It probably makes sense now. If not from a mileage standpoint than certainly from age.
I've considered rebuilding mine for the last few years.... At this point, my 993 rat rod has 60,000 miles and I think a rebuild over the Winter would be prudent.

Jim,
As a minimum, you'll need a distributor drive belt available from Pelican Parts for example, and the distributor drive pin, part number: 930 602 922 00. I'd get a couple of the pins in case you mess the first one up.
Take your time setting up the distributor in the drill press so that the pin gets drilled out straight. The pin is quite soft.
There is a nifty trick to pressing the drive gear down to slide the pin in.

Not having any problems but it looks like I am dropping the engine for a few other items, its easy to do this while I am in there and then I dont have to worry about it.

Man, the 993 is how old now? At 15 plus years the "might as well do" list while the engine is out is getting longer, and costlier. Its DNA is engine....
When my distributor belt breaks - that's when I'll look after it / or should the engine come out tomorrow. My .02

I just shipped mine to Steve Weiner a month ago and my car had 85k on the clock.
The belt was starting to show some wear, at 100k I would definitely get it rebuilt.
You got your money's worth and then some on that part.

As of this morning, it has no functional issues. With the engine out it is a easy job. If it has an issue a few months from now while its in Florida and I have to pay someone to repair it, I will be upset. I figured its easy to do now, so why not. I realize it may not need anything but a refresh isnt a bad idea since the engine will be out anyway.
I spent some time talking w Alex last night on the phone, I will pull the distributor and check it. At minimum I will replace the belt and pin. If there is play in the shaft, I will send it out to have the bearing replaced since the are apparently nla and a non standard size.

I opted for a Bosch remanufactured distributor to eliminate any bearing issues (they seem to be the only ones who have the unique bearing). The price was a couple hundred over what the other rebuilders charge but I've have a little bit extra piece of mind.

I was referring to the belt not the distributor itself. Not sure if true, but I thought I was reminded that this is recommended to change the belt at 60K. I know I choose to defer it to about 90K but mine would not have lasted 120K.
I guess your mileage may vary and if one is willing to take the risk why not. Mine is a DD and preventative maintenance in my case has its merits.

If they are claiming to have replaced those angular contact bearings...I'd ask for the old bearings back in a zip lock bag.
