I have tried 1/8" round teflon packing rolled flat then spiraled in place of the steel bush, seals well, but i don't trust it. can envision it working it's way out on the road in the middle of nowhere.
I am leaning towards trying a teflon tubing, [tefzel],exellent mechanical resistance, good chemical qualitys, which comes in the correct O.D. but the I.D. is .230"- great if you have a worn shaft.
Any thoughts would be appreciated!
