Phase 3 - Separating the Stack of Plateshttp://imgur.com/a/tX5O7The images uploaded out of sequence, so please bear with me.
The main purpose of separating the stack of friction plates ( apart from covering one self with sticky bad smelling silicone fluid) was to determine whether there was a particular stacking sequence for assembling the plates.
You can see from the 4th picture in sequence, that the inner splined plate has a notch in the outer edge at the 12 O'clock and 6 O'clock positions (the picture is rotated 90degrees)
Also, the outer splined plate has teeth missing also in the 12 O'clock and 6 O'clock positions.
The 3rd picture in sequence shows the raw stack.
If the outer splined plates were assembled in alignment, there would appear a missing tooth gap equispaced on the outer edge of the stack.
The missing tooth position was not aligned and a missing tooth "hole" was randomly spaced throughout the stack.
Conclusion: The outer splined plates are position (assembled) randomly in the stack.
The 5th picture in sequence shows the hub for the inner splined plates.
As the stack was disassembled, the inner plates were stacked back on the spline in the exact orientation that they were disassembled.
As each successive plate was placed back onto the hub, it was clear also that there was no pattern to the assembly orientation of the inner splined plates.
So, the present conclusion is that the plates are assembled in a random fashion.
The 1st, 5th & 6th picture show the spacer ring that RX25E alerted us to in his post.
These rings go between each outer splined plate, surrounding each inner splined plate, to help keep equally spaced gap separation between each plate.
Yes, these are the same as for the 5MT C-D unit, however I did not mention them earlier as they may have created information overload.
The 1st, 3rd & 4th picture shows a gear toothed type machining around the outer edge of the end cap.
This feature was no on the 5MT C-D unit end cap that I disassembled?
My guess is that the feature is there to help agitate the silicone fluid and help pump it around the inside of the viscous coupling. At least, that is my guess?
The next step is finish disassembling everything and cleaning all the black gunk from the internal components and the plates.
