Help me understand what I am seeing with my timing belt...

Hello SeanR: The play I felt is definitely radial. I did not feel any axial play.
Yeah. This is getting expensive. And it hurts...

Oh yeah! That's what is keeping me going. I positively adore my Porsche 928!
Those two months I was able to drive her were unlike anything I had ever experienced. This car was wicked to drive. And that is with all the faults.
Wait until I get all the bugs worked out...

Umm...yeah. I can just afford the one I have. Another 928 is out of the question. For now...
I do have plans for 'The Iron Maiden' rattling around in my twisted mind.

Got some more work done tonight.
I removed the engine harness so it would not be draped down over the water pump. And...my 'serviceable' harness is not. I have ordered a new one from Sean Ratts. I have decided that I am in this to make it right. It will just take that much longer to pay off the debts.
The water pump came off with little drama other than the sticking gasket. I will carefully scrape that off with a box of single edge razor blades. I am glad the shop cleaned all the bolt holes and fitted new hardware. Bolts came out with no problem. The water pump area on the block was nice and clean. I saw no evidence of any machining of the impeller pocket by any previous water pumps.
With the water pump out, I could feel play in the impeller side, as well. This water pump is done.
Plastic impeller = good.<br/>Play in shaft = bad.
All looks good and clean.
No machining of the impeller pocket.
I have some photos of the timing belt. As far as I can tell, it is still good and useable.
Back edge of the belt, shows no wear.
Part of the front edge of the belt. It looks burnished if nothing else. No fraying or shredding.
Another part of the front edge of the belt. Same burnishing, but you can see the cords.
I have photos of the tensioner pieces.
All the pieces look OK.
I am replacing the tensioning bolt and rear piston O-ring just because.
Copper bridge is a little bent, but should work.
Boot is still soft and pliable. Clamp is getting replaced.
No major wear or crud in the bore of the tensioner.
I've got to dig into the WSM for the significance of the different coatings and for the proper orientation of the washers in the stacks.
Finally, I have pictures of the crank sprocket and thrust washers.
All parts look serviceable. Both thrust washers show some shallow nicks and such. I am going to replace both of them just because.
I belive the paint dot signifies the front face of the sprocket.
Nicks on the edges of the teeth. Possibly from a puller. I am going to dress the nicks with a small fine file.
Backside of the sprocket shows some marks, possibly from removal.
Hope to get more work done tomorrow. May not be able to due to a press casualty tonight at work. I'll know in the morning if I get to keep my weekend and work on the Red Witch.
Thanks!

I would replace the belt. Believe me, I know that every dollar counts and these parts can add up quick. With the damage and the way it was positioned, it's probably stretched more on one side than the other. Plus with every millimeter of the width that the belt looses, the tension requirements change.

Hello Guy!
That makes sense. And...since I just blew 7 large on a new engine harness, I don't think $36 for a new Gates timing belt is really going to matter...
Though it does **** me off a bit that I paid $90 for this one, and now should get another.
Thanks!

if nothing else get this tool Knipex 8630300
12 inch straight jaw pliers that operate on a parallelogram ,
these are like having a metal press in your fingertips .
And many other uses,
the best tool in the box promise
They can straighten the brass doohickey .
While your at it get a new Isolator bushing thats pressed onto the tensioner pin.

Mrmerlin: Thanks for the link, Stan! I am a big fan of Knipex pliers. I have a set of Cobra water pump pliers both at work and at home. Damned good stuff.
As well, I will get a new isolator bushing for the pin.
outbackgeorgia: That is a good idea, thanks! I just looked it up, less than $3.00. 928 607 110 00.
Imo000: Not at this time. I am drawing the line at removing the valve covers. That, and I am too far over budget.
worf928: Don't know. He does that alot to my posts.
Well, this thread is at a bit of a standstill now. I am now just waiting on parts. I am continuing the intake refresh as well as replacing all coolant lines and overhauling the AC system.
Lots of cleaning to do as well.
