Seal 45x60x8 NBR final drive rear wheel output (alternate)

This is an aftermarket seal. Ural lists the original part as "Seal NAK TC 02861 NBR DL 45x60x8" and IMZ-8.128-05039. This seal presses into the final drive case and seals the driven gear hub, close to where the final drive mates with the splines on the rear wheel.

For both 2WD and 1WD final drives back to at least 2007. If your bike -- or your final drive -- is older than that, you might want to clean up your old seal so you can read the dimensions on it, first.

We also have an FKM (aka Viton) version, not that your final drive should ever get hot enough to reap the benefits.
