It’s not very often that my lead mechanic is stumped but this one has him perplexed. He is replacing the “O” rings in a Zierco 204 boom assembly seal Elbow. The Zierco parts breakdown shows a 2 “O” Rings #20410 and #20406. The Kleen-rite breakdown show them to be a #BO0092 O Ring (Yellow Mark) and a #BO0066 O Ring/Elbow Seal. The breakdown on the Zeirden web is also unclear as to which “O” Ring goes where. Does anyone know which “O” Ring goes where? The Yellow marked “O” Ring on the top or bottom?
