Thread: Bearing check

SeaRay, also get the size off the spindle where the seal runs. That's the step up behind where the inner bearing runs. Bearing, spindles and hubs have somewhat been standardized by the carrying capacity of the axle, but go by the measurements off your spindle to be sure because yours could be different. Since you will have to pull the hub to get the measurement it would be a good idea to try fit the new one before you put it back together.

I'm looking at a chart that shows:
5 lug on 4.5" circle 1250 pound capacity inner bearing 1" outer bearing 1" seal 1.250
5 lug on 4.5" circle 1350 pound capacity inner bearing 1 1/16" outer bearing 1 1/16" seal 1.25" or 1.50"
5 lug on 4.5" circle 1750 pound capacity inner bearing 1 3/8" outer bearing 1 1/16" seal 1.72"
5 lug on 4.5" circle 2750 pound capacity inner bearing 1 3/4" outer bearing 1 1/4" seal 2.13" or 2.25"

0.433 can be enough to push by a damaged seal.

Granted, but I believe the most common cause of pushed out seals is pumping too much grease in to start with and it blew out the seal. Ask me how I know!
