I removed my timing belt tensioner to clean and refill it and on disassembly discovered a) 3 broken disks and b) that it was not correctly assembled last time around.
Here is how the disks were assembled:
The 5 on the right were "cupped" up towards the opening of the tensioner housing, all the rest were "cupped" downwards. My understanding is that they should be 5up/5down/5up...
Is it reasonable to think that the disks broke because the stack was installed improperly?
This photo is from Dwayne's TB and WP write-up... for the later version which has 35 rather than 40 disks.
So mine should look like that with another group of 5 on the bottom end. Right?
If anyone has 3 or more disks available for a reasonable price I am in the market... (I have to do a closer inspection to be sure there are none that are cracked).

Broken discs are not common.
Common on this Forum are people that have converted their cars the Porken tensioner...so finding a used tensioner that you can steal the discs out of should be a snap.
The "later" discs are not steel colored, but are a brass color....not sure if that was a change that was made for durability or for better heat reaction.
You will find that the boot for your early tensioner is NLA. I make a piece that will adapt a later boot onto your early tensioner. Both Roger at 928 R Us and Jim at 928 Classics carry these pieces in inventory.
