solid products and fast shipping to mn
by Bryan from Big Lake, Minnesota on April 17, 2011
Guessing if your ordering this you already pulled the gimble bearing. To get this seal out the gimble bearing needs to come out, and chances are your not getting it out without ruining it. I would suggest if your not already planning on it to replace the gimble bearing at the same time. I used a slide hammer to pull this and the gimble bearing out. Seal comes out with ease, bearing was a little more banging with the slide hammer. Project started by going after the drive cable, but ended up replacing the gimble bearing and seal at the same time since the bearing was not 100% smooth when turned by my fingers. Would have only been a matter of time before I needed to pull it all apart again. Best part is how fast iboats gets my orders to me. Ordered on a Wednesday night, and parts delivered Friday afternoon with the standard shipping.
