Today, we're going to review part number 10-63. This is the Redline Unitized Oil Seal for trailer hubs. A unitized oil seal is a dual action seal. The way it works is the inner part which is this part right in here. It will actually stay fixed on the spindle and this outer casing right on here will rotate with the hub. This type of seal has less wear and tear and provides better leak protection.
A unitized oil seal is mainly used on hubs that will use an oil bath lubricating system. This particular part number is used on Dexter 8000-pound axles and their 9000-pound axles up until 10 of 1989. A few measurements on this is the overall; our outer diameter on this will 3.376. The inner or inside diameter measured right here would be 2.250. Also, if you go to the product page for this part number, we will list a chart and there will be a seal cross reference chart.
Basically, that chart is if you look on it, it will list all the grease seal or their oil seal manufacturers and their part number that will match this part number that we have right here. That should do it for our review on part number 10-63.
