108-1 Gear Strut Rebuild (No Rings / Extra O-Ring)

Hi Scott, welcome to the Stinson world. Not everyone has the rings. Each strut assembly will have 2 different size O rings. I installed "quad" rings when I overhauled mine. Can't remember the stock # but someone will. Here's a link you might find helpful. Cheers

Thanks for the ring information and I appreciate the link.

I understand that there is an ID and OD O-ring which I am changing over to the quad rings but in my assembly there is an extra large O-ring just sitting in the OD radius of the piston above where the ring groove would be (If I had rings)..I'd post a picture if I could or knew how.

Thanks again

I did figure out I can post pictures to my profile page and have posted a couple pictures of the a gear strut disassembled with the extra O-ring. If anyone knows the reason for it or has a parts manual calling it out please let me know.

Thanks!  

It appears someone installed that rubber ring to act as a bumper or cushion for when the piston reaches its upper limit when the weight is off the gear. Not necessary but it won't hurt anything. 😊

Get rid of it. That O ring isn't doing anything but gumming up the works. And if it comes apart from doing a job its not designed for, the trash is just floating around in your strut.

Thanks!

I remove the extra O-ring and reassembled the struts with quad rings.
