    Ah OK! I remember that someone used red silicone rings, I wrote here some months ago....

    I DID!!!!!!!
    I knew the damn thing would fit. They make em the right size for a reason. I forgot how much overlap there was but it seems like it was close to an inch.

    This has been superseded by a X-ring, the quad seal you mentioned.
    It comes as a length of material, you need to very carefully cut it with a razor blade to length, so it just fits in the groove.
    It's not supporting the strut, so if you cut a bit too much it still works but it's best to get it ~1% too long and a snug fit in the groove.

    A santé,

    Good advice Glen. Looking at the Piper drawing the length of the wiper to be purchased is 5-1/4".
    The one I cut a few months back just touches the 5-1/2" mark. I cannot say that that is where I was losing the oil, probably not..er Most probably not.
    This time around I started my tear down while my mind was occupied elsewhere and I pulled the bolt at the block/tube assy. and gave it a couple wacks then woke up to what I was doing. Well without knowing I caused the plug, that is also attached by that bolt, to slide up to the other end of the tube. When I pulled it apart there lay this plug that I never saw before, ha! It does not show the plug in the Piper Tri-p manual and the way the Piper drawing is it is kinda hard to pick up there. You would think that the plug's O-ring would be included along with the other serviceable items. I am surprised oil does not pour out the bottom when that O-ring dies?
    Am I missing or confusing the layout? I waited for this to really bother me before posting another dumb thought here but most likely not long enough.

    I didn’t have time yet to test the nose gear, till now no leak. After 5 days the pressure is the same.
    We will see.
    Probably this weekend I will do some flights.

    Bill,
    Can you post a pic, a sketch, the Piper drawing with some scribbles indicating this mystery plug of which you speak?
    Uncertain what you are talking about.

    Best,

    The Plug looks like a little piston and its wrist pin would be the bolt that holds the chrome tube to the aluminum block. It's top faces up and has an O-ring instead of a piston ring.
    I sure haven't yet figured out what keeps the pressure back but I am pretty sure it is not the o-ring in the plug because mine was old, hard and flat on one side so it would have failed my bubble test a few days ago and it is still holding strong.
    The drawing must be deceiving. A good cut away pic would be nice. Anyway, the plug must be there to keep it from getting packed with dirt/corn stalks...er whatever the farmer has in that field.

    Just a follow up on all this. The plane has sat in one spot, never moved since install, for 22 days. I found that the strut had dripped oil onto the tire. The oil did not come over the block the fork attaches to it dripped straight down from the center of the tube. I want to say that there must have been a film of oil inside the tube that finally worked its way down to the bottom because that old o-ring is so beat up it wouldnt hold back nuthin.
    I was actually looking for a recent thread about nosewheel bearings because it would be a good place for me to offer a cheap upper bearing for those in need. I bought 5 for less than the price some people charge for one. Paid full for the lower, ouch!
    B545DD lower bearing for the low price of $15.00 you pay shipping. (53 gram bearing wrapped in 100 grams of paper, ha.)
