Rebuild kit from Deere came with a hard plastic type seal to go inside of the rod guide now wiper seal wil not stay in the end of the rod guide , pushes out with any or no pressure ? Leaks worse than befor rebuild? Repair manual shows a orang in side rod guide . 3 wiper seals later , need some help! Thanks

You either put the main rod seal in backwards, cut it in installation or forgot it altogether

If the wiper blows out the rod seal under it is the problem

The orange ring is only used temp for removing the gland, after it is pushed in to expose the groove the orange ring needs to go in the groove, then yank the whole assy out
