Dripless seal on f35 -- looking for a photo

Postby xluke1 » Thu Apr 23, 2015 6:48 pm

I am probably looking for a needle in a haystack but I have a leak while running on my PSS dripless shaft seal on my Pedrick F35. On inspection, the retaining collar/seal (the one w/ set screws) is quite far forward. I'm wondering if it has slipped forward allowing tension to come off the bellows, as opposed to some other problem. I was going to try to adjust it aft per PSS's instructions, but wanted to get an idea as to how far aft it should be. Does anyone have a photo of the PSS they coudl send me so I can estimate how far from the shaft to transmission coupler should be from the collar/seal. Right now it is probably less than an inch which makes me wonder if the bellows are under-compressed.

Or, I'm open to other suggestions that may explain why it started leaking at many RPM ranges.

Had same problem with my F35. The front seal had moved forward releasing tension on the carbon/graphite bearing. I just loosened the set screws and compressed the bellows about 1 inch and retightened set screws. Don't forget there are two set screws, one on top of the other.
