Given the bearing numbers that you have, you will need 1 of 2 possible seals. You will either need 10-10 seals # RG06-090 or 10-36 seals # RG06-070.

The difference is the dimensions. The 10-10 seals # RG06-090 have an inner diameter of 2.125 inches and outer diameter of 3.376 inches.

The 10-36 seals # RG06-070 have an inner diameter of 2.250 inches and outer diameter of 3.376 inches.

The inner diameter is the key. If you measure the inner diameter of an existing seal or the spindle diameter where the seal rides then that will determine which seal is correct. Use dial or digital calipers to take the measurement because it has to be as accurate as possible.

I was unable to find 512136-4 in our seal cross-reference chart or in any of the other places we usually find information.
