Hub Cap Window Kit with Center Plug - Hub Oil Sight Window Repair - National WK5912 180.10626

Get the hub oil level back in sight with this Hub Cap Window Kit with Center Plug distributed by FleetPro Parts & Tires. The window is the only thing that lets a driver check hub oil at a glance during a pre-trip, and once it is cracked, clouded or weeping there is no way to know whether that wheel end still has lube in it until something gets hot. This kit replaces the window and includes the center plug, 180.10627, so the cap goes back together complete instead of half repaired. We stock these heavily right here in our Hanover Park, Illinois warehouse to ensure lightning-fast shipping for fleets, diesel repair shops, and owner-operators nationwide.

Oil Level at a Glance: The Hub Cap Window Kit Advantage

A hub cap has two jobs. It closes the hub and keeps the lubricant in, and it lets you verify the oil level without pulling anything apart. This kit restores both of them. Instead of scrapping a serviceable cap because the window failed, you rebuild the cap you already have and put the wheel end back in service the same afternoon.

The kit suits steer, drive and trailer axle wheel ends and is the right call when the cap body itself is sound but the window is cracked or has gone cloudy. Where the cap flange itself is damaged and leaking hub oil, replace the whole cap instead. Manufactured by Automann to Fleet Standard specifications, the kit weighs 0.1 lbs and includes the center plug so nothing else has to be ordered to finish the repair.

At FleetPro Parts & Tires, we know a wheel end you cannot inspect is a wheel end you cannot trust. This Automann kit is a direct replacement for the highly searched industry number National WK5912.
