[QUOTE="Pappy, post: 472612, member: 3278"] [size=5]First off you need to find the seal that is leaking. There is a chance that it is or was a fill/drain screw seal and nothing more. Use soapy water and a bit of pressure in the gearcase. How to get pressure? Use a blowgun tip but hold it well away from the top fill level screw. You only want a couple psi in the case. You should see bubbles around the affected seal. I use a gearcase pressure tester but well aware most folks don't have this option. [/size] [/QUOTE]
