Question:
Do you carry a replacement Grease seal for an old National seal part number 5009? I have an older, homemade trailer with what appear to be mobile home axles.

Expert Reply:
In order to find a seal that will work you will need to take a few measurements. You will need the outside diameter of the seal plus the outside diameter of the surface that the seal will ride on. Check out the picture I attached that shows what you will need to measure. You will want to use a dial caliper, # PTW80157, to get exact measurements.
The 5009 National number did not cross to any of the seals that we carry, so the measurements will help us in finding a replacement.
