I have a 81 spider and the driveshaft coupling breaks
This is the original one new

Can someone tell if I can put something with more resistence and where I can find it, or put another of other model or car?
Do you mean it breaks frequently, or this is the first time? If it breaks regularly, you are either abusing the car, have installed much more horsepower than stock, or you have a bad carrier bearing support/U-joints. Or you have a transmission/engine leak and the oils are destroying the rubber.carlospena96 wrote:Hello

Rubber parts even when hermetically sealed break down even when not in use. They off-gas the compounds that keep them flexible or have them settle following the course of gravity and get stiff or simply fall apart. Even the Smithsonian Institute is facing this when conserving items made just 10 or 20 years ago as they sit unused on the shelf in controlled environments however they still deteriorate. My father was an engineer for almost 50 years in the rubber industry who designed long lasting rubber formulations for the military and those formulations would not be cost effective on a consumer car Guibo that typically sells for around $25. The closest thing may be the $69 heavy duty one that Ricambi sells however even that one while very good is not quite there. In the size for a 124 Spider a Century grade Guibo would probably cost well over $100.fiatfactory wrote:I think his point was more to do with Germany reuniting in 1989... and the time lapse to 2008 when the part was supplied to him...although I believe if boxed, handled correctly and not exposed to sunlight a timing belt should last that period of time without issue. Most modern cars have around 10 years between belt change (150 to 200k km service interval) and that's being heat cycled... something sitting on the shelf is under far less stress.djape1977 wrote:given the quality of parts made these days, made in west germany might not be so badbaltobernie wrote:Upon rebuilding my engine in 2008, I received (from a vendor no longer in business) a new timing belt marked prominently "Made in West Germany"
I still have some OE tailshaft couplings with late 1990's date stamps on them I still regularly sell and fit without any issues ...and I would rather use a 25 year old well stored Pirelli coupling than a new production coupling from eastern europe myself.
