Today we're gonna take a look at the replacement bearing race for the number 1779 bearing. Now the race will provide the smooth surface for the bearing to roll on inside of your trailer hub. Typically if you have to get new bearings it is a good idea to replace the races along with them. The races are actually pressed into the trailer hubs themselves. Now the replacement part will use the industry standard number. In this case, this race would be part number 1729 and again the matching bearing that goes in this is the 1779 which we do sell separately on our website. The critical measurement on this bearing race is the outer diameter which is measured edge to edge just like that.
What we're gonna do because the measurement is usually in thousandth, is we're gonna use a digital caliper. I'm gonna zoom in here so you'll be able to see the measurement. We'll go ahead and get that and then you can see your outer diameter on this bearing race is gonna be right at 2.240. That should do it for the review on the replacement bearing race for the number 1779 bearing.
