Maybe I didn't read closely enough, but was there ever a determination made about the cause of the belt wear on the smooth side? Or was it judged to be in the realm of normal? Sorry, I had to ask. I'm such a noob.

Glenn,
The belt wear still has a ? in my eyes but maybe it is normal.
It does come in contact with the idler roller and thats about all.

Hope this post was useful, wouldn't want to be a noob with no clue.

User, uh, Doc
I know this isn't much of a contribution...but if you try to scrimp on a snap-ring plier set, you'll probably regret it when working on some 928 snap rings. I went through a couple of cheapie pliers before I realized that it takes a small AND VERY STRONG TIP for some snap rings. Bending and breaking tips was too common an occurance and can be very frustrating. This is where the Harbor Freight tool failed on me.

Roger,
The two external snap rings are 24x1mm and 18x2mm for the idler roller and tensioner rollers respectively ....

Garth,
The 18x2 could be difficult - I am still looking.

Looking at the DIN standards for Metric Circlips (Snap Rings).

Shaft diameter is 25.2mm - Groove I/D is 24.5mm - Groove width is 1.5mm

DIN 471 External Metric shows the closest match

Shaft Diameter 25mm - Groove I/D is 23.9mm - Groove width is 1.3mm
Snap ring I/D 23.2mm x 1.2mm thick.
Part number = D1400-25

I need to track down one of these puppy's.

What suprises me is that if Porsche were to use a non standard snap ring then they would call out a Pt Number for it on PET - but no number exists.

Roger, are you looking for the snap ring which helps locate the large roller on the shaft? Just ordered one from 928specialists, I have the part number at home.

Apologies if this is not what you are looking for, this thread is long !

Went back and looked at PET as I could not believe Porsche would not have a number for the circlip.
If you are interested look at PET MY 88 illustration 103-10 and find item 47 on the list of parts.
Item 47 is not shown on the diagram. However it is a circlip with a Pt No N0122771 which is an update from Pt No 900 908 006 00
I just ordered one and we will see if it the right part.

No it is the other one and I may have found the Part Number - see my last post.

Well I checked with the guru's - DR & Jim B - and drew a blank.
I guess I am on my own here!

NAPA, try PN 1342, 1340 or 1047, 1045. 0.924" I know it's not metric, but looks to be close. Take your shaft with you.
