    Oil Bath Hubs FAQ

    TROUBLESHOOTING GOLD OIL FILLED HUBS

    Color
    It is recommended that you change the oil in the GOLD system after 20,000 miles or every 2 years unless oil becomes a milky color. If no leak is observed, then replace oil in system.

    Fill Level
    Check the oil level in the hub through the inspection window in the front of the protector. The window should indicate that the hub is completely full of oil with no more than a dime-sized air bubble. If the oil level is low, determine source of leak and repair.
    Note: If Necessary, Gold oil filled hubs can run with as little as ¼ the normal oil level and still provide adequate lubrication to the bearings. However, partially filled hubs may suck in water if submerged.

    Leakage
    A very slight amount of oil seepage at the rear seal is normal and necessary to lubricate the wiper lip of the seal for long life and sealing contaminants out. Excessive oil leakage, more than a few drops, will require the hub to be removed and the oil seal to be replaced.

    REPLACING SEALS

    The hub or rotor must be removed from the axle and the seal forced out. It is impossible to remove the seal without damaging it. Therefore, when you remove the seal, plan on replacing it. Because seals are a high quality design not widely available, you will need to obtain a replacement from the dealer, a bearing supply company, the trailer manufacturer or Unique Functional Products. Seals installed at the factory may have a hypalon (blue teflon-like) coating on the outside diameter. If your replacement seals do not have a hypalon coating then apply a thin film of Permatex #81160 (Red) High-Temp RTV Silicone Gasket Maker on the seal outside diameter, and hub bore in order to seal it prior to installation. Flat Rate for seal replacement is .7 hrs per brake hub and .5 hrs per non-brake hub at posted Dealer shop labor rate.
