There was a tale of a 964 owner whose belt broke at considerable knots and he ended up with a bent crank, holed pistons are more common but not as common as nothing, they usually break at start up so don't run with a broken belt. Recommended change is 100k Didi supplies full kit and repair as stated, Type 911 supplies belt, pin and rubber seal kit. Yet another winter project as mine has clocked 170k. Did I once say I was getting bored? _________________ Porsche 944 S2 Coupe Guards Red

Recently gave a mate who has a 964 Anniversary a hand with this job, he bought the bearings from somewhere in Germany, probably the place quoted as they are one off sizes either internal or external bore I can't quite remember.
We replaced all bearings and seals, a bit of a faff but doable if you are okay on the tools, freezing the bearings and heating the housing helped to assemble. _________________ 997 Carrera 2S 54 Arctic Silver

Great thread and makes a change to usual valuations....
Ok so I got mine done and re-installed on Friday PM, upshot is that it's a fairly doable job. I managed to remove just the primary shaft and install a new belt over the secondary shaft. Removal of the secondary shaft requires you remove the cap at the bottom which without destroying it seemed difficult and I had no replacement.
My bearings seemed in good order so I simply greased them up which has made my life a little easier.
Unit during install, your can see the two halves separated
After install and cleanup
The pin is actually tougher than you would imagine and took some serious persuasion to knurl over on both ends to prevent it coming back out, in fact I set-up my 10T bench press to help me out.
The real key to all of this process is to ensure you align crank pulley and disis to the markings when you remove and when you put back, be extra careful during returning your disis back into the block, they engage with the driven shaft and move, this throws the set-up out of timing, you want the marking to line up exactly and you removed when the dissis are in situ, and not on the way out or in as they move due to the toothed gears.
You can see the rotor arms here aligned with markings on dissi case
My belt was in ok order but I did spot a slight fray, I'm glad I've done this job now.

.....ok, good Job !
The second runner should always be removed - that's what often looks like. The cap on the bottom can be removed with a small screwdriver and then brought back to shape. These two bearings often look chaotic !

If you mangle the cap covering the lower bearing in the secondary housing they can be found on ebay, stainless even. Search under core/frost plugs/caps. Not started this yet but got one just in case. 1 1/4" from coreplugsintl. _________________ Porsche 944 S2 Coupe Guards Red

I'm going to do a full engine rebuild in a few years so I'll swap the bearings then.

I replaced the belt on my 964 a few years back, it's not a difficult diy job and as others have posted there a a few links which give step by step instructions, the hardest bit was compressing the spring to get the circlip back on.
Just make sure the engines at TDC when removing the dizzy and that the rotors are correctly timed on refitting, they turn through around 30 degrees when pushing the dizzy back into the block due to the helical gear so it can take a couple of attempts to get the primary rotor to be positioned to cylinder 1 on refitting, it'll be obvious though if you're one tooth out on refitting.

Guys late to this but had this problem with my dizzy belt.
After i stripped the dizzy down it was apparent that I had a seized bearing which caused the belt to snap.
I ended up shipping my dizzy to Dennis at Elferwelt in Germany to be refurbished.

Interesting . Their site looks good but all in German
How much did your rebuild cost?
How long did it take?

Probably best to get a quote from Dennis but mine cost 318 euros. Which included replacement of the 4 bearings, belt and pin.
Found him via German ebay and I think he does work for Porsche museum although I could be talking crap...
Total turnaround time was 2 weeks.

Thanks manners
I might get a quote and then send it off. My car is running really well and my normal rule is to wait until something goes wrong before I try fixing it. But I'm thinking of driving it down to Italy in May for the Mille Miglia so it would be a shame if I've crossed the channel and then the belt breaks on the distributor.

All this looked far too technical for me so my Indy has swapped out the belt as a preventative measure
Some suggestion the belts are no longer available from Porsche  _________________ Alfa Romeo’s 4C is everything a Italian sports-car should be: it’s gorgeous to the point of pornography, distinctive enough that nobody will ever mistake it for a Porsche, handles like it’s on rails and steers like a kart.
