Changed Shaft seal - leaks worse now - where did I goof?

Hello everyone, OK so I ordered and received my shaft seal from ACkits.com and I really didn't have any problems changing it out. I made sure everything was a clean as possible and the only time I became concerned is when I had to use some oomf (force) to push the seal over the front of the shaft, down past the splines to it's stop. I lubricated the seal and shaft quite a bit just before installation too. I buttoned everything up, accept the clutch and coil, and drew a vacuum. I can hear the leak at the seal and if I cover up the nose of the compressor with my hand, I can feel the suction on my palm. Did I ruin the seal by installing it over the splines? If so, what is the proper method?

Thanks,
Howard

Sorry to read it did not work. IMO shaft seal replacement is hit or miss! This is the main reason I do not promote the replacement of them as others do. With a knock off new compressor being $175.00 dollars. It's a risk doing a seal and chancing the loss of refrigerant. To me it sounds like you did things right minus the use of a shaft protector. But not all compressor models will allow this use of them.

Yup, as Tim says gotta use the shaft protector... the splines will tear a new seal up.
