How do you drain the oil on an oil bath wheel bearing? Couldn't find anything in the archives. The book is silent, but in looking at the parts picture, it appears the 6 bolts on the hub need to be removed, drop the hub, and all the oil will run out the front.
Am I assuming correctly? Will I need to get a new gasket for the hub before attempting? Time for an oil change on the Eagle wheels.
Thanks,
David |

with oil-bath style bearings, there will still be trapped oil in the cavity between bearings.... if you remove the aluminum 6-bolt cover you'll get some oil... if you park the bus on a severe slope, you'll probably drain more....and some will wick out between the rollers in the outer wheel bearing...i have seen some hubs that have a small pipe-type plug that will allow some oil to be drained...but you'll still only get maybe half of the oil out of the hub |

Does your hub has a small cast-in raised flat on the side with a small hex head plug installed? If sooss, then you MAY have oil bath front bearings.
If not, then it is POSSIBLE you have the grease type front bearings, which are kinda like that on a car only much bigger: with inners and outers and seals. |

It is called a hub seal...but you are assuming correctly, the six bolts need to be removed...
as Jim says you won't get it all, but quite a bit will flow out of the hub and yes, replace the hub seal gaskets.
If you can find them, the rubber fill plugs too.

If you are going to go to the trouble, why not go all the way. Once the hub nut cover is off, why not remover the nut and pull the whole thing? This is a great opportunity to clean and take a good look at the bearings and races.
For the small additional cost it would also be a good time to replace the rear hub seal, and get a good look at the brakes and drums. Besides extra time the only cost to all of this is that of a rear seal, and when you are done you have confidence everything is right. |

last fall i dismantled 25 GM transit that had oil in the front hubs, some of the buses had sat for a year. when tqking the hubs off i found that nearly half of them had rust on the top of the bearings from sitting however the ones that had grease in the hubs were in great shape with NO rust. needless to say i changed back to grease as my bus may sit for 3 months without moving. |

I have ran across the same thing Mel, I would guess it is from condensation, since rain cannot get in there. Drive one with oil that has sat for a year, and the nice clean looking oil will be rusty milky crap in just a few miles. It is NOT easy to clean it all out and get it lubed again either. |
