108-1 Gear Strut Rebuild (No Rings / Extra O-Ring)
I'm new to the club, Stinson ownership and the forum.
I am in the process of rebuilding the gear struts, I have them disassembles and a bit confused.
We do not have rings but we have an extra O-Ring where it doesn't appear to be doing anything.
I assume we probably have an older model 108 (S/N:2070) or at least older model gear struts but I'm having no luck finding info on this version.
Does anyone have any information they care to share?
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.
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.
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.
I remove the extra O-ring and reassembled the struts with quad rings.
