Replacing clutch helper spring. Missing part in PET?
 
Hi fellow Pelicans,

I’m in the process of changing a broken clutch helper spring and am having a hard time finding a rubber seal on PET. If you look at my picture, you can clearly see a seal on the charge arm but in PET it’s nowhere to be found. Worse case scenario I can reuse the old one but I’d like to replace it if possible. Any thoughts?

3 sealing rings listed as required for an SC, only 2 shown in drawing a possible clue?

Two goes into Bell housing at fork & shaft and one as pictured, there is no dust guard between Omega and Clutch Arm.

there are always 3 seals and the seal must be on the little finger to prevent dirt going into the vertical shaft and keep the lube inside ....
If you look on your PET it is written it takes "3"

Ok, so I guess they only appear to be of different size due to them being worn? The one between the clutch release lever and et bellarm seems way larger than the one sitting on the change lever. Where does the third one go?

i put one of item (4) above the helper arm , and one below the helper arm , and called it a day.

one goes on bottom of the fork and the next on top of the clutch arm and the 3rd on top of the finger..

Same. I used 915-301-139-00. Interestingly enough there was no old seal above the helper arm when I did this.

I didn't think there was either on mine, but when I got in there I found some hard remnants, long ago vulcanized through heat and the elements.
