Stuff the seal in place then use a smooth steel rod to work the Teflon seal flat into the seal holder. Do this before you put the seal holders into the tractor case. If you ruin a Teflon seal, they are in stock at all Deere dealers.
I give you the part numbers in my paperwork. Made in USA with as much effort and care as we could find. Here is a testimonial from a fellow Deere owner.
Dear patspartsstore, I just finished installing your kit. Fit was perfect inner and outer, i also believe this to be superior to factory.
When i installed my kit, i took the drawbar support completley off. The front bushing was terribly wore, 1/4-3/8ths inch slop, never replaced in 53 years, 4010. Without replacing this bushing i think the seals in a short time would leak again from the slop, this support is very easy to R and R. I also think you should send out your kits with the teflon seal and oring installed, but a vice grip very, very gently clamped held the teflon seal to make installation a breeze.
