Hoarder that I am I now have 3 old timing belts.

Old A/C, Alt, PS, Airpump belts if not carried in the spare wheel well as spares get used as ties for extension leads, garden hoses etc.

I can't think of anything to use the old TB's for - not much point in carrying a spare one LOL

Suggestions or do I just break the habit of a lifetime and ditch them.

You could sell them on ebay... NOT!

Throw them away - there is no point in keeping them, except as examples of the species.

There is the Castro Halloween Party tomorrow in SanFancisco, I am sure someone there could make it into a costume or something.

Keep one to use when you time your cams. You don't want to time cams with a new belt because when it wears in, the cams will not be in time anymore.

Thank you Thank you Thank you Louis

I knew that there was a good reason for keeping them.

Jon,
You only need one old belt. You'll have to tear yourself away from the others. I say this laughing because I have two or three old T belts hanging up too. Those are about to be joined by a special T belt that did it's job very well far longer than it should have. My neighbor brought his '89 5 spd over to change oil. It had a strange clicking sound at the front of the engine. I looked down there and saw a timing belt tooth laying by the oil level sender. He shut the engine down immediately. This is what I found after the covers were removed. The no tooth section is about 12" long and the cams are still in time. The engine stopped at 45 deg BTDC, #1 cyl. The car has about 85k miles and the belt was never changed. We also took out the in-tank fuel pump. The hose was split, but not apart. Lucky guy he is.

WOW talk about his timing!

I think you saved a near disaster!

Interesting that the car was still in time with a 12" gap in the belt. I guess though that the sprockets must grab more then 12" of the belt at all times anyway. (although actually it dosent look like it does.)

It was interesting that the small amount of tooth "residue" on the belt gave enough grip to keep the timing. The gap in teeth is longer than the cam sprocket contact area, and the crank sprocket only had the almost smooth belt for it to grip for nearly an entire crank revolution. The clicking sound I heard was the rollers that are under the crank sprocket forcing the timing belt tooth back into the sprocket. Apparently, there was some slippage, but less than a half tooth and the rollers did their job. I've always wondered just what those rollers were supposed to do, and now I see. The belt tension was good. I had checked it a couple months ago and suggested (for the 17th time) that he had better get the belt replaced.

holy she-ite .... I know that car too. GREAT save Louie.

HA HA HA

Thats so funny, what the hell was he waiting for. does your neighbor not know your a 928 guru!

I cant think of a better neighbor to have. Hopefully he dosent drive the thing and has already ordered up the parts he needs!

I left mine at my collage machine shop they work great for lifting engine bocks into the cyl hone and decking machine with the chain fall. The longest factory TB has many uses!

Good save Louis

Do you think he would be interested in 2nd hand TBs LOL both still have the writing on the outside, only 30k on one and 7k but 6 years on the other.

i just realised that saving one for cam timing is probably not valid - i'ld do it with the belt that was already on then replace the belt - buggah.

I used to have a very old but large lathe (wish I still had it) that originally had leather belt drive which I changed to reversed double TB drive - took 4 Tbs from my GM astra cut reversed then superglued back together, could probably get away with one 928TB.

Great save Louis .... interresting too when considering the flip side - there is a dry looking water pump that has also likely seen 85K of service.

blown 87

I do not see how that engine could have made one more turn.
Actually I do not see how it went that far, that is a lot more teeth than contact the crank gear.
That man needs to buy lotto tickets.

I hang them up like trophys - good discussion point when BSing and drinking beer.
