Thanks for the great test Joe. I've got this one bookmarked now.
<br />I only test these older gearcases with around 5psi of pressure - it sounds to me like you're holding pressure just fine. It's possible it's failing on vaccum though - just unlikely. Due to the gearcases only having single lipped seals, they normally don't hold much vaccuum.<br />The simple fix for seal worn shafts is a thing called a 'speedi-sleeve' manufactured by Chicago Rawhide and sold by bearing/seal parts houses. They're thin stainless sleeves that fit over the shaft in the worn area, increasing the diameter there only slightly. Just about any machine shop can install one for you, but you need to remove the shaft first.
