happy memorial weekend everyone :usa i have a question i was hoping some one could answer. i bought a seal kit to repack my loader lift cylinder. the problem is, the seals that came out of the cylinder are different than what the new kit contains. part #9 case part #G107923, is what is in the photo " SEAL u cup, piston rod, wide, with O ring " the thinner of the two pictured new seals is not part #10 from the illustration. i talked to the place i bought them from, they didn't know much other than the kit i received was complete. so i guess my question is, how do the two new seals mate up? do i put the two U groves facing each other? thanks guys :drinkup
Well, I'll give it a wag wrecd. Hard to tell in the pic, but your old one looks like a Poly Pac with an o-ring loader in the center of the cup lips. The new one is a typical Urethane U-cup seal, very common seal for the gland on hoe cylinders. The thinner u cup seal is called a buffer ring seal, which goes in a seperate groove in the gland, the groove closer to the inside of the cylinder. It helps control shock loads from putting excessive pressure on the other u-cup seal. This set up will work fine replacing your old Poly Pac seal. Both of those seals would be installed in the gland with the U of the seal facing inward, toward piston of cylinder.
Thanks ATCOEQUIP !
Your welcome bro. What kind of piston seal does it have? In the illustration, looks like a urethane or teflon ring seal with an o-ring loader. Is that seal ring flexible? Or does it feel rather stiff? Like it won't stretch easy.
im not sure what the original seal is made of, its off of a 580se. the old seal is very brittle and stiff, it pretty much crumbles away if bent. it did have an o-ring in the groove. the new seal is pretty stiff and definatly not stretchy. i had a hard time squeezing it into its groove edit: i misread your post. the piston seal is not stretchy. not sure what its made of.
Yep, those type of piston seal rings are rather stiff. Now that you've got it on the piston, is it rather loose? Have you already installed the piston/rod into the cylinder?
i did put it all back together. seems to be working great now i found a slick way of installing a piston seal on this forum, i think it may have been from one of your posts ATCOEQUIP. heat up the piston and seal in some hot water and ease the seal on with some picks then strap the whole works in a ring compressor and drop it in the freezer for abit. this is the second time i tried this way and both times it worked perfect. seal was nice and snug. its amazing some of the tricks and techniques you guys come up with. :notworthy i only have one more loader lift cylinder and both stabilizer cylinders left to repack now . thanks again ATCOEQUIP :drinkup

something isn't right. following your posts and have yet to see pictures or illustrations?
Be patient carogator, pics still being cleaned after the website was hacked a week ago. I'm sure they are working on getting the pics back on forum, just gonna take some time.
