There's a rounded edge and a sharp faced edge to it that is hardly noticed unless you look closely... Don't ask how I found that out.... But if it's wrong your sled will bog on bottom and be hurky jerky on engagement. It's something worth looking at for sure. Our group didn't know until we put one together the wrong way... Sled still ran but was off a little and the symptoms you describe and I mentioned above sound similar to what ours did... Now it's perfect.
I told you silber would blow your minds with the new internal waste turbo... Even cheaper than the externals out now! Just keeps getting better !
I don't know how a rounded clip or flat faced one could make a difference. The hub doesn't move...The clip is just there to stop the cup from flying off. Am I missing something?
This is from the factory service manual and it doesn't mention it either. Is it possible its just coincidence that you noticed a difference?
Disassembly and Assembly Process
1. Remove the screws from the helix, then carefully pry the helix out of the moveable sheave, or gently tap shaft on a block of wood.
2. Install the clutch in the clutch compressor fixture, PN 8700220. Install the extensions, PN PS-45909.
3. Wearing eye protection, carefully compress the roller assembly to gain access to the snap ring. Remove the snap ring.
4. Slowly release the fixture arm to remove the roller assembly and spring. Disassemble the clutch sheaves.
5. Inspect the sheaves for abnormal wear. Clean sheave faces with a Scotch Brite pad and a solution of warm, soapy water.
6. Inspect spring, spring cup, spacer and rollers for wear and replace as required.
7. To assemble the clutch, slide the components back on to the stationary sheave shaft.
8. Align the notch in the roller assembly with row of
6.24
double splines on the shaft. Slowly compress the spring and roller assembly down on to the shaft. Install the snap ring making sure it is fully seated in the groove.
9. Install the helix by aligning the rollers with the ramps. Push the helix down into the sheave while keeping the screws holes aligned.
10. Install and torque helix fasteners to specification.
