be.

Be certain you turned the lower tensioning idler in the right direction, as I recall that can make one of the marks be off by a half tooth?

Thanks for the advice, i believe you turn it clockwise to tension the belt?



Am i correct on that one.



I will recheck it when the weather improves, the funny thing is that i marked all the pulleys with correction fluid before taking it apart, and the pulley that is off by half a tooth seems to be in the same position as it was with the old belt on, the previous belts were replaced by a porsche dealer.



And it ran fine, however its a miss that the marks are out .



Thanks for the advice.

According to the shop that initially did mine, they are often off by a bit. But that same shop left the upper shaft off by a full 180 degrees.

I hope this is the right place for this. My import mech that is doing all the owrk on the car says Porsche reccomends changing the timing belt every 10K.. Anyone have any thoughts on this?



The question arose when I asked him about changing the cam and crank seals as long as he was in there and he said that if they were supple to leave them as we would be back in there soon enough and when I asked why, he brought uo the 10K item.



Thanks

I think it is 30K or three years,whichever comes first. But I will wait to hear others pitch in!
