Re: Fan Hub
# 1 oil
# 2 whatever engine oil you use # 3 assemble you make a gasket and put fan back tighten all bolts. Turn fan until the screw is at 12 0'clock fill with oil now turn fan so that oil fill is at 3 o'clock - excess oil will now drain out in a catch pan put fill screw back and your done. Its kind of like a mini oil pump as the fan turns it churns oil around. Back in the shop days that was part of the oil change and grease job and lubing all door striker plates with this waxy white grease stuff remember that stuff? sam |

Re: Fan Hub
Just so everyone is aware, the unit pictured is not for an 8BA (car), but probably for a truck. The car uses a sealed bearing (from some other make water pump) that has no provision for lubrication, but can be replaced.

The bearing that "tubman" speaks of is very similar to this one. DD |

I believe that you are supposed to turn the hole straight down to the 6 O'clock position to drain out the excess oil. |

Per the Maintenance Manual, published by Ford Motor Co, It says, use one oz of light engine oil, then turn screw hole down, and drain.

Re: Fan Hub
I drain the fan hub on my 59AB at the 6 o’clock position, as there is a “stand pipe” in the hub that sets the correct level. I think a drain at 3 o’clock would leave too much oil in the hub, resulting in leakage past the shaft.

Re: Fan Hub
Thanks for the tips and advice everyone. Interesting that this unit appears to be from a truck application.
All I can say is it came out of a '53 Customline many years ago . Here in Australia all of our flathead engines were sourced from Canada. I query if they used the truck style units on the cars as well? |

Re: Fan Hub
I just noticed another curious feature of this pulley arrangement and that is there appears to be no seal at the back of the pulley where the shaft protrudes.
Looking at the diagram on the Vanpeltsales page there appears to be no seal there either. I gather it relies on the various drillings and machined grooves to provide drainage. Any comments on this? |

Gotta remember that once you oil it, then DRAIN it, there ain't much oil left in the thing to speak of, or to LEAK of, either. DD . |

Re: Fan Hub
Fred. You are correct, there is no seal in the hub. The groves in the shaft and the direction of rotation keeps the oil in the hub. That is why the correct level is important in preventing a rust treatment job in your engine compartment.

Re: Fan Hub
A further question about these hubs . I have made up a new gasket for the front plate and performed a trial fit.
The question is how much end-float should this shaft have inside the pulley? Mine has 0.030" float. That seems a lot to me . Is there a specification for this? |

Re: Fan Hub
One thing to consider is that if there is oil in the hub and you set it down on your workbench, one way or the other, the oil will leak out. I do not remember which way, but I think it is if you set it down with the fan blades up.
